Predictive Role of Urinary Metabolic Profile for Abnormal MRI Score in Preterm Neonates

Table 2

MRI classes, using the Kidokoro MRI score, in the study group. Abbreviations: WM: white matter; cGM: cortical grey matter; DGM: deep gray matter; PLIC: posterior limb of the internal capsule; CR: corona radiata; IHD: interhemispheric distance; cTCD: coronal transverse-cerebellar diameter.
