| 摘 要： | 目的回顾性分析12例恶性黑色素瘤的MRI表现，提高对恶性黑色素瘤的影像学认识。方法选取2006年3月-2008年5月经病理学诊断证实的恶性黑色素瘤12例，其中女性5例，男性7例，年龄42～76岁，平均年龄56．5岁。均行MRI平扫及增强扫描。观察分析恶性黑色素瘤不同类型的MRI表现。结果发生在眼球的黑色素瘤均呈短T1、短T2表现，强化均匀；颅内恶性黑色素瘤的MRI表现具有多样性。结论恶性黑色素瘤除具有典型的黑色素瘤的MRI表现外，由于肿瘤细胞所含黑色素浓度及分布的不同，其MRI表现具有多样性，须鉴别，充分认识其各种表现，有助于提高诊断。

| Abstract: | Objective To study retrospectively the MRI manifestations of the malignant melanoma, and raise awareness of its imaging features. Methods MRI scanning and enhanced scanning were performed in 12 patients definitely diagnosed as malignant melanoma from March 2006 to May 2008, male 7, female 5, aged 42 - 76 years, mean age 56.5 years. The different patterns of malignant melanoma were observed and analyzed . Results Malignant melanoma in eyeballs had short -T1 and short-T2 manifestations, enhancement was unifor... |
