What To Expect During Your First CT Scan: A Step-by-Step Guide

Are you feeling nervous about an upcoming medical imaging appointment? If you are wondering, “What is a CT scan, and how can I prepare for my exam?” you’re not alone.

City Wide Radiology offers an advanced CT scan in Brooklyn, NY, to provide detailed images of your body’s internal structures. In this guide, City Wide Radiology will explain what a CT scan is and what you can expect during your examination.

Understanding CT Scan Technology

A CT scan, or computed tomography, combines specialized X-rays and advanced computer technology to create detailed cross-sectional images of your body. Unlike traditional X-rays that only show flat images, CT scanning provides a comprehensive view of your organs, bones, and soft tissues. 

Millions of CT scans are performed each year, with orders increasing annually as they help doctors:

  • Diagnose injuries and diseases
  • Plan surgical procedures
  • Monitor treatment effectiveness
  • Guide biopsies
  • Detect internal bleeding

How Does a CT Scan Work?

Computed tomography uses a rotating X-ray machine that circles your body while you lie on a table. The machine captures multiple images from different angles, which sophisticated computer software combines to create detailed cross-sectional pictures.

According to the Centers for Disease Control and Prevention, modern CT imaging technology can reveal:

  • Bone and joint problems
  • Internal injuries
  • Cancer
  • Cardiovascular disease
  • Brain abnormalities

Preparing for Your CT Scan in Brooklyn, NY

Now that you know the answer to “What is a CT scan?” it’s time to prepare for your appointment. Your doctor will provide specific instructions before the examination. Following these guidelines carefully helps ensure clear, accurate imaging results. 

You may need to:

  • Fast for several hours before the scan.
  • Avoid certain medications.
  • Wear comfortable, loose-fitting clothes.
  • Remove metal objects like jewelry.
  • Inform staff about any allergies or medical conditions.

If you’re scheduled for an abdominal CT scan, your doctor might ask you to avoid eating for four to six hours beforehand. Patients with diabetes or those taking specific medications should discuss their management plan with their healthcare provider before the scan. 

What To Expect During Your CAT Scan in Brooklyn, NY

The scanning process typically takes 15 to 30 minutes, though your appointment time may be longer. Before your scan begins, you’ll change into a hospital gown to prevent any metal from interfering with the imaging process.

Preparing for the Scan

A certified radiology technologist will escort you to the scanning room. You’ll see a large, donut-shaped machine with a motorized table that slides through the center. The technologist will:

  • Help you lie comfortably on the padded examination table.
  • Position your body correctly for the specific area being scanned.
  • Place a pillow under your head and knees for comfort.
  • Explain the importance of remaining still during imaging.
  • Ensure you understand all communication methods.

During the Scanning Process

The table will slowly move through the CT scanner’s circular opening. You might hear whirring or buzzing sounds as the machine rotates around you to capture images. The technologist will:

  • Communicate with you through an intercom system.
  • Give clear instructions about breathing patterns.
  • Monitor the entire procedure from a nearby room.
  • Check on you regularly to ensure your comfort.
  • Make any necessary adjustments to capture quality images.

Understanding Contrast Material

When researching the answer to “What is a CT scan?” you’ll find that some CT scans require a contrast agent to provide better image clarity. If your doctor has ordered a scan with contrast, the process includes these additional steps:

  • The technologist will check your medical history for allergies.
  • They’ll insert an IV line, typically in your arm.
  • You may feel a warm sensation when they inject the contrast.
  • The technologist will carefully time the imaging with the contrast flow.

Some patients report a metallic taste in their mouths when receiving the contrast material. This is normal, as are temperature fluctuations during the exam. These symptoms will quickly resolve after the exam. 

Specialized Positioning

During the exam, the technician will give you various instructions. Depending on the area being examined, you may need to:

  • Hold your breath briefly during certain scans.
  • Place your arms above your head.
  • Lie on your side or stomach.
  • Remain perfectly still for short periods.
  • Follow specific breathing instructions.

The radiology team understands that staying motionless can be challenging. They’ll work with you to ensure you’re as comfortable as possible while obtaining the necessary diagnostic images. Remember, clear communication with your technologist helps ensure the best possible scan results.

After Your CT Examination

Most patients can resume normal activities immediately after their scan. If you received contrast material, you should:

  • Drink plenty of water.
  • Watch for allergic reactions.
  • Follow any specific instructions from your healthcare provider.

FAQs

What’s the Difference Between CT Scans and Regular X-Rays?

The difference between CT scans and regular X-rays is that the former provide detailed 3D images of internal structures, while the latter only show 2D views. CT scans combine multiple X-ray images taken from different angles to create comprehensive cross-sectional pictures that help doctors examine organs, bones, and tissues with greater precision.

How Long Does a CT Scan Take?

Most CT scan examinations take 15 to 30 minutes, though the actual scanning time may be just a few minutes.

Is Radiation From a CT Scan Dangerous?

CT scans use low-dose radiation that is higher than X-rays but is still considered safe when medically necessary. 

Do I Need a CT Scan or an MRI?

Your healthcare provider will determine whether a CT scan or other imaging method best suits your medical needs. If you’re still wondering, “What is a CT scan, and why do I need one?” consult your doctor or call our team at (718) 236-6800 to learn more.
