MRI能够发现青少年体内隐藏的脂肪

 
根据一项最新研究发现，单层核磁共振扫描(MRI)是一种快速非侵入性鉴别腹腔内脂肪的方法，腹腔内脂肪过度沉积会导致儿童和青少年患心脏病、糖尿病和其它疾病的危险增高。

当前使用的测定身体脂肪的方法包括人体测量学，使用物理测量方法诸如腰围，腹部长度，体重指数，二重能量吸收测量(DEXA)，这是一种全身扫描，能够区分机体非脂肪组织和脂肪组织。但是人体测量学并不精确，而DEXA需要暴露于例子辐射之中。

MRI Reveals Hidden Fat in Adolescents
 
According to a new study, single-slice magnetic resonance imaging (MRI) is a fast, non-invasive way to identify intra-abdominal fat, which when excessive, may place children and teenagers at risk for developing heart disease, diabetes, and other disorders.

Current methods used to estimate body fat include anthropometry, which involves physical measurements including waist circumference, abdominal height, and body mass index, and dual energy absorptiometry (DEXA), a whole-body scan that differentiates lean mass from fat tissue. However, anthropometry is inexact and DEXA requires exposure to ionizing radiation.
