A large number of SARS patients experienced large joint arthralgia, although this was, for the most part, not associated with any abnormality on magnetic resonance imaging. The main musculoskeletal complications of SARS were osteonecrosis and reduced bone mass, and these arose not from the disease per se but as a sequel to treatment of SARS with high-dose steroids. SARS patients were almost universally steroid naive with no other known predisposition to osteonecrosis. Prevalence of osteonecrosis in SARS patients treated with steroids ranged from 5% to 58%. Osteonecrosis most commonly affec...

The disease has been increasingly recognized around the world due to the increased levels of travel and population movement. Clinical manifestations of melioidosis range from fulminant septicemic illness to an indolent local infection. The disease often involves multiple organs, including the lung, spleen, liver, and other visceral organs. Musculoskeletal infection is usually seen as a part of multiorgan involvement, but localized musculoskeletal involvement may occur. The most common manifestation of musculoskeletal melioidosis is septic arthritis, followed by osteomyelit...

This infection is endemic in northern Mexico, the southwestern United States, and parts of Central and South America. The risk factors include ethnicity (especially African and Pacific Island ancestry), male gender, and immunosuppression. The primary infection occurs in lungs, but fewer than 40% of patients are symptomatic. Fewer than 1% of infections result in disseminated disease, which may involve any organ. Skeletal infection occurs in 10 to 50% of these patients and is frequently multicentric with axial skeleton involvement. The diagnosis ca...

Most patients are diagnosed and treated in poorly equipped government-funded hospitals and clinics that have insufficiently trained staff and are barely operational. Any available imaging equipment is likely to be functioning suboptimally and be poorly maintained. The root of the problem is usually a lack of know-how and a quality culture, combined with insufficient basic equipment and infrastructure. Radiological imaging is an essential aspect of primary care and used in the critical diagnosis and management of trauma,...

Imaging-guided biopsies have gained increased acceptance to obtain various types of tissues for diagnosis. Under image guidance, biopsies are done percutaneously, usually under local anesthesia. They are relatively safe, and complications are significantly less compared with open biopsies. In this article, we review the planning, indications, technique, and complications of imaging-guided percutaneous biopsy performed for musculoskeletal infections.[...]© Thieme Medical PublishersArticle in Thieme eJournals:Table of contents  |  Abstract  |  Full text (S...

It also reviews the imaging differential diagnoses, including other infections and malignancies/metastases. Conventional radiography is of key value in the diagnosis of musculoskeletal TB. Computed tomography, magnetic resonance imaging, and bone scintigraphy also play key roles in the early detection of disease and in demonstrating the extent of disease process and soft tissue involvement. Because delay in treatment significantly reduces the cure rate and increases the rate of complications and morbidity, early radiological diagnosis of TB is of paramount importance for appropriate management.[...]© Thieme Medical PublishersArticle in Thieme eJournals:...

It is characterized by a granulomatous reaction in the reticuloendothelial system. Because it affects several organs and tissues, it may have various clinical manifestations. Musculoskeletal involvement is one of the most common locations, and the frequency of bone and joint (osteoarticular) involvement of brucellosis varies between 10% and 85%. Osteoarticular involvement includes spondylitis, sacroiliitis, osteomyelitis, peripheral arthritis, bursitis, and tenosynovitis. The most common osteoarticular finding in children is monoarticular arthritis, mostly located in the knees and...

They are often found in immunosuppressed or patients with the acquired immunodeficiency syndrome or in patients with a history of travel to an endemic region. Infections often present with multifocal chronic osteomyelitis or chronic mono- or polyarthritis resembling osteoarticular tuberculosis. A clinical clue to the correct diagnosis is the presence of overlying skin sinuses. Radiologists can suggest the correct diagnosis with a good clinical history, although a biopsy and/or fungal culture is usually necessary before beginning treatment.[...]© Thieme Medical PublishersArticle in Thieme eJournals:Table of contents  |  Abstract  |  Full text ...

Musculoskeletal system accounts for 25% of extrapulmonary TB. Most of the musculoskeletal TB involves the spine. TB of peripheral joints and tendons occur infrequently, but if untreated, it can cause serious joint and tendon destruction as well as spread of the infection to the surrounding bursa, muscle, and other soft tissues. The diagnosis of TB of joints and tendons is difficult due to the nonspecific clinical manifestations and imaging features. Concurrent active pulmonary TB is present in <50% of the patients.

Because most patients have anatomical changes related to surgery in addition to postradiation and postchemotherapy changes, the radiologist must systematically and critically evaluate all available radiographs, sonograms, computed tomography, magnetic resonance imaging, and positron emission tomography/computed tomography scans to best differentiate normal posttreatment changes from residual or recurrent musculoskeletal tumor. Comparison with presurgical and postsurgical imaging is very important to detect subtle nodular tumor recurrence. Because postoperative fluid collections are relatively common, the ...

Using magnetic resonance (MR) T1-weighted images, fat appears light gray and water appears dark gray. Black or low signal structures include normal cortical bone, bone islands, hemosiderin deposits, calcification, ossification, metal artifact, gas, and foreign material. Reactivation of bone marrow reduces the signal of fatty marrow. Additional sequences and supplementary imaging with conventional radiographs and computed tomography are often helpful in determining the nature of the low signal lesions.

Prevalence and the most common sites of insufficiency fractures and their clinical implications are discussed. Insufficiency fractures are due to normal stress exerted on weakened bone. Most commonly postmenopausal osteoporosis is the cause for insufficiency fractures. Additional conditions affecting bone turnover include osteomalacia, chronic renal failure, and high-dose corticosteroid therapy. It is a challenge for the radiologist to detect and diagnose insufficiency fractures as well as to differentiate them from malignant fractures.

The primary diagnostic challenges in this setting are to distinguish osteomyelitis from reactive bone marrow edema, neuroarthropathy from osteomyelitis, and the sterile from the superinfected neuropathic joint. Whereas both osteomyelitis and reactive marrow edema share increased T2 signal, osteomyelitis is confirmed by T1 hypointensity in the bone marrow and reactive edema demonstrates isolated T2 signal hyperintensity.

Timely diagnosis helps prevent permanent nerve damage and its sequelae in terms of functional impairment. Imaging provides additional information to that obtained from clinical tests and EDTs. By allowing direct visualization of the compressed median nerve (MN), ultrasound (US) and magnetic resonance imaging can depict the causes for secondary CTS and describe anatomical variants, such as a bifid MN or a persistent median artery of the forearm, as well as space-occupying lesions including tenosynovitis and ganglion cysts.

The ulnar nerve can be compressed at the cubital tunnel of the elbow and Guyon's canal at the wrist. The deep branch of the radial nerve can be compressed at the supinator muscle at the elbow, and the superficial radial nerve may be compressed at the dorsal wrist (Wartenberg's syndrome). In addition to compression at the carpal tunnel, the median nerve may be compressed at the elbow, related to a supracondylar process or by the pronator teres.

Thickening of the plantar fascia insertion more than 5 mm either on ultrasound or MRI is suggestive of plantar fasciopathy. Ultrasound is superior to MRI for diagnosis of plantar fibroma as small low signal lesions on MRI are similar to the normal plantar fascia signal. Ultrasound demonstrates low echogenicity compared with the echogenic plantar fascia. Penetrating injuries can appear bizarre due to associated foreign body impaction and infection. Achilles tendonopathy can cause heel pain and should be consider...

Up until recently the musculoskeletal radiologist has been fairly limited to using simple proton-density weighted fat-saturated and short tau inversion recovery magnetic resonance imaging scans for assessment of skeletal muscle. Recent advances, however, have resulted in development of newer scans and postprocessing methods that provide much more than gross muscle structure. Scans providing fine structure, muscle function, and metabolism can easily be done using clinical scanners. Here we describe how diffusion tensor imaging (DTI) and blood oxygenation level-...

It may present either acutely or chronically. Acute compartment syndrome most commonly occurs following lower limb trauma, and emergency decompression through open and extensive fasciotomies is the treatment of choice. There is little place for imaging in the acute setting because the diagnosis should be made on clinical grounds, possibly supported by measurements of compartmental pressure. Chronic compartment syndrome is more common, usually presenting with recurrent episodes of pain on exercise. The demonstra...

In addition many of the clinically named syndromes are poorly defined and understood. An understanding of the clinical signs, the normal and variant anatomy, and the often variable relationship between the imaging findings and the clinical findings is essential in the accurate diagnosis and management of these disorders.

Ultrasound and magnetic resonance imaging (MRI) are accurate for diagnosis of acute injuries, but measurements of the extent of injury (cross-sectional area and longitudinal extent of muscle injury adjacent to the musculotendinous junction) have also been shown to correlate with athlete prognosis and recovery time.

Anatomical and functional aspects of the HMC predispose it to injury, including the fact that the muscles cross two joints and undergo eccentric contraction during the gait cycle. Injury most commonly occurs at the muscle tendon junction but may occur anywhere between the origin and insertion. Complete hamstring avulsions require early surgical repair. The principal indication for imaging is in a triage role to rule out or confirm proximal hamstring avulsion.

Use of 3 T for pediatric MSK imaging is still in its early phase, and actual clinical benefits are not yet clear. However, initial reports in adult and our experience suggest that 3 T is better in imaging cartilage and small joints. It provides good quality images even for small field of views, which is advantageous in children. It shows cartilage, ligaments, and nerves better. After optimization, overall examination time is shorter at 3 T, which has the potential to reduce the need for sedation and increase throughput. 3-T imaging has the...

Although radiographs are used as a basic imaging procedure for clarification of suspected focal bone pathologies, low sensitivity has been reported for the detection of limited osteolytic bone marrow destruction. Therefore, skeletal scintigraphy often is used as a more sensitive and integrated method in patients with suspected malignant bone marrow disease.

On radiographs it is often difficult to detect the typical osteolyses in early stages or in regions where overlying structures hamper image analysis. Osteoporosis may be a sign of tumor infiltration, but it is difficult to distinguish from senile osteoporosis. Thus cross-sectional methods increasingly are replacing the skeletal survey, which has been the standard imaging method for a long time. When comparing whole-body magnetic resonance imaging (MRI) with whole-body multidetector computed tomography, MRI is much more sensitive.

However, signal intensity changes in many different diseases presented with diffuse bone marrow infiltration show more overlap than difference, resulting in poor specificity. Therefore, MRI cannot be applied for initial diagnostic purposes in most diseases but should be reserved for staging, monitoring of therapy, and detection of disease recurrence after treatment.

This is especially interesting for challenging imaging regions like the wrist and the hand because of the small size of the visualized anatomical structures; the increase in SNR could then be directly converted into higher spatial resolution of the images. Practically, imaging at 7.0 T poses a variety of technical challenges such as static (B) and radiofrequency (B) homogeneities, shimming, chemical shift artifacts, susceptibility artifacts, alterations in tissue contrast, specific absorption rate limitations, coil construct...

The synovial membrane is the principal site of inflammation in which the inflammatory process enhances capillary perfusion and permeability. Doppler ultrasonography (DUS), using the amount of color pixels in the region of interest, and dynamic magnetic resonance imaging (DE-MRI), using the early enhancement rate and relative enhancement of the synovium, are both able to detect this inflammation in the wrist and hand. Although these techniques are both capable of monitoring synovium inflammation modifications after RA treatment, DE-MRI may be better for quantifying inflammation changes. It yields additional information about joint inflamm...

These two modalities allow a confident assessment of ligament tears and potential diagnosis of associated abnormalities of cartilage, bone, and soft tissues. The interosseous scapholunate and lunotriquetral ligaments and the triangular fibrocartilage complex (TFCC) are the most important structures to consider.

Its clinical impact on diagnostic outcome compared with 1.5 T still remains unclear, however, because no larger case series have been published until now. In addition, the further development of clinical applications is still limited at 3.0 T due to the lack of availability of dedicated coils and the sensitivity of 3.0 T to artifacts. However, especially in the MR imaging of small joints, there seems to be a great potential in improving the diagnostic performance of MRI with increased signal-to-noise ratio by increasing the spatial resolution.[...]© Thieme Medical PublishersGet connected:Table of contents  |  Abs...

Knowledge of the T2 relaxation time is essential to optimize clinical magnetic resonance imaging (MRI) protocols and to enhance the visibility of pathophysiological changes in tissues. The T2 relaxation time of the median nerve is short relative to the T2 of other tissues like white and gray matter, for instance, and it decreases with increasing field strength of the MR scanner. A T2 relaxation time of ~50 milliseconds (ms) and ~20 ms were reported at 1.5 T and 7 T, respectively. Detailed measurements at 3.0 T revealed a biexponential decay characterized by two T2 components, at ~30 ms and ~100 ms, with normalized amplitudes of ~80% and ~20%, respectively. These two components possibly result from spatial compartm...

The diagnostic procedures applied in these situations are electromyography, physical examination methods, ultrasonography, and magnetic resonance imaging. Diffusion tensor imaging (DTI) has been used mostly in imaging the central nervous system (CNS) to visualize white matter tracts. Several studies have shown the clinical applications of DTI in neuronal disorders such as stroke, epilepsy, and CNS tumors. Recently, peripheral nerves have been visualized with DTI.

Triangular fibrocartilage complex (TFCC), scapholunate ligament (SLL), and lunotriquetral ligament (LTL) are crucial to wrist stability. Damage to these ligaments causes changes in bone alignment and altered motion pattern. This may cause pain and eventually osteoarthritis. Imaging techniques of the wrist include conventional arthrography, computed tomography (CT) arthrography, conventional magnetic resonance imaging (MRI), and MR arthrography. Especially, MRI plays an important role in the assessment of TFCC, SLL, and LTL. Therefore, special attention is drawn to normal and abnormal MR imaging appearance of these ligaments in this revie...

It has been postulated that much of osteoarthritis is due to anatomic deformities. Advances in surgical techniques such as the periacetabular osteotomy, safe surgical dislocation of the hip, and hip arthroscopy have provided us with effective and safe tools to correct these anatomical problems. The limiting factor in treatment outcome in many mechanically compromised hips is the degree of cartilage damage which has occurred prior to treatment.
