Indium 111 white blood cell scanning in the pediatric population
Pediatric Radiology
|January 1, 1986
Insights
Indium-111 leukocyte scans effectively detect acute infections in children, showing high sensitivity. However, specificity is moderate, indicating potential for false positives in pediatric patients.
Area of Science:
- Nuclear medicine
- Pediatric imaging
- Infectious disease diagnostics
Background:
- Indium-111 leukocyte scanning is established for adult infection detection.
- Limited data exists on its efficacy in pediatric populations.
- Accurate localization of pediatric infections is crucial for timely treatment.
Purpose of the Study:
- To evaluate the diagnostic performance of Indium-111 leukocyte scanning in children.
- To determine the sensitivity and specificity of this imaging modality in a pediatric cohort.
Main Methods:
- Retrospective review of 30 pediatric patients undergoing Indium-111 leukocyte scans.
- Analysis of scan results against confirmed diagnoses of acute infection.
- Calculation of sensitivity, specificity, and identification of false positive/negative cases.
Main Results:
- High sensitivity (94%) for detecting acute infections, with 15 out of 16 positive cases correctly identified.
- One false negative scan was observed.
- Moderate specificity (57%), with 8 true negatives and 6 false positives among the studies reviewed.
Conclusions:
- Indium-111 leukocyte scintigraphy is a sensitive tool for diagnosing pediatric infections.
- The specificity requires careful interpretation due to a notable rate of false positives.
- Further studies may refine its role in pediatric infectious disease workup.
Abstract:
Indium-111 leukocyte scanning is a reliable means of locating acute infection in adults, but its use in the pediatric population has not been extensively documented. The results of scans on 30 children retrospectively reviewed are presented. Acute infections were detected in 15 of 16 patients (94% sensitivity) with one false negative scan. There were 8 truly negative and 6 falsely positive studies (57% specificity).
