Due to the condition of the patient and the equipment required unexpected delays in leaving the ward area for imaging are sometimes unavoidable. • Minimize the time the unstable patient needs to spend within the department. Pre imaging • Assess the risks and benefits of imaging each unstable patient individually. g. a patient with respiratory distress may be unable to lie flat) and the likely yield from the investigation. • Patients should be stabilized prior to transfer to the radiology department whenever possible.
