【摘要】：目的探讨test-bolus技术在MRI肝动脉多期相扫描中的应用价值。方法搜集行上腹部MRI检查患者50例,采用完全随机化分为2组。经验组25例,采用传统经验性延迟时间扫描法;TB组25例,采用test-bolus技术,测得腹主动脉达峰时间,据此获得扫描延迟时间进行扫描。评价两种方法所得肝动脉三期图像质量并进行比较。结果经验组准确显示肝动脉早中晚三期者仅5例;TB组腹主动脉达峰时间不一,均能准确显示动脉早中晚三期,两组各期成像评分均有统计学差异(P值分别为0.039、0.013、0.047,均0.05)。虽然经验组肝动脉三期分期准确性低于TB组,但两组均能捕获肝动脉晚期图像(均为100%)。结论采用test-bolus技术可个体化准确捕捉肝动脉多期相;而对于肝动脉晚期的显示,则与传统方法无明显差别。
[Abstract]:Objective to evaluate the value of test-bolus technique in multiphase MRI hepatic artery scanning. Methods 50 patients with epigastric MRI were randomly divided into two groups. 25 cases in the experience group and 25 cases in the TB group were treated with traditional experiential delayed time scanning. The peak time of abdominal aorta was measured by test-bolus technique, and the scanning delay time was obtained. To evaluate and compare the quality of three phase images of hepatic artery obtained by two methods. Results in the experience group, only 5 patients with early, middle and late hepatic artery had different peak time of abdominal aorta in the TB group, and all of them could accurately display the early, middle and late stages of the artery. The imaging scores of each phase of the two groups were significantly different (P = 0.039 卤0.013, 0.047, respectively). Although the accuracy of stage 3 staging of hepatic artery in the experience group was lower than that in the TB group, both groups were able to capture the late hepatic artery images (both 100%). Conclusion the multiphase phase of hepatic artery can be accurately captured by test-bolus technique, but there is no significant difference between the test-bolus technique and the traditional method.
