From: Optimizing integrated imaging service delivery by tier in low-resource health systems
Recommended imaging technology strategy by health system tier. Higher levels on the pyramid denote increasing complexity. For each tier, red indicates a requirement for higher complexity of technology while blue indicates lower complexity of technology. (POCUS = Point of Care ultrasound; NR-U = non-radiologist ultrasound; CT = computed tomography; MRI = magnetic resonance imaging; FL = fluoroscopy; B-IR = BASIC Interventional Radiology; ABI = advanced breast imaging; PET = positron emission tomography; NM = nuclear medicine; subspecialized IR = neurointerventional)
