Outlining Some Current Strategies for Dose Reduction
| Dose reduction strategy | Approximated dose reduction |
| Appropriate patient selection | Significant reduction |
| Stress-only SPECT imaging | Significant reduction |
| Solid-state cameras | 50% (11,12) |
| PET (3-dimensional mode of operation with lutetium oxyorthosilicate system) | Significant reduction |
| Iterative reconstruction | 50%–75% (13–16) |
| Multiple detector systems (17) | Significant reduction |
| Resolution recovery software | Significant reduction |
| Collimator (general-purpose collimator acquisition) | 50% (18) |
| Collimators for cardiac imaging (19,20) | Minor |
| Continuous acquisitions | 5% (21) |
| Voiding | 16.9% |
