PET-CT/PET-MRI Cancer Imaging

No. The only discomfort is a small needle stick for the IV injection. The scan itself is completely painless. You simply lie still on a padded table while the scanner takes images around you.

The actual scan takes 20-40 minutes depending on the body area being imaged. PET-MRI typically takes longer (45-60 minutes) than PET-CT (20-30 minutes). Total appointment time is about 2-4 hours including preparation, injection, the 45-60 minute uptake period, and scanning.

PET-CT scanners have a wider opening (70cm bore) than traditional MRI machines, and most patients tolerate the scan well. If you have concerns, discuss with your care team beforehand. Mild sedation or oral anxiety medication can be provided if needed.

If blood glucose exceeds 200 mg/dL, the scan will need to be rescheduled. High blood sugar interferes with FDG uptake and significantly reduces image quality. Diabetic patients should work closely with their physician to optimize glucose control in the week before scanning. Afternoon appointments are often preferred for insulin-dependent patients.

The radiation dose is relatively low—similar to 2-3 years of natural background radiation (10-32 mSv for PET-CT, even lower for PET-MRI). The diagnostic benefits for cancer patients far outweigh this minimal radiation risk. The radiotracer has a short half-life (about 2 hours for FDG) and leaves your body quickly through urination.

Yes, with some simple precautions for 24-48 hours. Avoid prolonged close contact with pregnant women and young children during this period. The radioactivity level is very low and dissipates quickly—negligible by 24 hours. Normal brief interactions are fine.

Preliminary results are often available the same day in Thailand. The final written report is typically ready within 24-48 hours. Your oncologist will review and discuss the findings with you, and you'll receive a CD with images in DICOM format to share with physicians at home.

SUV (Standardized Uptake Value) measures how much radiotracer accumulates in a particular area. Higher SUV values generally indicate more metabolic activity, which may suggest cancer. However, inflammation and infection can also cause elevated SUV, so clinical correlation with your medical history and other tests is essential for accurate interpretation.

Lower operating costs, facility overhead, and streamlined hospital systems allow Thai hospitals to offer the same advanced imaging at 50-85% less than US prices. There's no compromise on quality—major facilities are JCI-accredited, use the same equipment as top US medical centers, and follow IAEA and SNMMI/EANM international standards.

Yes. JCI-accredited hospitals provide reports that meet international standards. Images are provided in DICOM format, which is compatible with any medical imaging system worldwide. Reports are written in English using standardized medical terminology. Most physicians readily accept results from internationally accredited facilities.
