One hundred sixteen magnetic resonance (MR) imaging studies from 105 pediatric patients with a variety of cerebral abnormalities were reviewed to determine the diagnostic efficacy of MR in the pediatric population. All subjects tolerated the MR procedure well, although sedation was necessary for younger children. Compared with CT, MR proved to be advantageous in detection and characterization of the pathology in 23 of 105 patients, especially when the abnormality was located along the base of the brain and midline, or when it involved primarily the white matter. Intracranial calcification was the one abnormality not detected with MR although dense calcifications could be seen as areas of low signal intensity. Some characteristics of various pathological entities were compared in an attempt to differentiate among abnormalities in the same anatomical location: craniopharyngioma from optic chiasm and hypothalamic glioma, cystic glioma from arachnoid cyst, and chronic subdural hematoma from subdural hygroma. The lack of ionizing radiation in MR is of particular interest in pediatric neuroradiology since radiation is of special concern in the young age group.
回顾了105例患有各种脑部异常的儿科患者的116份磁共振（MR）成像研究，以确定MR在儿科人群中的诊断效能。所有受试者对MR检查耐受良好，不过年幼儿童需要镇静。与CT相比，在105例患者中的23例中，MR在病变的检测和特征描述方面被证明具有优势，尤其是当异常位于脑底部和中线，或主要累及白质时。颅内钙化是MR未检测到的一种异常，尽管致密钙化可表现为低信号强度区域。比较了各种病理实体的一些特征，试图区分同一解剖部位的异常：颅咽管瘤与视交叉和下丘脑胶质瘤、囊性胶质瘤与蛛网膜囊肿、慢性硬膜下血肿与硬膜下积液。MR不存在电离辐射这一点在儿科神经放射学中尤为重要，因为辐射在儿童年龄组中是特别需要关注的问题。
