Aim: To report on our initial experience with whole body diffusion weighted MRI (WB-DWMRI) for cancer staging, using the Metastasis Reporting and Data System for Prostate (METRADS-P) criteria and scoring, aiming at finding evidence of visceral/and or bony metastasis in already diagnosed tumor cases involving different types of tumors. Methods: The study involved 34 known oncological patients who were referred for cancer staging with Whole Body Diffusion Weighted MRI (WB-DW-MRI) at our center within the period of the study. WB-DW-MRI was performed on a 1.5T clinical scanner recently installed in our center. Scans were performed using 6 Channel body phase array coils isocenter matrix coil (spine coil) and 16 Channel Head/Neck Coil. Patients were examined in supine position and four stations of axial free breathing Diffusion Weighted Imaging (DWI). Results: Majority of our study population were males, recording a mean age of 60.2 years. The lesions indicated for WB-DW-MRI included prostate cancer, breast cancer, uterine cancer, gastric cancer, Non-Hodgkin lymphoma, Burkitt’s lymphoma, rectal cancer and lung cancer. Prostate cancer was the most common lesion (n=25, 73.5%). Visceral and/or bony metastasis was evident in 12 out of the 34 cases reported, majority of which were prostate cancer cases. Conclusion: Whole body diffusion weighted MRI has proven to be effective in assessing visceral, nodal and bony metastasis in various types of malignancies in a black African population. Based on this experience, we reinforce the recommendation that WB-DW-MRI should be integrated into routine clinical practice.
