From: Optimizing integrated imaging service delivery by tier in low-resource health systems
Recommended imaging quality management and oversight resource strategy by health system tier. Higher levels on the pyramid denote increasing complexity and additional requirement for more sophisticated, specialized quality management and oversight. Green arrows indicate added quality and oversight needed at the next highest tier (QA = Quality assurance; QI = quality improvement; M&E = monitoring and evaluation; MRI = magnetic resonance imaging; NM = nuclear medicine; IR = interventional radiology)
