Caption
B-lines are vertical artifacts that moves with respiration from the pleural surface. They represent increased water in an area of the lung. In the right clinical context this could represent pulmonary edema. An increase in B-lines correlates with the degree of pulmonary edema. Keep in mind that in different clinical contexts, they can represent different diagnoses including pulmonary contusions and pneumonia. Justin Bowra MBBS, FACEM, CCPU Emergency Physician, RNSH et al.
