CT Guided Paracentesis
What is a Paracentesis?
A CT scan paracentesis is an exam to drain off fluid in the abdomen.
Procedure
You will be lying on your back for this exam. The CT scan technologist will scan your abdomen to locate the fluid. The Radiologist (x-ray doctor) will insert a needle/catheter into the abdomen, and fluid will be drained off. The needle will be removed after the procedure is completed. Your abdomen will be rescanned after the fluid has been removed. You may be asked to stay for a few hours for observation, if the Radiologist requests it.
Procedure time: 60 - 90 minutes
