Controlled Area

Answer this...

What area is the Controlled Area?

The MRI department is a Controlled Area, and all those who enter the Controlled Area should complete a screening questionnaire. No person who has a cardiac pacemaker may enter the controlled area. Some departments distinguish outer and inner controlled areas. The outer controlled area is restricted for persons with pacemakers. The inner controlled area is usually the magnet room itself and denotes the area within which the projectile effect poses a significant risk. Anyone entering it should be accompanied by an Authorised Person.

MRI departments will have their own set of Local Rules, which should be read by all staff who have access to the department. These guidelines are department-specific information about the controlled areas, the designated Responsible Person, and Authorised Personnel.
