Chest x-ray vs low-dose CT in emergency department
Part of Infections, Lungs & breathing clinical trials.
This trial compares two types of chest imaging for adults in the emergency department who might have community-acquired pneumonia (CAP). It helps find out if a low-dose CT scan is better than a regular chest x-ray for diagnosing this condition.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are an adult coming to the emergency department during daytime weekday hours.
- Your doctor is considering pneumonia (CAP) as a possible diagnosis.
- You can safely complete either a chest x-ray or a CT scan.
- You do not need emergency imaging for a critical condition, such as a collapsed lung (pneumothorax).
- You are not pregnant.
- You do not need extra imaging beyond the chest (like abdominal CT).
- You are not severely overweight beyond the scanner's limit.
- You do not have severe dementia or need sedation for imaging.
- You are not on a breathing machine (mechanical ventilation).
- You do not need medical staff escort during transport.

This study compares three imaging methods — ultrasound, X-ray, and CT scan — to see how well they detect chest injuries in people who have had a blunt chest trauma. The goal is to find the best way to quickly and accurately diagnose injuries so patients get the right care.
This study tests a new portable chest X-ray that can be used in the ICU to check for problems like fluid in the lungs, trouble breathing, or swallowing issues. It is designed to help doctors see these problems more easily without moving you to the radiology department.
This trial is testing whether low-dose CT scans can help find lung cancer early in people at high risk because of their smoking history. If you join, you will get a special type of chest scan that may help catch lung cancer sooner, when it's easier to treat.
This research study tests a special chest CT scan to help diagnose acute pulmonary embolism—a blood clot that suddenly blocks blood flow in your lungs. You may qualify if you're already getting a CT scan for suspected lung clots and meet basic health requirements.
This trial tests a new way to take CT images during a lung biopsy that uses less radiation. It aims to make the procedure safer and clearer for patients.
This study tests a special low-radiation CT scan with a contrast dye called Iomeron 400 to see if it works well for checking lung nodules or pneumonia.
