Diagnostic Reference Levels for nuclear medicine imaging in Austria: A nationwide survey of used dose levels for adult patients.

Purpose: To assess dose levels in routine nuclear medicine (NUC) procedures in Austria as a prior to a legislative update of the National Diagnostic Reference Levels (NDRL).

Method: As part of a nationwide survey of common NUC-examinations between June 2019 and November 2019, data sets were collected from 33 Austrian hospitals with NUC equipment. All hospitals were asked to report the NUC imaging devices in use (model, type, year of manufacture, detector material, collimators), the standard protocol parameters for selected examinations (standard activity, collimator, average acquisition time, reconstruction type, use of time-of-flight) and to report data from 10 representative examinations (e.

[Inflammatory gastrointestinal diseases in children : Radiological diagnosis].

Background/clinical Issue: Inflammatory bowel diseases are frequently seen in the clinical routine of a pediatric radiologist. The timely diagnosis of inflammatory bowel diseases in children is particularly important in acute cases.

Standard Radiological Methods/methodological Innovations: This nonsystematic article intends to give an overview of the radiologic imaging methods for the diagnosis and work-up of pediatric patients with inflammatory bowel diseases.

Fine-Needle Aspiration with Immunohistochemistry Using a Modified Scrape Cell Block Technique for the Diagnosis of Thyroid and Parathyroid Nodules.

Objective: To evaluate the diagnostic accuracy of a modified scrape cell block (SCB) technique in a large series of patients. The technique was especially developed and tested for fine-needle aspiration of thyroid and parathyroid nodules.

Study Design: Eighty-two ultrasound-guided fine-needle aspiration specimens with the sonographic aspect of a thyroid (n = 33) or a possible parathyroid nodule (n = 49) were studied.

FDG PET and FDG PET/CT in patients with gastrointestinal stromal tumours.

Gastrointestinal stromal tumours (GISTs) are fairly rare neoplasms, constituting less than 3 % of all gastrointestinal malignancies. The integration of molecularly targeted treatment regimes (i.e.
