Abstract
Purpose: Very-low-birth-weight (VLBW) infants are more likely to have poor neurodevelopmental outcomes, even if structural abnormalities are not observed during brain magnetic resonance imaging (MRI). The purpose of the present study was to determine whether cerebral glucose metabolism is correlated with neurodevelopmental outcomes in VLBW infants without structural abnormalities.
Methods: Twenty-seven VLBW infants (birth weight < 1,500 g) without structural abnormalities were prospectively enrolled. All infants underwent F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) examinations at term-equivalent ages, and the regional glucose metabolic ratios were calculated. Neurodevelopmental outcomes were assessed using the Mental Development Index (MDI) and the Psychomotor Development Index (PDI) of the Bayley Scales of Infant Development-II at a corrected age of 18-24 months. Poor neurodevelopmental outcomes were defined as an MDI or PDI score < 85.
Results: The glucose metabolic ratio in the right central region of the brain was significantly correlated with the MDI score (r = 0.505, p = 0.007). The glucose metabolic ratios in the right central region and right insula in the poor-neurodevelopmental-outcome group were significantly lower than those in the good-neurodevelopmental-outcome group (1.03 ± 0.02 vs. 1.08 ± 0.04, p = 0.004, and 1.08 ± 0.05 vs. 1.13 ± 0.05, p = 0.018, respectively). Furthermore, the right central region and insula exhibited large extent of metabolic connectivity in infants with good neurodevelopmental outcome than that in infants with poor neurodevelopmental outcome.
Conclusions: Cerebral glucose metabolism was correlated with the neurodevelopmental outcomes of VLBW infants at a corrected age of 18-24 months.

期刊介绍:
Nuclear Medicine and Molecular Imaging (Nucl Med Mol Imaging) is an official journal of the Korean Society of Nuclear Medicine, which bimonthly publishes papers on February, April, June, August, October, and December about nuclear medicine and related sciences such as radiochemistry, radiopharmacy, dosimetry and pharmacokinetics / pharmacodynamics of radiopharmaceuticals, nuclear and molecular imaging analysis, nuclear and molecular imaging instrumentation, radiation biology and radionuclide therapy. The journal specially welcomes works of artificial intelligence applied to nuclear medicine. The journal will also welcome original works relating to molecular imaging research such as the development of molecular imaging probes, reporter imaging assays, imaging cell trafficking, imaging endo(exo)genous gene expression, and imaging signal transduction. Nucl Med Mol Imaging publishes the following types of papers: original articles, reviews, case reports, editorials, interesting images, and letters to the editor.
