Historically the procedure involved the injection of a radiocontrast agent into the cervical or lumbar spine, followed by several X-ray projections. Today, myelography has largely been replaced by the use of MRI scans , although the technique is still sometimes used under certain circumstances – though now usually in conjunction with CT ...
Quantitative computed tomography (QCT) is a medical technique that measures bone mineral density (BMD) using a standard X-ray computed tomography (CT) scanner with a calibration standard to convert Hounsfield units (HU) of the CT image to bone mineral density values. [1]
Bertolotti's syndrome is characterized by sacralization of the lowest lumbar vertebral body and lumbarization of the uppermost sacral segment. It involves a total or partial unilateral or bilateral fusion of the transverse process of the lowest lumbar vertebra to the sacrum, leading to the formation of a transitional 5th lumbar vertebra.
Anterior view X-ray of a spinal cord stimulator (SCS) implanted in the thoracic spine [ edit on Wikidata ] A spinal cord stimulator ( SCS ) or dorsal column stimulator ( DCS ) is a type of implantable neuromodulation device (sometimes called a "pain pacemaker") that is used to send electrical signals to select areas of the spinal cord (dorsal ...
An X-ray of the spinal canal following injection of a contrast material into the surrounding cerebrospinal fluid spaces will reveal displacement of the contrast material. It can show the presence of structures that can cause pressure on the spinal cord or nerves, such as herniated discs, tumors, or bone spurs. Because myelography involves the ...
On plain X-ray, a Chance fracture may be suspected if two spinous processes are excessively far apart. [10] A CT scan of the chest, abdomen, and pelvis is recommended as part of the diagnostic work-up to detect any potential abdominal injuries. [5] [10] MRI may also be useful. [10] The fracture is often unstable. [1]
A 2021 study of more than 66,000 elective lumbar spine fusion surgeries for spondylolisthesis found the average hospital costs for the procedure were $30,827 in 2019, or $37,638 when adjusted for ...
Retrolistheses are most easily diagnosed on lateral x-ray views of the spine. Views, where care has been taken to expose for a true lateral view without any rotation, offer the best diagnostic quality. Retrolistheses are found most prominently in the cervical and lumbar region, but can also be seen in the thoracic area.
