PCCT offers better cardiovascular imaging quality in infants with suspected congenital heart defects

A new advanced form of CT imaging called photon-counting computed tomography (PCCT) offers better cardiovascular imaging quality at a similar radiation dose compared to dual-source CT (DSCT) in infants with suspected cardiac heart defects, according to a study published in Radiology, a journal of the Radiological Society of North America.
