Pulmonary Diagnostic Testing

Endobronchial Ultrasound (EBUS) and Electromagnetic Navigation

Endobronchial Ultrasound (EBUS)
and Electromagnetic Navigation

We are the only hospital in the St. Louis region to use both endobronchial ultrasound (EBUS) and electromagnetic navigation to better diagnose damaged or diseased tissue found in hard-to-reach parts of the chest. 

Prior to these medical advancements, surgery was required to biopsy lesions or tumors found in areas such as the lungs, heart, esophagus and lymph nodes. Surgical procedures typically require hospitalization, general anesthetics and a longer recovery period. 

EBUS is especially helpful in biopsying tumors, and electromagnetic navigation allows doctors to remove samples of lung tissue that were previously too small to collect. EBUS and electromagnetic navigation are outpatient procedures during which damaged tissue is collected for biopsy from what the physicians see on CT or PET scans. 

Low-Dose CT Scanning

Christian Hospital is the only health care provider in north 
St. Louis County -- and one of the only hospitals in the St. Louis region -- to provide low-dose CT diagnostic technology.

Christian Hospital offers low-dose CT imaging technology to help provide an earlier diagnosis of lung cancer. Studies show a 20 percent reduction in lung cancer deaths when low-dose, non-contrasted CT imaging is used. The improvement is essentially due to earlier stage diagnosis and healing action for earlier stage cancer. 

The National Comprehensive Cancer Network recommends low-dose CT scanning for people who fall into two high-risk categories for developing lung cancer. 

  1. People 55 and older who have smoked a pack per day for 30 or more years, and who have not quit for 15 years
  2. People 50 and older who have smoked a pack per day for 20 years or more, and who have at least one additional risk factor (besides second-hand smoke), such as: 
  • Exposure to radon, asbestos, diesel fumes or heavy metals (welders)
  • Having had certain other cancers or fibrosis of the lung
  • Primary family members who’ve had lung cancer

These high-risk patients have a better chance of surviving the disease when utilizing the low-dose CT screening technique. Screenings are recommended to continue until the patient is 75 or until the patient is smoke-free for 15 years. 

The National Cancer Institute sponsored the National Lung Screening Trial. Results of the trial were published by the National Comprehensive Cancer Network, and reveal a 20 percent reduction in lung cancer deaths when low-dose, non-contrasted CT imaging is used.
