A Computed Tomography, or CT scan, is an imaging test that combines computers and 360-degree x-rays to produce highly detailed images of the body. It's painless, fast, non-invasive, and extremely accurate. Common areas of scanning include the chest, abdomen, and pelvis area. The CT scan is a vital tool in diagnosing disease, planning treatment for surgical, medical, and radiation treatment. A CT scan can depict bone, blood vessels, and soft tissue inside the body. This is significant in identification and proper diagnosis of infection, blood clot, internal bleeding, or disease.
Magnetic Resonance Imaging provides highly detailed pictures of anatomy and pathology to help evaluate a wide range of conditions in the body. MRI uses a strong magnetic field and radiofrequency pulses to produce clear and detailed pictures. The machine uses an intense magnetic field and radio waves to create images of parts of the body that can’t be seen well via X-Ray or CT Scan. The technology produces three-dimensional (3D) anatomical images. The device and technique allow for viewing inside the muscle, joints, ligaments, tendons, cartilage, and internal organs.
Myelography uses a real-time form of x-ray called fluoroscopy and an injection of contrast material to evaluate the spinal cord, nerve roots and spinal lining. By injecting contrast material into the spine, doctors can visualize the spinal cord, nerves, and tissues that line the nerves (meninges). Myelography is typically used to evaluate the spine before and after surgery and to detect problems in patients who cannot undergo MRI.
MR arthrography (arthrogram) is a contrast-enhanced study used to visualize the interior of joints in a very detailed way. An arthrogram helps doctors diagnose problems with the bones, cartilage, ligaments, and tendons within a joint. Arthrograms are especially useful for determining the cause of unexplained joint pain. Contrast material (gadolinium based) is injected directly into the joint which distends or enlarges the joint thus allowing for enhanced visualization of small internal structures. This leads to improved evaluation of diseases or conditions within the joint. Joint injections are done immediately before the MRI exam using fluoroscopic guidance.
