Impact of computerized tomography on neuroradiological investigations in South Australia.

Although there has been a reduction in cerebral angiographic (33%), pneumoencephalographic (70%) and radionuclide brain scanning (28%) investigations since the introduction of computerized tomography in South Australia, there has been a significant increase (56%) in the total number of neuroradiological investigations performed. At the same time, the number of patients who underwent neuroradiological investigations has risen by 75%. This is equivalent to approximately one person in every 290 per year.

Computer-assisted tomography in the assessment of cervical spine trauma.

Four patients with cervical spine trauma were examined by computerised tomography in addition to standard radiography and additional useful information was thereby gained. The axial projection is particularly useful in studying the cervical spinal canal and neural arch. The examination may be performed rapidly without moving the patient, an important consideration after severe trauma.

Computed tomography of abdominal aortic aneurysms.

Computed tomography is an excellent non-invasive method for visualization of the size and extent of abdominal aortic aneurysms. It demonstrates the size of the lumen and the amount of thrombus in the aneurysm, and detects complications such as dissection and leakage.

The significance of widening of the presacral space at contrast radiography in inflammatory bowel disease.

The width of the presacral space was measured prospectively at various levels in 100 persons without organic colonic or rectal disease who had barium enema X-ray examinations. A standard technique was employed. The most consistent measurement was obtained at the level opposite the S3-S4 disc space; readings varied between 2 mm and 16 mm. Using 16 mm as the upper limit of normal, and a similar technique of barium enema examination, the width of the presacral space at the S3-S4 disc level was measured in 66 patients with inflammatory bowel disease (ulcerative colitis--49; Crohn's colitis--17). The width did not correlate with the severity of the disease process as indicated by sigmoidoscopic examination in proximity in time to the radiological examination. There was a relationship between increased width of the presacral space and the duration of the disease process.

The radiology of thoracic disc protrusion.

The radiological features of 20 surgically proven thoracic disc protrusions are reviewed. In 15 (75%), characteristic plain film changes were found to be very helpful in making the correct diagnosis. Calcified disc material in the spinal canal was clearly demonstrated in 11 (55%) cases, and this, in association with linear calcification in the adjacent disc space, has been shown to be diagnostic of the condition. At myelography, central protrusions (55%) were found to be predominant, while lateral protrusions were uncommon. The differential diagnosis of a calcified lesion in the spinal canal includes thoracic disc protrusion, osteochondroma and meningioma.

Radiology in the diagnosis of colloid cysts of the third ventricle.

A series of 38 cases of colloid cyst of the 3rd ventricle is described in most of whom the diagnosis, important for curative surgery, was made radiologically. The most useful investigative technique was pneumography, by which the tumour was outlined in almost all cases. The lateral "hanging head" projection generally demonstrated the lesion most satisfactorily. Care in manipulating air introduced at ventriculography through the foramina of Monro into the 3rd ventricle was frequently rewarded by clear definition of the tumour. In more than one-third of the cases, the lateral plain skull radiograph showed truncation of the dorsum sellae indicative of chronic obstructive hydrocephalus, and, in the large majority of these, pneumography confirmed that the 3rd ventricle, rather than the interventricular foramen, was the site of obstruction to the drainage of cerebrospinal fluid. Carotid angiography, showing hydrocephalus, and in the same cases elevation and lateral displacement of the anterior portion of the internal cerebral veins yielded strong supportive evidence. Vertebral angiography was less specific, and isotope scanning was quite unhelpful.
