Vertebral hemangiomas or haemangiomas (VHs) are a common vascular lesion found within the vertebral body of the thoracic and lumbar spine.These are predominantly benign lesions that are often found incidentally during radiology studies for other indications and can involve one or multiple vertebrae.
Magnetic resonance myelography (MR myelography or MRI myelography) is a noninvasive medical imaging technique that can provide anatomic information about the subarachnoid space. It is a type of MRI examination that uses a contrast medium and magnetic resonance imaging scanner to detect pathology of the spinal cord , including the location of a ...
MRI image shows spinal bleeding (myelomalacia). Myelomalacia is a pathological term referring to the softening of the spinal cord. [ 1 ] Possible causes of myelomalacia include cervical myelopathy , hemorrhagic infarction , or acute injury, such as that caused by intervertebral disc extrusion.
On X-ray, giant-cell tumors (GCTs) are lytic/lucent lesions that have an epiphyseal location and grow to the articular surface of the involved bone. [8] Radiologically the tumors may show characteristic 'soap bubble' appearance. [9] They are distinguishable from other bony tumors in that GCTs usually have a nonsclerotic and sharply defined border.
MRI provides better resolution of tissue density, absence of bone interference, multiplanar capabilities, and is noninvasive. Plain films may show bony erosion of the spinal canal or of the sacral foramina. [citation needed] On MRI pictures, the signal is the same as the CSF one. If MRI made with a contrast medium: [citation needed]
Modic changes are observed on MRI (magnetic resonance imaging) scans. Bone oedema in other bones is not categorized into different types, but Dr. Michael Modic was the first to classify, describe and define Modic changes into three types. The different types were first described and defined in 1988. [39]
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 Today, myelography has largely been replaced by the use of MRI scans , although the technique is still sometimes used under certain circumstances – though now usually in conjunction with CT ...
Finally, the use of magnetic resonance imaging (MRI) allowed for even better depiction of the spine and soft tissue abnormalities in particular. Again, a novel acronym was proposed to classify patients without traumatic signs using radiographs, CT and MRI. The term spinal cord injury without neuroimaging abnormality (SCIWONA) was used.
