The aims of this exhibit are to   1) understand basic concept of subtraction CT angiography. 2) get to know the difference between manual position matching technique and semi-automated position matching technique. 3) come to know the diagnostic accuracy of subtraction CT angiography in comparison with invasive angiography.

A. Back ground: the limitations in current imaging procedures for peripheral arterial occlusive disease - including invasiveness in conventional angiography, radiation dose, renal dysfunction due to arteriosclerosis, and time consuming post processing and evaluation. B. Advantage of subtraction CT angiography: its accuracy in comparison with digital subtraction angiography. C. Position matching technique for subtraction CT angiography: the basic technique required in scanning and post-processing techniques D. Clinical application: Presentation in case with severe arterial calcification including cases who underwent hemodialysis
