Detecting Triple-Vessel Disease with Cadmium Zinc Telluride-Based Single-Photon Emission Computed Tomography Using the Intensity Signal-to-Noise Ratio between Rest and Stress Studies

Figure 3

The stress MPI images of a representative TVD case, a 64-year-old woman, which showed uniform tracer uptake in the myocardium. From top to down, the original axial views of the stress acquisition, the segmented axial views of the stress acquisition, and the polar maps were shown. SSS, SRS, and SDS are 2, 0, and 2, respectively. The RSNR was 0.91, indicating a low tracer uptake in the stress study and high possibility of present TVD. The CAG identified stenosis of 61% in the LAD, 69% in the LCX, and 62% in the RCA.
