Aga Khan University Hospital Nairobi is home to one of the most sophisticated radiology facilities in East and Central Africa. Our Radiology Department provides a comprehensive range of imaging services, including both routine and specialised procedures.
In our commitment to the provision of world-class healthcare services, the Hospital has acquired an ultra-modern Positron Emission Tomography (PET) CT scanner and Cyclotron, a first in the region.
What is a PET-CT Scan
A PET scan is an imaging test that uses a tiny dose of a radioactive chemical, called a radiotracer, to help doctors see how the organs and tissues are functioning. PET scans are used most often to detect cancer
cells in the body.
PET scans usually identify diseases before they show up on other imaging tests. These diseases include cancer, heart problems and brain disorders. The radiotracer is produced by the Cyclotron unit. A low-dose CT scan is conducted at the same time to get complimentary information about the structure of the various organs and tissues.
About the procedure
A radiotracer is injected in a vein and usually takes upto one hour to be absorbed into the organs or tissues that are being examined. The PET scan itself may take another 30 to 60 minutes. Heart and brain studies take less time for imaging.
PET/CT service is offered as an outpatient procedure unless the patient is already admitted to the hospital. Please plan for at least two hours for the procedure. The doctor will give you detailed instructions on how to prepare for your scan.
After the procedure, you can continue with your normal day routine, unless your doctor tells you otherwise. Drink plenty of fluids to help remove the tracer from your body. Specially trained radiologists will review and interpret the scan images and report the findings to your doctor.
