Representative PET, SPECT, and scintigraphy findings. Left ventricular transaxial slices (vertical long axis, horizontal long axis) and polar map presentation (17-segment model) of, respectively, cardiac 18F-FDG PET, 123I-mIBG SPECT, and perfusion scintigraphy performed during acute phase and follow-up in a patient with aneurysmal subarachnoid hemorrhage. We observed that the uptake of both 18F-FDG and 123I-mIBG were markedly reduced during the acute phase. The uptake of 18F-FDG was normalized two months later. The uptake of 123I-mIBG was still impaired six months after the onset of symptomatology. 123I-mIBG, 123I-meta-iodobenzylguanidine; 18F-FDG PET, 18F-fluorodesoxyglucose positron emission tomography; PET, positron emission tomography; SPECT, single-photon emission computed tomography.
