In this study, an inflatable single loop and rigid dual
channel endorectal coil were compared for prostate
imaging at 3T. Twenty-two patients were included and T1
weighted images were used for a SNR analysis. At close
distances from the coil, the SNR in the prostate was
higher for the rigid coil compared to the inflatable
coil. The increase in SNR may be used to increase the
spatial resolution of T2 weighted images, though in this
study the 2.4 fold increase in in-plane spatial
resolution led to image quality metrics somewhat less
than those found with the inflatable coil.
