Thermography in the Diagnosis of Breast Cancer

Abstract: Although it has been demonstrated that thermography is capable of revealing most large breast carcinomas, its ability to detect and localize “occult” or preclinical lesions is still unknown. The accuracy of the method as compared with mammography also remains in question. In June 1964, a Pyroscan4 was made available to the Department of Radiology, Jefferson Medical College Hospital. A comparative study was initiated, utilizing a serial group of patients referred primarily for mammography. Although a high proportion of specific breast abnormalities was anticipated, the material was expected to be sufficiently diverse to provide some indication of the utility of the procedure from the standpoint of detection and mass screening. Literature The literature on surface temperature determinations as a method of detecting breast carcinomas is limited. In 1956, Lawson (5) reported a series of skin temperature measurements made with a contact thermometer over known carcinomas of the breast. In 1957 he described the ...

Roentgen Appearance of Fat Necrosis in the Breast

Abstract: With increasing acceptance of mammography as a useful adjunct in the diagnosis of breast disease, more mammograms are being obtained throughout the country, and as experience is gained in this relatively new discipline, the pitfalls of mammographic diagnosis are increasingly recognized. The roentgen appearance of some benign disease processes may simulate and be easily confused with that of carcinoma. In Egan's original series (2) of 2,000 consecutive mammograms, for example, 11 of 30 breast abscesses were misinterpreted as malignant lesions. Other sources of false diagnoses in this series included sclerosing adenosis, fibrocystic disease, fibroadenoma, and fat necrosis. The present communication deals with the last entity, of which 3 cases have come to our attention. In each instance a false positive diagnosis of malignant tumor was made from the mammograms. Case Reports Case I: This 66-year-old woman had noted a small lump in the upper outer quadrant of the left breast three weeks before admission. Two ...

The venous diameter ratio in the radiographic diagnosis of breast cancer.

Abstract: Increased vascularity is a secondary sign in the roentgen diagnosis of breast cancer. Although many radiologists remain dubious of its value, Egan(1, 2) believes that the finding has diagnostic significance in about 50 per cent of cases. Our interest in this particular aspect of mammography was stimulated by a comparative study of 1,000 consecutive cases in which both mammography and thermography were performed. Unilateral prominence of the superficial veins was observed to be a useful criterion in the thermographic diagnosis of cancer. For this reason, a review of this series of cases was initiated to determine whether a correlation existed between vessel size and the presence of abnormal thermographic signals. Although unilateral vessel prominence was sometimes obvious, no marked difference was apparent in most cases. Therefore, a simple method of measuring the comparative diameters of the superficial veins was devised. Although certain technical factors inherent in mammography tend to minimize the prec...

Mammogram Screeners: Modified Program Learning for Nonradiologic Personnel1

Abstract: Carcinoma of the lung and carcinoma of the breast are two main categories of malignant tumors that are increasing in incidence in the United States. Breast cancer is the number one malignant tumor of adult women in this country: 1 out of every 19 American women will be affected by this disease. The death rate from breast cancer has been stationary for about twenty-five years. The widespread use of mammography, especially in the screening of asymptomatic patients, has been attempted in an effort to detect preclinical lesions and thus favorably alter this death rate. Although mammography survey examinations have been performed on large segments of the female population, the results in the detection of occult lesions have been disappointing (1–3). The case-finding rates are very low, but when one considers that many unexamined women have detectable and surgically amenable lesions, the advisability of examining them is increased. When one includes persons over the age of fifty years who have a strong family h...

Roentgenography of breast specimens: An aid in the management of nonpalpable breast carcinoma☆

Abstract: In cases of nonpalpable cancer of the breast detected by mammography, specimen-roentgenograms are an extremely useful tool whereby surgeon and pathologist can be assured that the suspicious area of the breast has been excised A technic for obtaining roentgenograms of the specimen is outlined

Mammography: A progress report

Abstract: 1. 1. Mammography is becoming an important adjunct to diagnosis of early cancer of the breast, as well as an aid in differentiating between benign and malignant lesions of the breast. 2. 2. Mammography has definite limitations and does not in any circumstance replace the advantages of surgical biopsy. Biopsy is imperative if the mammogram reveals a significant shadow. 3. 3. Mammography should be reserved as an aid in the management for those patients with specific indications of breast disorder. 4. 4. If the mammograms give negative or inconclusive results, surgical exploration and biopsy are necessarily predicated upon the clinical evaluation of the affected breast. 5. 5. If mammography is to gain wide acceptance and succeed in hospitals around the country, the team approach must be used. Such a team is composed of the surgeon, radiologist, and pathologist. The radiologist, of course, is the key to a successful program through his efforts and ability to give good service and to give reports of meaningful value. Mammography is not just the taking and reporting of films. 6. 6. Mammography has become a permanent diagnostic aid, and through continued improvement in technics, films and x-ray equipment, complemented by the team approach, it gives every indication of adding to the control of cancer of the breast.

Mammography—a radiological challenge

Abstract: It was a privilege to read the Editorial in The British Journal of Radiology, 40 (No. 478), October, 1967, pp. 721–723, entitled “Mammography—A radiological challenge”. It stated the case for mammography with unusual clarity, while being careful also to list some of its problems.
