BACKGROUND AND PURPOSE Carotid endarterectomy has been shown to be beneficial in symptomatic patients with a severe stenosis (70% to 99%) of the internal carotid artery (ICA). Digital subtraction angiography (DSA) is the standard of reference in the diagnosis of carotid artery stenosis but has a relatively high complication rate. In a diagnostic study we(More)
PURPOSE To evaluate whether and to what extent greater number of projection images obtained at three-dimensional (3D) time-of-flight (TOF) magnetic resonance (MR) angiography versus conventional digital subtraction angiography (DSA) causes overestimation of internal carotid arterial (ICA) stenosis. MATERIALS AND METHODS DSA (two or three projections),(More)
PURPOSE To assess how often rotational angiography depicts more severe internal carotid arterial stenosis compared with conventional intraarterial digital subtraction angiography (DSA) in two or three projections and how frequently this factor may affect patient treatment. MATERIALS AND METHODS Rotational angiography (16 or 32 projections) was performed(More)
AIM To evaluate the impact of selective imaging on clinical management of patients who present with symptoms suggesting acute appendicitis. MATERIALS AND METHODS During a two-and-half year period, 941 consecutive patients with right lower quadrant pain were analyzed. Patients who underwent selective imaging were compared to those treated without further(More)
Diagnosing pulmonary embolism (PE) is a challenge for many physicians as it is a frequently occurring disease with nonspecific symptoms and signs. Ventilation-perfusion (V/Q) scintigraphy is widely used as the first step in diagnosing PE since it is non-invasive and highly sensitive. With a normal perfusion scan, clinically relevant pulmonary thrombo-emboli(More)
BACKGROUND Percutaneous thrombolysis has become an accepted treatment of thrombosed haemodialysis grafts. Several devices have been developed for mechanical thrombolysis, which macerate the clot using different mechanisms such as aspiration and fragmentation. The aim of our study was to compare the efficacy of three devices for mechanical thrombolysis in(More)
BACKGROUND AND AIMS The purpose of this study was to determine the accuracy, interobserver variability, timing and discordance with relaparotomy of postoperative radiological examination of colorectal anastomoses. PATIENT/METHODS From 2000 to 2005, 429 patients underwent an ileocolonic, colo-colonic, or colorectal anastomosis. Radiological examination of(More)
