There is a growing body of literature studying changes in hippocampal subfields in a variety of different neurological conditions, but this work has mainly focused on the hippocampal body given challenges in visualization of hippocampal anatomy in the head and tail when sectioned in the typical coronal image plane. Curved multiplanar reformatting (CMPR) is an image reconstruction method that can improve visualization of complex three-dimensional structures. The objective of this study was to determine whether CMPR could facilitate visualization of the human hippocampal anatomy along the entire caudal-rostral axis. CMPR was applied to high-resolution magnetic resonance imaging acquired ex vivo on four cadaveric hippocampal specimens at 4.7 T (T2-weighted, 0.2 × 0.2 × 0.5 mm3 ). CMPR provided clear visualization of the classic "interlocking C" appearance of the dentate gyrus and cornu ammonis along the entire caudal-rostral axis including the head and tail, which otherwise show complex anatomy on the standard coronal slices. CMPR facilitated visualization of hippocampal anatomy providing the impetus to develop simplified approaches to delineate subfields along the entire hippocampus including the usually neglected head and tail.

弯曲的多平面重格式化可改善海马解剖结构的可视化。

越来越多的文献研究各种神经系统条件下海马亚域的变化，但是这项工作主要集中在海马体上，因为在典型的冠状图像平面上进行剖面时，头和尾部的海马解剖学可视化面临挑战。弯曲多平面重新格式化（CMPR）是一种图像重建方法，可以改善复杂三维结构的可视化。这项研究的目的是确定CMPR是否可以促进沿整个尾-尾轴的人类海马解剖结构的可视化。CMPR用于在4.7 T（T2加权，0.2×0.2×0.5 mm3）的四个尸体海马标本上进行离体采集的高分辨率磁共振成像。CMPR为经典的“
