Figure 1: Accelerated and quantitative T-weighted dynamic glucose enhanced MRI applied in the study of a patient with a glioblastoma at B0 = 7T.

From: Fast and Quantitative T1ρ-weighted Dynamic Glucose Enhanced MRI

Figure 1

(a) T2-weighted image acquired at 7T, (b) gadolinium-enhanced T1-weighted (GdCE-T1w) image acquired at 3T, (c) fusion of the GdCE-T1w image and the T-weighted dynamic glucose enhancement (DGEρ) obtained at t = 588 s. (d) Unsmoothed DGEρ time curves with a temporal resolution of less than 7 seconds in a tumor-ROI selected on DGEρ (ROI #1), a second tumor-ROI selected on the GdCE-T1w image (ROI #2), and a ROI in normal appearing white matter (ROI #3). The error is given by the standard deviation of 5 consecutive data points and the ROIs are marked in the GdCE-T1w and DGEρ image shown in the top left corner. Increasing DGEρ values are obtained in both tumor-ROIs after the end of the glucose injection. The red arrow marks an abrupt signal drop induced by patient motion. (ei) DGEρ images (average of 5 consecutive images) at different time points after glucose injection. Note the hyperintense region at the bottom of the tumor area (black arrow; (g)), which is not visible in the GdCE-T1w image (b).
