A pregnant woman at 10 weeks needs imaging for abdominal pain. Which approach follows IR(ME)R principles?
Answer and explanation
Correct answer: D. Choose ultrasound or MRI where possible
- Step 1: Ionising radiation exposure must be justified and optimised, with extra care for the fetus. Step 2. Ultrasound and MRI have no ionising radiation and are first-line choices, but necessary imaging is not withheld if needed for the mother's health. Answer: Choose ultrasound or MRI where possible. Why not the others: CT without thought of the fetus breaches justification. Refusing all imaging may harm the mother. Routine X-rays are not justified.
