There are several types of injuries that may not be picked up by an MRI or CT scan. These types of imaging tests are highly sensitive and can detect many types of injuries, but they are not always able to detect all types of injuries.
Some examples of injuries that may not be picked up by an MRI or CT scan include:
- Mild traumatic brain injuries: Mild traumatic brain injuries, also known as concussions, may not be detectable using imaging tests like an MRI or CT scan. Instead, these injuries are typically diagnosed based on symptoms, such as headache, dizziness, and difficulty concentrating.
- Soft tissue injuries: Soft tissue injuries, such as sprains, strains, and contusions, may not be visible on an MRI or CT scan. These injuries can often be diagnosed based on physical examination and symptoms, such as swelling and tenderness.
- Psychological injuries: Psychological injuries, such as depression, anxiety, and post-traumatic stress disorder, are not detectable using imaging tests like an MRI or CT scan. These injuries are typically diagnosed based on symptoms and a mental health evaluation.
- Chronic pain: Chronic pain, which is pain that lasts for three months or longer, may not be detectable using imaging tests like an MRI or CT scan, depending on the underlying cause of the pain. Chronic pain is often diagnosed based on a person's symptoms and a physical examination.
