PET-CT in inflammatory diseases

PET/CT is currently the most advanced imaging method for inflammatory diseases. It combines the advantages of positron emission tomography (PET) and computed tomography (CT) in a single device. The PET can display the sugar metabolism, which is increased in the centre of inflammation, whereas the CT can localize where exactly the centre of inflammation is. A PET/CT examination may be necessary in cases of fever of unknown origin or vascular inflammation (vasculitis).

Examination procedure

First we will inject you a small amount of a low-radiation marker substance. This substance will accumulate in metabolically active tissue.

The substances used are very well tolerated; allergic reactions are not known. The radiation load is low and quickly degraded.

After the injection of the substance, you relax for about an hour in a relaxation room.

We will then record PET/CT images, which takes about twenty to thirty minutes.

During recording you will lie on a narrow examination table, that slides into and out of the round whole of the PET/CT unit. The opening is quite large and the tunnel is so short that you do not have to feel constricted. The measurement proceeds almost noiselessly.

The examination takes about two hours.

 

Preparation before and after the examination

Please do not eat at least 7 hours before the examination.

Please drink enough water or unsweetened tea before testing.

You can take your medication as usual, however we kindly ask you to bring a list of your medications.

Please, do also bring the results of all preliminary examinations. Particularly important are findings and images (slides, prints or CD) of the last CT and MRI examinations.

The radiotracer is individually ordered for each patient and is not storable (the costs run several hundred euros). Hence we kindly ask you to always keep your appointment on time and if for any reason you need to reschedule or cancel your appointment please do this at least two days in advance.

People with diabetes should contact us by calling 0611-577519.

The examination results will be sent to the attention of your treating physician as soon as possible. He will then contact you to discuss the results as well as the treatment options.

Please do not hesitate to contact us, if you have any further questions!
