| Here we see a right lateral decubitus X-ray showing a large
pleural effusion, typical of DHF the day after defervescence.
When the chest X-ray is taken in this position, with the patient
resting on the right side, the degree of plasma leakage may
be quantified by means of the pleural effusion index. The
pleural effusion index is calculated as 100 times the maximum
width of the right pleural effusion, divided by the maximal
width of the right hemithorax. |
