Purpose of the Procedure
- Determine the extent of radiopharmaceutical leakage from the liver to the lungs.
- Calculate the Lung Shunt Fraction (LSF) to ensure patient safety.
- Enable the medical team to calculate the appropriate radiation dose for SIRT.
Book Pre-SIRT Lung Scan in Saudi Arabia | Lahalak Medical Platform
A vital nuclear imaging procedure performed before Selective Internal Radiation Therapy (SIRT) to calculate the lung shunt fraction, ensuring radiation safety and treatment precision for liver cancer patients.
Scientific name: Tc-99m MAA Lung Perfusion Scintigraphy (Pre-SIRT)
A nuclear medicine scan using Tc-99m MAA to evaluate lung perfusion and calculate the lung shunt fraction. It ensures safe dosage for SIRT therapy by preventing unintended radiation exposure to the lungs.
