DOI : 10.9739/uvcd.2012-31619 Objective: Comparison of diagnostic efficiency of color Doppler ultrasound imaging (CDUS), 3-D MR angiography with digital subtraction angiography in lower extremity peripheral arterial occlusive disease. Material and Methods: The study encompassed 21 (18 males and 3 females) consecutive patients who were admitted to the DSA unit with the complaint of intermittent claudication and to whom DSA, CDUS and 3-D MRA studies were conducted and compared. A total of 21 patients, including 40 extremities and 270 arterial segments were assessed. All the studies were bilateral except 2 cases. Every extremity, including the main iliac, external iliac, femoral, popliteal, anterior tibial and posterior tibial proximal and distal segments were examined. Subjects were divided into three groups according to the stenosis levels which were 0-49%, 50-99% and total occlusion. DSA was considered as the gold standard and kappa and Mc Nemar statistical tests were employed. Results: For the lower extremity the sensitivity and specificity of CDUS to diagnose significant stenosis were 87% and 97% respectively. Kappa correlation with DSA was 0.82. For occlusion the sensitivity and specificity were 81% and 99% respectively. Regarding stenosis the sensitivity and specificity of 3-D MRA were 98% and 98% and kappa coefficient was 0.93. For occlusion the sensitivity and specificity were %93 and 98%. Conclusion: For general examination of the lo- wer extremity, 3-D contrast MRA imaging can be used as an alternative to DSA. CDUS can be used instead of DSA in the suprapopliteal region but differs from DSA in the infrapopliteal region. Due to its high specificity CDUS is suitable as screening test.
