Peripheral arteries are challenging to maneuver during X-ray guided recanalizations due to the absence of a lumen to hold contrast agents and the tortuous nature of the vessels. In this abstract, we investigate the use of a T1-weighted high-resolution 3-D Turbo Spin Echo MRI pulse sequence in combination with inner volume imaging to image and characterize occluded arteries within a reasonable clinical acquisition time of around 5-10 minutes with adequate signal-to-noise ratios at 1.5T with a view toward practical percutaneous X-ray revascularization.
