RX colon (large intestine)
In an RX examination, we take images of parts of the body based on X-rays. By introducing contrast fluid into the colon, we get a better image.
Plan your appointment
Course of the examination.
An RX colon (imaging of the large intestine) takes about 20 minutes.
- The nurse will escort you from the waiting room to the examination room. He/she will tell you what clothes or jewelry you need to take off for the examination.
- We insert a probe (sonde) through the anus into the rectum. This is how we fill the colon with contrast fluid.
- You take your place on the X-ray table.
- The RX tube passes centrally over the part of the body to be examined by means of a light visor. If necessary, the RX table can be moved.
- It is essential to follow the guidelines carefully when you are asked not to move or hold your breath during imaging. Moving or breathing during the examination usually causes an illegible image.
The radiologist who performed the examination makes an initial interpretation of the images during the examination. After the final interpretation, the radiologist sends a report to the doctor who requested the examination. Only this doctor can discuss the results with you.
This examination is only possible by appointment. Please always bring your identity card, your doctor's prescription and any previous radiological examinations with you.
Preparation
- The day before the examination, take a laxative (Prepacol) as prescribed by the doctor.
- On the day of the examination itself, only a light breakfast is allowed.
Aftercare
To remove the contrast substance as quickly as possible, we recommend that you drink plenty of fluids after the examination.
