It is quick, inexpensive and usually does not require anesthesia. CT (computed tomography) : X-rays are also used here, but from different angles.
A computer processes this information into detailed cross-sectional images. CT is particularly useful for examining complex structures such as the brain, spine and internal organs. It provides three-dimensional images and usually requires a short period of anesthesia. MRI (Magnetic Resonance Imaging) : MRI uses strong magnetic fields and radio waves to create high-resolution images of soft tissues, nerves and organs. Unlike X-rays and CT, MRI does not use ionizing radiation. It is particularly suitable for examining the brain, joints and soft tissue tumors and also requires anesthesia.
When should a veterinarian use X-ray instead of CT or MRI?
A veterinarian usually chooses x-rays when:
Broken bones or joint problems are suspected: X-rays are very effective for visualizing bones and joints.
It enables rapid and cost-effective diagnosis of fractures, dislocations and arthritic changes. a suspicion of a tumor : X-rays can help detect bone tumors or tumors in the lungs.
Foreign bodies are suspected in the animal's body : X-rays are good for locating metal or bone fragments that have been swallowed or inhaled.
Routine Examinations : During regular checkups, especially for older animals or breeds prone to certain orthopedic problems, x-rays are a quick and straightforward way to assess the general condition of bones and joints.
What preparation is necessary for a CT or MRI examination on an animal?
For CT and MRI examinations, some preparations are necessary to ensure the safety of the animal and to obtain optimal images:
Fasting : The animal should generally not eat anything for a few hours before the examination.
This is important to minimize the risk of complications during anesthesia. Anesthesia : Since both CT and MRI require the animal to be completely still, anesthesia or strong sedation will be necessary in most cases.
The veterinarian will select the anesthetic based on the animal's health, age and size. Medical History : Tell the veterinarian about any existing health problems, allergies, or medications your pet is taking.
This helps select the safest anesthesia and imaging methods. Reassurance : It may be helpful to calm the animal before the exam and bring a familiar blanket or toy to minimize stress.
