Fetuses who are small for gestational age (SGA) are undernourished and at increased risk of neonatal morbidity. Due to limited nutrient supply, they exhibit a leaner body composition. Fat accretion during late gestation follows a craniocaudal and centripetal pattern, first visible in the cheeks, with the fastest accumulation in the upper limbs. This study aimed to characterize regional variations in fetal fat accretion in SGA compared with appropriate-for-gestational-age (AGA) controls across SGA subgroups by onset (early vs. late) and cerebroplacental ratio (CPR; abnormal vs. normal), and to examine associations with neonatal outcomes.

MRI interpretation of pediatric bone marrow is a challenging task due to the highly variable appearance. The bone marrow composition, especially the cellularity, changes with age, benign and malignant hematologic conditions, medications, among other etiologies. Detection of a marrow replacement process on MRI can be missed even by experienced radiologists. Normal hematopoietic bone marrow from birth to 9 years ranges from 20-40% fat (inversely related to cellularity). In malignant marrow replacement processes such as leukemia, bone marrow is highly cellular and fat percentage is low. Currently, no technique is routinely used in clinical practice to quantify bone marrow fat percentage on MRI. Read More
