Advanced Imaging Modalities in the Detection of Cerebral Vasospasm

Figure 6

PET. Sequential PET studies of a patient with a ruptured PCA aneurysm. The first study (left column) shows day 2 after rupture with no rCBF abnormalities. The second study (middle column) shows day 10 after rupture with globally decreased rCBF indicating widespread vasospasm in bilateral ICA, MCA, and ACA territories. The third study (right column) shows day 23 after rupture with improved rCBF and relief of vasospasm. The figure is adapted from [51].
