Table 1 Previous studies that identified IPH (or high signal intensity) using MP-RAGE

From: Semi-automatic carotid intraplaque hemorrhage detection and quantification on Magnetization-Prepared Rapid Acquisition Gradient-Echo (MP-RAGE) with optimized threshold selection

Study No of subjects Histology Threshold Reference tissue Field Intensity (T) Coil TR/TI (ms) Comments
Yamada et al. [9] 222 No 2.0 Adjacent muscle 1.5 Standard neck array and spine array coil 1500/660 Define high signal intensity regions
Hishikawa et al. [8] 35 Yes 2.0 Adjacent muscle 1.5 Standard neck array and spine array coil 1500/660 Define high signal intensity regions
Altaf et al. [3] 64 No 1.5 SCM 1.5 Receive-only quadrature neck array cervical spine coil 1462/741a Define regions for IPH
