Radiology

The radiology team uses a range of imaging technologies to diagnose and treat eye conditions.

Moorfields Eye Hospital NHS Foundation Trust's radiology team provide an in-house service for head and orbit (eye socket) CT scans, a variety of x-rays and dacrocytograms.

They also arrange other imaging such as MRI, DEXA bone scans and lacrimal scintigraphy at the request of your consultant. 

This imaging does not take place at Moorfields, but you will remain in the of our radiology team should you need other imaging.  

 

Visiting the department 

You will be greeted at our reception by our radiology clerical officer who will book you in for your imaging.

Your CT scan, x-ray or dacrocystogram will be performed by a qualified and registered diagnostic radiographer.

 

Making an appointment 

We only accept referrals from Moorfields Eye Hospital clinicians.

We provide an on-the-day service for patients who are referred to us from our A&E department and clinics. 

If you would prefer to have your imaging done on a specific date then an appointment can be arranged for you.

 

CT scan

Your doctor has asked us to perform a computer tomography (CT) scan of your head and/or eyes. A CT scan uses X- rays and a computer to create detailed cross-sectional images of bone, soft tissue and blood vessels.

This section is designed to provide you with more information about this scan and what will happen at your appointment, answering some frequently asked questions patients may have.

If you have any queries, please do not hesitate to contact a member of the radiology team.You can contact us via the main switchboard on 0207 253 3411, extension 2064.

The X-ray and CT department is located on the ground floor of Moorfields Eye Hospital, 162 City Road, London, EC1V 2PD.

 

CT scan frequently asked questions

How long will my appointment be?

Your appointment should last no more than 15 minutes.

 

What will happen at my appointment?

When you arrive at your appointment, we will check your details and ask a few questions about any allergies and previous medical history. We will also ask you to remove any metallic items from near your eyes, such as earrings, hair clips and glasses as these can interfere with the image.

During your scan you will be asked to lie on your back with your head positioned in a headrest. Unlike an MRI scan, where you are placed inside a tunnel, you shouldn't feel claustrophobic.

The radiographer performing the scan may give you an injection of X-ray dye, also known as contrast media. This dye enables certain structures such as blood vessels to be seen more clearly. The injection is given through a small cannula placed in a vein in your arm and may give you a warm sensation which passes quickly.

 

Are there any risks to having a CT scan?

A CT scan involves exposure to radiation in the form of X-rays. The amount of radiation youare exposed to during the CT scan is very small. In excessive amounts, X-ray radiation can increase the risk of cancer.

The doctor who has requested your examination believes that the benefit of the scan outweighs the risks that are involved, but please discuss this if you have any concerns.

 

 

What happens after my scan?

After the scan, some patients need to return to A&E or clinic, where their doctor will be able to review the results. Others go straight home. If you are going home, please check that you have a follow-up appointment booked. The results of your scan will be discussed at this follow-up appointment.

Dacrocystogram (DCG)

Your doctor has asked us to perform a special type of X-ray called a dacrocystogram (DCG). The main purpose of a DCG is to check that your lacrimal system is clear and your tear ducts are working as they should.
