Article Figures & Data
Figures
- fig 1.
TDL in a 22-year-old woman.
A, Contrast-enhanced T1-weighted image (600/14/1) shows a well-circumscribed solidly enhancing mass in the right frontal lobe.
B, Fluid-attenuated inversion recovery image (9000/110/1) shows a mild degree of signal abnormality around the lesion.
C, Color overlay of rCBV map shows no evidence of increased blood volume.
- fig 2.
Glioblastoma multiforme in a 63-year-old woman.
A, Contrast-enhanced T1-weighted image (600/14/1) shows a well-circumscribed mass in the left frontal lobe.
B, T2-weighted image (3400/119/1) shows minimal edema and mass effect.
C, Color overlay of rCBV map shows marked increase in blood volume.
- fig 3.
TDL in a 37-year-old man.
A, T2-weighted image (3400/119/1) shows a large hyperintense mass lesion in the right parietal lobe. There are no visible flow voids within the lesion.
B, Unenhanced T1-weighted image (600/14/1) shows hypointense signal of the lesion.
C, Contrast-enhanced T1-weighted image (600/14/1) shows heterogeneous enhancement of the medial aspect of the lesion in a concentric pattern.
D, Dynamic T2*-weighted image (1000/54/1) obtained before IV administration of contrast agent.
E, Dynamic T2*-weighted image (1000/54/1) obtained during IV administration of contrast agent shows several periventricular, linear vessel-like structures (arrows) running through the center of the lesion near a dilated subependymal vein. The dominant lesion itself shows no signal loss.
F, Dynamic T2*-weighted image (1000/54/1) obtained 50 s after IV administration of contrast agent shows return of brain signal to baseline, with residual signal loss within the aforementioned linear vessel-like structures.
