Lesson 1Reasons and timing for follow-up scans and using ultrasound or MRI in unclear or pregnant patientsThis part reviews when to repeat scans, how patient changes guide method choice, and roles of ultrasound and MRI in unclear, child, and pregnant patients, balancing scan value, radiation, and contrast safety.
