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.
