| == Computerised Axial Tomography (CT Scan) ==
| |
| | |
| '''''Computed Tomography (CT)''''' is an imaging technique that takes multiple x-rays from different angles and creates cross-sectional images of a body part. Cross-sectional slices are typically 1-3 mm thick, depending upon the type and location of the tissue. CT scans are primarily used for bony pathologies, but can also be used for soft tissue dysfunction. CT scans are not as effective at detecting soft tissue pathology as MRIs because there is not enough differentiation in the x-ray absorption of injured and healthy tissue. Other benefits of CT scans are that they are fast, relatively inexpensive and often a good alternative to MRIs if an MRI is contraindicated.<ref name="Swain">Swain J, Bush K.

| == Bone Scan ==
| |
| | |
| '''''Bone scan''''' is an imaging technique that uses a radioactive compound to identify areas of healing within the bone. Bone scans work by drawing blood from the patient and tagging it with a bone seeking radiopharmaceutical. This radioactive compound emits gamma radiation. The blood is then returned to the patient intravenously. As the body begins its metabolic activity at the site of the injury, the blood tagged by the radioactive compound is absorbed at the bone and the gamma radiation at the site of the injury can be detected with an external gamma camera. A bone scan can be beneficial in determining injury to the bone within the first 24-48 hours of injury or when the displacement is too small to be detected by an x-ray or CT scan.<ref name="Swain" />
