Introduction : PAD is an atherosclerotic occlusive condition in which plaque builds up in the distal arteries. Until 10 years ago, conventional angiography and digital subtraction angiography were the only angiographic techniques used in peripheral vascular disease and are considered gold standard. However, the complications and patient discomfort associated with these techniques have prompted the need of less invasive means of assessing the peripheral arterial system. Aim of the study was to compare efficacy of USG and MDCT angiography for investigating the lower limb arterial disease. Method: 40 patients suspected of lower limb PAD were included. Patients with previous amputation surgery were excluded. In all patients color Doppler sonography and multi-detector CT angiography was done. A comparative study of multi-detector CT angiography and color Doppler sonography was undertaken. Result: 50% patients had complaints in left lower limb and 25% in right lower limb. 22% had bilateral lower limb pain which was more on the left side (12%). Three patients examined by angiography showed irregularity of arterial wall on both sides, which appeared as calcifications on CT angiography (sensitivity 100%) while only 2 of them appeared on color coded Doppler examination (sensitivity 75%). Conclusions: Color Doppler USG is the initial modality of choice in PAD. CT Angiography is a better for segmental length assessment, collateral circulation along with a road map reproduction of the arterial system. USG is better than CT angiography in diagnosis of Grade 1 &2 cases, with better assessment of soft plaques, segmental flow and recanalization in PAD.
