Medrad demonstrated its P3T Cardiac CT Injection Software, shared results of a recent study of personalized patient injection protocols and showed potential advances of its P3T products at the 94th Radiological Society of North America (RSNA) annual meeting in Chicago.
Personalized patient injection protocols are showing promise, according to a recent University of Pittsburgh Medical Center (UPMC) study, which documented that contrast injection protocols personalized to patient-specific parameters of its test group resulted in a higher percentage of exams that could be classified as “diagnostic, without limitations” to rule out pulmonary embolism than resulted from non-personalized standard injection protocols. The personalized patient protocols provided better contrast enhancement of the pulmonary arteries in the study group as well.
Joan Lacomis, MD, radiologist at UPMC and co-author of the study, said that achieving “a diagnostic CT image for pulmonary embolism, without limitations, helps the hospital and emergency department in a number of important ways - with efficiency, patient care and cost savings. Achieving high quality images for a higher percentage of studies multiplies these benefits and our research indicates that personalizing the contrast injection protocol to patient-specific parameters is a promising approach.”
Medrad showed its P3T Cardiac and P3T Abdomen patient specific protocol generators and hinted that future modules could expand to neurological, pulmonary and angiography studies.
The company also launched Medrad Informatics Solution, which records injection data. Reporting functionality will be available early in 2009. The company plans to add the ability to push DICOM data to PACS later in 2009.
Medrad announced FDA 510(k) clearance for Intego, an FDG Infusion System for PET/CT. The system automates and controls the FDG delivery process, enabling the provider to administer FDG at any time throughout the day. The Intego System extracts a patient dose from a multi-dose vial and delivers it directly to the patient, eliminating manual dose preparation and handling, and the corresponding radiation exposure to the technologist.
With the Intego System’s dose-on-demand capability, the prescribed dose can be delivered when the patient and technologist are ready, enabling technologists to respond to schedule changes, patient delays and add-on patients. Real-time dose information, an integrated ionization chamber and an optional weight-based dose calculation allow the provider to customize each patient’s dose. Safety features include a tungsten multi-dose vial shield, a lead-lined mobile cart and an automated saline flush to remove residual FDG from the line after each infusion.
