Prognostic Parameter	Mean ADC Value for EPI-DWI (× 10⁻³ mm²/s)	P Value for EPI-DWI	Mean ADC Value for HASTE-DWI (× 10⁻³ mm²/s)	P Value for HASTE-DWI
Tumor grade
Poorly differentiated (n = 13)	0.59 ± 0.16	.37	0.79 ± 0.16	.22

Absent (n = 9)	0.68 ± 0.15		0.85 ± 0.16
Anterior eye segment enhancement on postcontrast MRI
Present (n = 6)	0.70 ± 0.18	.056	0.91 ± 0.23	.15
Absent (n = 15)	0.58 ± 0.10		0.80 ± 0.13

↵^aOther histopathologic characteristics (eg, invasion of iris, ciliary body, anterior chamber, and sclera) were not found in any patient.
↵^bP value is for ADC values in cases with postlaminar invasion versus cases with prelaminar or absent invasion.
