PET/MRI rules out tau protein in late-life depression
A PET/MRI study has provided insights into the neurobiology of late-life depression, finding tau protein is not involved in the condition.

Coronal and axial slice of the average cortical F-18 MK-6240 SUVR [standard uptake value ratio] image for each study population. SUVR images were corrected for partial volume effects and masked with the gray matter mask used for volume of interest delineation. Overall tau accumulation is comparable between the late-life depression (LLD, middle column) and non-depressed cognitively unimpaired comparison (HC, left column) groups, while abnormal tau accumulation, which is most pronounced in the mesial temporal lobe, can be seen in the mild cognitive impairment due to Alzheimer's disease group (right column).

Tau PET identifies grey matter atrophy in retired athletes
Flortaucipir PET imaging is able to identify neuropathological brain changes in retired contact sport athletes at risk of neurodegeneration.

Example of the flortaucipir tau-PET signal and distribution of low grey matter volume in a single former athlete. Spatial maps of the flortaucipir tau-PET standardized update value (SUVR) (top) and the reduced grey matter volumes showed in blue and defined as voxels with a w-score of >1.5 below the mean (bottom) in a single former athlete.

FAPI-SPECT reveals damage to myocardium after heart attack
Technetium-99m (Tc-99m) FAPI-SPECT shows promise as a tool for assessing cellular and structural changes in the myocardium after heart attack.
July 16, 2024
Emergency percutaneous coronary intervention images, Tc-99m MIBI perfusion images and Tc-99m FAPI images of STEMI patients. In STEMI patients, there is a localized yet inhomogeneous uptake of Tc-99m FAPI. Notably, the extent of Tc-99m FAPI uptake significantly surpasses the area of perfusion defects. Despite similarities in coronary artery lesions (culprit vessels identified as the left anterior descending artery in image A and the right coronary artery in image B, white arrows), and comparable myocardial perfusion impairment, patients with larger Tc-99m FAPI uptake areas exhibit ventricular remodeling.
