BACKGROUND Mapping of the great saphenous vein is very important for planning of peripheral and coronary bypass surgery. This study investigated mapping of the great saphenous vein as an adjunct to peripheral MR angiography using a blood pool contrast agent in patients who were referred for evaluation of peripheral arterial occlusive disease and bypass surgery. METHODS 38 patients with periph...

Nature of the scan Generally, a follow-up scan after a carotid stenting procedure is performed for the surveillance of the stent, not for monitoring of the untreated contralateral carotid. Hence, if the contralateral artery is not significantly stenosed, we perform ipsilateral scans only (i.e. “targeted US”). Since the distal/cephalic end of the carotid stent can be placed well distal/cephalic ...

Kazutoshi Fujita, MD Toshihiro Fujiwara, MD, PhD Masao Kakibuchi, MD, PhD Department of Plastic Surgery Hyogo College of Medicine Hyogo, Japan Sir: T use of computer tomography angiography (CTA) is combined with ultrasound duplex scanning to identify perforating arteries preoperatively for abdominal free flap breast reconstruction.1 CTA shows the course of the blood vessels on the computer’s di...

BACKGROUND AND PURPOSE The correct detection and quantification of carotid artery disease are of decisive impact on patient prognosis and adequate treatment. In this study, we evaluated the ability of ultrasonography to detect and to grade carotid artery stenosis through a comparison of the in vivo ultrasound findings with the planimetric analysis of the corresponding postmortem specimens. ME...

Chronic cerebrospinal venous insufficiency (CCSVI) is a syndrome characterized by stenoses or obstructions of the internal jugular and/or azygos veins with disturbed flow and formation of collateral venous channels. Studies using ultrasound in patients with multiple sclerosis (MS) have demonstrated a high prevalence of CCSVI (mean 70%; range 0-100%; N.=1496), whereas, in normal controls and pat...

Prenatal ultrasound is a powerful diagnostic tool, but there has been little research on how to teach ultrasound to family physicians. The available evidence supports teaching through didactics followed by supervised scanning. Didactic topics include physics and machine usage, indications, fetal biometry, anatomic survey, practice management, ethical issues, and resources. Supervised scanning r...
