Abstract

Magnetic resonance image quality in infants and children has been improved by the use of spherical receiver coils and age-adjusted sequences allowing use of a high-resolution (256 X 256) image reconstruction matrix, provided adequate immobilisation is maintained. This increased resolution provides more satisfactory demonstration of the cortical mantle and details of sulci, as well as pathological processes such as periventricular oedema, infarction and tumours.

摘要

通过使用球形接收线圈和根据年龄调整的序列，婴儿和儿童的磁共振图像质量得到了改善。只要能保持足够的固定，这些技术允许使用高分辨率（256×256）的图像重建矩阵。这种更高的分辨率能更令人满意地显示皮质层和脑沟细节，以及诸如脑室周围水肿、梗死和肿瘤等病理过程。
