[Magnetic resonance angiography of stents].

Purpose: To understand the behavior of stents during contrast-enhanced magnetic resonance angiography (MRA).

Materials And Methods: Seven different types of stents are explored in vitro with spin echo (SE) T2 sequence and MRA sequences using classification of the intra-prothesis signal. Six patients with 11 different proximal stents are studied by Gadolinium enhanced MRA with the same classification.

[Study of atheromatous stenoses of carotid bifurcations by Doppler ultrasound, spiral angio-MRI, magnetic resonance angiography and comparison with arteriography].

Purpose: To evaluate Doppler ultrasound (US), Helical CT, Magnetic Resonance (MR) angiography in the detection of carotid bifurcation atherosclerotic disease and comparison with angiography.

Materials And Methods: After a Doppler US procedure, 56 carotid bifurcations were included (symptomatic stenosis greater than 60% or asymptomatic stenosis greater than 30%). Helical CT, MR angiography and selective arteriography were performed.

[The development of public health education: the Mauritius experience].

A public course has been initiated in 1990 in Mauritius for covering the national growing needs of public health specialists. This training course was organized jointly by the Ministry of Health, the University of Bordeaux II and the French Cooperation. After 3 sessions dedicated specifically to the Mauritian physicians, the course has been re-designed for the needs of the other countries of the region.
