Fluoroscopy imaging service



We have fluoroscopy imaging facilities at Guy's Hospital and St Thomas' Hospital. Please remember to check your appointment letter before you come for your scan.

What is a fluoroscopy procedure?

A fluoroscopy procedure is a widely used test which creates a live image of the inside of the body, much like a video. It helps us find the cause of your problem and to decide the best treatment option for you.

Depending on the type of examination you are having, you may need to prepare beforehand for your fluoroscopy procedure. Your letter will give you all of the information you need which is specific to the test you are having. Please make sure you read the information in your letter carefully before you come to hospital.

  • Are there any risks?

    Fluoroscopy procedures use x-rays. X-rays are a type of radiation known as ionising radiation. The dose of radiation used is very low. The radiographer will ensure the dose is kept as low as possible and that the benefits of having the x-ray outweigh any risks.

    Sometimes we need to give you an injection of contrast dye during the scan, to help us see your internal organs better. This contains iodine, which some people are allergic to. Before your scan we will check whether you have had any previous allergies.

  • Giving your consent

    The radiographer will ask you if you are happy for the examination to go ahead. This is called verbal consent and may only involve the radiographer checking you are booked for the correct examination. If you do not wish to have the examination or are undecided, please tell the radiographer.

    It is your decision and you can change your mind at any time. Please bear in mind that not having the examination may delay your diagnosis as the doctors may not have all of the information that they need. You can ask the radiographer any questions you have at any time before, during or after your examination.

    If you would like to read our consent policy, please ask a member of staff.

  • What happens during the fluoroscopy procedure?

    There are different types of fluoroscopy procedures. Depending on your procedure, you may be asked to remove jewellery and/or certain items of clothing. The radiographer may ask you to move into different positions, either lying on the x-ray table or whilst you are standing up, depending on the type of scan requested.

    You should not feel any pain during the scan. The most difficult part is keeping still. If you find it difficult or uncomfortable lying still, please tell the radiographer.

    The time taken for the procedure usually takes between 10-30 minutes, depending on the area of your body that is being examined. If any preparation is needed, you may need to come to hospital one hour before your scan.

  • What happens after the fluoroscopy procedure?

    In most cases, you will be allowed to go straight home, or back to the ward if you are an inpatient.   

    The images will be studied by a radiologist (doctor who uses x-rays to diagnose and treat illnesses) and the results will be sent to the doctor who referred you.

    You may already have an appointment with the doctor who referred you. If not, please arrange one to discuss the results and any treatment you may need.

    If you are an inpatient, the results will be given to the doctors looking after you on the ward.
