Our Purpose

Early Detection Changes Lives

Heart disease and cancer are the top two causes of death in America and around the world. These silent killers are taking millions of lives every year because they show no symptoms until it’s too late.

Our mission at Life Guard Imaging is to scan our patients annually through a long-term preventative program.

Our low radiation, high-resolution CT scanner creates 3D images of a patient’s internal organs, aiding in the detection of these deadly diseases before their first symptoms are felt. Early detection saves lives.

For example, breast cancer is the most diagnosed cancer in America, yet it has the highest survival rate. Why? Early detection through annual mammograms.

We’re here to help

We bring true awareness to annual health and wellness initiatives. We take the guesswork out of healthcare by providing three-dimensional images for the internal organs of the torso. The data produced by our scans provide information that can’t be captured through basic blood cultures. It aids in detecting abnormalities that could be developing into potentially harmful health issues.

  • Your first scan is used as a baseline for all future scans. If anything changes, your healthcare professionals can plan a course of action to treat the illness.
