Tc-99m exametazime (HMPAO)-labeled leukocyte scintigraphy in premature infants: detection and localization of necrotic enterocolitis and osteomyelitis

Abstract

Two cases of successful detection of inflammatory foci using Tc-99m exametazime (HMPAO)-labeled leukocyte scintigraphy in premature infants were reported. Necrotizing enterocolitis was detected in a child with a body weight of 1.6 kg. Scintigraphy confirmed a neonatal osteomyelitis in the distal part of the leg of another patient weighing 2.2 kg. These 2 cases indicate that it is feasible to perform Tc-99m HMPAO-labeled leukocyte scintigraphy even if the blood sample volume is lower than the minimal volumes required by the guidelines for pediatric patients.
