Questions
How is an abdominal CT scan performed? Since I’ve already had a CT scan of my lungs, can I go to the same hospital and request a 3D reconstruction?
Answers
Analysis of Condition: Before an abdominal CT scan, fasting for 4-8 hours is necessary. Some medical imaging procedures require adequate eating and drinking before they can be conducted. For example, in an abdominal CT scan, the amount of water intake and timing are quite specific. For an upper abdominal CT scan, 300 milliliters of diluted contrast agent needs to be consumed, and the scan can be performed immediately after drinking. When performing a CT scan on the kidneys, the cumulative amount of water intake should reach 800 milliliters, and a 20-minute wait is required before the scan. For prostate, bladder, and gynecological ultrasound examinations, increased water intake is also necessary, and the bladder should be filled before the examination. Guidance: At the hospital for the examination, if needed, the doctor will arrange for you to drink water.
