PURPOSE To compare rotational angiography with conventional digital subtraction angiography in the assessment of cerebral aneurysms. METHODS Conventional digital subtraction angiography and rotational angiography were compared in 57 patients investigated for the preoperative diagnosis of subarachnoid hemorrhage and in 13 patients after surgery. Images were compared for location, visibility of...

INTRODUCTION Erectile Dysfunction is a highly prevalent disease and there is growing interest in its endovascular treatment. Due to the complexity of the male pelvic arterial system, thorough anatomical knowledge is paramount. We evaluated the applicability of the Yamaki classification with Computerized Tomography Angiography and Digital Subtraction Angiography in the evaluation of patients wit...

The criterion standard for the detection of intracranial aneurysms is digital subtraction angiography. MR imaging and CT provide good accuracy in the evaluation of brain arteries and aneurysms. We herein report a case of a ruptured aneurysm at a basilar artery fenestration. The diagnosis was assessed with 16-row multisection CT angiography and was confirmed by using digital subtraction angiogra...

Digital subtraction angiography, whether based on traditional X-ray or MR, su ers from patient motion artifacts. Until now, the usual remedy is to pixel shift by hand, or in some cases performing a global pixel shift semi-automatically. This is time consuming, and cannot handle rotations or local varying deformations over the image. We have developed a fully automatic algorithm that provides fo...
