磁共振全身弥散加权成像在骨转移瘤诊断中的应用价值
Usage of whole-body diffusion weighted imaging in diagnosis of bone metastasis
摘要
Abstract
Objective To study the using value of whole-body diffusion weighted imaging in diagnosis of bone metastasis. Methods Forty-one patients with pathologically confirmed malignant tumors underwent WB-DWI. Meanwhile, conventional MRI or CT over suspicious sites was performed. The diagnosis result of WB-DWI were compared with conventional MRI/CT and clinical information including biopsy pathologic examination, diagnostic treatment and the results of follow-up observation in order to evaluate the accuracy of WB-DWI on detection of bone metastasis. Results Sixty-seven metastatic bone lesions were found by WB-DWI, 6 lesions missed including 2 lesions in skull, 1 lesion in scapula, 1 lesion in sternum and 2 osteogenic bone metastasis in lumbosacral spine. Two angioma in centrum were misdiagnosed. Two lesions in rib detected by WB-DWI were missed by conventional MRI/CT. Sixty-nine metastatic bone lesions were detected by conventional MRI/CT, among them, 63 lesions coincided with WB-DWI. Conclusions WB-DWI has higher applied value on early diagnosis of bone metastatic lesions.关键词
