Article Synopsis
- - The study investigates the risk of subdural hemorrhages (SDHs) in extremely premature infants, focusing on their prevalence, identification agreement in MRI evaluations, and measuring subarachnoid spaces.
- - A total of 121 infants underwent MRI, revealing no significant SDHs, but 49.5% had some form of intracranial hemorrhage related to prematurity, with reliable identification rates for hemorrhage across observers.
- - The findings suggest that premature infants are not more susceptible to SDHs not caused by abuse in the first few months, though many exhibited enlarged subarachnoid spaces.
Article Synopsis
- - The study aimed to compare two MRI sequences—T2 Dixon fat-only and T1-weighted—in assessing high signal areas in bone marrow of healthy children and adolescents, focusing on optimizing scan time.
- - Data from 196 participants aged 6 to 19 years were analyzed, and a scoring system classified findings as "minor" or "major," with high agreement (94.6%) between sequences for the majority of assessed areas.
- - The findings suggest that T2 Dixon fat-only can effectively replace T1-weighted sequences for kids over nine, leading to reduced MRI scan durations.
Objectives: To compare short time inversion recovery (STIR) and T2 Dixon in the detection and grading of high signal intensity areas in bone marrow on whole-body MRI in healthy children.
Methods: Prospective study, including whole-body 1.5-T MRIs from 77 healthy children.
Background: Hip involvement predicts severe disease in juvenile idiopathic arthritis (JIA) and is accurately assessed by MRI. However, a child-specific hip MRI scoring system has not been validated.
Objective: To test the intra- and interobserver agreement of several MRI markers for active and chronic hip changes in children and young adults with JIA and to examine the precision of measurements commonly used for the assessment of growth abnormalities.
Article Synopsis
- The study investigates high signal areas on T2 weighted MRI images of the bone marrow in the axial skeleton of healthy children and adolescents aged 5-19 years.
- A total of 196 participants were examined, leading to the identification of 415 areas of increased signal, with 75 categorized as major findings, particularly in the pelvis.
- The findings highlighted the prevalence of non-specific bone marrow hyperintensities, emphasizing the need for awareness to differentiate these from actual skeletal diseases in children.
