A Study to Evaluate Photon Counting Detector CT Utility in Identifying Acute Wrist Fractures.


About this study

The purpose of this study is to examine the ability of PCD-CT to (1) display subtle fractures of the wrist using the system’s increased spatial resolution compared to conventional wrist CT and MR; and (2)  evaluate the ability of PCD-CT with virtual non-calcium images to identify bone marrow edema at acute fracture sites.
