for the ventilation study. - Answer-b. The ability to detect delayed washout
A whole body bone scan film shows a good posterior image, but the anterior view
appears diffuse and with greater soft tissue activity. What is the probable cause?
a. Wrong collimator used for the anterior
b. Increased patient to detector distance on the anterior relative to the posterior
