From: Terahertz reflectometry imaging for low and high grade gliomas
Discrimination of low and high grade of human gliomas with TRI.
(a) Terahertz parameter (TP) values from regions of interest (ROIs) in tumors (n = 14), normal gray matters (n = 4), and normal white matters (n = 4). (b) Quantification of threshold value 1 (TH1) and TH2 (dashed red and green lines, respectively) for tumor discrimination using the data shown in (a). Data represent mean ± SD. ***P < 0.001 (Kruskal-Wallis test.) Representative cases of grade IV, III and II gliomas, characterized by (c) TRI images and (d) H&E stained image. Red regions indicate regions with TP value over TH1. The capitals A–G shown in (d) correspond to the ROIs in (c).
