Reduced strength and muscular pain but no B symptoms were also present. Alterations of the spleen had been known for a long time. Blood examination, laboratory tests and magnetic resonance imaging (MRI) confirmed an aortitis. Concerning the splenic changes neither ultrasound nor MRI could provide conclusive or even pathognomonic findings. Because of an existing pancytopenia and diagnostic obscurity, the patient underwent splenectomy. The histological diagnosis was finally concluded as multifocal littoral cell angioma.

However, to inject contrast media containing iodine and gadolinium at the same time can be a prerequisite for the examination of several organs or organ systems. Unlike other topics of contrast-enhanced imaging procedures, the difficulties encountered with double contrast injections have been widely ignored in the literature.

Thus, seronegative spondyloarthropathy is often misinterpreted as a degenerative disease. The initial radiography of the sacroiliac joints is often normal which results in a delay in diagnosis of sacroiliitis of approximately 3-7 years. STANDARD RADIOLOGICAL METHODS: This illustrates the significance of an adequate imaging method for the early detection of sacroliliitis. METH...

The combination of a sudden platelet drop, the timing of heparin administration and evidence of thromboembolic events by computed tomography (CT) led to the suspected diagnosis of heparin-induced thrombocytopenia (HIT) type II which was confirmed by laboratory testing. HIT is a life-threatening complication of heparin anticoagulation and CT is an important diagnostic instrument for detecting the location and extent of thromboembolic manifestations, thereby enabling the initiation of therapy to prevent further complications.

Radiologe. 2012 Jan;52(1):15-21 Authors: Rosenberg C, Hoffmann CO, Mensel B, Puls R, Hosten N Abstract Laser ablation (LA) is momentarily the only invasive ablation procedure besides radiofrequency ablation (RFA) which can be performed entirely under magnetic resonance imaging (MRI) guidance. The long-term outcome and morbidity profiles are broadly identical for both modalities, excluding the RFA-specific prevalence for skin burns. The technical and logistic disadvantages of LA have been overcome since the introduction of miniaturized two-component applicators. The main advantage of LA is its superior MRI compatibility.

Minimally invasive treatments, such as radiofrequency ablation (RFA), microwave ablation (MWA) and cryoablation are alternative treatment options in a curative and palliative setting. One major limitation of RFA and MWA is the limited size of tumor ablation. Furthermore during the procedure the ablation size can only be roughly estimated using RFA and MWA.

Presenting complaints include back pain and weakness as well as myelopathy and radiculopathy due to compression of the spinal cord or the nerve roots, respectively. Imaging of extradural tumors mostly requires both magnetic resonance imaging (MRI) and computed tomography (CT). Extradural masses and infiltration of the cord can be depicted by MRI and CT depicts osteolytic and osteosclerotic lesions and the extent of osseous involvement.

Whereas previous technical improvements were primarily aimed at the imaging of anatomy with high spatial and temporal resolution, nowadays a trend towards quantitative and functional imaging using computed tomography (CT) beyond the pure depiction of morphology is on the horizon: Currently the focus of technical developments is in the domain of spectral (energy-resolved) CT imaging and ...

The medical history revealed no trauma and no sports-related injury. X-ray examinations of the foot and lower leg showed subcortical increased sclerosis at the medial part of the tibia, the medial tarsal bones and of a bunion. Magnetic resonance imaging revealed corresponding findings with localized edema of the bone marrow within the increased subcortical sclerosis but no indications of subcutaneous fibrosis. The constellation is indicative of melorheostosis, a rare benign sclerosis of bones and soft tissue. Subcutaneous fibrosis and limb shortening are also common.

They had been injected with the contrast medium Thorotrast, which was in use world-wide until around 1950. Thorotrast caused a chronic alpha irradiation mainly of the liver (up to 0.4 Gy/a), spleen (1.2 Gy/a) and bone marrow (0.1 Gy/a). For the Thorotrast patients and their physicians the most worrying problem was the risk of primary malignant liver tumors which occurred in more than 20% of the exposed persons, i.e. 100 times more frequently than in a non-exposed control group. The medical and especially radiological experiences with the management of these patients summarize a general aspect of the problem and can be referred to when managing other high risk groups.

The PSA count, although invaluable in the early detection of PCa, is not being paid for by health insurance schemes, because its indiscriminate use would result in overdiagnosis of PCa which, in turn would burden patients with avoidable morbidity and the mutually supportive community with unnecessary costs. Accordingly, some clinically insignificant tumors are being detected and treated although treatment appears unnecessary. However, more importantly too many significant tumors which...

It seems that in the future women are going to represent the majority of medical professionals. Hence, with the manifest lack of physicians social aspects will also play a bigger role in the choice of the place of employment. In most families the classic role model prevails although women are well educated and men also set a high value on the compatibility of family and profession and would like to take parental leave and work in flexible working hours. This represents a chance, especially for radiology.

The introduction of specialized, organ-related centers is a logical consequence in view of a better treatment quality and a more effective use of resources. The German societies of radiology, vascular surgery and angiology jointly developed a process of certification, which has been successfully applied to more than 100 units in Germany. In this article the terms and results of the process are described and possible effects on the quality and structures of the healthcare system are discussed.

Late diagnosis and neurological involvement at the time of diagnosis are risk factors for long-term neurological deficits. Unremitting back pain with signs of inflammation should give reason to suspect spondylodiscitis and to rule it out by imaging, especially if risk factors such as diabetes mellitus, malignant neoplasms or immunosuppression are present. Magnetic resonance imaging (MRI) is the imaging procedure of choice with high sensitivity and specificity and typically shows hypointense adjacent vertebrae on T1-weighted images with hyperintense signal on short tau ...

The lesion extended from the primary mandibular region into the area of pterygopalatine fossa finally infiltrating the orbital region and the skull base. Histological results could never demonstrate a malignancy with certainty. Due to the patient's poor general condition, the refusal for further surgical inventions and due to the malignoma-like growth pattern radiation treatment was performed. However, this had no effect on tumor progression.

Physiological aging of the brain has to be clearly distinguished from pathological alterations of the brain for reliable and early diagnoses of neurodegenerative diseases. Concerning the speed of the cerebral aging process, significant inter-individual differences can be observed. In general, aging is associated with a decline of cognitive functions. Simultaneously, a decay of the average brain volume, especially in the frontal lobe accompanies the process of aging. Correspondingly, a strong susceptibility for age-related degeneration has been observed in the fronto-striato-thalamic network. Due to increasing age the white matter i...

Infiltrations surrounding the vital part of the tumor may obscure the correct targeting and lead to false negative results in a few patients. Severe complications were not seen in this study, although they might happen in rare cases according to reports in the literature. Therefore CT-guided core biopsies represent an efficient and safe procedure in patients with thoracic lesions.

Computed tomography (CT) scanning of the head should be the first examination performed in any patient with suspected subarachnoid hemorrhage. The characteristic appearance of extravasated blood is hyperdense. Head CT scanning can also demonstrate intraparenchymal hematomas, hydrocephalus and cerebral edema and can help predict the site of aneurysm rupture.

High quality imaging is guaranteed by high quantum efficiency and very good contrast resolution with optimized dosing even for women with dense glandular tissue. However, digital mammography remains a projection procedure by which overlapping tissue limits the detectability of subtle alterations. Tomosynthesis is a procedure developed from digital mammography for slice examination of breasts which eliminates the effects of overlapping tissue and allows 3D imaging of breasts. A curved movement of the X-ray tube during scanning allows the acquisition of many 2D images from different angles. Subseqently, reconstruction algorithms employing a shift and add method im...
