Cover Story: A key issue in abdominal US is the assessment of fluid, which is usually anechoic, thus appearing “black”. The “black” pattern fluid assessment is based on a three-step analysis: 1. look for black where it should not be. This means searching for effusions or collections. 2. Check if black is too much. This means evaluating anatomical landmarks where fluid should normally be present but may be abnormally abundant. 3. Look for black that is not clearly black. This means evaluating fluid aspects, whether wholly anechoic or not (suggesting heterogeneous or corpusculated fluid). Using this simple method focused on US fluid presence and appearance should help clinicians to make a timely diagnosis. View this paper
