Computerized axial tomography

Neurology, 1975
Between August 1973 and April 1974 more than 750 patients had computerized axial tomography (CT) scans at the Massachusetts General Hospital. Ten brains from previously CT-scanned patients in this group were sectioned in the plane of the scan.

Direct coronal computerized tomography

Computerized Tomography, 1977
The computerized tomographic examination is routinely performed in the axial plane. However, with several available CT units images in the coronal plane are easily obtained. These images are especially useful in the diagnosis of diseases of the facial bones, sinuses, orbits and parasellar area.

Hazards of Computerized Tomography

Archives of Neurology, 1979
To the Editor.— The complications of diagnostic contrast radiography have not been sufficiently emphasized in the neurologic literature despite the fact that both cerebral arteriography and contrast-enhanced computerized axial tomography are frequently employed in the study of much intracranial disease. In addition to the wellknown risk of anaphylaxis,

Computerized tomography and encephalography

Neuroradiology, 1977
This preliminary paper compares encephalography and computed tomography as regards the duration of the examinations, the technical difficulties and their diagnostic values. Some examples are reported to demonstrate the complementary importance of the two techniques.

Computerized tomography in Multiple Sclerosis

Journal of Computer Assisted Tomography, 1980
Forty-three patients with multiple sclerosis (MS) were examined clinically and with computerized tomography (CT). A total of 80 focal cerebral lesions were predicted by clinical neurologic examination. The CT scans showed foci corresponding to 31 (39%) of the clinically predicted 80 lesions.

Computerized tomography in ovarian cancer

Gynecologic Oncology, 1983
Sixteen women suffering from ovarian cancer were staged by clinical and pathological means and concomitantly scanned by computed tomographic means. Computed tomography (CT) was found accurate in nine patients. The staging of the disease was upgraded in three patients following the CT examination.

Aliasing artifacts in computerized tomography

Applied Optics, 1979
Streaking artifacts in tomographic images reconstructed by the filtered-backprojection algorithm are caused by aliasing errors in the projection data. To show this a computer simulation study was performed in which the transforms of undersampled projections were subtracted from the corresponding transforms when the projection data were taken with a ...

Contrast-Enhanced Computerized Tomography

Archives of Internal Medicine, 1978
In this issue of theArchives(p 628) Heath et al describe a patient in whom cerebral abscesses were eventually documented by computerized tomography (CT). Using this technique, which has been thoroughly described in the literature, they at first did not diagnose the lesion, then later they did identify at least one abscess after the patient had been ...

Computerized-tomography: Isotope sources

International Journal of Radiation Oncology*Biology*Physics, 1977
Abstract Recently pure rotary fan beam computerized tomography (CT) body scanners have been successfully demonstrated by Artronics, AS&E, GE and Varian. These scanners have the large solid angle detection efficiency required by proposed practical isotope source-based CT scanners.
