Summit Remains Open And Has Taken Precautionary Measures To Help Ensure Your Safety


Low Dose CT



At Summit Radiology, we know that early detection is a proven, successful strategy for fighting many forms of cancer. We offer lung screening with low-dose computed tomography (LDCT) for people at high risk for lung cancer.

Low-dose CT for lung cancer screening is the only recommended screening test for the disease. CT scans of the chest provide more detailed pictures than X-rays and are able to detect even very small nodules in the lungs. LDCT of the chest is especially effective for diagnosing lung cancer at its earliest, most reliable stage. LDCT is fast, painless and noninvasive. No contrast material is required, and no radiation remains in the body after a CT exam. The main benefit of screening is early detection which is the most effective way to beat lung cancer.

Your procedure will be performed by an ARRT Registered Technologist and read by one of our Board-Certified Radiologists. Results are sent directly to your physician’s office within 24-hours of your completed appointment.


The US Preventive Services Task Force, American Cancer Society, American Lung Association, and American Medical Association recommends low-dose CT screening as a means to reduce the chance of dying from lung cancer in those at a high risk of developing lung cancer. Individuals considering low-dose CT screening should understand the following points:

  1. Smoking cessation remains the most effective way of reducing the risk of developing lung cancer. The single best way to preventing lung cancer is to never start smoking.
  2. Medicaid and some insurance companies may not cover the cost of low-dose CT screening. However, any follow-up care required after the exam will likely be covered by your insurance or Medicare/Medicaid.
  3. A low-dose CT scan has the potential for revealing abnormalities that are not caused by lung cancer and that you did not expect. These findings may require that you be subjected to additional diagnostic procedures, which have their associated risks and costs.
  4. Low-dose CT scans expose you to less radiation than normal CT scans, but you are still exposed to a low level of radiation.


The American College of Radiology has set specific requirements for those individuals who may be seeking LDCT Lung Screening.

The recommended screening population is listed below:

  1. Patients who are between the ages of 55-80 years old;
  2. Have no signs or symptoms of lung cancer;
  3. Have a 30 pack-years or greater history of tobacco smoking. You can calculate your individual pack years by going to:
  4. Is no longer smoking or one who has quit smoking within the last 15 years;
  5. Have a written order for the LDCT from your physician following a lung cancer screening counseling and shared decision-making visit.

*Written orders for both the initial and subsequent LDCT lung cancer screenings are required.
