Brain PET CT (Positron Emission Tomography – Computed Tomography) is technologically advanced imaging technique of brain diagnosis. This diagnostic procedure is highly effective in detecting various brain conditions and diseases. PET CT brain is helpful in detecting the diseases like epilepsy, Alzheimer’s disease, brain tumors, Parkinson’s syndrome and other type of neurological disorders. PET CT brain is helpful in detecting the impact of stroke or medical treatment used to treat the condition of brain. Brain PET CT is specifically designed to give anatomical and metabolic status of brain, which helps to detect all the conditions related to brain abnormality.
Purpose of Brain PET CT
Brain PET CT is primarily used to assess brain function in various conditions. Its purposes include:
- PET CT brain helps to detect the degradation of neurons in early stages leading to diseases like Alzheimer’s, Parkinson’s syndrome etc.
- PET CT brain is helpful in identifying the seizures and help for surgical planning for brain
- PET CT brain helps to detect the current status of brain and its abnormality.
- This test helps to diagnose the effect of treatment given to brain
- PET CT helps to detect the condition of recurrence in brain tumors
- PET CT is also helpful in research purpose, which helps to determine the activity of neurotransmitters and progression of diseases.
Procedure of Brain PET CT
There is a structured procedure for the test diagnosis of Brain PET CT and these include:
- Preparation
- Patients are asked to fast for 4–6 hours before the scan.
- Diabetic patients are advised to keep blood sugar under control, as high glucose levels can affect results.
- Medications are reviewed by the doctor before the scan.
- Tracer Injection
- An infection containing radioactive tracer is used for the detection of brain abnormalities.
- Radioactive tracer has the property of highlighting active areas of brain.
- Waiting Period
- Patient is suggested to wait around 40-60 minutes before going for scan.
- Movement and talking are minimized to avoid altering brain activity.
- Scanning Process
- The patient lies on a flat table that slides into the PET CT scanner.
- The scanner captures detailed images of brain activity and structure.
- The whole procedure of Brain PET CT will take around 40-70 minutes on average.
- Completion
- After the scan, patients can resume normal activities.
- The radioactive tracer naturally leaves the body through urine within a day.
Benefits of Brain PET CT
Brain PET CT provides several advantages over conventional imaging:
- Early diagnoses of neurological diseases before structural changes are visible.
- High accuracy in identifying Alzheimer’s and other dementias.
- Helps locate epileptic seizure focus more precisely than MRI alone.
- PET CT brain is helpful in guiding neurological abnormalities
- PET CT brain is helpful in cancer types.
- Helps to evaluate brain activity and other psychological conditions.
- PET CT brain is generally safe except certain amount of radiation exposure.
Limitations of Brain PET CT
There are various limitations of Brain PET CT apart from being various beneficial for the patient.
- The cost of PET CT Brain is high comparing routine checks like CT, MRI and other pathological tests.
- There is limited availability of this facility in rural areas
- There is slight risk or radiation exposure and frequent tests have health risks
- There may be sometimes false positive which can lead to treatment.
- Cannot replace MRI or CT entirely, usually used in combination for best results.
Cost of Brain PET CT in Delhi
Brain PET CT cost in Delhi slightly vary depending on various factors like technology used, contrast material, location etc. The cost of Brain PET CT ranges from Rs. 12,000 and goes up to Rs. 30,000.

Conclusion
Brain PET CT is advanced and provides unique features to access the remote and untouched locations of brain. This helps in detecting detailed structural anatomy, metabolic abnormalities and neural degradation of brain. PET CT brain is helpful in detecting the diseases like epilepsy, Alzheimer’s disease, brain tumors, Parkinson’s syndrome and other type of neurological disorders. PET CT brain is helpful in detecting the impact of stroke or medical treatment used to treat the condition of brain. Brain PET CT is specifically designed to give anatomical and metabolic status of brain, which helps to detect all the conditions related to brain abnormality.
Frequently Asked Questions (FAQ’s)
Is Brain PET CT safe?
Yes, but there is slight exposure of radiations and radioactive tracer which can cause allergies.
How long does the Brain PET CT scan take?
The entire process takes about 2–3 hours, including preparation and scanning.
Do I need to fast before Brain PET CT?
Yes, fasting for 4–6 hours is usually required.
Can Brain PET CT detect Alzheimer’s disease early?
Yes, it is highly effective in detecting early metabolic changes linked to Alzheimer’s.
Is Brain PET CT better than MRI?
PET CT shows brain function, while MRI shows structure. Both are often used together for accurate diagnosis.
Is Brain PET CT covered by insurance?
Some insurance plans may cover it if medically prescribed.
Who should avoid Brain PET CT?
Brain PET CT should be avoided by pregnant women or breast feeding women.
