感谢现代科学,让我们对恶心有了新的理解。
利用CT 技术和磁共振成像(MRI)技术,丹麦Aarhus 大学的科学家Kasper Hansen 和Henrik Lauridsen 将蟒蛇消化的整个过程给我们展现了出来。
通过在扫描过程中选择合适的光照对比度,以及赋予不同器官不同的颜色,我们就能够不使用解剖或者植入摄像头等形势,安全的观察动物体内的变化。
这是缅甸蟒蛇消化1只老鼠的过程(一共耗时132个小时),拍摄时间分别是吃下老鼠后2小时、16、24、32、48、72、132小时。

New Imaging Technology Shows Animal Insides, Python Digesting a Rat
Science is inherently cool, but gross science is even better.Using a combination of computer tomography (CT) and magnetic resonanceimaging (MRI), scientists Kasper Hansen and Henrik Lauridsen of Aarhus University in Denmarkwere able to visualize the entire internal organ structures andvascular systems (aka "guts") of a Burmese Python digesting a rat.
By choosing the right settings for contrast and light intensity duringthe scanning process, the scientists were able to highlight specificorgans and make them appear in different colors. The non-invasive CT andMRI scans could let scientists look at animal anatomy without the needfor other invasive methods such as dissections.
We had the scientists send us some exclusive step-by-step images of the process. While some might call them gruesome,we remind you that knifing your way through frog guts during highschool anatomy wasn't exactly pretty either. Keep reading to see thegradual, 132-hour disappearance of one rat from the python stomach.
This is a Burmese Python scanned before ingesting a rat and then attwo, 16, 24, 32, 48, 72 and 132 hours after dinner. The succession ofimages reveals a gradual disappearance of the rat's body, accompanied byan overall expansion of the snake's intestine, shrinking of thegallbladder and a 25 percent increase in heart volume.
