MEDRAD will offer RSNA 2010 attendees hands-on demonstrations of personalized-protocol software that individualizes CT Pulmonary Angiography (CTPA) contrast dosing, and has proven to increase the percentage of diagnostic-quality studies to rule out Pulmonary Embolism (PE) when compared with an institution’s standard protocol (at a slightly higher contrast dose than a standard protocol of 80 ml) — potentially obviating the need to rescan the patient.
Diagnosis with a high degree of certainty is critical to the safety of patients with suspected PE, yet can be inhibited by imaging complexities associated with these studies. PE, a blockage of the pulmonary artery or one of its branches due to a blood clot or other thrombus, results in as many as 50,000 deaths a year, most of which occur in the first few hours.
MEDRAD’s P3T PA (Pulmonary Angiography) software enables increased diagnostic quality studies by fitting into the established CTPA workflow and making consistent administration of personalized dosing practical. The firm said the clinically validated P3T algorithm tailors each patient’s contrast protocol based on technologists’ touch-screen responses to unique clinical concerns, study requirements, and the scanning equipment used.
“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,” said Joan Lacomis M.D., Clinical Professor Radiology, The University of Pittsburgh Medical Center.
Albany Medical Center Researchers concluded that suboptimal emergency department CTPA interpretations to rule out PE can substantially impact healthcare resource utilization and increase healthcare costs. Thirty percent of their CTPA studies showed suboptimal results, and these patients were subjected to additional imaging studies or received medical therapy. In some cases, patients were admitted to the hospital for further PE diagnosis considerations. None of the additional treatments or imaging modalities yielded a diagnosis of PE.
“We’re enabling increased diagnostic-quality studies at a point when timely and accurate diagnosis is critical,” said Anthony Cinalli, executive director of MEDRAD Radiology. “The software makes applying the science of personalizing patient dose practical at the point of care, and offers the potential to significantly impact healthcare utilization.”
In addition to quality improvements, the software offers flexibility and efficiency in administering personalized contrast dose for CT angiography for multiple regions of the cardio-pulmonary vasculature, especially when operating higher-speed scanners. The P3T line also includes cardiac and abdominal CT software versions that automate each patient’s optimal contrast dose for studies addressing these areas of the anatomy.
