| 目的 探讨MRI测量早期宫颈癌间质浸润深度的准确性。方法 回顾性分析66例早期宫颈癌患者术前MRI资料，包括T2WI、DCE-MRI和DWI等，测量宫颈间质浸润最大深度，据此将肿瘤分为浸润型（包括深层浸润、双向浸润）和腔内生长型。分析MRI测量值与病理结果的一致性，比较3种MR序列图像测量宫颈间质浸润最大深度与病理结果的差异。结果 66例宫颈癌中，浸润型48例，其中31例深层浸润、17例双向浸润型，腔内生长型18例。T2WI、DCE-MRI和DWI测量宫颈间质浸润最大深度与病理结果的一致性均为中等（ICC=0.66、0.57和0.60，P均<0.05），3种图像之间测量值与病理结果差值的差异均无统计学意义（F=5.95，P均>0.05）。MRI对于浸润型宫颈癌的测量结果与病理结果的一致性优于腔内生长型。结论 MRI测量早期宫颈癌间质浸润深度的准确性较好，且对浸润型优于腔内生长型。 |

| Objective To investigate the accuracy of MRI measurement of early cervical carcinoma invasion depth of stroma. Methods Preoperative MRI data, including T2WI, DCE-MRI and DWI of 66 early cervical cancer patients were retrospectively analyzed. The maximum depth of cervical interstitial invasion was measured on MRI. The tumors were divided into infiltrating type (including deep infiltrating and two-way infiltrating)and intraluminal growth type. The consistency of MRI measurements and pathological results were analyzed, and the difference values of the maximum depth of cervical interstitial invasion measured by 3 kinds of MRI and pathological results were compared. Results Among 66 patients, deep infiltrating was observed in 31 cases, two-way infiltrating in 17 and intraluminal growth type carcinoma in 18 cases. The maximum depth of cervical stromal infiltration measured on T2WI, DCE-MRI and DWI were all moderately consistent with pathological results (ICC=0.66, 0.57 and 0.60, all P<0.05). No statistical difference of the difference of MRI and pathological results was found (F=5.95, all P>0.05). MRI measurement of invasive tumors, especially for those with deep infiltrating had superior consistent with pathological results than that of intraluminal growth tumors. Conclusion MRI has good accuracy in measuring the depth of interstitial invasion of early cervical cancer, for tumors with deep infiltrating is better than for intraluminal growth type tumors. |
