Roentgen examination is not an Aladdin's lamp but an exact science, mathematically governed. Unfortunately the mathematics are complicated by the human equation, and this discussion is an attempt to remove some of the variables from this equation.
The errors which I shall describe are those which I have found to be made most commonly by the surgeon who reads his own films without consulting with the roentgenologist and will serve to emphasize my request for a more personal touch between the surgeon and the roentgenologist.
It would be wise for the surgeon to read the report of the roentgenologist and then examine the films and form his own opinion. If there is a discrepancy, the roentgenologist should be consulted, and possibly he can explain the reason that the two opinions do not agree. There are factors in the technic, the history and the clinical findings
