| 摘 要： | MRI is a non invasive powerful imaging tool andhas been used in the diagnosis of various prostate dis eases. The excellent soft tissue contrast provided byMRI allows improved visualization of the prostateanatomy, surrounding critical structures (such as theneurovascular bundles and periurethral zone), and theextent of tumor spread. This improved contrast reso lution presents a distinct advantage over otherprostate imaging modalities such as transrectal ultra sound and comp… |

| Abstract: | The diagnosis of prostate diseases by magnetic resonance imaging (MRI) in vivo is sometimes difficult for the lower signal to noise ratio (SNR). To increase the SNR of the prostate image, we designed a RF coil that can be inserted into rectum 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. |
