A CT scan, commonly referred to as a computed tomography scan, is a medical imaging procedure that utilizes a computer to compile multiple X-ray images, resulting in detailed cross-sectional and three-dimensional views of internal organs and structures within the body. If you’re interested in learning more about undergoing X-rays during pregnancy, you can find additional information on the topic.
Purpose of a CT Scan
CT scans are typically performed to assess internal structures within the body. Some common issues that a CT scan can help identify include:
- Head: Detection of blood clots, skull fractures, tumors, and infections.
- Spine: Identification of vertebral fractures and herniated discs.
- Chest: Evaluation of heart anomalies, lung problems, and infections.
- Abdomen: Investigation of tumors, infections, abnormal anatomy, appendicitis, and cysts.
Risks Associated with CT Scans During Pregnancy
Undergoing a CT scan during pregnancy involves exposure to radiation that is slightly higher than that of standard X-rays. The effective radiation dose from a CT scan is approximately 10 mSv, which is comparable to the amount of background radiation a person typically receives from natural sources, like the sun, over a span of three years.
However, the potential benefits of obtaining a precise diagnosis may outweigh the risks linked to radiation exposure. The American College of Radiology states that no imaging procedure using X-rays delivers a radiation dose significant enough to cause adverse effects on a developing embryo or fetus. In general, CT scans are discouraged during pregnancy unless the advantages clearly exceed the possible risks.
A common concern is related to adverse reactions to the contrast dye used in some CT scans. Reactions may include itching, hives, nausea, or rapid breathing, although severe reactions such as difficulty breathing are rare. It’s crucial to inform your healthcare provider that you are pregnant before undergoing any medical tests or procedures.
CT Scans and Breastfeeding
For breastfeeding mothers, it’s recommended to wait 24 to 48 hours after receiving a contrast agent injection before resuming breastfeeding. The dye can be transmitted through breast milk to the infant.

In conclusion, while CT scans can be invaluable for diagnosing various conditions, their use during pregnancy should be carefully considered. The potential radiation exposure and its effects on a developing fetus must be weighed against the necessity of obtaining a clear diagnosis. Always discuss your concerns and options with your healthcare provider.
