An MRI is the best type of imaging for looking at tissue. Your physician may order an MRI on the damaged muscle to find or learn more about your injury. This type of muscle tear imaging can pinpoint the location of even the smallest muscle strains and determine whether a partial or complete strain has occurred.
Muscle MRI can detect abnormal muscle volume, abnormal muscle signal (fatty infiltration or edema), mass lesion, and abnormal anatomy.

Muscle MRI is an important technique for evaluating disease activity. MRI studies demonstrated a correlation between the amount of inflammatory infiltrates within muscle biopsies and the intensity of STIR hypersignal (25, 35, 51).
Changes to ligaments and tendons as a result of disease and injury can be demonstrated using both ultrasound and MRI.
The bottom line is that not all pain is able to be detected on an x-ray or MRI. That does not mean that there is nothing there that needs to be treated or diagnosed. In fact, it means that it is possibly a precursor to something going really wrong and then eventually needing surgery because it eventually winds up torn.
The MRI scan provides clear and detailed images of soft tissue. However, it can't 'visualise' bone very well, since bone tissue doesn't contain much water. That is why bone injury or disease is usually investigated with regular x-ray examinations rather than MRI scanning.
Simply put, a “false negative” MRI is an MRI exam that fails to reveal a problem that is most certainly there. It's far more common than most people think.

MRI for muscle and connective tissue damage
In some cases, doctors can make a diagnosis based on a physical exam and symptoms. However, if the injury is more severe, an MRI can reveal whether you have a torn ligament or muscle.
An MRI may be able help identify structural lesions that may be pressing against the nerve so the problem can be corrected before permanent nerve damage occurs. Nerve damage can usually be diagnosed based on a neurological examination and can be correlated by MRI scan findings.
An MRI is best used when your doctor suspects a specific problem—something other than the muscle strain that causes most low back pain. An MRI usually isn't done when simple muscle strain is suspected, because: An MRI will not show muscle strains or other problems with soft tissues.
MRI is an imaging method that is very sensitive in detecting inflammation and also bone erosions.
Imaging can identify peripheral nerve tumors, traumatic neuromas, lacerations, entrapments with nerve damage, inflammation, demyelinating features, and infections. Ultrasound and MRI are the most commonly used methods for visualizing peripheral nerves.
MR images allow the physician to see even very small tears and injuries to tendons, ligaments and muscles and some fractures that cannot be seen on x-rays and CT.
Muscle injuries can be caused by bruising, stretching or laceration. The current classification divides such injuries into mild, moderate and severe.
Symptoms of Torn Muscles
Expect pain and soreness, as well as spasms and swelling in the affected area. Depending on the severity of the strain, you may find it difficult to move the area, if at all. You may note swelling as well as bruising and discoloration accompanied by a “knotted up” feeling or stiffness.
CT scan – where a series of X-rays are taken to create a detailed image of the inside of your body, which will reveal any muscle damage.
During the physical exam, your doctor will check for swelling and points of tenderness. The location and intensity of your pain can help determine the extent and nature of the damage.
A myoglobin test measures the amount of myoglobin, a protein found in your skeletal muscles (the muscles attached to your tendons and bones) and heart muscles, in your blood or urine (pee). Healthcare providers may use a myoglobin blood test to detect muscle damage.
An MRI machine uses powerful magnets that can attract any metal in your body. If this happens, you could get hurt. It can also damage equipment that's implanted in your body -- a pacemaker or cochlear implant, for instance. Also, metal can reduce the quality of the MRI image.
“Magnetic resonance imaging (MRI) is commonly used for diagnosis and as a research tool, but its accuracy is questionable.” The difference between a patient history and an MRI is that the MRI can be interpreted subjectively, open to interpretation, and often be a “roadblock,” in helping the patient heal.
It usually takes 1 to 2 weeks for the results of an MRI scan to come through, unless they're needed urgently.
Can a subject wear deodorant for an MRI scan? It is recommended to refrain from wearing any powder, perfumes, deodorant and/or lotions on your underarms and chest area prior to the procedure. This is to prevent the possibility of localized burns because these items may have metal in them.
However, due to the use of the strong magnet, MRI cannot be performed on patients with: Implanted pacemakers. Intracranial aneurysm clips. Cochlear implants.
