Abstract:Purpose:
A prospective clinical study was conducted to assess whether sub‐mSv cerebral CT perfusion (CTP) imaging can be achieved using the Prior Image Constrained Compressed Sensing (PICSS) reconstruction algorithm.
Methods:
Following a standard dose (SD) CTP acquisition, 31 patients (median age, 62 years; 15 M/16 F; median BMI, 27) underwent an additional reduced dose (RD) CTP acquisition at 20% of the standard dose level. Several algorithms (PICCS, ASIR, and FBP) were used to reconstruct CTP source images o… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
