- AI-Assisted Summarization of Radiologic Reports: Evaluating GPT3davinci, BARTcnn, LongT5booksum, LEDbooksum, LEDlegal, and LEDclinical
This study quantitatively evaluated the performance of natural language processing models using real, longitudinal brain aneurysm imaging reports to objectively understand the strength and weakness of these new technologies.
- Discrimination of Hemorrhage and Contrast Media in a Head Phantom on Photon-Counting Detector CT Data
Photon-counting detector CT acquires spectral information that allows for material differentiation. CT scan can be separated into the attenuation resulting from remaining iodine and soft tissue, generating contrast media maps and virtual noncontrast series. In this study, the authors demonstrated that PCD-CT can reliably differentiate between blood and iodine and accurately determine several iodine concentrations in an anthropomorphic head phantom.
