Is PET-CT done only when cancer is confirmed?
This is a common misconception.
While PET-CT gained prominence in oncology, its clinical applications extend far beyond cancer diagnosis and staging. Initially developed to evaluate brain function, PET-CT continues to play a crucial role in assessing neurological conditions.
Today, it is also widely used to:
* Identify hidden sources of infection in patients with prolonged fever
* Evaluate unexplained, persistent weight loss
* Assess cardiac viability
* Diagnose and monitor conditions such as cardiac sarcoidosis
PET-CT is a powerful functional imaging tool that helps clinicians detect metabolic changes early often before structural changes become visible.
Understanding its broader applications enables timely diagnosis, accurate treatment planning, and improved patient outcomes.
