  1. MRI Industry: Review of Proposed Accessibility StandardsMilind Dhamankar MDU.S. Access BoardMay 8, 2012Atlanta, Georgia

  2. MR Physics Made Easy 65 % H2O MRI made simple U N S Magnet Radio Frequency energy Hydrogen protons Computer to reconstruct images

  3. Ferrous materials within magnet room is a hazard! Safety precautions, training, hazard signs and being alert will help reduce the risk!

  4. Diagnostic Equipment – MRICurrent State • Appropriate ergonomic design and patient accessibility features are goals for all MRI equipment manufacturers • Per US FDA / EU MDD, manufacturers are required to address MRI human factors and usability • All items entering MR magnet room must be known to be either MR safe or MR conditional labeled

  5. Chapter M3: MRI M301.2 / 305.2: Transfer Surface – Height 17-19 inches, Size:30 inches wide, > 250 lbs horizontal and vertical movement M301.4 Lift Compatibility: Free standing overhead track lift may be an issue – MR compatible Hoyer lifts are possible Some features and clearances currently comply, but further assessment of certain proposed requirements in the context of MR applications is required.

  6. Need Easier patient transfer to MRI table “MRI conditional” transport systems to facilitate safe patient transfer to MRI table Bigger, lighter and more open RF coils Current Approach Most MRI systems have motorized vertical (19 inch low) table movement. “MRI conditional” wheel-chair, transport trolley, patient transport shells are available MRI table tops have patient positioning cushions, safety straps, side rails, iv stand holders and emergency pull–out mechanisms Newer high-density, ultra-light coils come in all sizes ranging from extra-small loop coils to XXL body coils. Accommodating Patients With Special Needs

  7. Need Need improvement in patient communication during MRI exam Current Approach Current MR systems comply with this requirement Patient communication unit Intercom communication with the patient Patient alert system (squeeze-bulb) Volume of speaker in control room Connection to external audio system No radiation in MRI allows presence of patient relative / help next to the patient to coordinate tactile communication Patient CommunicationAdvisory M306.1
