To investigate motion artifacts, image quality, and practical differences in electrocardiographic (ECG)-gated versus non-ECGgated high-pitch dual-source computed tomography angiography (CTA) of the whole aorta. Read more

Improved Delineation of Pulmonary Embolism and Venous Thrombosis Through Frequency Selective Nonlinear Blending in CT

posted by | Jul 20, 2017

The aim of this study was to test the hypothesis that a novel frequency selective nonlinear blending (NLB) algorithm increases the delineation of pulmonary embolism and venous thrombosis in portal-venous phase whole-body staging computed tomography (CT). Read more

A 64-year-old male patient with a known history of diabetes mellitus (DM) was feeling systemically unwell and noted problems with his left foot. He was presented for a CT angiography (CTA) evaluation. Read more

Case: Discovery of a Type II Endoleak after EVAR in a Patient with Renal Insufficiency using Dynamic 4D CT Angiography

posted by editors | Jun 10, 2016 editors

A 72-year-old male patient with poor kidney function (GFR 40 mL/min) was admitted to the hospital with a suspected endoleak after an endovascular aneurysm repair (EVAR) of the abdominal aorta. A dynamic 4D CT angiography (CTA) was requested to confirm the endoleak and to specify its type. Read more

  • 2015-12-09_tabelle_3

A 70-year-old female patient was referred to our emergency department complaining about a new onset of back pain and malignant hypertension. The initially performed CTA, on a 16-slice single source CT with 100 mL contrast media, revealed a Stanford B dissection. The patient was again referred to our department for … Read more
