What is this test?
This test uses X-ray imaging (fluoroscopy) to visualize and confirm the correct position of a central venous catheter (CVC). A central venous catheter is a thin, flexible tube inserted into a large vein, typically in the neck, chest, or groin, to deliver medications, nutrients, or to monitor blood flow. The imaging helps healthcare providers ensure the catheter tip is in the right location and that no complications have occurred during placement.
How is the test performed?
During the procedure, you will be positioned either sitting up or lying down, depending on where the catheter was placed. The technologist or radiologist will take X-ray images of the relevant body area (commonly chest/neck for internal jugular or subclavian catheters). For fluoroscopy, a continuous X-ray beam creates real-time images, allowing dynamic assessment of catheter position. The procedure is typically completed within 5-15 minutes and is painless.
Are there any risks?
This test involves minimal radiation exposure. The radiation dose is generally low and considered safe for diagnostic purposes. However, inform your healthcare provider if you are pregnant, as special precautions may be needed. The main purpose of this test is actually to prevent more serious complications by ensuring proper catheter placement.
Reference range
Adult: 3.5-5.0 mmol/LN/A
Informed consent required. Verify allergy history for contrast media if used. Remove clothing and jewelry from chest/neck area. Remove metal objects that may interfere with imaging. Notify technologist of any existing catheters or implants.
