Radiology is not always serious stuff!!
This is how some of us (not all) define things!
laugh a lil..........
Barium: - What you do when they're dead
Cystogram: - an email sent to your sister
Isodense: - Radiography student after sitting finals
Pleural: - More than one
Sacral: - Holy
Sella: - A good place to keep your wine.
