Question 1

According to ACR guidelines, what is the recommended policy for pregnant healthcare personnel regarding access to the MRI scan room (Zone IV)?

Accepted Answer

They are permitted in Zone IV but should exit the room during active data acquisition.

Answer

They are prohibited from entering Zone IV at all times.

Answer

They may only enter Zone IV if the static magnetic field is less than 1.5T.

Answer

They must wear a lead apron and a dosimeter while in Zone IV.

Question 2

What is the primary reason for caution when considering an MRI for a patient in the first trimester of pregnancy?

Accepted Answer

This is the period of major organogenesis, making the fetus theoretically more vulnerable.

Answer

The static magnetic field is known to be teratogenic.

Answer

The fetus is most sensitive to acoustic noise during this period.

Answer

Gadolinium-based contrast agents are most likely to cross the placenta in the first trimester.

Question 3

Under which circumstance is the administration of a gadolinium-based contrast agent (GBCA) to a pregnant patient generally considered?

Answer

A letter of medical necessity from the referring physician.

Answer

A report from a prior ultrasound confirming fetal viability.

Question 5

The primary safety concerns for the fetus during an MRI examination are related to which two physical phenomena?

Accepted Answer

RF energy deposition and acoustic noise.

Answer

Static magnetic field and cryogen exposure.

Answer

The missile effect and patient anxiety.

Answer

Time-varying magnetic fields and static magnetic field.

Question 6

If a healthcare worker discovers they are pregnant, what is the most appropriate first step regarding their MRI work duties?

Accepted Answer

Voluntarily declare the pregnancy to their employer/MRSO.
