Magnetic resonance imaging may be useful if it is necessary to exclude a ligament injury. [8] The indication for MR spine is a focal neurological deficit. Another indication for MR of the cervical spine is persistent mid-line neck pain or tenderness despite a normal CT in the awake patient.
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 ...
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.
There are two main algorithms, the Canadian C-spine rule and NEXUS, which are used to decide who requires cervical spine imaging via CT scan [6] after blunt trauma, and who can be cleared without imaging. [4] The Canadian C-spine rule appears to have greater sensitivity and specificity (i.e. fewer false positives and false negatives). [17]
Cervical spinal nerve C7 controls triceps and wrist extension. Cervical spinal nerve C8 helps control the hand. [18] The cervicocranial syndrome occurs when symptoms arise due to cervical vertebrae damage (misalignment, collapse, shift or disease, such as tumor) resulting in the improper functioning of the cervical spinal nerves.
Blood work might be utilized in addition to radiographic imaging in order to identify spinal cord diseases. Basic imaging techniques, which includes x-ray imaging, can reveal degenerative changes of the spine, while more advanced imaging techniques, such as computed tomography (CT) and magnetic resonance imaging (MRI), can allow visualization ...
A computed tomography (CT) scan is another examination method often used for the diagnosis of Tarlov cyst. Unenhanced CT scans may show sacral erosion, asymmetric epidural fat distribution, and cystic masses that have the same density with CSF. [7] CT Myelogram is minimally invasive, [27] and could be employed when MRI cannot be performed on ...
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 ...
