Abstract: Aims and objective: To evaluate the efficacy of MDCT angiography and colour doppler ultrasonography to diagnose peripheral vascular disease in the lower limb. Materials and Methods: A comparative study included 30 patients with PAD who underwent colour doppler ultrosonography and MDCT angiography at the department of Radio-Diagnosis at K. S. Hegde Medical Academy following which their data was compared and analyzed with respect to wall calcification, wall thickening, stenosis and colllaterals. Results: In our study involving 30 patients in finding the agreement between the Doppler and MDCT of the lower limb arteries, the detection of calcification, stenosis, collaterals were significantly better in MDCT with a p value of <0.001. The detection of wall thickening was better in Colour Doppler. Conclusion: Imaging plays an important role in the management of the patients with peripheral arterial disease. Due to the limitations of the doppler ultrasound, CT Angiography is used prior to any vascular intervention is required in PAD. Doppler is also an effective tool which can detect the lesions to a comparable extent when no intervention is planned.
