Question

A WBS bone scan film shows a good posterior image, but the anterior view appears diffuse with greater soft tissue activity. what is the probable cause?

a. wrong collimator used for anterior
b. increased patient to detector distance on the ant relative to the post
c. low tagging efficiency of the RP
d. patient was not sufficiently hydrated
e. none of the above

Answer 1

The probable cause for the diffuse and greater soft tissue activity seen in the anterior view of the WBS bone scan film could be due to increased patient to detector distance on the anterior view relative to the posterior view.

Step-by-step explanation:

The probable cause for the diffuse and greater soft tissue activity seen in the anterior view of the WBS bone scan film could be due to increased patient to detector distance on the anterior view relative to the posterior view. When the distance between the patient and the detector is greater, there is a potential for more scattered radiation, leading to a diffuse and less clear image.
