Teaching point: Whole body MRI has been widely used. However, the standard protocol is not established. In this exhibit, we introduce an example of the imaging protocol of WB-MRI, especially, to show the usefulness of fused image of coronal DWI and T1WI of body. The purposes of this exhibit are: 1. to introduce the imaging protocol which is used in our department. 2. list the various metastatic bone tumor and multiple myeloma. 3. to show the importance of coronal images. The major teaching points of this exhibit are: 1. how to improve the image quality of DWI of 3T MR machines. A technique to shorten the echo time, reduce bulk susceptibility artifacts and spatial distortions without significantly affecting SNR or scan time is explained. 2. to introduce the usefulness of the fused image combining the DWI coronal maximal intensity projection images and coronal T1-WI. 3. to teach a method for analyzing the images or comparison of other imaging modalities such as CT and FDG-PET/CT.

1. Femoral involvement of multiple myeloma 2. Multiple bone metastases from prostate cancer 3. Femoral metastasis from testicular tumor 4. Vertebral metastasis from hypopharyngeal cancer 5. Retroperitoneal metastases from leiomyosarcoma
