Whole-body MRI is widely available, non-ionizing and rapidly acquired, and inexpensive relative to PET CT. While it has many advantages, WBMRI is non-specific and, when compared to PET CT, is less sensitive. This article expands each of these issues comparing individual modalities as they refer to specific cancers.[...]© Thieme Medical PublishersGet connected:Table of contents  |  Abstract  |  Full text (Source: Seminars in Musculoskeletal Radiology) Seminars in Musculoskeletal Radiology journals http://www.medworm.com/rss/comments.php?id=3361373 Sat, 13 Mar 2010 15:20:45 +0100 3361373 http://www.medworm.com/index.php?rid=3361372&cid=s_36625_37_f&fid=36625&url=http%3A%2F%2Fwww.thieme-connect.com%2FDOI%2FDOI10.1055%2Fs-0030-1248706 This article presents an overview of emerging clinical applications of WBMRI emphasizing its role in the assessment of musculoskeletal ailments, ranging from the assessment of arthropathy through to body composition research.[...]© Thieme Medical PublishersGet connected:Table of contents  |  Abstract  |  Full text (Source: Seminars in Musculoskeletal Radiology) Seminars in Musculoskeletal Radiology journals http://www.medworm.com/rss/comments.php?id=3361372 Sat, 13 Mar 2010 15:20:45 +0100 3361372 http://www.medworm.com/index.php?rid=3361371&cid=s_36625_37_f&fid=36625&url=http%3A%2F%2Fwww.thieme-connect.com%2FDOI%2FDOI10.1055%2Fs-0030-1248704 This article reviews the role and imaging appearances of muscle diseases at MRI, specifically emphasising the role of WBMRI in global assessment of muscle abnormality, and in particular its role in determining distribution and extent of muscle abnormality.[...]© Thieme Medical PublishersGet connected:Table of contents  |  Abstract  |  Full text (Source: Seminars in Musculoskeletal Radiology) Seminars in Musculoskeletal Radiology journals http://www.medworm.com/rss/comments.php?id=3361371 Sat, 13 Mar 2010 15:20:45 +0100 3361371 http://www.medworm.com/index.php?rid=3361370&cid=s_36625_37_f&fid=36625&url=http%3A%2F%2Fwww.thieme-connect.com%2FDOI%2FDOI10.1055%2Fs-0030-1248705 Semin Musculoskelet Radiol 2010; 14: 037-046DOI: 10.1055/s-0030-1248705ABSTRACTMultiple myeloma is one of the most common hematological malignancies and accounts for significant morbidity and mortality. In the past, detection of myelomatous deposits by radiography was the main method of radiological assessment in this disease. However, in recent years the introduction of whole-body imaging techniques, specifically low-dose whole-body computed tomography, whole-body magnetic resonance imaging, and positron emission tomography, has facilitated a more comprehensive assessment of this heterogeneous and often diffuse disease. Each of these whole-body imaging techniques has specific applications and limitations in the assessment of multiple myeloma that the interpreting radiologist and referring...

Specific conditions additionally affect the extensor mechanism in adolescents during growth and maturation, and in older patients as a result of degeneration. Prior to the advent of magnetic resonance (MR) imaging, the specific anatomical-pathological cause of anterior knee pain was often uncertain, with diagnosis limited to clinical examination and conventional radiographic assessment. MR imaging allows for the accurate and specific diagnosis of pathology of the extensor mechanism, impacting on decision making and clinical treatment of such conditions. In this article the anatomy, normal MR appearance, and common pathological conditions of...

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. MS-CT scan is the method of choice in the assessment of bone stability and allows for evaluation of fracture risk. ...

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. This is mainly because in MRI, marrow infiltrates are displayed before osseous destructions occur. New imaging guidel...

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.

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.

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.

This is significant due to superior outcome results of surgery intervention in hip dysplasia or femoroacetabular impingement in patients not exceeding early degeneration. This emphasizes the need for accurate and reproducible methods in evaluating cartilage structure. In this article, we discuss the impact of the most recent technological advance in MRI, namely the advantage of 3-T imaging, on diagnostic imaging of the hip. Limitations of standard imaging techniques are shown with emphasis on femoroac...

Several conventional two-dimensional (2D) and three-dimensional (3D) approaches show changes in cartilage structure. Furthermore newer isotropic 3D sequences show great promise in improving cartilage imaging and additionally in diagnosing surrounding pathologies within the knee joint. Functional MR approaches are additionally able to provide a specific measure of the composition of cartilage. Cartilage physiology and ultra-structure can be determined, ...

Entrapment and compressive neuropathies are a group of distinct syndromes secondary to physical constriction or irritation affecting peripheral nerves at specific anatomical sites in the body. Most nerve entrapment and compressive syndromes derive from an injury to the neurovascular components in a narrow anatomical passage.

They should not be confused with conditions where impingement of cuff and bursa occur on the structures of the coracoacromial arch, so-called external impingement. Some controversy surrounds the true etiology of the soft tissue injuries seen in internal impingement syndromes and whether they are truly the result of impingement. Internal impingement seems to be a normal physiological occurrence with the shoulder in certain positions. Imaging findings in these conditions include undersurface partial-thickness c...

Such incidental findings can be problematic for the musculoskeletal imager, both in terms of assigning clinical significance and determining the appropriate workup for a given abnormality. In this article we discuss the normal MRI appearance of the various pelvic organ systems as well as normal variants, emphasizing those that can mimic pathological processes.

The joint is difficult to profile well on radiographic views, and therefore the radiographic findings of sacroiliitis are often equivocal. Computed tomography images can usually show the findings of sacroiliitis and osteoarthritis earlier than radiographs. Magnetic resonance imaging performed with proper sequences is excellent for diagnosing even very early sacroiliitis and for following treatment response. The SI joint is often involved in patients with osteoarthritis or one of the inflammatory spondyloarthritides, most notably ankylosing spondylitis. Ankylosing spondylitis often presents w...

Encompassing fatigue- and insufficiency-type fractures, stress fractures of the pelvis are likely underreported. Radiographs are insensitive to stress injuries, particularly those in the pelvis, whereas scintigraphy and magnetic resonance imaging are exquisitely sensitive. In this article we discuss the pathophysiology and imaging appearances of stress injuries of the pelvis and sacrum.

The proximal portions of the hamstring muscles are subject to a variety of injuries and pathology. Many of these entities affect the origin of the hamstrings, including the tendinous enthesis, the underlying ischial tuberosity, and the surrounding tissues. Tendinosis and small partial tears at the origin are the result of chronic attrition. They may be accompanied by bursitis or hamstring syndrome.

Tightness of the posterior musculotendinous structures in the leg limits ankle range of motion and affects an equinus posture of the foot. Increased contact pressures are generated in the plantar foot with weightbearing. The resultant overload of the ligaments and the intrinsic muscles of the midfoot and forefoot is manifest in a variety of pathologic processes. The altered mechanics contributes to, among other conditions, ankle impingement, plantar fasciitis, midfoot arthritis, posterior tibial tendon dysfunction, forefoot overload, diabetic ulceration, and Charcot arthropathy.

In this article we review the information most useful to the practice of orthopaedic surgery obtained from these MRI scans, including sections on ligaments, menisci, articular cartilage, limb alignment, bone, and surrounding soft tissues. We place special emphasis on evaluating the postoperative knee, ligament grafts, cartilage integrity, and other conditions that present challenges to both orthopaedic surgeons and radiologists.[...]Copyright © 2007 by Thieme Medical Publishers, Inc., 333 Seventh Avenue, New York, NY 10001 USA.Get connected:...

Although traditionally perceived as a condition occurring in the elderly, the detection of early hip arthritis in the young population must not be overlooked. The detection of subtle anatomical abnormalities giving rise to hip pain continues to pose a challenge. Recently, femoroacetabular impingement has been recognized as an etiological risk factor for early arthritis and hip pain in the young adult. The recent advances in imaging technology and the potential for joint-preserving surgical procedures allow early diagnosis and potentially better delivery of care to these patients. It is hence imperative that all those in the musculoskeletal community in...

Variational anatomy of the shoulder combined with the complexity of physical examination makes this difficult. Physical examination of the shoulder often leaves the surgeon with more than one working diagnosis. Imaging studies of the shoulder are more valuable if used to confirm a working diagnosis as opposed to reading the study in a vacuum. Clinical correlation should also be considered for any and all findings on an imaging study. Collaboration of the surgeon and the radiologist is essential in reducing the number of over-reported findings that are clinically insignificant....

Proper radiographic diagnosis and appropriate intervention requires a thorough understanding and appreciation of developmental anatomy. As the pediatric elbow matures, it transitions from multiple cartilaginous anlagen through a predictable pattern of ossification and fusion. When children sustain trauma to the elbow, they may have a limited capacity to communicate specific complaints and are sometimes difficult to examine reliably. Furthermore, the presence of multiple growth centers, and their variability, makes radiographic evaluation of pediatric elbow injuries particularly...

Preoperative consultation with orthopaedic surgeons providing treatment is appropriate for radiologists performing percutaneous tumor biopsies because biopsy tracts need to be resected along with the specimens in cases of primary malignancy.
