To evaluate the effectiveness of structured nuclear cardiology training. the reproducibility and accuracy of image interpretation by nuclear cardiology faculty and senior cardiology fellows were compared. The reproducibility and accuracy of 3 faculty and 3 trainees with 6 months training following Nuclear Regulatory Commission/American College of Cardiology guidelines were assessed using 138 exercise Tc-99m Sestamibi SPECT studies. Studies were randomly selected and included patients with<5% likelihood of CAD as well as patients with angiographically demonstrated single and multivessel disease. Studies were interpreted twice by each reader without knowledge of clinical or exercise data. Each reader classified perfusion as normal (N) or abnormal (AB). AB perfusion was further classified as fixed (F) or ischemic (I). Reproducibility was compared with respect to first order (N vs AB) and second order (N vs F vs I) intra and inter observer agreement and assessed using percent agreement (%) and Cohen's kappa. Accuracy was assessed using sensitivity and normalcy rate and compared using percent agreement and Cohen's kappa.TraineesFaculty%kappa%kappaReproducibilityFirst orderIntra:890.78920.82inter:800.59860.71*Second orderintra:810.66870.74*inter:690.46820.64*AccuracySensitivity8287Normalcy Rate8589% agreement/kappa83063870.73**p<0.05 compared with trainees |
