How does an MRI on a cat work? - briefly
An MRI on a cat uses a strong magnetic field and radio waves to create detailed images of its internal structures, requiring the animal to remain still, often under anesthesia.
How does an MRI on a cat work? - in detail
Magnetic Resonance Imaging (MRI) on a cat involves using a powerful magnetic field, radio waves, and a computer to create detailed images of the cat’s internal structures. The process begins by placing the cat under anesthesia to ensure it remains still during the procedure, as any movement can distort the images. The cat is then positioned on a specialized table that slides into the MRI machine, which is a large, cylindrical magnet. Once inside, the machine generates a strong magnetic field that aligns the hydrogen atoms in the cat’s body. Radio waves are then emitted, causing these atoms to emit signals detected by the machine’s receiver coils. These signals are processed by a computer to construct cross-sectional images of the cat’s organs, tissues, and bones. The entire procedure is non-invasive and does not involve ionizing radiation, making it a safe diagnostic tool for veterinarians. The resulting images provide high-resolution details, allowing for accurate diagnosis of conditions such as tumors, spinal cord injuries, or brain abnormalities. The duration of the scan varies depending on the area being examined but typically lasts between 30 minutes to an hour. After the procedure, the cat is monitored as it wakes from anesthesia to ensure a smooth recovery.
