Intraventricular Hemorrhage

Intraventricular hemorrhages (Figs. 6.5 and 6.7) are well demonstrated on FLAIR, T1-, T2- and proton density-weighted images [34, 59, 70-72]. FLAIR has been reported to have the highest sensitivity for detection of intraventricular hematomas [71]. DW images can demonstrate intraventricular hemorrhages, but in general the GRE images have a higher sensitivity [31].

Figure 6.7 a-f

Intraventricular hemorrhage (intracellular met-hemoglobin). A 78-year-old woman with headache after thrombolytic therapy for femoral artery occlusion had a CT scans 6 hours after surgery (a). This shows intraventricular hemorrhage in the bilateral lateral ventricles (arrows). Three days after surgery (b-f), the T2-weighted image (b) shows hypointense lesions in the bilateral lateral ventricles with fluid-fluid levels (arrows) and the Tl-weighted image (c) shows hyperintense lesions in the same distributions (arrows).The DW image (d) shows hypointense lesions (arrows) with surrounding hy-perintensities.These are ascribed to magnetic susceptibility artifacts.The b0 image (e) also shows hypointense lesions (arrows). These hypointensities are more prominent than on the T2-weighted images (b). The ADC map (f) shows hypointense lesions (arrows)
