What is the minimum dosage range for the 18F-Choline procedure?

For the 18F-Choline procedure, the minimum dosage range typically recommended is 5-7 mCi. This range is considered optimal for ensuring sufficient uptake for imaging while maintaining patient safety. 18F-Choline is a radiopharmaceutical commonly used in the evaluation of prostate cancer, particularly for detecting disease recurrence and metastasis due to its biological behavior that allows it to target areas of increased cellular metabolism.

Using a dosage within this range enhances the sensitivity and specificity of the PET imaging results. Lower dosages might not provide adequate imaging quality, while higher doses could expose the patient to unnecessary radiation without improving diagnostic quality. Therefore, the 5-7 mCi range is balanced to achieve effective imaging results while adhering to safety protocols.
