The purpose of our retrospective study was to determine the feasibility and efficacy of the endovascular embolization of peripheral acute arterial hemorrhage using Onyx. ⋯ We conclude that transcatheter embolization with the new liquid embolic agent Onyx is technically feasible and effective in patients with acute arterial hemorrhage.

Approximately 4000 volunteers will undergo whole-body magnetic resonance imaging (WB-MRI) within the next 3 years in the population-based Study of Health in Pomerania (SHIP). Here we present a pilot study conducted (a) to determine the feasibility of adding a WB-MRI protocol to a large-scale population-based study, (b) to evaluate the reliability of standardized MRI interpretation, and (c) to establish an approach for handling pathological findings. ⋯ The preliminary results presented here indicate that a large prospective, population-based study using WB-MRI is feasible and that the results of image analysis are reproducible. A variety of positive findings provide valuable information regarding disease prevalence in a general adult population.

Comparative Study Controlled Clinical Trial
[First experiences with intravenous port systems authorized for high pressure injection of contrast agent in multiphasic computed tomography].
The aim of this prospective study was to examine two port systems for intravenous chemotherapy, authorized for high pressure injection, with respect to implantation, complications, implementation, and patency. ⋯ The intravenous high pressure port systems are equivalent to standard systems with regard to implantation and implementation. Intravenous chemotherapy can be performed as usual. The advantage is the possibility of multiphasic CT with authorized flow rates of up to 5 ml/sec.

Microvascular obstruction (MO) and the extent of infarction are important prognostic factors in acute myocardial infarction. Our study aimed to investigate the effect of the time interval between contrast administration and image acquisition on the quantification of microvascular obstruction and myocardial infarction. ⋯ Our study shows that the time delay between contrast media injection and image acquisition has a significant impact on the delimitable extent of MO and infarct size.
