CT Scans

Fast & Cost-Effective Imaging

A computerized tomography (CT) scan is an X-ray that captures images of the body from different angles. Like most imaging tests, CT scans are painless and noninvasive. They can also be done very quickly.

CT scans are often used in the following situations:

  • Trauma evaluation
  • Assessing damage from a severe headache or stroke
  • Diagnosing the cause of severe stomach pains
  • Diagnosing Pulmonary embolism
  • Diagnosing and tracking the spread of cancer
  • Finding complex bone fractures
  • Diagnosing sinus disorders
  • Diagnosing lung diseases

How Does it Work?

A CT machine looks like a large square doughnut. You will lie down on a table that will slide up and down in the scanner. Unlike an MRI, only the part of your body that is being examined needs to be in the scanner. You will still be in open space, so this test is generally not uncomfortable for people who are claustrophobic (uncomfortable in small spaces). This test does involve some radiation exposure, but only a very small amount.

The test only takes about 30 minutes. No injections, incisions, or anesthesia are necessary, so you should be fine to drive yourself home afterward.

We also offer Lo-Dose CT Screening.


CT scans are sometimes done in combination with positron emission tomography (PET) scans. This test is known as a PET/CT scan. For this test, you will be injected with a small dose of a sugar solution that contains very small amounts of radioactive material. This solution is then absorbed into an organ, and the radioactive material makes it easier for the PET/CT scanner to see the insides by highlighting the area it was absorbed into.

PET/CT scans are commonly used to:

  • Track the spread of cancer
  • Assess brain disorders, such as epilepsy or Alzheimer’s
  • Assess disorders of the central nervous system, such as Parkinson’s
  • Assess cardiovascular health
