Scanner Technology

The United Imaging uMI550

Dr. Mukhtar's Imaging Centre proudly introduces J&K's first Digital PET-CT scanner. Unlike legacy analog scanners, which rely on vacuum-tube photomultipliers, our uMI550 utilizes **Digital Silicon Photomultiplier (SiPM) detectors**.

This advanced chip-based detection system increases diagnostic sensitivity. By collecting data in 80-slice CT scans, it captures highly detailed diagnostic signals. This enables early identifying of cancer nodules down to sub-1.5 mm voxel scales.

Key Patient Benefits:

50% Lower Radiation: Higher detection sensitivity means patients require only half the radio-tracer dose compared to analog scans.

5-6 Minute Scan: Faster scans lower claustrophobia and reduce motion-blur.

Scan Classifications

PET-CT Scan Varieties Available

Different radiopharmaceuticals target specific cellular receptors, helping in high-precision oncology staging.

FDG PET-CT Scan

Fluorodeoxyglucose (FDG) is the most common diagnostic tracer. Since active cancer cells consume glucose rapidly, FDG highlights metabolic hotspots, aiding in staging and post-chemotherapy assessment.

PSMA PET-CT Scan

Prostate-Specific Membrane Antigen (PSMA) mapping is a highly specialized scan for prostate cancer. It is highly sensitive, detecting microscopic recurrences even at low, rising PSA levels.

DOTANOC PET-CT Scan

DOTANOC imaging binds specifically to somatostatin receptors on neuroendocrine cells. It is the gold standard for identifying, staging, and monitoring neuroendocrine tumors (NETs).

Preparation Guide

Patient Guidelines for PET-CT

Adhering strictly to these rules is vital to ensure clear, readable molecular diagnostic scans.

24 Hours Prior to Your Scan

Diet: Stick to a high-protein, low-carbohydrate diet. Avoid foods containing sugars and carbohydrates (bread, rice, pasta, potatoes, sweets, soft drinks, fruits, and milk). Eat meats, fish, eggs, cheese, and non-starchy vegetables.
Physical Activity: Strictly avoid strenuous exercise, heavy lifting, running, or gym workouts, as active muscle tissue will rapidly absorb the FDG tracer, creating scan artifacts.
Hydration: Drink plenty of plain water throughout the day.

On the Day of Your Scan

Fasting: Fast for at least 6 hours prior to your scheduled slot. Do not eat anything, and do not drink tea, coffee, milk, or sweetened beverages. Only plain water is permitted.
Medications: You may take your standard chronic medications with plain water, except for cough syrups or diabetic treatments (please review the diabetic tab).
Attire: Wear comfortable, warm clothing without metal buttons, zippers, or underwires. Leave jewelry, watches, and piercings at home.
Punctuality: Arrive 30 minutes prior to your slot. The radio-tracer is calibrated individually and decays rapidly; delays can compromise the study.

Special Instructions for Diabetic Patients

Since PET-CT scans trace glucose analog (FDG), your blood glucose level must be within safe margins (ideally under 150-180 mg/dL) at the scan time. High blood sugar will compete with the tracer, blurring the images.

Oral Medication: You may take your oral diabetic medicines (metformin, etc.) as usual, up to 4 hours before the scan.
Insulin: Do not take insulin injections within 4 hours of your scan. Coordinate with our desk to schedule an early morning scan to safely manage your fasting.
Notify our radiologists of your diabetes status immediately when booking.

Post-Scan Guidelines

Hydration: Drink 1.5 to 2 liters of water over the next 24 hours to help flush the diagnostic radioactive tracer from your kidneys.
Safety Isolation: The radioactive tracer decays rapidly. However, as a precaution, avoid close contact or hugging pregnant women and children for 12 to 24 hours after the scan.
Lactation: Breastfeeding patients should express and discard milk for 24 hours post-scan before resuming standard nursing.

FAQ

PET-CT Scan FAQs

Common questions regarding the clinical safety and logistics of PET-CT imaging in J&K.

Is the radioactive tracer injection safe? Are there side effects?

Yes, it is highly safe. The radioactive tracer (such as FDG) has a short half-life (approx. 110 minutes) and leaves the body rapidly via urination. It is not a contrast dye, so allergic reactions are extremely rare. The radiation dose is minimal, especially when using our Digital uMI550 scanner, which reduces the required tracer amount by half.

How long does the entire appointment take?

While the actual scanning in our digital uMI550 scanner takes only 5-6 minutes, the entire visit takes about 2 to 2.5 hours. Upon arrival, you will receive the tracer injection and rest quietly in an uptake room for about 60 minutes, allowing the tissues to absorb the tracer, before you lie down on the scanner table.

Can a PET-CT scan be performed on pregnant or breastfeeding women?

PET-CT is generally contraindicated during pregnancy unless the diagnostic benefits heavily outweigh radiation risks. Breastfeeding mothers can undergo the scan but must express and discard milk for 24 hours post-procedure before resuming normal nursing.
