Three-Dimensional Dynamic Subtraction Contrast Enhanced Magnetic Resonance Angiography of the peripheral arteries--an
1Department of Imaging, Hospital Lam Wah Ee, Jalan Tan Sri Teh Ewe Lim, 11600 Pulau Pinang.
Abstract:
This is a prospective study with the objective of comparing Three Dimensional (3D) Dynamic Subtraction Contrast Enhanced Magnetic Resonance Angiography (3DDSCEMRA) with Conventional Catheter Arteriography (CCA) as the gold standard, in the diagnosis of peripheral occlusive disease. Three patients scheduled for CCA in this hospital in between September and October 2000 were included in this study. Patients underwent 3DDSCEMRA before proceeding to CCA on the same day. The 3DDSCEMRA reader was blinded to the CCA results. The results showed good correlation in iliofemoral segment and poor correlation in the infrapopliteal segment due to artifacts in 3DDSCEMRA images. 3DDSCEMRA is a new, non-invasive and promising technique in the diagnosis of peripheral occlusive disease.
