A case of acute rupture of an abdominal aortic aneurysm in a patient with Behçet's disease is reported. The patient was successfully treated by implantation of an endovascular stent graft. The preinterventional diagnostic procedures and the postinterventional follow-up are described and the benefit and risk vs open surgery is discussed.
In modern magnetic resonance imaging (MRI) gradient echo (GE) sequences have been shown to be superior to conventional spin echo (SE) sequences in characterising renal masses and staging renal tumours. In this study MRI was carried out in patients with renal masses (n = 97, histologically proven n = 43) using a fast GE-sequence (multislice technique, TR/TE 80/5 ms) and an i.v. bolus application of gadolinium (Gd)-DTPA mostly in axial, in selected cases additionally in coronal slice orientation. MRI findings were compared with those of contrast-enhanced CT (n = 56). The results demonstrated that MRI under Gd-DTPA has a reliably good image quality and can characterise renal masses safely. Compared with CT in multislice MRI problems of partial volume effects can be reduced; complex renal cysts can be differentiated more safely from solid tumours with unclear CT findings due to a significantly higher contrast enhancement in MRI.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
