Towards evidence-based emergency medicine: Best BETs from the Manchester Royal Infirmary

A short-cut review was carried out to establish whether magnetic resonance imaging (MRI) is a useful investigative tool in the diagnosis of suspected appendicitis in pregnant women. A total of 29 citations was reviewed, of which six partly answered the three-part question. The clinical bottom line is that emergency department (ED) transthoracic ultrasound is better than plain x ray in the diagnosis of pneumothorax in the supine patient. Computed tomography (CT) thorax is the gold standard for diagnosis.
