The radiological dose-sparing cascade provided by technical and cultural upgrading in four critical areas of cardiology: Myocardial Perfusion Imaging (MPI, from thallium to sestamibi tracers, from standard to triple-headed gamma camera, and from gamma camera to PET imaging with N-13 ammonia), MDCT (Multi-Detector Computed Tomography, from retrospective to prospective triggered techniques with dose modulation), interventional cardiology (with 90% dose reduction simply achieved through radioprotection training) and cardiac radiofrequency ablation (moving from standard fluoroscopy to near-zero exposure with non-fluoroscopy navigation techniques).
