Computed Tomography (CT) Scan: What It Is, What It’s Used For, and the Benefits

Dec 01, 2020

Medicine has evolved ever since its inception. We cannot even begin to imagine a time where people lived without the diagnostic tools we have in our era. Nearly a century ago, X-rays took the medical field by storm. All of a sudden, we could peer into man to see what’s going on. We had now made major leaps and bounds in medical imaging, which had helped save countless lives and stopped certain conditions before they took root.

Computed tomography (CT) scan is one of these medical imaging miracles that we have at Lake Jackson imaging center that our doctors use to diagnose different diseases. However, CT scans are not understood by most people who come to seek urgent care in Lake Jackson. Therefore, let’s take a closer look into what a CT scan is about.

What Is a CT Scan?

In a nutshell, the CT scan used in our 24-hour emergency clinic is an imaging machine that combines rotating X-ray machines and computers to take cross-sectional images of your body.

The images taken by CT scans are more detailed than those taken by conventional X-ray machines. The machine can rotate, take images from different angles, and create slices or cross-sectional images of bones, soft-tissues, and blood vessels.

It is a versatile machine for taking images; however, it is best suited to examine the internal injuries caused by accidents and other types of trauma. A CT scan can be used to take images of any body part. It is a short and painless procedure.

How Does It Work?

A CT scan uses X-rays to capture the image of the specific body part. It emits a narrow X-ray beam that goes around the body part to produce a series of images from different angles. The images are 2D slices. Picture a loaf of bread which you slice. So, the images taken are slices of that body part.

The computer then takes these images and stacks them on top of each other to create a detailed view of the blood vessels, organs, or bones.

What Can CT Scans Detect?

A CT scan can take multiple detailed 3D images of your organs, blood vessels, and bones. Therefore, when you come to our emergency room near you for diagnosis, the CT scan can detect any of the following conditions:

  • Liver masses
  • Cancer
  • Lung nodules
  • Emphysema
  • Bone, joint, and muscle problems such as tumors and bone fractures
  • Excess fluids
  • Internal bleeding
  • Heart disease

Why It’s Done

Other than detecting the issues above, they can be used to:

  • Guide procedures such as radiation therapy, biopsies, and other surgeries
  • Check whether the treatments given to a patient are working, such as cancer treatment
  • Locate the exact position of a blood clot, infection, and a tumor
  • Detect diseases and conditions such as heart disease and cancer

Benefits of CT Scans

CT scans are packed with lots of benefits as compared to conventional X-rays. Some of the benefits of a CT scan that you can expect when you come to our Lake Jackson emergency room include:

  • Taking images of the blood vessels, bone, and soft tissue concurrently
  • It is not as sensitive as MRI to patient movement
  • CT scan produces more detailed images of different types of tissues, including the bones, lungs, and blood vessels
  • Unlike an MRI, images can be taken even if you have an implanted device
  • The examinations are simple and fast, therefore, appropriate during an emergency
  • It is painless, accurate, and non-invasive
  • It is cost-effective
  • It provides real-time imaging, thus making it an ideal tool for minimally invasive procedures
  • Diagnosis based on CT scans can eliminate the need for surgical biopsy and exploratory surgery
