2 Learning objectives Role of MR radiographers in dealing with claustrophobia in everyday MR scanning procedures is very important. MR Radiographers and other imaging professionals should be knowledgible with solutions to deal with claustrophobia, especially how to prepare the patient for examination and optimize the scanning protocol.

3 Background Claustrophobia is defined as "a fear of being in a confined or enclosed place". It is typically classified as an anxiety disorder and often results in panic attack and can be the result of many situations or stimuli, including elevators crowded to capacity, windowless rooms, and even tight-necked clothing. According to many authors claustrophobia (just as a pacemakers and metal implants) is one of the inabilities to perform MRI exam, but here is radiographers to solve the problem. Radiographers could choose or combine couple of solutions described in "Findings and procedure details" section. Images for this section: Fig. 2: Claustrophobia often results in panic attack Page 3 of 16

4 Findings and procedure details Solutions to deal with claustrophobia: 1. Optimizing the MRI exam - Reducing the exam time by choosing the most important and shorter sequences - Using parallel acquisition techniques (IPAT) - Using BLADE Motion Compensation sequences. BLADE uses special algorithms and advanced pulse sequences to decrase or eliminate motion artefact and also reduce MRI examination time. - Optimal reducing of the FoV in phase encoding directions (this will decrease acquisition time but not affect to much image quality). 2. Open MRI systems They are usually up to 0.5T and have benefits and limitations. - Benefits: greatly reduces the feeling of claustrophobia - Limitations: limited use in advanced clinical studies 3. Preparing the patient for the exam - Explaining all the procedure details telling that have the control by giving him the panic button - Having constant verbal interaction through the whole exam - Medications - level of sedation appropriate for the patient - Offer him company by family member in MRI room - Small towel placed over the eyes 4. Environment Page 4 of 16

5 - Windows within the MRI suite that provides natural light and enhances the sense of openness, - Creating sky with stars and dim ambient light that increases the sense of comfort - Using system of mirrors above the patient head, and enabling them a wider field of view MRI audio and video systems, 3D options like cinema-vision 5. Unconventional techniques - Hypnosis - a possibility in dealing with claustrophobia? - Meditation - reducing the stress and anxiety should improve the exam? 6. Future solutions - New MRI systems - with its large bore and high magnetic field (even 3T available) - New design of coils (with direct digital signal coding accelerate the acquisition time) - Specialized extremity MRI systems - smaller compact systems for scanning arms, hands, wrists, knees, ankles, etc. - New open "upright" systems that claim effective field up to 1.2T Images for this section: Page 5 of 16

14 Conclusion MR Radiographers have very important role in finding a way in minimizing symptoms from claustrophobia and making as better examination as thay can. New technical advances (machine or environment) could reduce the number of canceled MRI examinations.
