studies

X-rays are usually the first imaging studies that are performed to evaluate pain.  X-rays are great at evaluating the bone structures, but do very little in providing information about soft tissues, such as a disc, nerve, or muscle.  In the setting of trauma, x-rays are utilized to assess if there is a broken bone or if there is a dislocation.  In regards to the spine, it can provide information about its curvature, alignment, spacing between the bones, and arthritic changes.  It cannot detect if there is a herniated disc or a muscle strain.

MRIs can evaluate structures in further detail than x-rays, especially soft tissues.  When ordered for the neck or low back, it can assess if there is a herniated disc or other causes of a pinched nerve.  

One of the first questions that Dr. Garala is asked in the office by patients is if he can order a MRI to diagnosis the source of pain.  There is a misconception that MRIs can do this and are the SOLE determinant in providing a diagnosis (please read MRI Misconception under the Education Section).  MRIs are anatomical studies, which can provide SUPPORTING evidence of a clinical diagnosis.  

MRIs do not necessarily need to be ordered upon the first visit, especially if the pain just began, is not leading to any neurological deficits (i.e. muscle weakness or sensation changes) or won’t change the initial treatment.  Whether an MRI is ordered or not, the initial treatment plan will likely be the same, including medications and physical therapy.  If pain symptoms do not improve over time with these conservative treatments, an MRI may then be needed to then determine if the patient could benefit for a spinal injection, for which an MRI would be needed for planning purposes (to help establish the possible level of the pinched nerve and the safest route to the deliver the medication).

Please also keep in mind that since MRIs are considered advanced studies, they need prior insurance approval (they usually cannot be done immediately such as when x-rays are ordered).  Insurance companies usually have a list of guidelines that need to be met (medications, failed conservative physical therapy for six weeks) before they typically approve of getting an MRI.  

If you have any questions about getting an MRI, please let Dr. Garala’s team know.

CT scans are great imaging studies to evaluate bones.  They provide finer details than x-rays for bone structures to help assess the extent of a fracture.  However, they are not as good as MRIs at evaluating soft tissues such as herniated discs or pinched nerves.  They may be used as a substitute for MRIs if there is a contraindication for the MRI such as the patient having a defibrillator (having metal on/in a person is a typical contraindication because MRIs use strong magnets).

Nerve Conduction Studies/Electromyography (NCS/EMG) are considered an extension of the physical exam.  They are electrical studies of nerves and muscles, and are performed by a specialist because of the technical demands of the study.  Their results can help establish an electrodiagnosis of a nerve or muscle injury, such as a pinched nerve coming from the neck or back, or a condition such as carpal tunnel syndrome.
