Fasting Requirements for MRI Procedures

A nurse is preparing a patient for a diagnostic imaging test known as an MRI (Magnetic Resonance Imaging). Prior to the procedure, the nurse must ensure that the patient has removed all metallic items, as these can interfere with the magnetic field.

The patient inquires about how long they should refrain from eating before the MRI. Based on standard protocols, patients generally need to avoid eating for a period of at least ______ hours prior to the test.
