MR imaging is frequently correlated to histopathology of specimen, and their high-resolution imaging is required. However, it is not usually feasible using the whole-body human MR scanner. We implemented inductively coupled small diameter coils insertable to the knee coil at 7T without modification of the coil interface. Up to isotropic 50 μm imaging was successfully conducted, and fine details of the specimen could be visualized using the same sequence for in vivo scans. The proposed coils are easy to use and will facilitate investigation of image-histopathology correlation.
