Computed Transaxial Tomography (CT) of Lumbar Spine

Computed tomography in the postoperative lumbar spine.

A retrospective review of computed tomograms (CT) was performed in eight patients who underwent surgery for presumed reherniation of a lumbar disc. The CT scan in the three patients with surgically proven extradural scarring and no disc herniation, demonstrated distinct characteristics of perineural fibrosis which differed markedly from the uniform changes seen on the scans of the five patients...

Low-dose computed tomography of the abdomen and lumbar spine

Muhammed Alshamari (2016): Low-dose computed tomography of the abdomen and lumbar spine. Örebro Studies in Medicine 137. Radiography is a common radiologic investigation despite abundant evidence of its limited diagnostic value. On the other hand, computed tomography (CT) has a high diagnostic value and is widely considered to be among the most important advances in medicine. However, CT expose...

Computed tomography and myelography of the postoperative lumbar spine.

Postoperative myelographic changes in the thecal sac, epidural tissues, and bony canal, as well as nerve roots, may be difficult to interpret. A series of 32 postoperative patients, all of whom had a metrizamide myelogram and subsequent lumbar computed tomogram, was reviewed to examine the ability of computed tomography to recognize abnormalities when the myelogram is equivocal or uninterpretab...

Computed Tomography of the Spine

Computed tomography and positron emission transaxial tomography evaluations of normal aging and Alzheimer's disease.

Young normal subjects, old normal subjects, and patients with senile dementia of the Alzheimer's type (SDAT) were studied with both computed tomography (CT) and positron emission transaxial tomography (PETT). Increases in ventricular size with both aging and disease were measured. Regional glucose metabolic rate was not affected by age, but was markedly reduced in SDAT patients. These data indi...
