NORTH BILLERICA, Mass.--(BUSINESS WIRE)--Lantheus Medical Imaging, Inc., a worldwide leader in diagnostic medical imaging, today announced preliminary Phase 2 data describing the methodology used to define an imaging protocol for a one-day rest-stress myocardial perfusion imaging test using its novel investigational PET imaging agent flurpiridaz F 18 injection (formerly known as BMS747158). Flurpiridaz F 18 injection is in development for use with Positron Emission Tomography (PET) for myocardial perfusion imaging (MPI) to detect coronary artery disease. Data suggest that the uptake properties of flurpiridaz F 18 injection make it possible to allow for a relatively low dosing ratio and a delay of between 30 minutes and one hour between rest and stress injections, depending on the mode of stress used.
