Computed Tomography (CT)

The Revolution EVO is designed to provide the high-resolution, low-dose images and answers that increase your confidence, even when performing advanced procedures.

  • Best-in-class Image quality (0.28mm spatial resolution) – helpful in seeing and diagnosing small lesions.

  • Low Dose Algorithm to reduce patient dose by up to 50% and achieve twice the spatial resolution.

  • Low-Dose CT Lung Screening protocol.

  • Calcium Scoring CT to determine amount of calcium in the coronary arteries.

  • Smart Metal Artifact Reduction – algorithm to remove metal caused from hip/knee implants/spine hardware, surgical clips for easier interpretation when metal is present. Smart Metal Artifact Reduction (MAR) is designed to reveal anatomic details obscured by metal artifacts, helping to utilize CT scans and diagnose disease with greater confidence.

  • Advanced in-room workflow to assist technologist during trauma imaging.

Low Dose CT Lung Cancer Screening

Are you a smoker or a former smoker?

If you are a smoker or a former smoker, a simple screening at Sevier County Medical Center could be a life saver.   Lung cancer is the leading cause of cancer death in the U.S. and 85% of cases occur in cigarette smokers.  Studies show low dose computed tomography (LDCT) lung scans using low doses of radiation can effectively detect lung cancer in its earliest stages and most importantly, lower your risk of dying from lung cancer. 
LDCT works much like an Xray exam to produce images of your chest and lungs.  This scan detects lung abnormalities with 90 percent less radiation than a conventional CT scan.  If you have a high risk of lung cancer but have no signs or symptoms, a LDCT screening could help you catch potentially cancerous spots at their earliest and most treatable stage.

You are considered high risk if you are:

1.    Between the ages of 50 and 77.

2.    Have a smoking history of 20 pack years (1 pack per day x 20 years)

3.    Currently a smoker or have quit in the last 15 years.

Cardiac Calcium Scoring

  • A coronary calcium scan is done to check for calcium in the arteries that supply the heart. It can help diagnose early coronary artery disease.

    Coronary artery disease is a common heart condition. A buildup of calcium, fats and other substances in the heart arteries are often the cause. This buildup is called plaque. Plaque collects slowly over time, long before there are any symptoms of coronary artery disease.

    A coronary calcium scan uses a series of X-rays to take images that can see if there's plaque that contains calcium.

    This test might be done if:

    ·         You have a strong family history of early coronary artery disease.

    ·         Your risk for heart attacks is intermediate, not low, or high.

    ·         Your level of risk of heart attacks is uncertain.

    A coronary calcium scan may help:

    ·         Understand your risk of heart disease.

    ·         Plan treatment if you have a low to moderate risk of heart disease or if your heart disease risk isn't clear.

    A coronary calcium scan is not recommended as a general screening test for those known to be at high risk for heart attacks. It also isn't suggested if you have had a heart attack, a heart stent or coronary bypass surgery — because other tests or procedures that are done for those events show the heart arteries. Ask your health care team if a coronary calcium scan is right for you.
