General Radiography (x-rays)
CT Lung Cancer Screening
This study provides detailed images of the lungs using Computed Tomography (CT) imaging for lung cancer screening.
Common Uses for the Procedure
This examination is intended for patients at increased risk for lung cancer. This includes patients over 50 years of age that have smoked for more than ten years.
Preparation for the Exam
No preparation is necessary.
The Procedure
You will lie on your back and hold your breath for about 20 seconds while the CT scanner images your lungs. Breathing during the imaging will result in blurry pictures and reduce the quality of the examination. We do not use any needles or contrast agents. The entire examination takes 5 minutes—start to finish.
Symptoms after the Procedure
None.
Benefits
The detailed images of the lungs obtained with CT Lung Cancer Screening are far superior to a standard chest x-ray. This technique can detect early lung cancers that do not produce symptoms and may not be detected by a standard chest x-ray.
Risks and Limitations
Identification of a suspicious lung nodule or mass will lead to biopsy by percutaneous needle technique, bronchoscopy, or surgery. Some lung abnormalities that are most likely benign, rather than cancerous, will require repeated medical imaging follow-up to prove that they are stable over time (not enlarging or growing). Not all lung nodules less than 5mm (.2 inches) will be detected by this technique.
There is exposure to x-ray radiation during this study, and this exam should therefore not be performed if you are pregnant. If you have any other questions about risk, please ask the radiologist.
Making an Appointment
Cardiac CT imaging is currently available at The Imaging Center (Harmony Campus) in Fort Collins, Colorado, and The Imaging Center (Centerra Campus) in Loveland, Colorado. Additional information can be obtained by calling 970-282-2900 or 970-282-2912; a receptionist will direct you to someone who can answer your questions.
