Table 2:

Comparison of FHVs and parenchymal ischemic lesions between T2-FLAIR and T2-PROPELLER-FLAIR^{^a}

	T2-FLAIR	T2-PROPELLER-FLAIR	P Value
FHVs
FHV score	1.21 ± 1.47	3.50 ± 2.79	<.01
Parenchymal ischemic lesions
CNR	20.93 ± 8.61	8.43 ± 3.51	<.01
Sensitivity^{^b}	148/153 (96.7)	149/153 (97.4)	1.00

Note:—CNR indicates contrast-to-noise ratio: (SI_lesion − SI_WM) / SD_n.
↵a FHV scores were defined by counting the number of MCA-ASPECTS territories in which FHVs were present.
↵b Sensitivity for the detection of acute and old ischemic lesions. Data are the number of ischemic lesions and percentages.
