Dedicated cardiac camera reduces radiation dose, acquisition time

01/20/2013 | MolecularImaging.net

Researchers have developed a dedicated SPECT/MPI cardiac camera that has the potential to reduce imaging acquisition time and radiation dose, according to findings from a simulation study published in the Journal of Nuclear Medicine. Researchers, using reframed list-mode raw data, found that 1 million counts yielded images comparable to 8 million counts. The study involved 79 consecutive patients referred for a rest-stress MPI. Researchers are calling for similar simulation trials to test the feasibility of other dedicated cardiac modalities.
