U.S., Aug. 7 -- ClinicalTrials.gov registry received information related to the study (NCT07748923) titled 'Photon-Counting CT for Detection of Small Gastrointestinal Lesions' on July 12.
Brief Summary: This comparative matched-cohort study aims to evaluate the diagnostic performance of contrast-enhanced photon-counting computed tomography (PCCT) for detecting small gastrointestinal lesions compared with energy-integrating detector dual-energy computed tomography (DECT). The study includes a prospectively enrolled PCCT cohort and a retrospectively identified DECT cohort. Endoscopy with histopathology serves as the reference standard. Primary evaluation focuses on lesion detection, with additional assessment of lesion characterization, imag...
