PET Scans and Brain Imaging: What Patients Should Know

Published on September 29, 2025

When it comes to diagnosing neurological conditions, precision and clarity are essential. PET (Positron Emission Tomography) scans combined with brain imaging techniques give doctors detailed insights into brain activity, metabolism, and structure. For patients seeking the Best PET Scan in Kolkata, understanding how these scans work and what to expect can make the experience much more reassuring.

Why PET Scans and Brain Imaging Matter

Brain disorders such as epilepsy, dementia, tumors, or stroke often require detailed imaging for accurate diagnosis. A PET scan measures how the brain uses glucose (energy), revealing abnormalities in activity that traditional scans might miss. When supported with technologies like MRI or the Advanced CT Scan in Kolkata, patients get a complete and accurate picture of their neurological health.

What Patients Should Expect During a PET Scan

Before the test, patients are given a small amount of radioactive tracer, usually injected through an IV. This tracer highlights areas of brain activity by showing how cells absorb and use glucose. The patient then rests quietly while the tracer circulates. During the scan, you’ll lie on a padded table that slides into the PET scanner. The process is painless and typically takes 30–60 minutes. At the Best Brain Imaging Facility, such as Quadra Diagnostics, the focus is on patient comfort and precision throughout the procedure.

How PET Scans Help in Diagnosis

PET brain scans can reveal reduced activity in areas affected by Alzheimer’s, detect seizure origins in epilepsy, or show tumors and inflammation in the brain. When paired with structural imaging like the Advanced CT Scan in Kolkata, doctors can map both function and anatomy, creating the most effective treatment plan. This combination ensures accurate results, which is why choosing the Best Diagnostic Centre in Kolkata is so crucial.
