چکیده

results 22 patients were male (73.3%) and the mean age was 60.3 ± 10.6 years in our study group. the most common artery for cut off and run off was superior femoral artery in both assessments. proximal section of each artery was the most common anatomical section for cut off and run off. there was a same report of cut off artery by mr-angiography and surgery (kappa coefficient of agreement was 0.96, p value < 0.001) and positive predictive value was 0.97 (95% ci: 0.83-0.99). conclusions according to our findings mr-angiography is an appropriate alternative imaging modality for patients suspected to have peripheral arterial disease and it facilitates the early diagnosis proposed by the clinical findings. also beneficial characteristics of this method such as low exposure to ionizing radiation, repeatability, and low risk of contrast agent-induced nephropathy make it a modality of choice in patients with renal impairment. objectives to compare the results of gadolinium enhanced mr-angiography and surgery in patients suspected to have peripheral arterial disease. materials and methods in this prospective cohort study, 30 consecutive patients matching the inclusion criteria were enrolled and mr-angiography was performed prior to surgery for each one. background peripheral arterial disease (pad) represents systematic atherosclerosis of great vessels. pad affects approximately 10-20 % of patients older than 60 years and is associated with high mortality and morbidity rate debilitating individuals’ life.
