Table 5. Comparison of the T1, T2, PD, and ADC values in PCA with different GSs.

Parameter	GS =3+3	GS =3+4	GS =4+3	GS =4+4	GS =4+5	P
T1 (msec)	1,354±101.66	1,193 (1,118, 1,255)	1,259.88±146.19	1,261.91±105.00	1,267.24±114.61	0.005
T2 (msec)	71.57±7.48	73.53±7.53	77.40±9.27	79.00±9.56	77.05±8.34	0.025
PD (pu)	80.71±4.15	78.9 5±3.09	80.73±4.01	80.81±4.97	81.12±3.52	0.03
ADC (×10−6 mm2/s)	671±101.80	633 (604, 693)	594.07±94.60	581 (528, 652)	567.94±76.20	<0.001

Data following a normal distribution are expressed as the mean ± standard deviation. Otherwise, data are expressed as the median (first quartile, third quartile). PD, proton density; ADC, apparent diffusion coefficient; PCA, prostate cancer; GS, Gleason Score.
