Lesson 1Reasons and timing for follow-up scans and use of ultrasound or MRI in unclear or pregnant patientsThis lesson reviews when to redo scans, how patient changes guide scan type, and roles of ultrasound and MRI in unclear, child, or pregnant cases, balancing benefits, radiation, and contrast safety in Botswana.
Patient signs needing repeat scansUltrasound methods for suspected appendicitisMRI plans in pregnancy and childrenBalancing radiation risks and scan valueWhen CT is still needed in pregnancyLesson 2Antibiotic and surgery prep linked to scan results (e.g., spread of infection, abscess)This lesson links CT results with antibiotic and surgery plans, covering infection spread, abscess size, sepsis risk, surgery timing, prevention choices, and treatment length based on scan severity in local care.
