The importance of Roentgen examinations of the lungs is well expressed by the statement of Dr. Judson A. Daland, who says: "No chest examination is complete without an x-ray examination." In order to make Roentgen examinations of the greatest possible value, the best technic and the most careful and accurate interpretation must be employed.
As specialists in this special branch of medicine, we have made great strides in the perfection of our technic, but even with the most perfect technic in the making of a negative, much general knowledge of medicine, and much experience is still needed to interpret accurately the shadows obtained. Much assistance can be obtained from the study of the literature, but much more can be learned by the actual study of the negatives of the various pathologic conditions, associated with the clinical or the postmortem findings.
Postmortem examinations are seldom made immediately after the Roentgen examination,
