Image quality by standard dual-detector SPECT (S-SPECT) cameras and by the DNM camera

	Rest S-SPECT (n = 330)	Rest DNM (n = 330)	Stress S-SPECT (n = 330)	Stress DNM (n = 330)
Excellent	232 (70.3%)*	275 (83.3%)*	224 (67.9%)**	282 (85.5%)**
Adequate	94 (28.5%)¶	47 (14.2%)¶	105 (31.8%)¶¶	41 (12.4%)¶¶
Suboptimal	4 (1.2%)	8 (2.4%)	1 (0.3%)	7 (2.1%)

There were no significant differences in the rate of suboptimal quality studies at rest or stress between S-SPECT and DNM. For all other comparisons (*,**, ¶, ¶¶), P < .05.
