If you or your loved one has recently been advised to undergo a PET scan for cancer detection, you're likely searching for answers. What exactly is a PET scan? How does it detect cancer? Is it safe? Most importantly, where can you get the most accurate and affordable PET scan in Hisar?
You’ve landed at the right place.
In this comprehensive guide, we’ll walk you through everything you need to know about PET scans, especially their role in cancer detection. We’ll also explain why Sarvesh Health City is considered the top PET scan hospital in Hisar and how we’re helping hundreds of patients with advanced imaging diagnostics.
🧠 What Is a PET Scan?
PET stands for Positron Emission Tomography. It is an advanced imaging technique that allows doctors to observe the metabolic processes inside the body. Unlike a regular CT or MRI scan that focuses on structure, a PET scan highlights how tissues and organs function.
A small amount of radioactive tracer (commonly a form of glucose) is injected into the patient. Cancer cells, which are often more metabolically active, absorb more of this tracer and show up as “hot spots” on the scan.
🎯 Why Is a PET Scan Used for Cancer?
PET scans are powerful because they reveal what other scans often miss. Here's how they help in cancer:
-
Early Detection: Cancerous tissues can be detected before physical symptoms appear.
-
Staging the Cancer: Helps identify whether cancer has spread to lymph nodes or other organs.
-
Treatment Monitoring: Evaluates how well the body is responding to chemotherapy or radiation.
-
Detecting Recurrence: Identifies whether cancer has returned after treatment.
In short, PET scans detect cancer by targeting the metabolic activity of cells, giving doctors a real-time map of what’s happening inside.
⚙️ How Does a PET Scan Work?
Here’s a simplified breakdown:
-
A small amount of radioactive tracer (usually FDG - Fluorodeoxyglucose) is injected into your bloodstream.
-
You wait for 30–60 minutes as the tracer circulates and is absorbed by your tissues.
-
You lie down on a scanning bed that slides into the PET machine.
-
The scanner detects radiation from the tracer and produces 3D images.
-
The areas with high metabolic activity (often cancerous cells) appear brighter.
Cancer cells love sugar, and since FDG mimics glucose, these cells soak it up faster than normal ones, making them glow on the scan.

🔬 What Types of Cancer Can PET Scans Detect?
PET scans are commonly used to detect and monitor:
-
Lung Cancer
-
Breast Cancer
-
Lymphoma
-
Colorectal Cancer
-
Esophageal Cancer
-
Melanoma
-
Thyroid Cancer
-
Cervical and Ovarian Cancers
-
Head and Neck Cancers
-
Brain Tumors
Not every type of cancer requires a PET scan, but it’s especially effective in cancers that are aggressive or have the potential to spread quickly.
🧪 How Safe Is a PET Scan?
Many people worry about the radioactive tracer, but the dose used in a PET scan is very small. The tracer decays quickly and leaves the body naturally within a few hours.
Key safety points:
-
Non-invasive and generally painless
-
No long-term radiation risk
-
Usually avoided during pregnancy or breastfeeding, unless necessary
If you have concerns, our radiology experts at Sarvesh Health City will guide you through every precaution.
⏰ How Long Does a PET Scan Take?
The entire process usually takes 2 to 3 hours:
-
Preparation & tracer absorption: 30–60 minutes
-
Scan time: 30–45 minutes
-
Post-scan rest: 15–30 minutes, if required
You’re typically allowed to go home the same day. Make sure to stay hydrated afterward to flush the tracer from your system.
🥗 What Should You Do Before and After a PET Scan?
Here are some preparation tips:
Before the Scan:
-
Avoid food for at least 6 hours before the scan
-
Stay hydrated
-
Avoid strenuous activity the day before
-
Inform your doctor if you're diabetic, pregnant, or on any medication
After the Scan:
-
Drink plenty of water
-
Avoid close contact with pregnant women or infants for a few hours
-
You can usually resume normal activities the same day
Following these steps ensures accurate results and your own safety.
🔍 PET Scan vs. CT Scan vs. MRI: What’s the Difference?
| Feature | PET Scan | CT Scan | MRI |
|---|---|---|---|
| Focus | Metabolic Activity | Structural abnormalities | Soft tissue and brain details |
| Tracer Use | Yes (radioactive sugar) | No | No |
| Radiation | Yes | Yes | No (uses magnetic field) |
| Best For | Cancer, heart, brain function | Injuries, bone issues | Brain, spinal cord, muscles |
For cancer detection and treatment monitoring, PET-CT scans offer the best of both worlds—function and structure in one test.
📈 How Accurate Are PET Scans in Detecting Cancer?
PET scans are highly accurate, especially when combined with CT (known as PET-CT). However, false positives and negatives can occur in certain scenarios. That’s why clinical correlation with biopsy and other tests is always recommended.
Accuracy improves with:
-
High-quality imaging equipment (like at Sarvesh Health City)
-
Expert radiologist interpretation
-
Patient compliance with prep instructions
