However, MRI is preferred since scintigraphy lacks specificity. In case of isolated bone marrow edema in MRI without a fracture line, the diagnosis of fatigue fracture may be more complicated, and other conditions such as transient edema and osteoid osteoma need to be excluded. Additional imaging by CT is warranted in such cases. [1]
A compression fracture is a collapse of a vertebra. It may be due to trauma or due to a weakening of the vertebra (compare with burst fracture ). This weakening is seen in patients with osteoporosis or osteogenesis imperfecta , lytic lesions from metastatic or primary tumors , [ 1 ] or infection. [ 2 ]
MRI-scans are becoming more valuable in the analysis of articular cartilage but their use is still expensive and time-consuming. X-rays show only bone injuries and are therefore not very helpful in diagnosing cartilage damage, especially not in early stages. The best tool for diagnosing articular damage is the use of arthroscopy. [citation needed]
Compression fracture/wedge fracture: Usually occurs in the vertebrae, for example when the front portion of a vertebra in the spine collapses due to osteoporosis (a medical condition which causes bones to become brittle and susceptible to fracture, with or without trauma) Impacted fracture Bone fragments are driven into each other more images
Degenerative disc diseases have shown a correlation with Modic type 1 changes. When evaluating for postoperative lumbar radiculopathies, the recommendation is that the MRI is performed with contrast unless otherwise contraindicated. MRI is more effective than CT in distinguishing inflammatory, malignant, or inflammatory etiologies of LDH.
A flexion teardrop fracture is a fracture of the anteroinferior aspect of a cervical vertebral body due to flexion of the spine along with vertical axial compression. [1] The fracture continues sagittally through the vertebral body, and is associated with deformity of the body and subluxation or dislocation of the facet joints at the injured level. [2]
The two main proposed mechanisms agree that neurovascular compression plays a role. The ischemic theory proposes that poor blood supply to the spinal nerve roots results in NC. In contrast, the venous stasis theory proposes that a combination of low oxygen levels and metabolite buildup are responsible due to venous backup at the cauda equina. [7]
CT scan (computed tomography) of the brain (without any iodinated contrast), is the initial imaging choice because of its high speed, good accessibility in hospitals, high sensitivity in detecting brain injuries or brain diseases, thus helping to triage patients in emergency department in a timely manner and urgent neurosurgical intervention ...
