Title: Scintigraphic manifestations of infraction of the second metatarsal (Freiberg's disease). Author: Mandell GA, Harcke HT. Journal: J Nucl Med; 1987 Feb; 28(2):249-51. PubMed ID: 3806228. Abstract: Two patients with Freiberg's infraction of the second metatarsal are presented. The scintigraphic pattern of a photopenic defect with hyperactive collar is demonstrated as evidence of the existence of avascular necrosis or infarction in this entity. The photopenia was appreciated only on pinhole collimator images in our first patient. The later revascularization phase of avascular necrosis with diffuse increase in uptake is demonstrated scintigraphically in the second patient.[Abstract] [Full Text] [Related] [New Search]
