Prospective contrast-enhanced MRI and MDCT evaluation of
165 patients presenting with non-traumatic acute
abdominal pain was obtained. Two experienced
radiologists reviewed all available clinical and imaging
data to derive an image-based diagnosis. A total of
62/165 (38%) patients were diagnosed with relevant
imaging findings other than acute appendicitis. Of
these, 30/62 (48%) of patients were diagnosed with a
non-appendiceal gastrointestinal abnormality, 31/62
(50%) with a genitourinary abnormality, and 1/62 (2%)
with an extra-abdominal abnormality.
