Abstract:
0bjective To evaluate the application of whole body MR diffusion weighted imaging (DWI)in the detection of bone metastasis using skeletal scintigraphy as the referenee.Methods Fonv.two healthy volunteers and 38 patients with malignant tumors were enrolled in our studv.A11 the patients received MR examination and skeletal scintigraphy within one week.MR examination was performed on GE signa 3.0T MR scanner using a build.in body coil.The skeletal system Was divided into eight regons and the images of the whole body MR DWI and skeletal seintigraphy were reviewed to compare the two modalities patient by patient and region by region.The images were reviewed separately by two radiologists and two nuclear medicine physicians,who were blinded to the results of another imaging modality.Results A total of 169 metastatic lesions in 69 regions of 30 patients were detected by whole body MR DWI while 156 lesions in 68 regions of 29 patients were identified by skeletal seintigraphy.There were two cases negative in scintigraphy but positive in whole body MR DWI and one case positive in scintigraphy only.There were eight lesions negative in scintigraphy but positive in whole body MR DWI,mainly located in the spine.pelvis and femur.Seven 1esions were only detected by scintigraphy,mainly located in the skull.sternum.clavicle and scapula.Conclusion The whole body MR DWI reveals excellent consistency with skeletal scintigraphy regarding bone metastasis.and the two modalities are complementary for each Other.
