Abstract:
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.
