目的：探讨多层螺旋(MSCT)最大密度投影-多平面重组(MIP-MPR)技术对结肠癌周围局部淋巴结检出的价值。方法回顾性分析本院经手术病理证实的33例结肠癌的 MSCT 原始影像资料,患者均采用256层螺旋 CT 行三期动态增强扫描,将薄层容积扫描数据在工作站进行后重组处理,获得兴趣区的 MPR 和 MIP-MPR 图像,计算结肠癌周围局部淋巴结的数量,2种方式图像均在相同层面,依据淋巴结的大小分成3组(短径分别为3.0~5.0 mm、5.1~10 mm,10.1 mm 以上),采用配对检验比较2种成像技术对不同组别淋巴结检出的敏感性。结果 MSCT MPR 与 MIP-MPR 在3组检出淋巴结均数(x ±s )分别为：1组3.66±1.99,6.09±2.44,t=11.6,P 值0.00<0.05；2组3.72±1.79,4.03±1.89,t =3.73,P 值0.01<0.05；3组1.21±1.31,1.27±1.46,t=1.44,P 值0.16>0.05。前2组 P 值<0.05,有统计学差异,第3组 P 值>0.05,无统计学差异。MIP-MPR 技术在对结肠癌周围局部小、中淋巴结检出的敏感性较常规 MPR 高。结论MSCT MIP-MPR 是对结肠癌周围局部较小淋巴结检出较好的技术。

Objective To explore the diagnostic value of multi-slice spiral CT MIP-MPR image in regional lymph node metastasis of colonic carcinoma.Methods CT findings of 33 cases with pathological confirmed colonic carcinoma were analyzed retrospectively . All patients were underwent three-phase 256-slice CT dynamic enhancement scanning.All data were processed in workstation,to obtain routine MPR and MIP-MPR image.The regional lymph nodes of colon cancer were counted,and divided into 3 groups accord-ing to the short diameter of lymph node:group I (3.0-5.0 mm),group Ⅱ(5.1-10 mm),and group Ⅲ(10.1 mm up).The diag-nostic sensitivity of CT MPR and MIP-MPR image in checking out lymph nodes of different groups was compared by paired test.Re-sults The average value(x ±s )of lymph node number of three groups with routine MPR and MIP-MPR image were:group I, 3.66±1.99,6.09±2.44 (t=1 1.6,P <0.05);group Ⅱ,3.72±1.79,4.03±1.89 (t=3.73,P <0.05);group Ⅲ,1.21±1.31, 1.27±1.46(t=1.44,P >0.05).There were statistical differences in group I and group Ⅱ.Sensitivity of MIP-MPR image in chec-king out regional small and middle lymph nodes of colonic carcinoma was higher than routine MPR image.Conclusion Multi-slice spiral CT MIP-MPR image is a good way to checking out regional small and middle lymph nodes of colonic carcinoma.
