What KryptoScan is and what it is used

This medicine is for diagnostic use only.
KryptoScan is used through a scan to examine the:
• lung function and
• blood circulation in the lungs.
This medicine contains a radioactive substance, from which another
radioactive substance called 81mKrypton , can be received. 81mKrypton collects
in the lungs when inhaled.
The radioactive substance can be photographed from outside the body,
using special cameras which take a scan. This scan shows the distribution of
radioactivity within the organ and body. This also gives the doctor valuable
information about the structure and function of that organ.

Pregnancy and breast·feeding
• Pregnancy
Tell your doctor if you are pregnant or think you could be. Your
doctor will only administer KryptoScan during pregnancy if it is
absolutely necessary, as it could harm the unborn child .
• Breast·feeding
Tell your doctor if you are breast-feeding as he may delay
treatment until breast-feeding is finished . However, if your doctor
considers KryptoScan to be absolutely necessary, breast-feeding
need not be interrupted.
Ask your doctor or pharmacist for advice before taking any medicine.

How to use KryptoScan

KryptoScan will always be used in a hospital or similar setting. It will only
be administered to you by qualified people trained to safe handle
radioactive material.
Your doctor will decide the KryptoScan amount to be used. The
lowest dose possible will be used to produce adequate X-ray images.
The usual dose is:
Approximately 18 MBq per kg body weight per scan. 4 to 6 scans are
usually sufficient.
MBq is the unit used to measure radioactivity, and defines the
activity of a quantity of radioactive material.

Children under 18 years
Lower doses are used for children.
Method of use
This medicine is inhaled using a face mask or airway. The scans will
be made as soon as you begin inhaling. You will be asked to stop
inhaling between the different scans , so that the camera may be
repositioned . This is necessary to acquire different images .

If you use more KryptoScan than you should
It is unlikely that overdose will occur as this medicine is given under control
by a doctor. However, if this happens you only need to move away from the
source of the inhalation gas to an area free from radioactivity .
