医学影像学杂志000107摘 要：目的本文通过26例卵巢病变的影像学、手术与病理学的对照研究，着重探讨MRI对卵巢肿瘤的诊断价值与鉴别诊断能力。材料与方法MR检查常规采用体线圈、SE序列、横断位与矢状位扫描，根据需要补充冠状位扫描，扫描范围自脐至耻骨联合。结果26例年龄从19～71岁，症状主要为盆腔肿块，下腹部疼痛或压疼。术前均作经阴道D-US与MR检查。经手术与病理证实单侧卵巢肿块14例，双侧12例。计卵巢病变38个。其中囊性肿块24个，实质性肿块14个。囊性病变中除2例囊腺癌外，1例有恶变，其余皆为良性肿块。卵巢恶性肿瘤(9例)的特点是：①肿瘤大，且多为实质性不规则肿块，通常侵犯双侧卵巢；②囊性肿块其囊壁厚>3mm，常有附壁结节；③常伴瘤内坏死、腹水以及盆腔内浸润转移。结论MR具有多方位扫描，软组织分辨率高的特点，对盆腔肿块病灶检出率(36/38，94.7%)，定性诊断率(32/36，88.8%)以及对判明盆腔脏器的解剖结构等方面，比D-US及CT扫描有更多的优越性。

Abstract：Purpose Based on the control study of the image, operation and pathology of 26 eases of ovary lumps, this paper studlied the diagnostic value and capacity of differential diagnosis of MRI of ovary lumps. Materials and methods Examination of MRI usually used body coil, SE sequence, transverse positon and sagittal scanning. If necessary, coronary scanning is also used. The seope of the scanning is from navel to pelvic symphysis. Results The ages of the patients were from 19 to 71 year. The main symptoms of the disease were pelvic masses, pain or pressure pain in low stomach. All of the patients were examed by the D-US and MRI through vagina before operation. Operation and pathology verified that there were 38 ovary wnps were 38,within them,24 cases were cystic lumps while the solidary lumps were 14. Excepting 2 cases of cystic adenocarcinoma and 1 case of malignant change(canceration),the other cystic lumps were benign masses.The characteristics of the ovary malignant tumor(9 cases )were:① The tumors were big and always solidary and irregular masses. They often invaded the two sides of ovaries, ② In cystic lumps,the wall was usually thick (>3mm)and have mural nodules,③ The tumor always have a concomitant necroses inside the tumor, ascites and invasive in to pelvic cavity. Conclusion MRI can give a three-dimemional scanning and has a high resol power for the soft tissue. Comparing with D-US and CT, it has a great advantage the focal detectable rate(36/38,94.7% ) ,qualitative diagnostic rate(.32/36,88.8% )and in judgement of the anatomical structure of the organs in pelvic cavity.
