What is PET CT Brain with Contrast?
PET stands for positron emission tomography. CT stands for computed tomography. A PET/CT brain scan takes pictures of your brain as it works. It is often done to check for tumors that may be causing memory problems or seizures.
Positron emission tomography (PET) uses small amounts of radioactive materials called radiotracers, a special camera and a computer to help evaluate your organ and tissue functions. By identifying body changes at the cellular level, PET may detect the early onset of disease before it is evident on other imaging tests.
Tell your doctor if there’s a possibility you are pregnant or if you are breastfeeding. Your doctor will instruct you based on the type of exam to be performed. Discuss any recent illnesses, medical conditions, medications you’re taking and allergies – especially to contrast material. You will likely be told not to eat anything and to drink only water several hours before your scan. Leave jewelry at home and wear loose, comfortable clothing. You may be asked to wear a gown.
Preparation for PET CT Brain with Contrast
- Inform your doctor and technician if you are pregnant or may be pregnant before the test.
- You will have to remove your jewellery and avoid wearing clothes with metal objects like metal zips, studs etc. which might interfere with the image
- Get the blood urea and creatinine test done to evaluate kidney function and to ensure safety of contrast before taking up the procedure.
