TL;DR: It is suggested that for solid pulmonary lesions with low 18F-FDGPET uptake, semiquantitative approaches do not improve the accuracy of 18F -FDG PET over that obtained with visual analysis, and intra- and interobserver variabilities indicated that visual and SUV analyses were quite reproducible, whereas CR analysis was poorly reproduced.

TL;DR: It is found that tumor cells expressed higher levels of cytosolic acetyl‐CoA synthetase (ACSS2) under hypoxia than normoxia, which indicates that ACSS2 is a bi‐directional enzyme in tumor cells and that AC SS2 might play a buffering role in tumor acetyl-CoA/acetate metabolism.

TL;DR: ER expression and glucose metabolism of uterine tumors measured by using PET showed opposite tendencies, and PET studies with both FES and FDG could provide pathophysiologic information for the differential diagnosis of uterusine tumors.

TL;DR: This preliminary study revealed that ACE PET is a promising tracer for the grading of brain glioma.

TL;DR: Endometrial carcinoma reduces estrogen dependency with accelerated glucose metabolism as it progresses to a higher stage or grade through a new index of the 18F-FDG–to–18F-FES ratio, which is considered the most informative index reflecting tumor aggressiveness.
