Computed tomographic mammography (CTM).

Breasts of 724 patients were studied by physical examination, mammography, and computed tomographic mammography (CTM) using a scanner designed for evaluation of the breast. Among cases in which CTM was not accompanied by use of contrast material, there were 60 malignant lesions, of which 10% were missed by mammography, 32% by CTM, and 8% by both. Among cases where CTM was supplemented by a 50 ml injection of 75% contrast material, there were 63 malignant lesions, of which 14% were missed by mammography, 16% by CTM, and 3% by both. Among cases where CTM was supplemented by a 300 ml infusion of 30% contrast material, there were 41 malignant lesions, of which 7% were missed by mammography and 5% by CTM, but none by both. Clinically, 22% of the malignant lesions in the infusion series were occult. There were 44 benign lesions in patients studied with the infusion technique. With mammography 68% were suspicious for malignancy, and with CTM, 56%.

Computerized tomography in demyelinating disease of the young.

We have used computerized tomography (CT) to look for evidence of cerebral demyelination in children with progressive neurologic disorders. Fourteen patients with a clinical diagnosis of a demyelinating disorder were examined by CT, and five had CT findings suggesting cerebral demyelination. In two patients with a so-called myelinoclastic demyelinating disease, CT showed asymmetric, circumscribed areas of diminished radiodensity, and in three patients with a leukodystrophy, scans showed diffuse symmetric areas of low density in the centrum ovale. Autopsy examination in one patient confirmed the diagnosis of sudanophilic leukodystrophy and substantiated the abnormalities suspected from CT.

A statistical description of the normal computerized brain scan.

A total of 100 CT brain scans performed with an EMI head scanner were analyzed in order to define the statistical limits of normal. The statistical parameters are means and standard deviations. Frequency polygons of the attenuation coefficients for each of five brain slices have been constructed. The concept of the water to brain ratio is introduced.

Spinal cord vascular malformations with symptoms during menstruation. Report of two cases.

Two patients had the initial complaint of fluctuating paraparesis, which was most evident at menstruation. One patient had a semimonthly fluctuating deficit. Spinal cord compression and ischemia, secondary to the vascular mass, were considered the most likely mechanisms. Blood levels of estrogen and progesterone during the menstrual cycle may have had a contributory effect. Fluctuating spinal cord deficits associated with a consistent portion of the menstrual cycle should alert the physician to the possibility of an arteriovenous malformation of the spinal cord.

Computerized reconstructive tomography applied to breast pathology.

Breast tumors can be clearly defined from the surrounding breast parenchyma by the use of computerized reconstructive tomography. Certain types of fibrocystic mastitis also can be distinguished from tumors, but other types of fibrous mastitis and probably fibroadenomas may not be distinguishable from tumors unless contrast material is used.

Early experience with the EMI scanner for study of the brain.

Computed tomography of the head is highly accurate new radiologic technique for the evaluation of neurologic disease. Analysis of early cases indicates that the appearance produced by CT in some conditions is unique and that increasing experience allows the neuroradiologist to predict the position and nature of disease processes with greater accuracy.

The use of computerized transaxial tomography in the diagnosis of tuberous sclerosis.

Computerized transaxial tomography is a useful test for the recognition of tuberous sclerosis when this diagnosis has not been firmly established by clinical methods. In addition, computerized transaxial tomography may demonstrate the location of obstruction in patients with tuberous sclerosis who have developed signs of increased intracranial presure. These generalizations are supported by evidence from four patients investigated by this test.

Breast cancer detection today: an opinion.

The family physician, more than most other physicians, is faced with rapidly increasing demands for breast cancer screening. The old standby, physical examination, is now accompanied by mammography, xeromammography, and, more recently, thermography. In this paper, we present our opinion, based on the collective experience at the Mayo Clinic, regarding the use and effectiveness of the several modalities, including mammography, xeromammography, and thermography, available for detection of breast cancer today.
