Question

Quizplus · Accepted Answer

CT is the best imaging modality to differentiate an abscess from bowel gas as it allows for clear visualization of the soft tissue and can differentiate between fluid collections and air-filled structures. MRI can also differentiate between fluid collections and bowel gas, but it is less commonly used for this purpose. Plain film and ultrasound are less reliable in differentiating between abscess and bowel gas.
