An ultrafast, 320-detector computed tomography (CT) scanner that shows both anatomy within coronary arteries and blood flow can accurately sort out which people need – or don’t need – an invasive procedure to identify coronary blockages, according to the CORE 320 international study. The study was conducted with 381 patients at 16 hospitals in eight countries. The researcher say that 91 percent of those in whom the CT scan ruled out blockages would not have required invasive treatment.
A position paper published in the European Heart Journal urges reduced radiation exposure for cardiology patients.

Topics in Radiography discusses what radiologist should know about using Digital Radiography equipment with the primary goals of providing optimum exposure to the image receptor, reducing patient dose, and producing high quality images for interpretation. While every DR system is different, this discussion focuses on the basic things inherent to every digital radiography system so that no matter what equipment you are using.
