                    <p>从伦琴发现X线到CT出现使我们能够清晰的看到身体内部的解剖结构，大大方便了疾病的诊断，提高了疾病诊断的准确性，被誉为放射医学的里程碑，而螺旋CT和多层螺旋CT的出现使得CT的检查更加方便、快捷，应用更加广泛，成为放射医学的又一个里程碑。16排螺旋CT的出现使CT的发展达到前所未有的境界，它的快速、薄层、大面积扫描不仅使CT真正意义上可以对人体任何器官和部位进行有效的检查，而且对我们以往的传统医学诊断观念和方法带来了全新的变革，使得诊断更加容易、更加安全、更加准确。</p><p><br  /></p><p>实 例 介 绍</p><p><br  /></p><p>16排螺旋CT大血管成像</p><p><br  /></p><p>16排螺旋CT通过快速、薄层、大面积扫描成像，对大血管能够非常清楚的显示和评价，对于大血管的病变、走行异常都能非常清楚的显示，无创的检查方法也使患者更容易耐受检查。</p><p><br  /></p><p>16排螺旋CT肺结节定量成像</p><p><br  /></p><p>肺癌是呼吸系统最常见的恶性肿瘤，对于肺内的结节病灶有一部分可能是肺癌的早期表现，而对于小于2cm的结节往往不能够定性，以往通过肉眼来判断某个时间段内的体积、形态变化，这种判断敏感性很低，16排螺旋CT肺结节定量成像，可以准确的评估肺结节的体积、形态以及时间段内的倍增时间，为肺内结节的良恶性判别提供最客观的依据。</p><p><br  /></p><p>16排螺旋CT脑灌注成像检查</p><p><br  /></p><p>脑梗塞是常见多发病，早期诊断非常重要但是一直很困难，16排螺旋CT灌注成像通过对缺血脑组织的微循环进行评价，可以在早期发现脑梗塞，从而为及时的溶栓治疗提供依据，大大减少脑梗塞的并发症和后遗症。</p><p></p><p>16排螺旋CT胃肠道成像</p><p> </p><p>多排螺旋CT的产生，使得胃肠道成像成为可能，16排螺旋CT使CT对空腔脏器的检查更加快捷、易接受和准确，通过后处理工作站进行三维和仿真内窥镜检查可以代替传统的钡餐以及胃镜的诊断功能。胃肠道的平铺功能可以将胃肠道官腔平铺成一个平面，更加便于观察和诊断，提高了诊断的准确性。</p><p></p><p>16排螺旋CT在心脏冠脉的影像检查</p><p> </p><p>冠心病日益成为危害人类健康的杀手，被认为是冠心病诊断金标准的冠脉造影检查需要在血管内放入导管、导丝，具有一定的危险性。16排螺旋CT利用其亚秒的扫描速度可以进行无创性心脏冠脉成像，使得冠心病的诊断变为几近零风险；另外16排螺旋CT成像可以看到常规心导管造影看不到的粥样斑块、动脉肌桥，而且能够区分软硬斑块，从而对治疗方案起到决定性的作用。</p><p></p><p>16排螺旋CT肿瘤灌注成像检查</p><p> </p><p>恶性肿瘤的诊断和早期诊断一直是困扰临床医学的难题，16排螺旋CT肿瘤灌注成像通过对肿瘤微循环血流动力学变化进行评估可以在早期进行肿瘤的诊断，同时可以对良恶性肿瘤进行鉴别，评价治疗后的效果及复发情况，从而可以及时有效的早期治疗和评价预后。</p><p style=""><img src="http://mmbiz.qpic.cn/mmbiz/rz7R73cuHRrv6jdOCoJeZmYwvEAIoHpY0a7yJL2egiaEokLTpwkIsIRTzTFUic09aEThKHS4hrEcSqU0lAS3tu5g/0" data-ratio="0.14784394250513347" data-w="487" width="auto" width="auto" src="http://mmbiz.qpic.cn/mmbiz/rz7R73cuHRrv6jdOCoJeZmYwvEAIoHpY0a7yJL2egiaEokLTpwkIsIRTzTFUic09aEThKHS4hrEcSqU0lAS3tu5g/0?tp=webp" style="margin: 0px;
