Myometrial invasion and cervical invasion by endometrial carcinoma: Evaluation by CO₂‐volumetric interpolated breathhold examination (VIBE)

Abstract

Purpose: To assess myometrial invasion and cervical invasion by endometrial carcinoma, using CO 2 -volumetric interpolated breathhold examination (VIBE) enabling more precise evaluation of depth of tumor invasion.Materials and Methods: CO 2 -VIBE was performed in 21 cases of endometrial carcinoma (Stage Ia-IIb) prior to treatment. The images were interpreted by performing multiplanar reconstruction (MPR), and the findings obtained from the images (degree of myometrial invasion and presence or absence of cervical invasion) were assessed in comparison with the histopathological diagnosis. Results:The sites of the endometrial carcinoma lesions were clearly visualized by the CO 2 -VIBE method. Evaluation of the degree of myometrial invasion enabled a high correct diagnosis rate of 90.5%, and evaluation for the presence of cervical invasion also allowed a high correct diagnosis rate of 90.5%. Conclusion:VIBE permits evaluation of any plane desired by means of thin slices, and it is a truly revolutionary method for preoperative evaluation of depth of invasion of endometrial carcinoma that enables highly accurate determination of the extent of lesion sites and degree of invasion before treatment.

Diffusion-Weighted Single-Shot Echo-Planar Imaging with Parallel Technique in Assessment of Endometrial Cancer

“…This capability improves the contrast resolution of the tumor and myometrium. In previ-ous studies [13][14][15], combining T2-weighted TSE with dynamic MRI improved staging accuracy from 61% to 90%. In our study, endometrial cancer was found to have high signal intensity on DWI; thus the boundary between cancer and normal myometrium was clearly depicted.…”

Diagnostic Accuracy of MRI for Detecting Cervical Invasion in Patients with Endometrial Carcinoma: A Meta-Analysis

“…With the development of functional MRI imaging, diffusion weighted imaging (DWI) and dynamic contrastenhanced MRI (DCE-MRI) are increasingly applied to detect cervical infiltration in endometrial carcinoma [10][11][12][13][14]. Many studies have investigated the accuracy of MRI for detecting cervical invasion [6,[12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. These studies differ in the MR pulse sequences, magnetic field strength, and number of patients, so the results are diverse.…”
