Correct answer is - I won't be extremely worried about any of these
Option 1: Fetal radiation doses below 50 mGy is not known to cause fetal harm irrespective of gestational age (see reference below for details). A routine CECT single phase abdomen study usually involves only 10-12 mGy of exposure.
Option 2: Contrast-induced nephropathy is not a concern, as barely any contrast gets excreted into the fetus.
Option 3: Initially thought to be a concern, multiple studies have shown that iodine in the IV contrast media does not cause any thyroid issues in the fetus. However, the mother should be advised to do a neonatal thyroid screen as this is routine screening protocol for all infants, irrespective of whether they have been exposed to CT contrast or not!
