犬医学影像,超声波,核磁共振,x射线,x射线照相


什么是兽医诊断成像?

兽医诊断成像包括x光片(x光), 超声波, 核磁共振和CT扫描, 所有这些都被用作诊断工具来收集你的狗的健康信息. 绝大多数的影像学检查是非侵入性的 完全无痛. 然而, some imaging may require sedation or even anesthesia because the dog must be kept still to allow for adequate images to be produced. 兽医 use these images to collect information on your dog to help them to make a medical and sometimes surgical plan.

什么时候需要兽医诊断成像?

在你 兽医已经给你的狗做了检查, 他或她可能想要开始收集更多的信息,以导致诊断,然后, 一个治疗计划. x射线通常是第一道成像线. x光检查可能会导致诊断结果,从而使他们能够继续制定计划. 然而, sometimes the next step may be 超声波 to get a more thorough or specific look at a particular area of the body.

例如, 如果你的狗呕吐和感觉不舒服, you veterinarian may take an xray to look for possible causes such as obstruction of intestines or an obvious foreign body. x光片可能显示一些肠梗阻的征象, 然而, 在进行手术之前, 在某些情况下,谨慎的做法是进行腹部超声检查. The 超声波 will give more detail of the questionable area and t在这里fore allow more confidence of the treatment plan to move forward with surgery. 偶尔, x-rays and 超声波 allow for a definitive diagnosis but other times they will simply add more information to help put the puzzle together for the best treatment plan for your dog.

The four types of Veterinary Diagnostic Imaging our veterinarians may utilize to assist in diagnosis of your dog's condition are:

  • x射线
  • 核磁共振成像
  • 超声波
  • CT扫描

以下提供了有关每一种类型的射线照片的更多信息.

狗x射线

狗x光已经在整个医学界使用了几十年. Dog x-rays are by far the most regularly used form of diagnostic imaging in the veterinary industry because they are cost effective (comparatively speaking), 并能准确诊断骨骼结构和组成的状态, 大量蛀牙, 还有很多外来物体的存在. 狗的x光是完全无痛的, 但有些狗可以从镇静中受益,以减少焦虑和压力.

狗的x光检查通常如下:

  • 狗被放在x光检查台上
  • A technician positions the x-ray machine so that the x-ray beam targets only the area of interest
  • Modern x-ray equipment allow for low levels of radiation and when used only occasionally are perfectly safe for your dog
  • 因为狗的x射线是静态图像, 这个过程通常比核磁共振这样的过程需要更少的时间

传统上,狗的x光片是用胶片拍摄的,而且在必要的时候仍然可以使用. 然而, our x-ray images are now digital which allows us to capture the images on a secure server that our veterinarians can access at any time, 也可以与专家分享, 如果有必要的话.

狗超声波

A dog 超声波 is the second most common type of diagnostic imaging tool veterinarians use to diagnose a dog's medical condition. 超声波利用声波实时检查和拍摄内部组织. 超声波可以让兽医实时看到狗的身体状况, allowing for easy viewing of organs from different angles that are not easily achieved through x-rays. The functioning of various organs and blood flow can be observed to determine if they are malfunctioning.

狗的超声波检查过程通常如下:

  • A dog 超声波 technician gently presses a small probe against the dog's body that emits digital sound waves
  • The sound waves are directed to various parts of the dog's abdominal area by manually shifting the probe's position
  • 声束通过不同的人体组织密度时,速度会发生变化, 导致回声
  • Our 超声波 equipment converts these echoes into electrical impulses that are then further transformed into a digital image that represents the appearance of the tissues
  • 这些图像可以由兽医实时查看, 以及储存在任何时候进一步审查

In modern scanning systems like the ones 声望动物医院 has available and uses on our canine patients, 声束每秒会扫过身体很多次. 这就产生了一个动态的, 实时图像随着狗的超声波设备在狗的身体上移动而变化. 靠谱的菠菜平台可以利用超声波的结果来确定是什么让你的狗生病了, 设计出最有效的治疗方案.

导致兽医使用超声波的常见症状包括:呕吐, 减肥, 肾脏损害或阻塞和心脏病.

狗核磁共振

磁共振成像, 或核磁共振, 诊断成像的最新形式是否同时应用于人类医学和兽医医学. 狗的核磁共振成像设备能产生很强的磁场, 这样就能得到狗身上任何部位的详细解剖图像. 不需要x光,而且狗的核磁共振被认为是非常安全的.

狗的核磁共振成像程序通常如下:

  • 狗 must be sedated for this procedure because they cannot be restrained by humans and must remain still during the procedure
  • 在这个过程中,一只狗被放置在一个管状的电磁室中
  • The dog's body is continuously pulsed with radio waves for a period of time, usually 10-20 minutes
  • The pulsing causes the dog's body tissues to emit radio frequency waves that can be detected by the MRI equipment. Many repetitions of these pulses and subsequent emissions are required in order to generate adequate digital feedback for the equipment to interpret
  • 然后,反馈被转换成可以在屏幕上显示的图像, 而且还可以存起来供将来学习

A dog MRI is not used as regularly as an x-ray or 超声波 because the equipment is very expensive, 非常大的, 并需要经过专门训练的技术人员来操作. 然而, 声望动物医院 offers referral for comprehensive dog MRI services because we believe that facilitating complete canine care means having all the tools and training necessary to do so.

狗的CT扫描

狗的CT扫描, 也被称为Ôcat scans', 计算机增强的狗x光检查程序最常用于评估身体的复杂部位吗, 比如头部, 胸部, 一些关节和各种内脏. CT扫描显示不同程度的组织密度,并产生比x射线更详细的图像. 与核磁共振的, 狗的CT扫描 do not use magnetic field waves so they cannot compare changes in fluid levels due to inflammation or bleeding. 因此, 狗的CT扫描 are used in situations w在这里 an MRI is considered unnecessary but a traditional x-ray is inconclusive or insufficient.

对狗进行CT扫描通常如下:

  • 狗 must be sedated for this procedure because they cannot be restrained by humans and must remain still during the procedure
  • 狗被放置在CT扫描仪内的机动床上, 一种从不同角度接收一系列x射线的机器*
  • 当一个系列或扫描完成后,床向前移动,然后进行另一个扫描
  • A computer uses these scans to create cross-sectional images of the body part under investigation, and then display the images on a monitor (An x-ray dye may be injected intravenously to make it easier to see abnormalities)
  • 通过顺序扫描整个身体区域, 一个器官或其他结构可以在没有侵入性穿透身体的情况下成像, 或者破坏邻近的结构

狗的CT扫描 are most often used by our veterinarians to detect structural changes deep within a dog's body, 包括:

  • 肿瘤
  • 深部脓肿或异物存在
  • 骨折

就像MRI设备一样, CT扫描设备非常昂贵, 规模很大,需要训练有素的技术人员来操作. 然而, 声望动物医院 offers referral for comprehensive dog CTservices because we believe that facilitating complete canine care means having all the tools and training necessary to do so.

犬放射学如何影响兽医推荐

犬x光片的目的是确定诊断, 或者无需进一步执行就能得到最终答案, 更有侵入性的检查或程序. 例如, an x-ray might show some soft tissue swelling in the knee but the addition of an MRI would reveal the specific tendon or ligament tear that is causing a dog to limp and allow for a more specific treatment plan, 诊断和预后.

Veterinary diagnostic imaging offers an array of incredibly useful tools within a veterinarian's toolkit. 有时诊断成像会话可能导致进一步诊断的需要. This is why it is important to understand that diagnostic imaging may lead to a progressive fact-finding mission that must occur in order to diagnose your dog's ailment.
