Abstract:
Objective To discuss the value of Time-Resolved Imaging of Contrast Kinetics (TRICKS) in the diagnosis of lower extremity diseases. Methods 24 cases (27 times) with lower extremity, skeleton and blood vessel diseases undergoing TRICKS were retrospectively analyzed. There were 14 cases with both lower extremities two -segment scan, 5 cases(6 times) with one-segment scan(thigh), and 5 cases (7 times) with one-segment scan(calf). Conventional sequences were performed followed by enhanced MR angiography with the TRICKS technique. Results The TRICKS images for all cases satisfied the vascular changes and structure demonstration in arteriovenous phase, and the full circulative process of those pathological vessels were observed. The diagnostic accuracy of TRICKS angiography has been validated. Conclusion The TRICKS provides a method for imaging the change of blood flow. The vascularity in the target vascular and tumor can also be obtained. Hence TRICKS provide important information in clinical decision making.
