A new trimodality imaging system, combining PET, CT and MRI scans, could improve patient safety and afford better detection of some cancers, according to a DOTMed report.
GE Healthcare, which is trialing the trimodality system in Hong Kong, says its treatment of soft tissue could make it superior in detecting certain cancers and its use of MRI for attenuation correction of PET scans would not require patient exposure to ionizing radiation from a CT scanner.
Bimodality imaging systems are already in use. In June, Siemens Healthcare received FDA approval for its Biograph mMR, an integrated PET-MR system. And Philips Healthcare has received European marketing approval for its Ingenuity TF PET-MR, featuring two separate units attached by a rotating patients' table.
