The bone marrow is a common site for metastasis in cancer. Accurate detection of bone marrow metastases is of major importance because of its therapeutic and prognostic implications. MRI allows direct visualization of all bone marrow components at a good spatial resolution. Furthermore, thanks to technologic advances, it is now possible to perform MRI of the entire body. For these reasons, it is a potentially valuable technique for the detection of bone marrow metastases. This article reviews whole-body MRI techniques and the diagnostic performance of whole-body MRI compared with PET for the detection of bone marrow metastases.
