Abstract:
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.
