CAMRT Radiography Practice Exam

Which imaging test combines X-ray technology with the use of an endoscope?

1. Fluoroscopy

2. CT scan

3. ERCP

4. Nuclear imaging

The correct answer is: ERCP

The correct answer is indeed the imaging test that combines X-ray technology with the use of an endoscope, which is ERCP (Endoscopic Retrograde Cholangiopancreatography). This procedure is specifically designed to visualize the bile ducts and pancreatic duct. During ERCP, an endoscope is passed through the mouth, esophagus, and stomach into the duodenum, where a contrast dye is injected into the bile and pancreatic ducts. X-ray images are then taken to allow for detailed visualization of these structures, helping to diagnose issues such as blockages, stones, or tumors. In contrast, fluoroscopy, while it involves X-ray technology, does not use an endoscope; it provides real-time imaging of live movements within the body. A CT scan is a more advanced imaging technique that generates cross-sectional images of the body but does not utilize an endoscope in its procedure. Nuclear imaging, on the other hand, utilizes radiopharmaceuticals and is not related to X-ray technology or the use of an endoscope.
