Segregation of risk groups of patients

Aerosol generating procedures, e.g. ventilation portion of V/Q scan	Temporarily halted. Radionuclide perfusion only scan for urgent cases. Non-urgent requests postponed.
Exercise stress for myocardial perfusion imaging	Converted to pharmacological stress if possible.
Segregation of inpatients and outpatients	Where possible, one scanning room designated for inpatients. If physical segregation not possible, temporal segregation (inpatients after all outpatients) done.
Hybrid imaging with CT component	CT images of lungs screened before allowing patients to leave the department. Referring clinician informed if suspicious CT changes detected.
