Radiologists and informed-consent lawsuits.

A national survey on informed-consent lawsuits that resulted from studies using contrast material revealed that 123 (8%) of 1,513 radiologists surveyed or others in their groups had been involved in informed-consent lawsuits. In response to a detailed follow-up questionnaire, 67 radiologists anonymously provided additional information regarding their lawsuits, which most often involved excretory urography (37%) or angiography (38%), with death or neurologic impairment the most common patient injuries. As a result of these lawsuits, many radiologists provide more detailed information to patients. In the United States, the total number of informed-consent lawsuits, however, was small in relation to the total number of studies done using contrast material.
