CT radiomics improves management of bile duct cancer
By Abraham Kim
Researchers from China have developed a radiomics model that can determine the malignancy of lymph node metastases in patients with bile duct cancer by analyzing features on CT scans, according to an article recently published online in Radiology. They believe the model can predict the survival rate of patients.

Is CT or US better for diagnosing gallbladder infection?
By Abraham Kim
CT was found to be considerably more accurate than ultrasound at identifying acute cholecystitis in a new study, published in the August issue of the American Journal of Roentgenology. But is that enough evidence for CT to oust ultrasound as the imaging modality of choice? Probably not, say researchers from New Mexico.
