PIDS levels were similar for non-endorectal coil (NERC) and endorectal
coil cohorts (ERC). Rician noise was higher and strongly correlated with PIDS in
NERC compared to ERC. High PIDS coincided with motion artifacts and low signal.
It can be used as quantitative marker for quality in prostate.
Table 1. Average PIDS prevalence across the 40 ERC and 40 NERC subjects.
Figure 1. Example of
variations of the PIDS across TZ and PZ. A high PIDS value of 40% can be seen
in the TZ region (a) and (b), while in PZ region the PIDS is 9.6%. Similarly,
in another subject we can see a higher value of PIDS (33%) in PZ - (c) and (d),
compared to TZ.
