1. Definitions of microvascular features :微血管特点的定义

扩张Dilation: presence of a group of microvessel s whose calibers are twice or more than twice the calibers of surrounding ref-erence microvessels .

管径的徒然变化Abrupt caliber alteration: presence of a group of microvessels whose calibers abr uptly become less than one half or more than double the or iginal size. Disruption of microvessels is included in this definition.

密集Denseness: presence of a group of microvessels whose gross area is twice or more than twice that of sur rounding reference microvessels.

异质性（ 不均匀形态）Heterogeneity in shape: presence of a group of microvessels whose shapes are unique and highly variable.

扭曲Tortuousness: presence of a group of microvessels which are unpredictably twisted or bent .

区域性Regionality: presence of a clear border that is recognizable by the presence of a group of microvessels which are distinct from surrounding reference microvessels.

2.Definitions of fine mucosal structural features :FMS 特点的定义

缺失Absence: partial or complete disappearance of fine mucosal structure (FMS) from a target lesion.

微小化Micrification (size reduction 破碎) : FMS in a target lesion is smaller than one half of surrounding reference FMS.

异质性Heterogeneity: FMS are heterogeneous in shape.

FMS 示例

We defined diagnostic criteria for superficial gastric neoplasia by ME-NBI. If there were disappearance of fine mucosa structure and microvascular irregularities showing dilation, abrupt caliber alteration, heterogeneity in shape, and tortousness, the lesion was diagnosed as neoplastic.

ME-NBI 定义表浅胃癌诊断标准：如果有细黏膜结构（FMS）的消失和微血管不规则表现:扩张、突然口径变更、异质性在形状、扭曲等病变,考虑为肿瘤。

PS：胃早癌的两大判断指标：一个是腺管结构(S)，一个是血管结构(V)，任何一个出现以上文中的异常表现再加分界线（DL）的出现均可拟诊早癌，而如果非要说S与V谁更重要，我认为是S，因为S是因，而V是果，一个原凶，一个是帮凶，都是坏人，必须要抓！
