Pregnancy - Special Patient and Personnel Considerations

According to the study, how common is it for a pregnant woman to undergo an MRI?. 1 in 50 pregnancies. 1 in 100 pregnancies. 1 in 250 pregnancies. 1 in 1,000 pregnancies.

What did the study conclude about the risk of birth defects or cancer for MRIs performed in the first trimester?. There was no increased risk compared to those who did not have an MRI. There was a significant 5% increase in risk. Risk increased only if the MRI lasted longer than 30 minutes. Risk increased only in multiple-birth pregnancies (twins/triplets).

Up to what maximum age were the children followed in this study to monitor adverse outcomes?. 1 year old. 4 years old. 10 years old. 18 years old.

When gadolinium contrast was used at any point during pregnancy, what slight increase in risk was noted?. Gestational diabetes. Stillbirth or neonatal death. Premature labor. Maternal high blood pressure.

How many pregnancies involving first-trimester MRIs were analyzed in this population-based study?. Approximately 1,700. Approximately 500. Approximately 5,000. Over 10,000.

Nephrogenic Systemic Fibrosis (NSF) in children exposed to gadolinium in utero was found to be: Very common. Occurring in 10% of cases. Very rare. Non-existent in the study group.

For which group of conditions did the study see a "slightly higher" but nonspecific outcome in children exposed to gadolinium?. Cognitive and developmental delays. Vision and hearing loss. Rheumatological and dermatological conditions. Respiratory and cardiac issues.

Why did the researcher express caution regarding the findings of rheumatological/dermatological conditions?. The sample size was too small to be meaningful. It's unclear if gadolinium caused the conditions or if they were part of a "broad array" of unrelated issues. The conditions only appeared in children born in the summer. The conditions disappeared by age two.

When imaging deep structures like the brain or spinal cord in a pregnant woman, the study suggests MRI is a safe alternative to: Ultrasound. CT scan. X-ray. Physical palpation.

What is the general conclusion regarding non-contrast (no gadolinium) MRI in the first trimester?. It should be avoided at all costs. It is only safe after the 20th week of pregnancy. It provides excellent images and a "sense of safety" with no noted adverse outcomes. It is less safe than a CT scan.
