PCCT visualizes pulmonary embolism at reduced radiation dose

Photon-counting CT (PCCT) effectively visualizes pulmonary embolism (PE) and reduces radiation dose by 48% compared with traditional CT, according to research presented November 27 at the RSNA meeting. "[PCCT] ensures confident depiction of acute PE with spectral imaging available at low radiation dose in all patient categories," said presenter Martine Remy-Jardin, MD, PhD, of the University Centre of Lille in France. Remy-Jardin and colleagues conducted a study that compared performance of traditional CT to PCCT for diagnosing acute PE. The research included a group of patients referred for suspicion of acute pulmonary embolism who underwent a chest CT angiographic (CTA) exam with a traditional CT system (158 patients) and a second group that underwent CTA with a PCCT device (172 patients). Group 1 patients underwent the exam with one of two scanning options depending on their respiratory status: a dual-energy protocol when a six-second breath hold was possible (Group 1a, 105 individuals), or a high-pitch, single-energy protocol when the patient was short of breath (Group 1b, 53 individuals). All patients in Group 2 were scanned with a multienergy protocol. .tg {border-collapse:collapse;border-spacing:0;} .tg td{border-color:black;border-style:solid;border-width:1px;font-family:Arial, sans-serif;font-size:14px; overflow:hidden;padding:10px 5px;word-break:normal;} .tg th{border-color:black;border-style:solid;border-width:1px;font-family:Arial, sans-serif;font-size:14px;...
