6. What if I am claustrophobic - can the CT scan procedure heighten my Claustrophobia?
Generally MRI procedures cause much more problems with claustrophobia then CT scan procedures.
However if you suffer from claustrophobia the CT scan procedure can make you more anxious. If you are concerned, it maybe best to do some breathing exercise or consult your psychiatrist before the procedure. Sometimes drugs may help calm down your nerves. The good thing about CT is that the procedure takes only one to five minutes. Also the CT tube is wider and during the test the table moves and you are not just lying still.
MRI procedure can take 30 to 40 minutes and you have to lie still on the table, hence the aggravation of claustrophobia is much more.
