[Ultrasound of muscular diseases in children and adolescents].
We present their differential diagnosis by texture and echogenicity analysis. Affected persons are identified in 70% up to 100% of cases, depending on the entity; specificity is less dependent on experience and training. Of the 12 disorders presented in this article, 6 are causally/symptomatically treatable today. ACHIEVEMENTS: Standardized myosonography is the imaging modality of first choice for detection of neuromuscular diseases. PRACTICAL RECOMMENDATIONS: High frequency (8-22 MHz) linear array transducer. Highly standardized examination modality. Simultaneous, paired comparison of affected p...

[Inflammatory muscle diseases (myositis)].
Abstract CLINICAL ISSUE: Inflammatory muscle diseases are quite heterogeneous and frequently a specific diagnosis is not easy. STANDARD RADIOLOGICAL METHODS: Magnetic resonance imaging (MRI) is best suited to demonstrate pattern and size of inflamed muscles. PERFORMANCE: Sensitivity of MRI in showing inflamed muscles is nearly 100%. Specificity, however, is much lower. PRACTICAL RECOMMENDATIONS: In cases of suspected bacterial myositis, sonography may be used to exclude abscess formation prior to MRI for more precise information about inflamed muscles.

Abstract Benign, intermediate and malignant soft tissue tumors can be differentiated histologically. Furthermore, the tumors can be subdivided according to their linear differentiation. In the new World Health Organization (WHO) classification of soft tissue tumors from 2013 changes have been made relating to the allocation of known entities, e. g. undifferentiated sarcomas have been formed into a new subgroup and are no longer assigned to the fibrohistiocytic tumors. The term malignant fibrous histiocytoma has been replaced by the undifferentiated sarcoma. Furthermore, two new subgroups were incorpora...

Abstract CLINICAL ISSUE: Neurogenic myopathies are primary diseases of the nervous system, which secondarily result in denervation of the target musculature. The spectrum of potential causes is manifold ranging from acute traumatic injuries and chronic compression to neurodegenerative, inflammatory, metabolic and neoplastic processes. STANDARD DIAGNOSTIC METHODS: The medical history, clinical neurological examination, and electrophysiological tests including electromyography and nerve conduction studies are crucial in diagnosing neuropathic myopathies. Electromyography is the gold standard for diagnosing musc...

Abstract Even primary diagnostic evaluation of the shoulder is a challenge for radiologists. Many imaging findings that definitely indicate abnormal findings in the untreated shoulder should be evaluated carefully in postoperative patients. Artifacts caused by implants or metal abrasion pose considerable problems in postoperative magnetic resonance imaging (MRI). Classic approaches to minimizing artifacts caused by foreign bodies include using turbo spin echo sequences, increasing bandwidth, and reducing voxel size. In recent years, several vendors have developed dedicated pulse sequences for reducing metal a...

[Imaging of primary muscular diseases : What do neurologists expect from radiologists?]
Abstract Imaging, in particular magnetic resonance imaging (MRI), has in recent years increasingly become a crucial tool for the diagnostics of inherited and acquired muscular diseases. The aim of imaging in neuromuscular disorders goes beyond the detection and quantification of degenerative muscular changes, such as fatty degeneration and includes recognition of very early signs of muscular pathologies presenting as muscular edema. Therefore, imaging is a valuable diagnostic method to support the clinical diagnosis and to narrow down the differential diagnoses, leading to specific additional diagnostic tests in o...

IM Abstract Posttreatment imaging of primary bone tumours represents a diagnostic challenge for radiologists. Depending on the primary bone tumour common radiological procedures, such as radiography, computed tomography (CT), and magnetic resonance imaging (MRI), are employed. Radiography and CT are particularly useful in benign bone tumours and in matrix-forming bone tumours. MRI comes into consideration with malignant tumour recurrence and tumoral soft tissue infiltration. Bone scintigraphy is of superior importance if a primarily multifocal manifestation of bone tumour or metastasizing tumour disease...

CURRENT SITUATION: Owing to poor remuneration and the large effort required, ultrasound is not a priority at many institutions, and compared to CT, MRI or interventions, little reward is given to those committed to ultrasound. Intense practical teaching is rarely given. As a result, residents have to teach themselves or gain experience during rotations outside radiology. In some cases, they are not educat...

This article provides an overview of the different cartilage repair procedures and important characteristics to look for in cartilage repair imaging. Specifics and pitfalls are pointed out alongside general aspects. After successful cartilage repair, a complete, but not hypertrophic filling of the defect is the primary criterion of treatment success. The repair tissue should also be completely integrated to the surrounding native cartilage. After some months, the transplants signal should be isointense compared to native cartilage.

In this study, we evaluated methods of quantification of tumor mass in whole-body MRI (wb-MRI) in multiple myeloma and correlated these with disease-related parameters in serum and bone marrow. MATERIALS AND METHODS: We retrospectively evaluated wb-MRIs of 52 patients with focal infiltration pattern and a total of 700 focal lesions (subsequently called lesions). We determined the longest diameter (LD), the segmented volume (SV), and the morphology (spherical or non-spherical). We correlated total number/volume of the lesions with clinical parameters and prognosis and furthermore LD with SV. After that we ana...

[Posttherapeutic changes in bone marrow].
Abstract The bone marrow basically consists of red blood-forming bone marrow and yellow fat. In the skeleton, there is an age-dependent distribution of these two parts. In the context of medical interventions or therapies, bone marrow changes can occur, whereby the normal bone marrow can basically be replaced by fat, edema, or fibrosis/sclerosis. Here, specific signal intensities and patterns are shown in imaging. After irradiation therapies, edematous changes, hemorrhages, and osteoradionecroses are observed. Likewise, insufficiency fractures, impairment of the growth gaps, or the development of tumors is possibl...

However, atypical response patterns of immunotherapies are not correctly classified using RECIST 1.1 so that the effectiveness is also incorrectly interpreted.

For this reason exact localization of these lesions is extremely important. Extra-axial tumors are the most common neoplasms among adults. They can be divided in a broad spectrum of histopathological subgroups. The most common extra-axial tumors are meningiomas, which arise from the dura mater. In the vast majority of cases they a...
