A member asked:

Hi, can iodine ct scan miss 2 cm aneurysm ? i guess it can seem a weird question with a obvious no but i d like to be sure. thanking you in advance.

Brain Aneurysm: I assume you mean brain aneurysm, in which case the answer is no. A 2cm aneurysm is very large and will be easily detected by contrasted ( or non/contrast) ct scan. If by chance you are mistaken and mean 2millimeter, not centimeter, it is very easy for a ct to miss.

Dr Wright and another doctor agreed
