What do I do if I am claustrophobic?

PET scans can be difficult for some patients with claustrophobia. The “tube of a PET scanner is not as tight and long as an MRI but is lightly longer than of a CT machine. The tube is open on both ends and the room as a very large window overlooking trees. Most patients have no issues with it.

Below are some techniques that we found helpful in reducing some of the anxiety associated with claustrophobia:

• Talk to us beforehand: Fear about scans and claustrophobia are relatively common. By making us aware of your apprehension early on, we can work together to create a plan to reduce your distress and improve the experience.

• Listen to music: It’s astounding how much of a difference the use of music can make to reduce stress in an anxiety-provoking situation. We can play calming music that will allow your mind and body to relax. Alternatively you can chose your favorite tunes that give you comfort.

• Focus on breathing: Focused attention on deep, slow breathing can create a physiological and psychological response that relaxes the body and mind. Using mindful meditation skills as part of your PET scan can also be a helpful strategy.

• Cover your eyes as soon as you lay down on the table, before the table moves: It may seem like this is an overly simplistic suggestion, but sometimes such a simple act can make a huge difference when it comes to managing anxiety. Consider picturing some guided imagery. Conjure a peaceful scene and then imagine the details in your mind’s eye. Imagine you are lying on the beach for example. You might be surprised how relaxing this exercise can be.

• Bring a friend for support: Inviting a friend to support you during the scan can be a soothing and healthy distraction from the task at hand. If you are reluctant to ask, remember that you may be asked to reciprocate some day and your friend would probably be glad to help.

• Count: The use of counting as a distraction technique is simple, easy and practical. Focusing on the numbers will shift the focus away from the procedure. If you want even more complex distraction, work on some math problems in your head!

• For some patients with strong worries about the scan it has helped in the past when they came in and visited us a few days prior to the actual scan and do a “dry run” and lie on the table.

• Ask for sedation: Many mild medications can be taken before procedures. Short-acting sedative drugs such as the benzodiazepine Xanax, Ativan, or Valium may be an option to discuss with your doctor if your claustrophobia is severe. If so, you will take this medication prior to your exam, according to your doctor's instructions.

Claustrophobia is relatively common, particularly with imaging-tests such as MRI, CT and PET scans that involve enclosed spaces. Simple management techniques can help make the experience less stressful.

Regardless of what claustrophobia management techniques you use, don’t hesitate to share your thoughts and feelings with your referring physician as well as Dr. Riedl and the technician at ImagingWest prior to having your PET scan done.
