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

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
