No, it is generally not recommended to wear an underwire bra for a lung CT scan.
For an accurate lung CT scan, it's crucial to minimize anything that could interfere with the imaging process. Metals, in particular, can cause artifacts on the scan, making it difficult for radiologists to get a clear view of your lungs.
Why Metal is a Concern in CT Scans
Computed Tomography (CT) scans utilize X-rays to create detailed cross-sectional images of the inside of your body. When X-rays encounter metal, they can scatter or be absorbed differently than body tissues. This can lead to bright streaks or distortions on the images, known as artifacts. In a lung CT scan, these artifacts can obscure important details within the chest area, potentially affecting the diagnostic quality and the ability to detect subtle abnormalities.
Items to Avoid for Your Scan
To ensure the clearest possible images and prevent interference, you will typically be asked to remove any items containing metal that are within the scan field. This includes:
- Underwire Bras: The metal underwire is a primary concern for CT scans of the chest and lung area due to its direct proximity to the imaging region.
- Jewelry: All forms of jewelry, such as necklaces, earrings, rings, watches, and body piercings, should be removed.
- Glasses: If they have metal frames, they should be taken off.
- Hearing Aids and Dentures: Depending on their composition and the specific area being scanned, you may be asked to remove these.
- Clothing with Metal Components: Apparel containing metal buttons, zippers, snaps, or embellishments (like some jeans or shirts) should also be avoided.
Preparing for Your Lung CT Scan
To ensure a smooth and effective scan, consider these practical tips:
- Choose Metal-Free Attire: Opt for comfortable, loose-fitting clothing made from soft fabrics like cotton, fleece, or activewear materials that do not contain any metal elements. Examples include sweatpants, t-shirts, or non-underwire sports bras.
- Leave Valuables at Home: It's often easiest to leave all jewelry and other metal accessories at home before your appointment.
- Expect a Gown: If your clothing contains too much metal or is deemed unsuitable for the scan, the imaging center will provide you with a hospital gown to change into. This ensures there's no metallic interference from your clothing during the procedure.
- Communicate with Staff: If you have any questions or concerns about specific clothing items, medical implants, or any other preparations, do not hesitate to ask the CT technologist or medical staff before your scan begins.
By adhering to these guidelines, you help ensure that the CT scan provides the clearest and most accurate images possible for your medical evaluation.
