[Specific characteristics of chest X‑ray in childhood : Basics for radiologists]. Radiologe. 2018 Mar 19;: Authors: Schneider K Abstract The radiographic technique of pediatric chest X‑rays is substantially different from that in adults. In nearly all cases ap/pa X‑rays are sufficient and lateral radiographs are rarely needed. In the first years of life the thymus may overshadow the heart, the great vessels and the lung hila. The most important anatomical structures essential for diagnosing pathological findings of the lungs and mediastinum are the trachea with the bifurcation and the main bronc...

[Inflammatory changes of the foot].
Abstract BACKGROUND: Inflammatory changes of the foot are comparatively rare and can be a challenge for radiologists with respect to the differential diagnosis, especially in cases with pre-existing degenerative changes of the foot skeleton. Comprehensive anamnesis and the use of contrast-enhanced MRI diagnostics are therefore often essential for diagnosis. OBJECTIVES: This review provides a cursory overview of the morphological characteristics of inflammatory changes of the foot and their differential diagnoses with a focus on osteomyelitis, joint infections, rheumatological diseases and tenosynovi...

Abstract BACKGROUND: Inflammatory bowel disease is a complex and challenging disease. In diagnosis and the course of disease both radiology and endoscopy play a vital role. OBJECTIVES: The purpose of this review is to provide an overview of the questions asked by the clinician. Depending on the situation (clinical presentation of the patient, laboratory results) these questions can vary considerably and should be answered using the most appropriate imaging technique. Therefore, in the authors' view, a close cooperation between the clinician and the radiologist is imperative to provide optimal c...

AO Abstract During the past 30 years, classifications and scoring systems have been developed in order to evaluate and objectify the degree and activity of anorectal fistulas. Only a few of these disease-specific instruments have been adopted into daily clinical routine. Generally, clinicians tend to use global medical judgement rather than numeric activity indices, which often seem complex and time consuming. Activity scores in Crohn disease, however, appeared to be very useful in clinical trials regarding evaluation of therapy response. Thus, activity indices must be simple and reproducible. The years...

Abstract CLINICAL/METHODICAL ISSUE: Due to mechanical loading and the number of joints involved, fractures of the foot are among the most common fractures.

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...

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...

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...
