    Abstract:
    We performed MRI in several recent cases of bladder cancer and prostatic cancer using a general coil or a 5-inch general purpose surface coil with or without Gd-DTPA. The surface coil improves the spacial resolution, density resolution and signal to noise ratio but reduces the field and the signal detection drops off as the depth from the surface increases. Moreover, additional time is required for patient positioning. In Gd-DTPA enhanced images of bladder cancer, the muscle layer became more distinct, and the images of tumor and bladder mucosa were enhanced, suggesting that facilitates evaluation of the extent of bladder wall invasion of the tumor. In Gd-DTPA enhanced images of prostatic cancer, the area conside to correspond to the tumor was enhanced. MRI using a surface coil and Gd-DTPA is considered to provide detailed information of bladder and prostatic cancer.
