BACKGROUND Computed tomography Peripheral angiography (CTPA) and Non enhanced magnetic resonance angiography (NE-MRA) are accurate techniques for selecting patients with peripheral arterial disease for surgical and endovascular treatment. No studies in the literature have directly compared CTPA and NE-MRA to establish which one should be employed, in patients suitable for both techniques, before endovascular treatment. Objective- A Prospective study of 44 Patients was performed to compare the effectiveness of CTPA and NE-MRA in the evaluation of patients with peripheral vascular diseases. MATERIALS AND METHODS A prospective study was conducted over a period of twenty-three months (December 2016 to September 2018) on 44 patients with clinically suspected Peripheral Vascular Disease. They were evaluated with 128 Slice CT Scanner (PHILIPS INGENUITY) and1.5 Tesla MRI (PHILIPS - ACHIEVA). RESULTS The results of our study have shown that unenhanced MRA is a potential alternative or complementary modality to CTA for showing clinically significant arterial disease in patients with the peripheral arterial disease with symptomatic chronic lower limb ischemia. CONCLUSION CTA is a compulsion over NE-MRA in case if the patient is having absolute contraindications like cardiac pacemakers, aneurysmal clips, metallic implants, or undergone prior bypass stenting for peripheral arterial disease, and in case of emergency settings like trauma. NE-MRA is an alternate modality to CTA in case if the patient is having renal insufficiency, severe diabetes who may have calcified vessels and renal complications.
