Role of CT Angiography & Colour Flow Imaging (USG) in Evaluation of Peripheral Arterial Diseases

Purpose -To compare multidetector computed tomography (MDCT) angiography & colour flow imaging (USG) in evaluation of patients with peripheral arterial diseases. Also evaluate the role MDCT in providing information regarding collateral circulation in peripheral arterial diseases and aiding treatment planning in peripheral arterial diseases. Material and methods- CT angiography performed with Brilliance 64 slice CT scanner by Philips on 50 patients with clinical diagnosis peripheral arterial diseases T. he authors performed additional Doppler ultrasound examination. Result and Conclusion When colour Doppler USG and MDCTA are compared, MDCTA detects more stenotic or occluded arteries in supra-popliteal, infrapopliteal, whole leg comparisons & excellent diagnostic performance. Colour Doppler USG is useful screening tool, however in symptomatic patient for detailed evaluation, MDCTA is a semi-invasive, fast, and accurate alternative to DSA, and we believe MDCTA better detects stenotic or obstructed arteries than colour flow imaging (USG) in patients of PAD.
