    Study Notes

    MRI Applications in Physiotherapy

    • MRI is used in physiotherapy to assess thoracic spine and chest wall soft tissues, including intervertebral disc pathologies, spinal cord compression, and chest wall tumors.
    • MRI can evaluate pelvic floor disorders, such as pelvic organ prolapse.
    • MRI allows detailed imaging of abdominal organs, including the liver, kidneys, and pancreas.
    • MRI is used to assess the sacroiliac joints.

    CT Applications in Physiotherapy

    • CT is beneficial for evaluating abdominal organs and vasculature, including liver cirrhosis, renal stones, and abdominal aortic aneurysms.
    • CT can be used to assess the bony pelvis and hip joints, helping to diagnose fractures and femoroacetabular impingement.

    CT Advantages and Limitations

    • CT offers advantages such as rapid acquisition for urgent conditions, excellent bone and lung imaging, and less motion artifact compared to MRI.
    • CT's limitations include ionizing radiation exposure, limited soft tissue contrast compared to MRI, and potential complications from contrast agents.

    Comparison of Imaging Modalities

    • Ultrasonography: No radiation, good soft tissue contrast, limited bone imaging, real-time imaging, low cost, fast speed.
    • MRI: Ionizing radiation, excellent soft tissue contrast, good bone imaging, no real-time imaging, high cost, slow speed.
    • CT: Ionizing radiation, moderate soft tissue contrast, excellent bone imaging, no real-time imaging, moderate cost, fast speed.
