Results: MR examination of bone contusion were mostly less than two weeks, but a few patients were longer than one year: STIR, TIWI were more sensitive lesion detection series in hone contusion (100% and 95.7%). Bone contusion mostly occur at knee, and lesions mainly distributed in the margin area of articular (69.8%), in superior portion of vertebral body(74.l%). Bone contusion following-up showed a line-like hyperostosis and osteosclerosis in contusion area. Histological manifestations of bone contusion were local trabecular micro fractures, edema, hemorrhage and injury of fat tissue.

结果：1多数骨挫伤MRI检查在两周内完成，少数病人时间超过1年；2检出骨挫伤敏感的MRI序列为STIR及T1W/I（100%及95.7%）；3膝关节是骨挫伤的好发部位，病灶主要分布于骨边缘区(69.8%)，在脊柱主要分布于椎体上缘终板下(74.1%)；4骨挫伤影像随访提小病变区出现线状骨质修复，骨髓水肿吸收；5骨挫伤病理为骨小梁显微骨折，骨髓水肿、出血和脂肪损伤。

Results (1) 6 cases of Tuberous Sclerosis. Diffused subependymal nodular calcification lesions were found in all cases on unenhenced CT. 4 patients are 2 pairs of mother/child relationship. Both of the two mothers are found to suffer from renal angiomyolipoma.(2)1 case of neurofibromatosis showed abnormal spinal canal: scoliosis of thoracic and lumbar spine, concave change of vertebral posterior border. Bilateral renal hypogenesis was found in this patient. Diffused hyper-density lesions were found in kidney and fatty accumulation was found in back skin.(3)6 cases of Sturge-Weber syndrome. On unenhenced CT, curving and strip-shaped calcifications were found along the parietal and occipital gyrus.

结果 ①结节性硬化6例，所有病例CT平扫见两侧脑室室管膜下多发小结节状高密度钙化灶，其中4例为两对母子关系，并见两位母亲合并有肾脏错构瘤，；②神经纤维瘤病1例，MRI表现为椎管异常，胸腰段脊柱侧弯，椎体后缘呈明显的切凹改变；伴有双肾发育不良，CT示肾内多个高密度影，背部皮肤多量脂肪堆积，③脑颜面血管瘤综合征6例， CT可见顶枕部沿脑回分布的弯曲的条状高密度钙化，部分延伸致侧脑室内，增强后见病灶内有扭曲的条状和结节状明显强化的血管影；④小脑血管瘤病4例，影像学表现为小脑内大囊、小结节样占位性病变。
