ABSTRACT
During different studies on 1.5 Tasla equipments it was possible to obtain proper images with different values for different parts of limb. To date no research of such kind has been done in Iran and angiography of lower limbs is not done at present. In this study, it was tried to proper images of lower limbs considering the capabilities of designed protocol system.1.5 Tasla MRI equipment with optimized parameters for different positions calculated on the volunteers, patients and phantom was used. SNR and CNR images were compared, and categorized by radiologist based on diagnostic values. First stage of recovery current, a lower, mobile pre saturated pulses, NSA=1, matrix size 128 to 180 at direct phase and 256 direct frequency were selected. The qualitative value of the images 3 at pelvis area; 3 at femoral and knee areas; and 4 for knee was obtained. Total time required for imaging of lower limb was 45 minutes. This technique is useful particularly for the patients who can not go under conventional angiography. The value of the MR images using contrast drug is higher than the images obtained by this method, however this method is cheaper.
