ConeBeam computerized tomography image of a post-operative orthognathic surgery. Oral and maxillofacial radiology, also known as dental and maxillofacial radiology, or even more common DentoMaxilloFacial Radiology, is the specialty of dentistry concerned with performance and interpretation of diagnostic imaging used for examining the craniofacial, dental and adjacent structures.
MRI imaging appears to be the gold standard for diagnosing a tethered cord. [16] [17] A tethered cord is often diagnosed as a "low conus". The conus medullaris (or lower termination of the spinal cord) normally terminates at or above the L1-2 disk space (where L1 is the first, or topmost lumbar vertebra). After about 3 months of age, a conus ...
The filum terminale is situated centrally [2] amid the spinal nerve roots of the cauda equina [3] [2] (but is not itself a part of the cauda equina [2]).. The inferior-most spinal nerve, the coccygeal nerve, leaves the spinal cord at the level of the conus medullaris via respective vertebrae through their intervertebral foramina, superior to the filum terminale.
Diastematomyelia is a "dysraphic state" of unknown embryonic origin, but is probably initiated by an accessory neurenteric canal (an additional embryonic spinal canal.).) This condition may be an isolated phenomenon or may be associated with other segmental anomalies of the vertebral bodies such as spina bifida, kyphoscoliosis, butterfly vertebra, hemivertebra and block vertebrae which are ...
Myelography is a type of radiographic examination that uses a contrast medium (e.g. iodised oil [1]) to detect pathology of the spinal cord, including the location of a spinal cord injury, cysts, and tumors. Historically the procedure involved the injection of a radiocontrast agent into the cervical or lumbar spine, followed by several X-ray ...
Lipiodol is also used in lymphangiography, the imaging of the lymphatic system. [10] Historically Lipiodol was often used as a contrast medium at hysterosalpingography (HSG: a procedure to determine tubal patency [i.e. whether the fallopian tubes are open], used in the investigation of subfertility). It became less commonly utilized in the ...
Iohexol, sold under the trade name Omnipaque among others, is a contrast agent used for X-ray imaging. [4] This includes when visualizing arteries, veins, ventricles of the brain, the urinary system, and joints, as well as during computed tomography (CT scan). [4] It is given by mouth, injection into a vein, or into a body cavity. [5]
A panoramic radiograph is a panoramic scanning dental X-ray of the upper and lower jaw.It shows a two-dimensional view of a half-circle from ear to ear. Panoramic radiography is a form of focal plane tomography; thus, images of multiple planes are taken to make up the composite panoramic image, where the maxilla and mandible are in the focal trough and the structures that are superficial and ...
