A Linogram is a test to check your child’s Central Venous Catheter/ Line (CVC- a central line used to deliver medicine or nutrition when treatment is needed for more than a week). This information sheet explains what is involved and what to expect. An Easy Read information sheet is included for your child.
When you receive your appointment letter
If you are unable to keep this appointment, please inform the department as soon as possible.
If your child is likely to need a hoist during the appointment, please telephone us so that we can make sure this is ready for you.
Before the appointment
If you are pregnant or think you could be pregnant, please let us know. The x-rays used in the fluoroscopy scan could harm your unborn baby, so we would advise bringing another adult to come into the scanning room with your child.
If your child is 12 years old or older and of childbearing potential, we will ask them about their periods and any possibility that they could be pregnant; this is a legal obligation that we must ask.
The person bringing your child to the scan should have ‘Parental Responsibility’ for them. Parental Responsibility refers to the individual who has legal rights, responsibilities, duties, power and authority to make decisions for a child. If the person bringing your child does not have Parental Responsibility, we may have to cancel the scan.
What to bring with you?
It can help if your child has a favourite toy to hold to comfort them during the study. Electronic devices such as iPads are welcome.
You might want to bring some spare clothes in case any of the contrast liquid spills.
The day of the study
Please dress your child in clothing which does not contain metal, for example zips and buttons.
Arrive at the Radiology department at the time stated in your child’s appointment letter.
You are welcome to stay with your child throughout the test. Everyone staying inside the examination room will need to wear a lead apron.
Before we begin, your child will need to remove any metallic objects and expose their line.
Your child will lay on the x-ray bed and some liquid will be inserted through the line. This liquid shows on X-rays. A series of pictures will be taken with your child lying in different positions on the bed.
After the scan
Once the test is complete you will be free to go.
A report outlining the results of the procedure will be sent to the doctor who referred your child for this test. You or your child will receive the results from your referring doctor.
Are there any risks?
The liquid will not interfere with any medicines your child is taking.
It is our legal duty to tell you about the potential risk of having a fluoroscopy study. The studies are only ever requested if the benefits outweigh the risks involved. The study does use radiation, but the dose is kept as low as possible. This is because the radiographers are specially trained to obtain the best quality pictures while using the lowest amount of radiation possible.
Anyone staying in the room with your child will need to wear a lead apron – this works as a barrier to radiation. We advise that anyone who is pregnant or thinks they might be pregnant should not go into the room.
Are there any alternatives?
Other types of imaging studies, such as a Chest X-ray can be used to visualise the position of the line. However, such tests do not provide enough information to safely assess the line, including any holes or blockages.
