Bone metastasis is a leading cause of morbidity and mortality for patients with metastatic prostate cancer. Early detection of bone metastasis plays a key role in the assessment of treatment methods and prognosis. This study aims to evaluate the diagnostic efficiency of readout-segmented whole body diffusion weighted imaging in the detection of bone metastases for patients with newly diagnosed high-risk or biochemical recurrent prostate cancer. The result shows that RESOLVE whole-body DWI has higher sensitivity, specificity and accuracy in bone metastasis detection than bone scintigraphy using 99mTc-MDP (BS).
