摘要目的探讨和校正对尸体标本胸腹部器官软组织鉴定和鉴别的MR定量分析的温度依赖性。材料与方法应用定量序列对35例尸体标本进行心脏短轴位3 T MRI检查。用心脏短轴位影像对肝、脾、左心室肌、胸大肌和皮下脂肪进行分析来获得平均T1、T2和质子密度(PD)组织值。采用直肠插入温度计测量核心体温。组织特异性定量值与核心体 Abstract Objective To investigate and correct the temperature dependence of MR quantitative analysis on the identification and identification of soft tissue in the thoracic and abdominal organs of cadaver specimens. Materials and Methods Three short-axis 3 T MRI images of 35 corpse specimens were obtained by quantitative sequence analysis. Mean T1, T2 and proton density (PD) tissue values ​​were obtained from the short axis images of the heart, liver, spleen, left ventricular muscle, pectoralis major muscle and subcutaneous fat. Core temperature was measured using a rectal thermometer. Tissue-specific quantification and core body
