Abstract:
The analysis of sensitivity and specificity of magnetic resonance angiography (MRA) was performed in investigation of vertebral and basilar arteries in 29 patients with acute vertebrobasilar insufficiency. MRA data were compared with the results of ultrasonic dopplerography of the same vessels including duplex scanning and figures subtractive angiography. Highly satisfactory efficiency of MRA was demonstrated. Peculiarities of both visualization of the intact vessels and of different variations of their obstruction as well as indications for performing diagnostic MRA are considered.
