Does myocardial perfusion scintigraphy with IQ∙SPECT technology provide prognostic value in patients with suspected or known coronary artery disease?
Background: IQ∙SPECT is a collimator design coupled with a cardio-centric acquisition orbit and specific reconstruction algorithm that increases camera efficiency. However, there is no prognostic data derived from IQ∙SPECT exams. Objectives: To evaluate the prognostic value of IQ∙SPECT myocardial perfusion scintigraphy (MPS) in patients with suspected or known coronary artery disease (CAD). Methods: The study population consisted of 734 consecutive patients with suspected or known CAD submitted to MPS with IQ∙SPECT. Adequate follow-up was obtained in 625 patients. We ...
