When interpreting panoramic films, all are true of ghost images EXCEPT:

A. May obscure normal anatomy or be mistaken for pathologic conditions.
B. Results when the x-ray beam projects through a dense object (earring/spinal column/ramus) that is in the path of the x-ray beam but out of the portion of the focal trough being imaged.
C. Results in a projection on the same side of the radiograph with a reversed configuration.
D. Object typically appears blurred and projects over the midline structures.
