CAT Scan
What is a CT scan?
A CT (Computed Tomography) scan uses X-ray technology and computer imaging to create detailed cross-sectional images of the body. These images provide a comprehensive view of bones, blood vessels, and soft tissues.
- CT Angiography focuses on blood vessels and can detect blockages in the heart, lungs, kidneys, arms, and legs.
How Does It Work?
- Preparation:
- Fasting: Depending on the type of scan, you may need to fast for 4-6 hours before the procedure.
- Contrast Dye: You might be given a contrast to enhance image clarity. This can be administered orally, intravenously, or rectally.
- Medical Records: Bring any relevant medical documents or instructions from your doctor.
- Blood test results for Creatinine and BUN will be required within 30 days prior to the exam for patients aged 60 and over, as well as patients with chronic kidney disease, diabetes, & hypertension. Please ask your physician to order the blood tests and fax prior to the appointment or bring the results with you on the day of your appointment.
- Pregnancy test is required for patients that are of child bearing age.
- Inform Your Doctor: Let your doctor know if you have allergies to iodine contrast material, kidney problems, or are pregnant.
- Preparation:
During the scan
- Positioning: You’ll lie on a motorized table that slides into the CT scanner, a large, doughnut-shaped machine.
- Imaging: The scanner rotates around you, taking multiple X-ray images from different angles. These images are then processed by a computer to create cross-sectional “slices” of the area being examined.
- Contrast Dye: If used, the dye helps highlight specific areas, making them more visible on the scan.
Procedure
- Remove Metal Items: You’ll need to remove any metal objects, such as jewelry, as they can interfere with the imaging.
- Stay Still: It’s important to remain still during the scan to ensure clear images. You may be asked to hold your breath for short periods.
- Duration: The scan itself usually takes 15 – 45 minutes, but the entire process, including preparation, can take up to a couple of hours.
What to Expect?
- Comfort: The procedure is generally painless, though lying still might be uncomfortable for some.
- Noise: The machine may make whirring or clicking sounds during the scan.
- Results: The images help doctors diagnose conditions, plan treatments, and guide procedures.
After the Scan:
- Hydration: Drink plenty of water to help flush the tracer from your body.
- Normal Activities: You can usually resume normal activities immediately after the scan.
If you have any specific concerns or questions about the procedure, it’s always best to discuss them with your healthcare provider. They can provide personalized advice and information based on your medical history and condition.
