Magnetic resonance images of the cranial abdomen were acquired from 15 clinically normal cats. All cats had T1-weighted images, 8 cats had T2-images made and 7 cats had T1-weighted post Gd-DTPA images acquired. Signal intensity measurements for T1, T2, and T1 post contrast sequences were calculated for liver, spleen, gallbladder, renal cortex, renal medulla, pancreas, epaxial muscles, and peritoneal fat. On T1-weighted images the epaxial muscle had the lowest signal intensity, followed by renal medulla, spleen, renal cortex, pancreas, liver and fat, respectively. On T2-weighted images, epaxial muscle had the lowest signal intensity followed by liver, spleen, fat, and gallbladder lumen. Calculations of specific organ percent enhancement following contrast medium administration were made and compared with that reported in humans. A brief review of the potential clinical uses of MR in cats is presented.
对15只临床健康的猫进行了颅腹部磁共振成像检查。所有猫均有T1加权图像，8只猫进行了T2加权图像检查，7只猫进行了钆喷酸葡胺（Gd-DTPA）增强后的T1加权图像检查。计算了肝脏、脾脏、胆囊、肾皮质、肾髓质、胰腺、轴旁肌肉和腹膜脂肪在T1、T2及T1增强序列上的信号强度测量值。在T1加权图像上，轴旁肌肉的信号强度最低，其次分别是肾髓质、脾脏、肾皮质、胰腺、肝脏和脂肪。在T2加权图像上，轴旁肌肉的信号强度最低，其次是肝脏、脾脏、脂肪和胆囊腔。计算了造影剂注入后特定器官的增强百分比，并与人类的相关报道进行了比较。本文还简要回顾了磁共振成像在猫中的潜在临床应用。
