Standardized Reporting of Prostate MRI: Comparison of the Prostate Imaging Reporting and Data System (PI-RADS) Version 1 and Version 2.

Introduction: Objective of our study was to determine the agreement between version 1 (v1) and v2 of the Prostate Imaging Reporting and Data System (PI-RADS) for evaluation of multiparametric prostate MRI (mpMRI) and to compare their diagnostic accuracy, their inter-observer agreement and practicability.

Material And Methods: mpMRI including T2-weighted imaging, diffusion-weighted imaging (DWI) and dynamic contrast-enhanced imaging (DCE) of 54 consecutive patients, who subsequently underwent MRI-guided in-bore biopsy were re-analyzed according to PI-RADS v1 and v2 by two independent readers. Diagnostic accuracy for detection of prostate cancer (PCa) was assessed using ROC-curve analysis.

[Infrarenal abdominal aortic aneurysm: endovascular repair with stent grafts].

As an alternative to surgery, endovascular therapy with stent grafts has become the second main treatment option for infrarenal abdominal aortic aneurysms. Unlike surgery, endovascular treatment with stent grafts is also applicable in patients unfit for open repair. Despite current improvements in endovascular repair devices, significant anatomic barriers still exclude this technique for a large number of patients.

[Embolotherapy: principles and indications].

Vascular embolizations are complex and sophisticated procedures and can be a powerful alternative or useful adjunct to surgery in many clinical situations. Hemorrhage, vascular malformations, and tumors are the main indications for embolization procedures. Establishing the correct indication for intervention as well as the proper embolic agent and the most suitable catheterization technique requires advanced knowledge in interventional radiology, and an interdisciplinary approach is a prerequisite.

Hemobahn stent-grafts for treatment of femoropopliteal arterial obstructions: midterm results of a prospective trial.

Purpose: To report a prospective study to evaluate safety, effectiveness, and midterm patency of self-expanding stent-grafts in patients with femoropopliteal occlusive disease.

Materials And Methods: Sixty-three Hemobahn stent-grafts were used in 52 patients for treatment of medium- or long-segment (>3 cm) occlusions (82.7%) and stenoses (17.

Results of a European multicentre iliac stent trial with a flexible balloon expandable stent.

Purpose: to determine the 12 months success rate with a balloon expandable, flexible stainless steel stent in iliac artery obstructions.

Materials And Methods: one-hundred and twenty-six consecutive patients with iliac obstructive disease and who demonstrated an unsatisfactory angioplasty result with a post-dilatation gradient of at least 10 mmHg, or a primary occluded lesion were included in the study. Follow-up was by Doppler sonography, ankle pressures with and without exercise and clinical parameters.
