As a medical professional with extensive experience in nuclear medicine, I’ve seen countless patients benefit from the Sesta Mibi parathyroid thyroid scan. This advanced diagnostic tool has revolutionized how we detect and treat parathyroid disorders in cities like Nagpur
The Sesta Mibi scan represents one of the most accurate methods for identifying problematic parathyroid glands. In my practice, I’ve witnessed its remarkable ability to pinpoint even the smallest adenomas that other tests might miss
What is Sesta Mibi Parathyroid Thyroid Scan
The Sesta Mibi parathyroid thyroid scan is a specialized nuclear medicine procedure that uses a radioactive tracer called Technetium-99m Sestamibi. This procedure localizes parathyroid adenoma, which causes hyperparathyroidism, allowing surgeons to use minimally invasive surgical approaches
I often explain to my patients that this scan acts like a GPS for surgeons. It creates detailed images showing exactly where the problematic parathyroid tissue is located
The scan works by injecting a small amount of radioactive material that gets absorbed by overactive parathyroid glands. These glands then appear brighter on the scan images, making them easy to identify
Understanding How the Scan Works
The science behind this scan is fascinating yet simple to understand. The Sestamibi tracer has an affinity for mitochondria-rich cells, which are abundant in overactive parathyroid tissue
When I perform this scan, the tracer accumulates in areas with high metabolic activity. Abnormal parathyroid glands typically have increased blood flow and cellular activity, making them stand out clearly
The procedure involves injecting radiotracers into a vein, followed by special camera imaging of the parathyroid glands. The entire process is painless and takes about 2-3 hours to complete
When Do You Need This Scan
During my years of practice, I’ve identified several key situations where this scan becomes essential. The most common reason is suspected hyperparathyroidism
Primary Indicators Include
High calcium levels in blood tests often prompt me to recommend this scan. Many patients come to me with symptoms like kidney stones, bone pain, or unexplained fatigue
Persistent bone disease despite normal vitamin D levels is another red flag. I’ve seen patients struggle with osteoporosis that doesn’t respond to conventional treatment
Specific Medical Conditions
Primary hyperparathyroidism affects about 1 in 1000 people annually. The condition causes excessive parathyroid hormone production, leading to calcium imbalance
Secondary hyperparathyroidism often develops in patients with chronic kidney disease. This scan helps determine if parathyroid glands have become autonomous
Parathyroid adenomas are benign tumors that cause most hyperparathyroidism cases. The scan can locate these small growths with remarkable precision
Preparing for Your Scan
Proper preparation ensures accurate results and a smooth experience. I always provide my patients with detailed pre-scan instructions
Dietary Guidelines
Stop taking calcium supplements 48 hours before the scan. This includes multivitamins containing calcium and calcium-fortified foods
Avoid caffeine on the day of your scan. Coffee, tea, and energy drinks can affect tracer uptake
Medication Considerations
Inform your doctor about all medications you’re taking. Some drugs can interfere with scan accuracy
Heart medications, particularly those containing digitalis, may need temporary adjustment. Never stop medications without consulting your physician
Day of the Scan
Arrive 30 minutes early for paperwork and preparation. Wear comfortable clothing without metal buttons or zippers
Remove all jewelry, especially necklaces and earrings. These items can interfere with imaging
The Procedure Step-by-Step
I want to walk you through exactly what happens during your scan, as understanding the process reduces anxiety
Initial Preparation
You’ll be taken to a comfortable room where a technologist will explain the procedure. An IV line is placed in your arm for tracer injection
A dose of 740 to 925 megabecquerel of sestamibi is injected intravenously, which sounds scary but is actually very safe
Imaging Process
The first images are taken 15-20 minutes after injection. You’ll lie on a table while a special gamma camera rotates around your neck
Most patients find the imaging comfortable. The camera doesn’t touch you, and you can listen to music during the procedure
Delayed Imaging
Additional images are taken 2-3 hours later. This delay allows normal thyroid tissue to clear the tracer while abnormal parathyroid tissue retains it
The contrast between normal and abnormal tissue becomes most apparent during these delayed images

Understanding Your Results
Interpreting scan results requires medical expertise, but I believe patients should understand the basics
Normal Results
A normal scan shows symmetric uptake in thyroid tissue with no focal areas of increased activity. The parathyroid glands typically aren’t visible on normal scans
Abnormal Findings
Increased uptake in a specific area suggests parathyroid adenoma or hyperplasia. The location and intensity help determine the next treatment steps
Sensitivity of MIBI scan for parathyroid localization ranges from 72.1% to 73.6%, making it highly reliable for diagnosis
What Results Mean for You
Positive results usually lead to surgical consultation. The scan provides surgeons with a roadmap for minimally invasive procedures
Negative results don’t rule out parathyroid disease. Additional testing or alternative imaging may be necessary
Cost Analysis and Insurance Coverage
Understanding the financial aspects helps patients plan for this important diagnostic test
Average Costs in Nagpur
The cost typically ranges from ₹8,000 to ₹18,000 depending on the facility and additional services required
Private hospitals generally charge more but may offer shorter wait times and additional comfort amenities
Insurance Considerations

Safety Profile and Risk Assessment
Safety concerns are natural when dealing with radioactive materials. Let me address these concerns based on scientific evidence
Radiation Exposure
The radiation dose from this scan is minimal – equivalent to about 6 months of natural background radiation. This level poses no significant health risk
Tc99m Sestamibi is a very safe and mild radioactive agent that clears from your body within 24-48 hours
Common Side Effects
Most patients experience no side effects. Rarely, some may feel slight discomfort at the injection site
Allergic reactions to the tracer are extremely rare. The contrast agent doesn’t contain iodine, reducing allergic potential
Special Populations
Pregnant women should avoid this scan unless absolutely necessary. The radiation, while minimal, could potentially affect fetal development
Breastfeeding mothers may need to temporarily stop nursing for 24 hours after the procedure
Alternative Diagnostic Methods
While Sesta Mibi scanning is highly effective, other diagnostic options exist for specific situations
Ultrasound Comparison
Neck ultrasound is less expensive and doesn’t involve radiation. However, it’s operator-dependent and may miss small adenomas
Ultrasound sensitivity for parathyroid localization varies from 57.0% to 70.9%, making it less reliable than Sesta Mibi scanning
CT and MRI Options
Four-dimensional CT scanning provides excellent anatomical detail but involves higher radiation exposure
MRI offers superior soft tissue contrast without radiation but is more expensive and time-consuming
When Sesta Mibi is Preferred
For preoperative planning, Sesta Mibi remains the gold standard. It provides both functional and anatomical information
Patients with previous neck surgery benefit most from this scan, as it can identify ectopic parathyroid tissue
Recovery and Post-Scan Care
The recovery process is straightforward, but following proper guidelines ensures optimal results
Immediate Post-Scan
You can resume normal activities immediately after the scan. No special restrictions apply to most patients
Drink plenty of fluids to help eliminate the tracer from your system. Water is the best choice for hydration
Follow-up Timeline
Results are typically available within 24-48 hours. Your doctor will schedule a follow-up appointment to discuss findings
If surgery is recommended, scheduling usually occurs within 2-4 weeks of the scan
Long-term Monitoring
Patients with positive results need regular follow-up even after treatment. Blood calcium levels require periodic monitoring
Those with negative results may need repeat scanning in 6-12 months if symptoms persist
Expert Tips and Recommendations
Drawing from my extensive experience, here are key insights that can improve your scanning experience
Preparation Mistakes to Avoid
Don’t stop taking prescribed medications without medical approval. Some patients make this error, thinking all drugs interfere with scanning
