b. Lungs filled with air give a clearer picture.
c. It decreases the error caused by motion.
d. It makes the heart appear larger.
B
A radiograph is taken when the patient has taken a deep breath (inspiration). During exhalation, the lungs are less full of air, which can make the lung tissue appear "cloudy" as if there is additional lung water. The heart also appears larger during exhalation. This could lead to an erroneous diagnosis of heart failure.
