Abstract
OBJECTIVE: To compare whole body magnetic resonance imaging (MRI) using fast sequences with radioisotope bone scintigraphy (BS) for the detection of metastases in the entire skeleton. METHODS AND RESULTS: In forty-four patients suffering from carcinoma of lung, breast and prostate whole body MRI could generally be accomplished in about 39 minutes and it was shown to have a higher skeletal metastases detection compared with BS in the spine, pelvis, limb bones, sternum, scapula, and clavicle, but lower in the ribs and skull. CONCLUSIONS: We think for addressing the status of skeletal metastases only, bone scintigram is still preferred over whole body MRI. When bone scintigram is unavailable, whole body MRI is a practical and acceptable alternative especially when extra-osseous metastases are also of concern.
