Predictors of initial 18F-fluorodeoxyglucose-positron emission tomography indication among patients with colorectal cancer

Abstract

Higher utilization of F-FDG-PET may be appropriate among patients referred for a number of indications including: initial staging, particularly among those with higher-stage disease; suspected recurrence on conventional imaging among patients with lower-stage disease; and suspected recurrence more than 2 years after diagnosis. Further research is needed to verify these findings.

Predictors of CT Colonography Utilization Among Asymptomatic Medicare Beneficiaries

“…36 Although CTC can be performed using any multi detector CT, it is possible that access to CTC for minority patients was restricted during this relatively early stage of adoption; similar to discrepant adoption of other types of new imaging technology among non-white patients. 37,38 Given the higher incidence and mortality from colorectal cancer among black patients and lower rates of screening in minority patients overall, this cohort could benefit most through CTC. 2,39 However, further research is needed on the factors contributing to this disparity.…”
