[Spinal cysts : Diagnostic workup and therapy].
Abstract CLINICAL ISSUE: Spinal cysts can be classified as meningeal, not meningeal, and tumor-associated cysts. Due to the widespread availability of high-resolution computed tomography and magnet resonance imaging, spinal cysts can be detected with high sensitivity these days. Concerning the variety of potential cystic differential diagnoses, a precise classification is difficult and can often only be realized after surgical inspection or histological examination. PRACTICAL RECOMMENDATIONS: Spinal cysts are generally incidental findings during a routine diagnostic workup and need no further therapy. Su...

Radiologe. 2018 Jan 29;: Authors: Beuthien-Baumann B Abstract CLINICAL/METHODICAL ISSUE: Magnet resonance imaging (MRI) is an excellent anatomical reference method for the combination with positron emission tomography (PET). But MRI does not produce data, which can be directly used for attenuation correction of PET data, potentially compromising quantitative accuracy of PET. STANDARD RADIOLOGICAL METHODS: Hybrid-positron emission tomography/computed tomography (PET/CT) is an established standard diagnostic tool, particularly for staging and restaging in oncology. Attenuation correction...

[Importance of Virchow-Robin spaces].
nn A Abstract Virchow-Robin spaces are perivascular fluid-filled cavities that surround perforating arteries and veins in the brain parenchyma. As a rule in healthy people they are approximately 5 mm in diameter. Typical localizations are brainstem ganglia, mesencephalon and the white matter of the brain. Morphological imaging characteristics of Virchow-Robin spaces are round or tubular, smoothly bordered areas which are hyperintense in T2-weighted sequences. Virchow-Robin spaces represent a physiological structure in normal brain parenchyma. It is assumed that they contain interstitial fluid filled with macr...

Abstract Distal radius fractures are associated with high individual and socioeconomic relevance. Optimized radiography and computed tomography (CT) imaging are essential for individualized therapy planning. Plain CT imaging with 3D reconstruction and digital removal of the carpus and ulna is helpful for choosing the surgical approach in the presence of intra-articular radius fractures. If the fracture line leads towards the scapholunate compartment, ligamentous injury requiring treatment can be detected or ruled out before surgery with the help of direct CT arthrography (CTA). Acquisition of imaging data and morp...

As the clinical relevance of oligometastatic disease in primary cancer detected by PSMA PET-CT imaging is not yet completely understood, it should only be used in clinical trials. In recurrent prostate cancer after therapy with curative intent, PSMA PET-CT shows encouraging potential for the planning of salvage therapy. In metastatic castration-resi...

Abstract Soft tissue tumors represent a special challenge in interdisciplinary cooperation. Malignant tumors require a multimodal therapy concept so that patient treatment in a specialized tumor center is recommended. The task of the surgeon in close cooperation with the radiologist is the resection of the tumor in sano with the required safety margin. The aim of diagnostic imaging is to describe the primary expansion of the tumor size and a possible tumor infiltration of adjacent compartments. The most important diagnostic imaging for this purpose is magnetic resonance imaging (MRI), especiall...

[Relevance and therapy of intracranial arachnoidal cysts].
Abstract Intracranial arachnoidal cysts (AC) are relevant due to their space-demanding character. The pathophysiological sequelae are dependent on the size and location of the cyst and the patient's age. Direct pressure on surrounding tissue causes headaches (meninges) or rarely seizures (brain tissue). Cerebrospinal fluid (CSF) circulation disturbances resulting from brain mass displacement with occlusion of, for example, the foramen monroi or the aqueduct cause occlusive hydrocephalus, which can lead to an increase in intracranial pressure. Depending on age, the typical primary clinical symptoms or findings diff...

Abstract Mesenchymal tumors in childhood comprise benign and malign entities and differ regarding typical sites of manifestation, age peak and clinical symptoms. In some cases biopsy is mandatory. If nephroblastoma is a possible diagnosis, biopsy must be avoided by all means in order to avoid biopsy tract metastasis. Imaging is used to narrow the differential diagnosis, describe the exact extent of the lesion and deliver complete staging. In pediatric patients sonography and MRI are the most important imaging modalities. Low-dose CT of the thorax serves for assessment of possible pulmonary metastases. PMID: 2...

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...
