Friendly, comfortable CT scan services

EVDI offers complete CT (computed tomography) scan services. CT scan is a noninvasive medical exam that helps physicians diagnose and treat medical conditions. It utilizes cross-sectional images of the inside of the body to produce multiple images of the area being studied. These images can be examined on a computer, printed or transferred to CD. CT scans of internal organs, bones, soft tissue and blood vessels provide greater clarity and more detail than regular X-ray exams. Read on for more information about specialty CT scans.

CT Angiography

CT angiography is the process of injecting contrast dye to visualize blood vessels throughout the body under CT.


Enterography is a CT of the small intestine with the use of a contrast material to produce a number of detailed images. This exam can be used to help identify and locate inflammation, bleeding sources and vascular abnormalities, tumors, abscesses, fistulas and bowel obstructions.

CT Coronary Calcium Scoring

Are you at risk of a heart attack or stroke?

Early detection with a CT Coronary Calcium Score could save your life!

What is a CT Coronary Calcium Score?

It’s a quick and easy, painless, noninvasive, non-contrast procedure performed on a computed tomography (CT) unit. During this test a technologist can accurately determine the degree of severity of calcification or hard plaque within the coronary arteries, which is an early sign of coronary disease.

Why is Coronary Calcium Scoring important?

Coronary Heart Disease (CAD) is the leading cause of death for both men and women. Often there are no warning signs prior to a cardiac event. Coronary Calcium Scoring can detect life-threatening build-up and gives people the opportunity to change their lifestyles and obtain medication BEFORE extensive, irreversible damage occurs.

What does the Coronary Calcium Score mean?

The lower your score the better. People with CAC scores of zero have a very low risk of heart attack over the next 5 to 10 years; however, patients with scores greater than 100 may be at higher risk and may benefit from targeted prevention with medication.

Who should have a Coronary Calcium Score?

  • Men over the age of 45 and women over the age of 50; however, if a patient has a family history of heart disease, you may want to be tested earlier.
  • No prior stents or coronary artery bypass surgery
  • Not pregnant
  • No calcium score in the last three years

Is a CT Coronary Calcium Scoring exam covered by insurance and is a doctor’s referral needed?

Currently this is a cash pay procedure of $89 (preferably check or charge) which is due at the time of service. Patients will need a doctor’s referral to schedule an appointment for the exam at our Chandler location.

How is the CT Coronary Calcium Scoring exam performed?

The scan takes place while the patient is asked to hold their breath for a period of 10-15 seconds while images are recorded, while a sliding table moves you slowly through the circular CT scanner. The exam is usually completed within 10 minutes.

What are the benefits vs. risks?


  • The exam is painless, fast and easy.
  • A convenient way of evaluating whether you may be at increased risk of a heart attack, which for many, the benefit of an accurate diagnosis far outweighs the risk.


  • Coronary Calcium Scans use a type of X-ray technology therefore you are exposed to a small amount of radiation. The amount is generally considered safe and is similar to what would be used for a mammogram.
  • Women should always inform their physician or CT technologist if there is any possibility that they are pregnant.

How does one prepare for a CT Coronary Calcium Soring exam?

  • Wear loose fitting clothing with no zippers or snaps.
  • You may need to remove some of your clothes (ie: underwire bra, shirt)
  • You will be given a gown to wear during the test.
  • Remove any metal/jewelry that might be in the way of the imaging area.





Low-Dose CT Lung Cancer Screening

Are you at risk of lung cancer?

The American Lung Association states that lung cancer is the number one cancer killer of both men and women.  This makes early detection key and lung cancer screening so important for those at risk, particularly for those who have smoked heavily and for a long time. Talk to your doctor about a low-dose CT lung cancer screening, it could save your life!

Why get screened?

At this time, studies have shown that a low-dose CT scan is the only lung cancer screening tool that reduces the risk of dying from lung cancer. According to the Amercian Lung Association the key is to catch the disease before you have any symptoms and before it spreads.

What is a low-dose CT?

A low-dose CT scan (LDCT) is a non-invasive, non-contrast procedure performed on a computed tomography (CT) unit. It is a special kind of X-ray that takes multiple pictures as you lie on a table that slides in and out of the imaging machine. The images are then combined into a detailed picture of your lungs.

The lung cancer screening scan is not recommended for everyone.  Patient’s will need a doctor’s referral and must schedule an appointment for the exam.

Is lung cancer screening covered by insurance?

Be sure to check with your insurance plan to see what is covered for lung cancer screening and if it will be applied to your deductible. For patients without insurance or who do not wish to file a claim through their insurance plan, cash prices are available.

Where can I find out more about lung cancer and lung cancer screening?
