To the Editor.—  I think Dr Tizes (236:1846, 1976) will be interested in the lead articles of the October 1976 issue of Radiology,1,2 which propose that the vagus reaction is responsible for serious radiological contrast reactions (very similar to his experience on Feb 8,1975) and further describes the dramatic efficacy of atropine.Those of us who have unfortunately been confronted with this potentially disastrous, unexplainable, and unpredictable type of contrast reaction greet this new information with great interest and hope that time and further experience verify this hypothesis.
