Diagnostic Imaging Services

Understand and analyze your health

We offer a comprehensive range of diagnostic imaging services specifically tailored to patients who have been involved in motor vehicle accidents. These services include:

  1. MRI (Magnetic Resonance Imaging): We utilize advanced MRI technology to obtain detailed and high-resolution images of various body parts. This imaging technique is particularly useful in identifying and diagnosing injuries sustained in motor vehicle accidents.

  2. Brain SPECT Scan: Specialized Brain SPECT (Single-Photon Emission Computed Tomography) scan provides valuable insights into the functioning and blood flow within the brain. It aids in the evaluation and diagnosis of potential brain injuries or abnormalities resulting from the accident.

  3. EMG (Electromyography): EMG is a diagnostic procedure used to assess the health of muscles and the nerve cells that control them. It can help identify nerve damage, muscle dysfunction, and other related issues that may have occurred as a result of the motor vehicle accident.

  4. Sleep Study: We also offer sleep studies to evaluate sleep disorders and their potential impact on patients who have been involved in motor vehicle accidents. This assessment helps identify and address any sleep-related issues that may be affecting recovery and overall well-being.

Our dedicated team of medical professionals utilizes these diagnostic imaging services to provide accurate and comprehensive assessments, enabling appropriate treatment and care for patients recovering from motor vehicle accidents.
