Abstract

Multiple sequences of 50 consecutive adult pelvic MRI exams were retrospectively reviewed by two radiologists to determine if opposed-phase T1 gradient echo imaging can assist in locating the normal appendix on pelvic MRI. If the appendix was visualized, it was always seen on the T2 sequence, except for one exam. The opposed-phase sequence had the second highest visualization rate, and the appendix was identified the least on the post-gadolinium sequence. The presence of a "button nose" sign was also assessed and was present in one third of cases.
