Discrimination between pleural thickening and minimal pleural effusion using color Doppler chest ultrasonography

Egyptian Journal of Chest Disease and Tuberculosis, 2013
Background: The discrimination of pleural thickening from minimal pleural effusion may be difficult as both lesions appear as anechoic on grayscale ultrasound, hence, free of “echoes” does not confirm the presence of pleural fluid.
