TO COMPARE CT PERIPHERAL ANGIOGRAPHY AND NON ENHANCED MAGNETIC RESONANCE PERIPHERAL ANGIOGRAPHY IN EVALUATION OF PERIPHERAL VASCULAR DISEASES

BACKGROUND \nComputed tomography Peripheral angiography (CTPA) and Non enhanced magnetic resonance angiography (NE-MRA) are \naccurate techniques for selecting patients with peripheral arterial disease for surgical and endovascular treatment. No studies \nin the literature have directly compared CTPA and NE-MRA to establish which one should be employed, in patients suitable for \nboth techniques, before endovascular treatment. \nObjective- A Prospective study of 44 Patients was performed to compare the effectiveness of CTPA and NE-MRA in the \nevaluation of patients with peripheral vascular diseases. \nMATERIALS AND METHODS \nA prospective study was conducted over a period of twenty-three months (December 2016 to September 2018) on 44 patients \nwith clinically suspected Peripheral Vascular Disease. They were evaluated with 128 Slice CT Scanner (PHILIPS INGENUITY) \nand1.5 Tesla MRI (PHILIPS - ACHIEVA). \nRESULTS \nThe results of our study have shown that unenhanced MRA is a potential alternative or complementary modality to CTA for \nshowing clinically significant arterial disease in patients with the peripheral arterial disease with symptomatic chronic lower limb \nischemia. \nCONCLUSION \nCTA is a compulsion over NE-MRA in case if the patient is having absolute contraindications like cardiac pacemakers, aneurysmal \nclips, metallic implants, or undergone prior bypass stenting for peripheral arterial disease, and in case of emergency settings \nlike trauma. NE-MRA is an alternate modality to CTA in case if the patient is having renal insufficiency, severe diabetes who \nmay have calcified vessels and renal complications.
