A properly functioning MRI coil is essential for producing high-quality diagnostic images. When a coil begins to fail, it can lead to frustrating artifacts, signal loss, and, eventually, a full system shutdown. Knowing the early warning signs can help you prevent costly downtime and get your equipment repaired before it becomes a bigger problem.
Here are five common signs that your MRI coil may be in need of repair:
- Image Artifacts: One of the most common indicators is the appearance of unexpected artifacts on your images. These can include anything from “salt and pepper” noise and ghosting to black lines or blotches. These artifacts often indicate a problem with the coil’s electronics or a damaged component within the coil itself.
- Cable or Connector Damage: Visually inspect the coil’s cables and connectors. Look for frayed wiring, cracks in the housing, or bent connector pins. Even minor damage can disrupt signal transmission and compromise image quality.
- Signal Loss or Fading: If you notice a general decrease in signal intensity, especially in specific areas of the image, it could be a sign of a failing element within the coil.
- Heating or Odor: Any unusual heat or a burning smell coming from the coil during operation is a critical red flag. This can indicate a serious electrical short and requires immediate shutdown and repair to prevent further damage.
- Failure to be Recognized: The most definitive sign of failure is when the MRI system simply fails to recognize or connect to the coil. This usually points to a significant issue with the coil’s internal electronics or a broken communication component.
If you observe any of these signs, don’t wait for a complete failure. Taking action early can save you time and money. At MIT Labs LLC, we specialize in component-level MRI coil repair, restoring your equipment to a high-quality, working condition.
