[Dynamic evaluation of lower limb arteries using the ECTRICKS MRI technique]. / La perspective d'une étude dynamique des artères des membres inférieurs en IRM grâce à la séquence ECTRICKS.

ABSTRACT

PURPOSE: This article presents a new MR angiography technique, Elliptic Centric Time Resolved Imaging on Contrast KineticS (ECTRICKS), which allows dynamic evaluation of the lower limb arteries opacification when venous return prevents adequate diagnostic evaluation of calf arteries. PATIENTS AND METHODS: Comparative examinations could be compared. Additional arteries in 59 patients using a standard MRA technique and the ECTRICKS technique. RESULTS: A total of 33 examinations could be compared. Additional arteries could be evaluated in 10% of our patient population using the ECTRICKS technique, and in 20% for our diabetic population. Arterial evaluation was better with the ECTRICKS technique in patients with diabetes and venous insufficiency. CONCLUSION: ECTRICKS is a good complementary sequence for evaluation the calf arteries in patients with diabetes or early venous return.
