Description
Why It’s Done:
• To detect prostate cancer recurrence, especially when PSA levels rise after treatment.
• To evaluate metastasis or the spread of prostate cancer to lymph nodes, bones, or other organs.
• To assist in treatment planning by identifying precise tumor locations.
• To compare with prior imaging studies for disease monitoring or response assessment.
Preparation:
• Fasting: You may be asked to avoid food and drink (except water) for 4–6 hours prior to the scan.
• Hydration: Drink plenty of water before the scan to help flush the tracer from your body afterward.
• Medications: Inform your doctor of any medications you are taking. You can usually take them unless instructed otherwise.
• Avoid physical exertion: Refrain from strenuous physical activity for 24 hours before the test.
• Medical history: Bring prior imaging reports or scans if they’re being used for comparison.
• Allergies and medical conditions: Inform the healthcare provider if you have kidney problems, diabetes, or allergies to contrast material.
• Clothing: Wear comfortable, loose-fitting clothing; you may be asked to change into a gown for the scan.
• Pregnancy and breastfeeding: Notify your doctor if you are pregnant or breastfeeding.
