Values are given as numbers of patients and percentages

The most common advantages of CTA/CTP mentioned by patients were noninvasiveness, absence of pain, and the fact that there was no need for bedrest after the test. The major disadvantages were that it was not possible to perform interventional procedures during the test and the uncomfortable position. Advantages patients attributed to CCA were the possibility of directly performing interventional measures and the diagnostic accuracy. Frequently mentioned disadvantages of CCA were the risks associated with the procedure, the long bedrest after the procedure, and the need for a compression bandage.
