Gluscan (Fludeoxyglucose (18f))

Gluscan is injected intravenously as a sterile solution. The dose is calculated based on patient weight or body surface area, followed by a waiting period (typically 60 minutes) before PET image acquisition.

Gluscan cardiac PET imaging assesses myocardial viability, perfusion defects, and can help differentiate viable myocardium from scar tissue in patients with coronary artery disease or heart failure.

Gluscan may be used in children when clinically indicated, but dosing is adjusted for weight or surface area, and the benefit‑risk ratio must be carefully evaluated by the ordering physician.

Patients are usually asked to fast for at least 4–6 hours, maintain normal hydration, and have blood glucose measured prior to injection to ensure optimal image quality.

Gluscan is a specific brand of fludeoxyglucose (18F) formulated for injection in the EU market; its purity, sterility, and regulatory specifications may differ from other manufacturers but its imaging properties are comparable.

Common side effects include mild nausea, transient flushing, injection‑site discomfort, and occasional headache. These effects are usually short‑lived and resolve without intervention.

Gluscan is generally contraindicated during pregnancy because the radioactive fluorine‑18 may pose a risk to the fetus; it should only be used if the diagnostic benefit clearly outweighs potential harm.

Gluscan must be stored in a lead‑shielded container at controlled temperature (typically 2–8 °C) and protected from light. Personnel should follow radiation safety protocols during preparation and administration.

Standard precautions include using lead shielding, limiting time of exposure for staff, maintaining distance from the patient after injection, and monitoring radiation dose with appropriate badges.

Imaging usually begins 60 ± 10 minutes after injection, allowing sufficient tracer uptake and clearance of background activity for optimal image contrast.

Combining Gluscan with other radiopharmaceuticals in a single session is generally avoided due to potential interference; if needed, adequate time intervals between agents should be observed as per institutional protocols.
