| 目的 通过比较7个磁共振胰胆管成像(MRCP)序列在不同患者配合度的情况下胆囊三角的空间显示图像质量,优化MRCP检查方案。 方法 对100例患者行7个成像序列的MRCP检查,根据患者不同的屏气(B)与呼吸触发(R)配合度(1~3级)分成B1R1、B1R2、B1R3、B2R1、B2R2、B2R3、B3R1、B3R2、B3R3组,共9组。由2名放射科医师使用双盲法对重建后胆囊三角图像质量进行评价,并进行统计学分析。 结果 9组7个MRCP成像序列重建后胆囊三角图像质量评分差异有统计学意义(P<0.01)。B1R1组、B1R2组及B1R3组Fiesta 3D B图像质量最佳;B2R1组、B2R2组Fiesta 3D B、FRFSE 3D B、FRFSE 3D R图像质量好;B2R3组Fiesta 3D B、FRFSE 3D B图像质量好;B3R1组、B3R2组FRFSE 3D R图像质量最好;B3R3组FRFSE 3D B、SSFSE 2D B Thk图像质量好。 结论 腹腔镜胆囊切除术(LC)术前MRCP检查显示胆囊三角的最佳方案为:屏气配合度1级首选Fiesta 3D B;屏气配合度2级,呼吸配合度1级或2级的可选用FRFSE 3D R、Fiesta 3D B、FRFSE 3D B,呼吸配合度3级的可选用Fiesta 3D B、FRFSE 3D B;屏气配合度3级,呼吸配合度1级及2级的采用FRFSE 3D R,呼吸配合度3级的可选用FRFSE 3D B、SSFSE 2D B Thk。 |

| Objective To evaluate and compare the imaging quality of 7 different MR cholangiopancreatography (MRCP) sequences with different degrees of respiratory cooperation in patients, in order to optimize MRCP examination program. Methods MRCP examination with 7 different sequences was performed in 100 patients prospectively. According to the cooperation (grade 1-3) of breath holding (B) and respiratory triggering (R), the patients were divided into 9 groups: Group B1R1, B1R2, B1R3, B2R1, B2R2, B2R3, B3R1, B3R2 and B3R3. Qualitative analyses of the Calot's triangle on the reformatted imaging were performed independently by 2 radiologists. The differences of imaging quality among all the groups were evaluated statistically. Results Imaging qualities in 7 different sequences in 9 groups were statistically different (P<0.01). Fiesta 3D B sequence had the best imaging quality in groups of B1R1, B1R2 and B1R3. Fiesta 3D B, FRFSE 3D B and FRFSE 3D R sequence had better imaging quality for B2R1, B2R2. Fiesta 3D B, FRFSE 3D B sequence had better image quality for B2R3. FRFSE 3D R had the best image quality for B3R1 and B3R2. FRFSE 3D B, SSFSE 2D B Thk had better image quality for B3R3. Conclusion The best MRCP examination program for displaying Calot's triangle before laparoscopic cholecystectomy (LC) is: Fiesta 3D B for patients with the first degree of breath holding; FRFSE 3D R, Fiesta 3D B, FRFSE 3D B for patients with the first degree of breath holding and the first or second degree respiratory triggering, while Fiesta 3D B, FRFSE 3D B for the third degree of respiratory triggering; FRFSE 3D R for patients with the third degree of breath holding and the first or second degree respiratory triggering, while FRFSE 3D B, SSFSE 2D B Thk for the third degree of respiratory triggering. |
