MRI Scans– Magnetic Resonance Imaging
Specific types of imaging; CT, ultrasound, MRI are used for specific body areas or suspected disease conditions. In having access to all these modalities increases our ability to quickly diagnose and start treatment.
How does an MRI machine work?
A powerful magnet within the MRI machine aligns the protons in the hydrogen of water molecules of the body in the same direction as the magnetic field. The computer then delivers a brief radiofrequency (RF) pulse that knocks the protons out of alignment. After the RF pulse ends, the protons return to alignment with the magnet, giving off energy that is detected by a receiver (“coil”) placed on or around the patient. This signal is then processed by a computer to provide a detailed image of the body.
MRI scans in veterinary medicine are most often used to image the central nervous system (brain and spinal cord) as well as other body areas usually soft tissue structures, muscle etc.
Your pet will need an anaesthetic or strong sedation as they need to remain still for the examination. This will be discussed with you before the procedure starts.
A specialist radiologist’s report is required for most MRI scans so the results will not be immediately available.
Pretoria Pet MRI situated at Valley Farm Animal Hospital performs all of our patients MRI scans, this means your pet never has to leave our premises and can be cared for by our staff throughout if necessary.
