Background Angiotensin converting enzyme 2 (ACE2), a target of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), demonstrates its highest surface expression in the lung, small bowel, an...

By using the differential attenuation of tissues and materials at different x-ray energies, multienergy CT allows distinction of tissues and materials beyond that possible with conventional CT. Multienergy CT involves acquisition of two or more CT measurements with distinct energy spectra. Using the differential attenuation of tissues and materials at different x-ray energies, multienergy...

Dual-energy CT is a tremendous innovation in CT technology that allows creation of acquisitions at more than one energy spectrum and provides improved lesion detection and characterization, superio... Dual-energy CT (DECT) is a tremendous innovation in CT technology that allows creation of numerous imaging datasets by enabling discrete acquisitions at more than one energy level. The wide range o...

GPT-4 enabled near-perfect creation of pancreatic ductal adenocarcinoma synoptic reports from original reports and accurate resectability categorization using chain-of-thought prompting, which improved surgeon accuracy and efficiency in interpreting reports for resectability categorization.

The CT/MRI Liver Imaging Reporting and Data System version 2024 Treatment Response Assessment (TRA) algorithm now has two independent cores with tailored TRA criteria after nonradiation or radiation-based liver-directed therapy and incorporates MRI ancillary features (diffusion restriction and mild to moderate T2 hyperintensity).
