According to LLc, diffuse hyperemia can be detected by calculating the early gadolinium enhancement ratio (EGEr): endocardial and epicardial contours should be traced on both pre- and post-contrast images, and a reference region of interest (ROI) should be placed on the skeletal muscle located within the same slice.

Subcortical white matter can be used as a reference region for quantitative analysis of [F]FDDNP with the Logan method which allows more accurate and less biased binding estimates, but a population efflux rate constant has to be determined a priori.

We chose the thigh muscle as a reference region to validate the action of PIO.

However, PET imaging of the monkey and human brains with [11C]MK-8278 employed the pons as a reference region to estimate the occupancy of H3Rs by an antagonist/inverse agonist, MK-0249 [130 30].
