(medicine, radiology, historical) A specific type of clinicoradiopathologic conference that was used in the early decades of radiography (circa 1900 until World War I), whereby practitioners would make a radiologic diagnosis and then systematically compare it with the subsequent clinical course and any surgery, intraoperative or postoperative radiography or fluoroscopy, and/or autopsy. This method helped advance radiology, given that it is inherently a field of discerning clinicoradiological and clinicoradiopathological correlations. It is no longer codified under this name, because it is no longer necessary in routine practice.
