Previously we shared that JAMA Internal Medicine published a study that CT scans could be responsible for up to 5% of new cancer cases each year. That is a sobering number if you think about it: One in 20 new cancer cases could be linked to diagnostic radiation. To read the previous article about this, click here. This week, we are exploring recovery steps for those who may need a CT scan, as well as alternatives to consider with your provider before undergoing one.
Recovery Steps After a CT Scan
The Computed Tomography scan, or CT scan, is a medical imaging technique using X-rays to capture detailed images of cross-sections of the body. Sometimes, contrast dye is also used to improve the images. If you undergo a CT scan, your body will experience oxidative stress and, if applicable, need to detoxify the contrast dye. Here are some steps you can take after a CT scan to support your body:
- Drink plenty of water to help eliminate contrast dye and support overall detoxification.
- Antioxidants are a powerful way to repair oxidative stress from radiation exposure, neutralizing free radicals and offering anti-inflammatory properties. The most effective for this purpose are Vitamin C & E, Glutathione, and Curcumin.
- Using Magnesium to support cellular repair mechanisms and Zinc to support DNA repair and immune function are ideal mineral resources.
- Several foods offer radiation protection and can be eaten before and after a CT scan to support the body. Algae such as spirulina or chlorella contain compounds that may reduce radiation damage. Cruciferous vegetables like broccoli, kale, and Brussels sprouts are high in sulforaphane, which supports detoxification. Berries are rich in polyphenols and other antioxidants.
- It is important to support detoxification pathways to clear the contrast dye. Sauna, infrared therapy, Epsom salt baths, and binders such as activated charcoal, bentonite clay all promote toxin/toxicant elimination.
Alternatives to CT Scans
- Magnetic Resonance Imaging, or MRI, uses magnetic fields and radio waves, so it is a radiation-free option best suited for soft tissues, brain, spinal cord, joints, ligaments, and blood vessels.
- Ultrasound uses sound waves, so it is another radiation-free option. Ultrasound is best for abdominal organs, blood flow, musculoskeletal issues, and fetal imaging.
- Digital X-rays impose significantly less radiation exposure compared to CT scans and are useful for bone fractures, dental issues, and chest imaging.
- Low-Dose CT scans are significantly lower than standard CT scans and can be useful where CT imaging is unavoidable, but dose reduction is possible.
- Functional imaging, most often Positron Emission Tomography [PET], is frequently combined with CT or MRI for detailed imaging, though it involves some radiation exposure. Magnetic Particle Imaging [MPI] is in the experimental stages and is radiation-free.
- Photoacoustic Imaging [PAI] uses sound waves generated by laser pulses and is emerging as an option in vascular and tumor imaging.
- Thermography uses infrared technology to detect heat patterns and is best for screening for inflammation, vascular issues, and breast health.
Take Control of Your Health
You have the agency and knowledge to advocate for yourself with your healthcare providers. Use it to protect yourself from excessive radiation exposure from unnecessary CT scans. If you must have one, work with one of our providers to shape a recovery protocol that is optimal for you. Our providers can also guide you to alternatives to discuss with your specialist when possible.
Be Informed. Advocate for Yourself. Be Well.
