Transillumination light scanning for use in the detection of diseases of the breast. 1 UI - 87089425 AU - Linford J ; Shalev S ; Bews J ; Brown R ; Schipper H TI - Development of a tissue-equivalent phantom for diaphanography. AB - A phantom is proposed for quality control and calibration of instruments used for transillumination of the breast for early detection of cancer. A container is filled with a material having optical properties very similar to those of breast tissue, and internal objects are viewed by transmitted light. The phantom can be used to optimize operating conditions for the visualization of small or deep-seated lesions.

AB - Histologically classified carcinoma and benign breast disorder was present in 100 respectively 163 cases of symptomatic women. The results of diaphanography were correlated with those obtained by clinical examination, mammography and histology. A false negative diagnosis was made in 17 cases (15.5%) using diaphanography and in 13 cases (11.8%) using mammography. A false positive diagnosis was made in 15 cases (9.2%) with diaphanography and in 33 cases (20.2%) with mammography. The use of both mammography and diaphanography reduced the number of false negatives from 11.8 per cent to 5.5 per cent. In conclusion, diaphanography has been demonstrated to be a useful adjunct to mammography.

AB - A prospective study was done involving 822 women who had both film screen mammography and a breast transillumination light scan examination. The study population was not randomized; a modified phase-2 study was done. Mammography was superior for detecting malignancy: of the 67 pathologically proved breast cancers, 64 (95.5%) were detected by mammography and 45 (67.2%) were detected by transillumination. Biopsy revealed that 74 patients had benign lesions. In this group of patients, the false-positive rate was 12.2% for light scanning and 79.7% for mammography; however, 117 other patients had false-positive light scans.

State-of-the-art. AB - The underlying goal of all breast imaging procedures is the detection of cancer. X-ray mammography places greatest emphasis on the disclosure of early, nonpalpable, curable cancer. Diagnostic ultrasonography stresses the differentiation of benign cysts from diagnostically indeterminate solid masses that require biopsy. Evolving experimental procedures such as transillumination light-scanning and magnetic resonance imaging currently are undergoing preliminary evaluation. An older procedure, thermography, seems to operate at a high level of effectiveness only for advanced cancer. Since x-ray mammography is the technique that has proven most successful in detecting early breast cancer, it is the standard to which all imaging alternatives must be compared.

AB - Transillumination and Infrared Light Scanning (I.L.S.) of the breast were evaluated in a high referral breast clinic over a 15-month period. Seven hundred (700) patients were examined and blindly transilluminated; 101 were biopsied, all had mammography. The study was conducted in two phases: Phase I evaluated transillumination without I.L.S. This included 22 biopsied patients out of 101, with eight carcinomas identified histologically, demonstrating 87 per cent sensitivity and 64 per cent specificity for transillumination, versus 87 per cent and 71 per cent for mammography, and 87 per cent and 57 per cent for examination. Phase II evaluated simple transillumination combined with I.L.S. This included 79 biopsied patients out of 101 with 26 carcinomas identified histologically, demonstrating 96 per cent sensitivity and 74 per cent specificity for transillumination combined with I.L.S. compared to 85 per cent and 72 per cent for mammography and 81 per cent and 73 per cent for examination. Of the 26 Phase II carcinomas identified, two were not felt by examination, and two were neither felt nor read correctly by mammography. I.L.S. of the breast has proven effective in the hands of trained personnel and should be used with routine breast examination or mammography to increase yield of breast pathology.
