The purpose of this study was to investigate if a novel parameter, the stress-to-rest ratio of the signal-to-noise ratio (RSNR) obtained with a cadmium zinc telluride (CZT) SPECT scanner, could be used to distinguish triple-vessel disease (TVD) patients.
Methods.
One hundred and two patients with suspected coronary artery disease were retrospectively involved.
Each subject underwent a Tl-201 SPECT scan and subsequent coronary angiography.
Subjects were separated into TVD (n=41) and control (n=61) groups based on coronary angiography results using 50% as the stenosis cutoff.
The RSNR was calculated by dividing the stress signal-to-noise ratio (SNR) by the rest SNR.
Summed scores were calculated using quantitative perfusion SPECT (QPS) for all subjects.
Results.
The RSNR in the TVD group was found to be significantly lower than that in the control group (0.83 ± 0.15 and 1.06 ± 0.17, resp.; P<0.01).
Receiver-operating characteristic (ROC) analysis showed that RSNR can detect TVD more accurately than the summed difference score with higher sensitivity (85% versus 68%), higher specificity (90% versus 72%), and higher accuracy (88% versus 71%).
Conclusion.
The RSNR may serve as a useful index to assist the diagnosis of TVD when a fully automatic quantification method is used in CZT-based SPECT studies.
