Abstract
The diagnosis os prostate diseases by magnetic reasonance imaging (MRI) in vivo is sometimes difficult for the lower signal to noise ration(SNR). To increase the SNR of the prostage image, we designed a RF coil that can be inserted into return and was named endorectal coil. The properties of RF coil were evaluated using a network analyzer. Moreover the images and spectroscopy of a special phantom were acquired and the results were compared to those of the commercial TORSO coil (G.E. Medical Systems, USA). Our coil gave a significantly higher SNR at the region of interest (ROI). The achieved high local SNR and resulting high spatial resolution would add more anatomic and biochemical information to the diagnosis of prostate diseases.
