【摘要】 目的:探讨血液疾病骨髓磁共振成像信号特点、分型与病理基础。资料与方法:经病理证实白血病(AL)20例,骨髓纤维化(MF)6例,多发性骨髓瘤(MM)3例,再生障碍性贫血(AA)3例,行腰椎、髂骨、股骨中上段骨髓SE及增强,脂肪抑制各序列成像磁共振成像检查,分析骨髓信号的分布与形态特点并分型。结果:按骨髓磁共振成像表现以及病变扫描部位的信号强度、形态及病变范围等分为4种类型:Ⅰ型,正常骨髓信号。Ⅱ型,不规则形信号。Ⅲ型,弥漫性斑片状信号。Ⅳ型,弥漫性信号变化。结论:血液疾病骨髓信号的分布与形态具有一定的规律,反映了相应的病理基础。将其总结分型,便于正确认识血液疾病骨髓信号的变化,提高诊断水平。更多还原

【Abstract】 Objective: To research the characteristics of MRI, lesion pattern, pathological base of bone marrow in hematologic disease. Materials and Methods: In 32 cases, 20 cases were AL, 6 cases were MF, 3 cases were MM and 3 cases were AA. Bone marrow MRI was obtained by SE, fat-suppression sequence, and contrast enhancement of vertebrae, pelvis and femur. MRI signal classification was made according to the characteristics of signal distribution and morphological characters. Results: MRI features included: patternI(normal, 5 cases), pattern II(irregular signal, 3 cases), pattern III(diffuse spotty signal, 23 cases), pattern IV(diffuse changes in signal intensity, 9 cases). Conclusion: Distribution and appearance of bone marrow signal in hematologic diseases had some regularities, which represent their corresponding pathological basis. Summarizing the MRI signal pattern of bone marrow in hematologic diseases were helpful to correct recognizing MRI signal changes of bone marrow and increase diagnostic level of hematologic disease.更多还原
