AI Article Synopsis
- - The study compared the accuracy of left ventricular systolic performance measurements using a new imaging method called cadmium-zinc-telluride (CZT) semiconductor cameras with traditional methods like echocardiography (echo) and cardiac magnetic resonance (CMR) imaging in patients with myocardial infarction.
- - 60 patients participated, and all of them underwent echo, CZT-SPECT, and CMR about 6 weeks after their heart attack, focusing on how well the measurements matched, especially the left ventricular ejection fraction (LVEF).
- - The results showed strong agreement between CZT-SPECT and CMR (r = .79) as well as between CZT-SPECT and echo, indicating that CZ
Article Abstract
Background: There are paucity of data comparing measurements of left ventricular systolic performance using cadmium-zinc-telluride (CZT) semiconductor cameras with other imaging modalities. This study compared the new system with echocardiography (echo) and cardiac magnetic resonance (CMR) imaging.
Methods: 60 Patients presenting with ST-elevated myocardial infarction (MI) were included. Each patient underwent echo, myocardial perfusion imaging using Spectrum Dynamics D-SPECT(r) (CZT-SPECT), and CMR 6 weeks after MI. The primary endpoint was the agreement between CZT-SPECT and CMR for left ventricular ejection fraction (LVEF) measurement.
Results: 48 of the 60 patients underwent all 3 studies (echo, CMR, and CZT-SPECT) 40 days after admission. CZT-SPECT and CMR LVEF were well correlated (r = .79, P < .0001), as well as CZT-SPECT vs echo and CMR vs echo (r = .79 and .84, respectively, P < .0001). The segmental LV wall thickening and wall motion also showed good concordance between three techniques.
Conclusions: CZT-SPECT is reliable for LVEF measurement.
