CT examination in aorta totalis protocol. Dose was around 1.1mSv and also because of the high pitch mode, contrast media material was saved. Read more

At sub-second, low radiation dose CTA of the chest, use of individualized, patient-based contrast media delivery protocols results in reliable, diagnostic contrast enhancement of all target vessels. Read more

The objective of this study was to evaluate the feasibility and efficiency of this technique by comparing maximum intensity projections (MIP) created with different bone removal techniques. Read more

Case history 81-year-old male presented for follow-up exam to indicate convalescence progress. 6 weeks before, he had been delivered for coiling and stent implantation due to ruptured aneurysm. He had complained about pain in the lower abdominal region. A day after the stent implantation a type II endoleakage had appeared. 4 … Read more

Objective: In supraaortic vessels, bone subtracted maximum intensity projections make the evaluation of computed tomographic angiography (CTA) datasets easier and faster. Dual energy CT can be used for bone removal without user interaction. The purpose of this study was to compare the results of conventional and dual energy-based bone removal. Materials … Read more

Purpose: To assess the diagnostic performance of dual-energy dual-source computed tomography (CT) in the detection of endoleaks after endovascular abdominal aortic aneurysm (AAA) repair. Materials and Methods: This study was local ethics board approved, and written informed consent was obtained from all patients. One hundred eighteen patients (21 women, 97 men; mean age, … Read more

The following abstract was presented during the 89th German Congress of Roentgenology in Berlin (May 2008, 20th – 23th) Purpose: Dual energy CT allows automatic removal of calcified plaques from vessel lumen based on different absorption properties of calcium and iodine. The purpose of this phantom study was to evaluate the … Read more
