A radiograph is acquired using 12.5 milliampere-seconds (mAs) at a 40-inch source-
to-image distance (SID) and results in excessive magnification If the SID is change to
80 inches, what new mAs should be used to maintain image receptor exposure?
Give this one a try later!
50 mAs

Consider this scenario: The director of the radiology department is brought to the
emergency department unconscious following a severe motor vehicle accident. After
a CT head is performed, the radiology staff gathers around the Picture Archiving and
Communication System (PACS) monitor to view the images. Is this a breach of the
HIPAA law?
