During the examination

Do you lie in a tunnel like during an MRI scan?

• No. The scintigraphy machine looks different – it has two movable arms that slowly rotate around you. It is not a narrow, noisy tunnel like an MRI scanner. The room is spacious and airy, and most people feel completely at ease.

Can a loved one accompany me?

• Certainly. Your companion can bring you, wait in the waiting room and take you home afterwards. However, they are not allowed into the examination room, as radioactive substances are used there and only staff and patients are permitted to enter.

What if I have claustrophobia?

• There is no need to worry. The equipment is designed to make the space feel open. If you know that you are afraid of enclosed spaces, tell the nurse in advance – the staff are experienced in dealing with this fear and will help you get through the examination.

Are allergic reactions possible?

• Allergies to radiopharmaceuticals are extremely rare. Only trace amounts of the substance are administered, and it is quickly broken down. Most patients tolerate the examination without any problems.

What if I have diabetes?

For most scintigraphies, this is not a problem. It is only important to inform the staff what treatment you are taking and when you last ate. They will then let you know if any minor adjustments to the preparation are necessary.

Is the examination okay if I have a pacemaker?

• No, it is not a problem. Unlike magnetic resonance imaging, scintigraphy is safe even for patients with pacemakers and other implants.

Could other problems be found besides the one I am being examined for?

• Yes, sometimes changes unrelated to the original problems are found during the examination. In such cases, the doctor will notify you and recommend further steps.

Why do I have to wait after the substance is administered?

• Because the radiopharmaceutical needs time to reach the organ being examined. Only then will the image be clear and understandable.

Can I fall asleep during the examination?

• Yes, and many patients take advantage of this – the examination is calm and quiet. Just do not move.

How is the radioactive substance administered into the body?

• Most often by injection into a vein – similar to a blood test. In some cases, you may drink or inhale it, depending on what is being examined. Each substance is modified to be completely safe for the body.

Will I feel anything when the substance is administered?

• Most people only feel a slight prick when the needle is inserted. You will not feel the substance itself – it has no taste, smell or warmth. You will feel completely normal after the administration.

What does the device used look like?

• The device is called a gamma camera and has the shape of a large circular head or two arms that move around the body. The entire examination takes place in a quiet room. The camera emits only a quiet motor sound, and the staff will communicate with you during the examination.

Do I have to lie completely still during the examination?

• Yes, it is important to remain as still as possible during the scan so that the image is not blurred. If you move, the device may repeat part of the scan. However, each scan usually only takes a few minutes and you can rest briefly between them.

What if I have back pain and cannot lie still for long?

• Please inform the nurse in advance. The staff can help you with pads, positioning or short breaks. The examination is always adapted to your abilities and comfort.

What if I need to use the toilet during the examination?

• Of course you can. If you have a longer waiting time after the substance is administered, it is advisable to go before the actual imaging. After the radiopharmaceutical is administered, it is advisable to go to the toilet more often, as this helps your body eliminate the substance more quickly.

What does the administered substance taste or smell like?

• Radiopharmaceuticals have no taste or smell. Some types are administered intravenously, others are drunk, but even in such cases they are tasteless.

Do I need to bring pyjamas or a change of clothes?

• No, the examination is performed in normal clothing. We will only ask you to remove any metal objects (belt, jewellery, watch), as they may interfere with the image. We recommend comfortable clothing without zips or metal accessories.

Why do I have to drink a lot of fluids?

• Because the radiopharmaceutical is excreted in the urine. Drinking more water or tea helps your body break down the substance more quickly. It is a simple and effective way to minimise the amount of time the substance remains in your body.

Can I listen to music during the examination?

• Yes, at some facilities. If it helps you relax, you can ask the staff if you can play music or bring headphones.

Can I talk or move during the examination?

• The short answer is: preferably not. Any movement can impair the quality of the image, so it is important to remain still. If you need to communicate anything, just tell the nurse – the examination can always be interrupted and resumed.
