[Pediatric brain tumors].
s R Abstract Brain tumors differ between children and adults both in histology and localization. Malignant gliomas and meningiomas predominate in adults while medulloblastomas and low-grade astrocytomas are the most frequent brain tumors in children. More than one half (50-70%) of pediatric brain tumors have an infratentorial location but only approximately 30% in adults. Brain tumors can be recognized in sonography, cranial computed tomography (CCT) and magnetic resonance imaging (MRI) by their space-consuming character and by their divergent density and intensity in comparison to normal brain parenchyma. They ca...

[Adverse effects of immunotherapy : Clinical aspects, radiological and nuclear medicine results].
CONCLUSION: Knowledge of clinical and imaging findings of adverse events induced by immunotherapy is essential for timely and adequate therapeutic decisions. In addition to staging and follow-up imaging, identification and monitoring of immune-related adverse events adds to the radiologic responsibility in oncologic care.

[Tumors of the sellar region].
Abstract METHODICAL ISSUE: The anatomy of the sellar region is complex and tumors of the sellar region are very variable because they arise from the many different tissue types in the sellar region, ranging from benign to life-threatening. Despite this variety, approximately 80% of sellar region tumors are due to the 5 most common lesions: adenomas, meningiomas, aneurysms, astrocytomas and craniopharyngiomas. STANDARD RADIOLOGICAL METHODS: In addition to clinical and laboratory results, the magnetic resonance imaging (MRI) and computed tomography (CT) results including the exact anatomical position and the pr...

[Interventional treatment of benign prostatic hyperplasia : Embolization of the testicular vein].
Abstract CLINICAL/METHODICAL ISSUE: Embolization of the testicular veins (Gat-Goren technique) is an interventional procedure for the treatment of benign prostatic hyperplasia (BPH). STANDARD RADIOLOGICAL METHODS: In addition to standard urological procedures, such as transurethral resection of the prostate (TUR-P), arterial embolization of the prostate is considered as the interventional radiological method of choice. METHODICAL INNOVATIONS: Embolization of the testicular veins is technically identical to the embolization of varicoceles in infertile men and represents a less invasive treatment. ...

[Radiation protection in medical research : Licensing requirement for the use of radiation and advice for the application procedure].
DISCUSSION: The qualified physicians involved in a study are responsible for deciding whether a license is required for the intended application of radiation. The decision can be guided by answering the key question whether the study participants would undergo the same exposures regarding type and extent if they had not taken part in the study. When physicians are still unsure about their decision, they can seek the advisory service provided by the professional medical societies. Certain groups of people are particularly protected through the prohibition or restriction of radiation exposure. A simplified lic...

[Value of cardiac CT in the diagnostic work-up of coronary artery disease : Update 2017].
Abstract The quantification of coronary calcifications using noncontrast-enhanced computed tomography (CT) as well as coronary CT angiography (cCTA) have rapidly evolved in the recent years. Nowadays, both techniques are increasingly clinically accepted regarding risk stratification and accurate exclusion of significant coronary artery disease (CAD). The higher acceptance of cCTA is mainly based on the higher robustness, lower radiation exposure through continuous technical innovations as well as by the growing scientific evidence. The poor predictive value of cCTA for predicting the hemodynamic significance of de...

Abstract The occurrence of a stroke in children and adolescents constitutes a rare, critical event that is associated with substantial morbidity and mortality. In addition to the individual suffering for the young patient and the medical burden for the affected family, a stroke is also associated with high follow-up costs for the health system because of the necessary long-term rehabilitative treatment. Establishing an early and prompt diagnosis is of great therapeutic importance. Because of the rarity of the illness and the plethora of clinical manifestations, diagnosis is often delayed. The most freque...

Most carcinoids arise from the central airways and only a minority of carcinoids are found in the lung periphery. While most of the peripheral carcinoids are asymptomatic, central carcinoids are symptomatic and present with hemoptysis, wheezing or bronchial obstruction. On computed tomography (CT), carcinoids frequently present as hypervascular pulmo...

Various factors (R) influencing the clinical manifestation of radiation effects have been identified related to the exposure pattern. The radiation tolerance of normal tissue structures regarding the induction of functional deficits shows great variation but always has a threshold value, which is usually not exceeded in diagnostic procedures.
