Lung cancer screen (CT scan) -Memphis only
07/23/2009 -
Why: The vast majority of patients diagnosed with lung cancer are destined to die of their disease. However a study of CT screening for lung cancer involving 31,000 smokers in 17 countries has suggested that detection of lung cancer at an early stage has a major impact on survival. CT screening for lung cancer is recommended for men and women age 50 and above with a history of smoking the equivalent of at least a pack per day for 10 years.
What: A CT scanner captures 300 images of the lung during a single breath, and a radiogist reviews the images for suspicious nodules. Since most nodules are benign, the scan is usually repeated in three months and compared to the baseline CT before a decision is made to perform a biopsy or additional tests.

Virtual colonoscopy (CT scan) - Memphis only
07/23/2009 -
Why: All men and women age 50 and above should undergo colonoscopy to detect polyps before they become malignant and cause colon cancer. The standard procedure for colon screening, optical colonoscopy, requires a one-day absence from work and involves considerable inconvenience and the use of anesthesia.
What: Colonoscopy can now be performed non-invasively using a CT scanner and powerful software that allows a radiologist to take a “virtual” tour of the colon. As part of its commitment to state-of-the-art cancer screening, Lifesigns now offers virtual colonoscopy in its Memphis facility and plans to make the test available at all centers in the near future.
