A CT scan is typically performed after radiographic contrast media (dye) has been placed with fluoroscopic guidance into a sac-like lining (the first- and hardest and outermost- layer of the spinal meninges, the spinal dura mater) surrounding the spinal cord and nerves. The material is typically water-soluble, which has largely replaced ...
Cisternography is a medical imaging technique to examine the flow of cerebrospinal fluid (CSF) in the brain, and spinal cord. [1] [2] The gold standard for diagnosis of a cranial cerebrospinal fluid leak is CT cisternography. [2] For the diagnosis of a spinal CSF leak radionuclide cisternography also known as radioisotope cisternography is used ...
A computed tomography scan (CT scan), formerly called computed axial tomography scan (CAT scan), is a medical imaging technique used to obtain detailed internal images of the body. [2] The personnel that perform CT scans are called radiographers or radiology technologists.
Bone scans are conducted to rule out possible fractures and infections, magnetic resonance imaging (MRI) is used to eliminate the possibility of the spinal cord or nerve abnormalities, and computed tomography scans (CT scans) are used to get a more detailed image of the bones, muscles, and organs of the lumbar region.
In conventional CT machines, an X-ray tube and detector are physically rotated behind a circular shroud (see the image above right). An alternative, short lived design, known as electron beam tomography (EBT), used electromagnetic deflection of an electron beam within a very large conical X-ray tube and a stationary array of detectors to achieve very high temporal resolution, for imaging of ...
A radiographic evaluation using an X-ray, CT scan, or MRI can determine if there is damage to the spinal column and where it is located. [10] X-rays are commonly available [ 89 ] and can detect instability or misalignment of the spinal column, but do not give very detailed images and can miss injuries to the spinal cord or displacement of ...
As with any test that screens for disease, the risks of full-body CT scans need to be weighed against the benefit of identifying a treatable disease at an early stage. [6] An alternative to a full-body CT scan may be Magnetic resonance imaging (MRI) scans. MRI scans are generally more expensive than CT but do not expose the patient to ionizing ...
Spinal cord injury without radiographic abnormality (SCIWORA) is symptoms of a spinal cord injury (SCI) with no evidence of injury to the spinal column on X-rays or CT scan. [4] [5] Symptoms may include numbness, weakness, abnormal reflexes, or loss of bladder or bowel control. [2] Neck or back pain is also common. [3] Symptoms may be brief or ...
