A CT (Computed Tomography) scan is a non-invasive imaging technique that uses X-rays and advanced computer technology to create detailed cross-sectional images of the chest, lungs, heart, and blood vessels. It provides a much clearer and more detailed view than standard X-rays, helping doctors diagnose a wide range of conditions.
Your doctor may order a CT scan to:
1.) Evaluate chest pain, shortness of breath, or unexplained cough
2.) Detect or monitor lung conditions like infections, pneumonia, COPD, or lung nodules
3.) Screen for lung cancer in high-risk individuals
4.) Diagnose coronary artery disease, pericarditis, or heart valve issues
5.) Assess blood vessel abnormalities such as aneurysms or pulmonary embolisms
The scan itself takes about 10 to 15 minutes, though you may need to allow 30 to 45 minutes total for check-in, preparation, and post-scan instructions.
Contrast dye may be used to enhance imaging, particularly for CT angiography (CTA) to assess blood vessels or cardiac CT scans for coronary artery disease. If contrast is required, it may be administered orally or through an IV injection. Your doctor will determine whether contrast is necessary based on the reason for your scan.
No, a CT scan is a painless, non-invasive study. You’ll lie comfortably on a table while the scanner takes images.
Some insurance plans require a doctor’s referral, while others do not. It is important to check with your doctor and your insurance benefits manager to determine if one is needed before scheduling.
Yes, CT scans use a low dose of radiation, and they are considered very safe for diagnostic imaging. If you’re pregnant or have concerns about radiation exposure, consult with your doctor before scheduling.
You may be asked to avoid eating or drinking for a certain period of time before your scan, especially if contrast is recommended. Wear comfortable clothing and remove any metal objects like jewelry. Our team will review your medical history when you arrive for your appointment to ensure the proper preparation was followed before the study begins.
