A case is reported of a patient with the subclavian steal syndrome in whom the reversed blood flow of the vertebral artery was shown by phase encoded magnetic resonance angiography.

A 51-year-old man with hypertension had previously been admitted to our cardiothoracic unit with a type A aortic dissection (Stanford classification) and had undergone emergency surgery with partial replacement of the ascending aorta. Routine follow-up magnetic resonance angiography (MRA) 19 months after the operation revealed an aneurysm at the incision site in the ascending aorta and extensio...

When interpreting and analysing magnetic resonance angiography images, the 3D overall tree structure and the thickness of the blood vessels are of interest. This shape information may be easier to obtain from the skeleton of the blood vessels. Skeletonization of digital volume objects denotes either reduction to a 2D structure consisting of 3D surfaces and curves, or reduction to a 1D structure...

Magnetic resonance (MR) angiography as a method for the long-term follow-up of cerebral arteriovenous malformations (AVMs) was assessed in 14 patients with cerebral AVMs. These patients were either untreated or treated with transarterial embolization and/or stereotactic radiosurgery (gamma knife). Two-dimensional- and three-dimensional (3D)-time-of-flight (TOF) techniques were useful for follow...

Angiography Carotid Arteries To the Editor: We were very interested to read the recent study by Johnston et al1 regarding the use of contrast-enhanced MRA (CEMRA) for carotid stenosis. The authors correctly highlight in their introduction the limitations of many current studies of noninvasive tests. We, however, remain to be convinced that their own study is an adequate reflection of the perfor...
