The Ductus Venosus.

Background:  the ductus venosus (DV) is not well known in general radiology, but it plays a role in the daily work of pediatric radiologists. Consequently all general radiologists who also care for a pediatric department should be familiar with the physiological and pathological findings related to the DV.

Methods: Literature research in Medline, using the keywords "ductus venosus" and "umbilical vein catheter".

The German Evidence-Based Child Protection Guideline - Imaging in Suspected Child Abuse.

Aim:  Development of a fully evidence-based guideline including all aspects of child abuse.

Methods:  In a case-based procedure, 144 primary PICO questions were generated from 476 presented cases of child abuse. Literature research was performed in 5 databases (Pubmed, CINHAL, Embase, PsycInfo, Eric) and in the Cochrane Library.

Sensitivity encoding (SENSE) for contrast-enhanced 3D MR angiography of the abdominal arteries.

Purpose: To assess sensitivity encoding (SENSE) for contrast-enhanced MR angiography (CE-MRA) of the abdominal arteries in comparison with standard MRA protocols.

Materials And Methods: In 22 patients MRA of the abdominal arteries was performed twice (once using a standard protocol, and once with the additional use of SENSE). In 10 patients all examination parameters were kept constant (TR/TE/FA = 3.

Noninvasive detection of steno-occlusive disease of the supra-aortic arteries with three-dimensional contrast-enhanced magnetic resonance angiography: a prospective, intra-individual comparative analysis with digital subtraction angiography.

Background And Purpose: Concomitant disease of the supra-aortic arteries can influence the outcome of surgical treatment of carotid artery stenosis. However, sensitivity and specificity data of noninvasive contrast-enhanced 3-dimensional (3D) magnetic resonance angiography (CE MRA) for the detection of steno-occlusive disease of the entire supra-aortic arteries including the circle of Willis remain unclear. We aimed to intra-individually compare high-spatial-resolution CE 3D MRA and digital subtraction angiography (DSA) for the assessment of steno-occlusive vascular disease of the supra-aortic arteries.

Time-of-flight MR angiography: comparison of 3.0-T imaging and 1.5-T imaging--initial experience.

Intracranial three-dimensional time-of-flight (TOF) magnetic resonance (MR) angiography was performed in seven healthy volunteers and eight patients with both 1.5-T and 3.0-T MR systems with standard and high spatial resolutions (true voxel sizes, 0.
