摘要：

Objectives: To evaluate the efficacy of test injection technique using a monitoring scan at knee level for 64-slice multidetector row computed tomographic (MDCT) angiography of the abdominal and lower extremity arteries. Methods: The test injection technique using low-dose serial CT scan at knee level was per-formed for 58 patients. Time elapsed from contrast material injection to peak enhancement for the popliteal arteries was applied to scan delay for CT angiography. 64-Slice MDCT angiography of the abdominal and lower extremity arteries obtained with a table speed of 137.5 mm/s was evaluated. Results: The time to peak enhancement was unavailable in 2 cases. CT angiographic images were of good quality in 54 cases, whereas prominent enhancement of abdominal veins was observed in 2 cases. Conclusions: The test injection using a monitoring scan at knee level was found to be useful for 64-slice MDCT angiography of the abdominal and lower extremity arteries.
