目的：分析各种子宫良性肿瘤ＭＲＩ 图像，探讨ＭＲＩ 在子宫良性肿瘤中的诊断价值。材料和方法：共收集本院１９９４ － １９９９ 年临床疑子宫良性肿瘤病人３９ 例。ＭＲＩ 检查在ＧＥ Ｖｅｃｔｒａ０ ．５Ｔ 和ＧＥｓｉｇｎａ Ｈｏｒｉｚｏｎ１ ．５Ｔ 超导成像仪上进行，采集矢状面ＦＳＥ Ｔ２ ＷＩ 像，横断面ＳＥ Ｔ１ ＷＩ 像和ＦＳＥ Ｔ２ ＷＩ 像，并对各种病变所致子宫和宫颈的位置、大小、外形与其各层结构变化进行仔细观察和分析，与手术病理对照，以确定ＭＲＩ 的诊断价值。结果：３９例ＦＳＥ Ｔ２ ＷＩ 图像均清晰显示子宫及宫颈诸层结构；矢状面更可清楚显示子宫位置和大小。３９ 例病变均经病理证实，２３ 例为子宫肌瘤，子宫形态均增大，连结层和内膜层可受压，其中１７ 例Ｔ１ ＷＩ 和Ｔ２ ＷＩ 上表现为低信号影，６ 例为低到高不均匀信号影。１２ 例为子宫腺肌瘤，Ｔ２ ＷＩ 上连结层结构不清及较低信号，且增厚。１ 例为纳氏囊肿，Ｔ１ ＷＩ 上为子宫颈后壁内低信号囊状影，边缘光滑，Ｔ２ ＷＩ 上为均匀高信号影。本组有１ 例多发性肌瘤出血ＭＲＩ 上被误诊为子宫腺肌瘤；有２ 例子宫浆膜下肌瘤似游离于盆腔内，而漏诊。结论：ＭＲＩ 横断面及矢状面ＦＳＥ Ｔ２ ＷＩ 能清晰显示
Objective: To analyze the MRI images of various uterine benign tumors and discuss the diagnostic value of MRI in benign uterine tumors. Materials and Methods: A total of 39 patients with suspected benign uterine cancer in our hospital from 1994 to 1999 were collected. MRI examination at GE Vectra0. 5T and GEsigna Horizon1. 5T superconducting imager, the sagittal FSE T2 WI image, the cross-sectional SE T1 WI image and the FSE T2 WI image were collected, and the position, size, shape and structure changes of the various layers of the uterus and cervix Careful observation and analysis, and surgical pathology control to determine the diagnostic value of MRI. Results: The images of 39 cases of FSE T2 WI clearly show the structure of uterus and cervix. The sagittal plane can clearly show the position and size of uterus. Thirty-nine cases were pathologically confirmed, 23 cases of uterine fibroids, uterine morphology were increased, the junction and endometrial layers can be compressed, of which 17 cases showed low signal intensity on T1 WI and T2 WI, 6 cases were low Highly uneven signal shadow. 12 cases of uterine adenomyosis, T2 WI on the junctional structure unclear and lower signal, and thickening. One case had a neoplasia cyst. The T1 WI was a low-signal cyst shadow in the posterior wall of the cervix with a smooth edge and a uniform high signal intensity on the T2 WI. This group had a case of multiple myoma hemorrhage MRI was misdiagnosed as adenomyosis; 2 cases of subserosal fibroids like free pelvic, and missed diagnosis. CONCLUSIONS: MRI cross-sectional and sagittal FSE T2 WI can be clearly displayed
