“…With scanner I we obtained five images using each of two scanning windows in the phantom (designated "top" and "side" [diagonal] (Sobel operator) was used to identify potential edge points in each region of interest by measuring the change in gray level in vertical and horizontal directions across each pixel. 4 Figures 2 and 3 are representative 2D echocardiographic images of the phantom obtained with scanners I and 2, respectively. In both figures a regional variation in textural appearance is exhibited that illustrates the typical pattern we found: the image texture is discrete and "granular" in the near field and becomes progressively smoother and coalescent as we observe regions more distant in range.…”

A B S T R A C TMetastatic breast cancer is a disease of early breast cancer that usually occurs several years after the early breast cancer. Breast cancer is the most common cancer among Iranian women. According to the new statistics in Iran 6160 breast cancers are diagnosed in the country each year and 1063 cases lead to death. In this paper, epidemiology, diagnosis and treatment have been investigated. In this study, case-control clinical trials and open studies with adequate data were collected. Due to the higher risk of age group 40-49 years and the advent of advanced breast cancer in Iranian women, the early diagnosis and determination of the exact size of the tumor before surgery is important in choosing a therapy plan. The decision on the therapy of invasive breast cancer depends on several factors such as cancer stage, tumor size and type, pathological and cytological status of the tumor, the patient's opinion, the presence or absence of estrogen and progesterone receptors in the cytoplasm of tumor cells and so on.

“…Bei den von uns gewählten Kriterienausprägungen handelt es sich um eine Kombination von Schallauslöschphänomenen und Schallverstärkungen hinter einem sonographischen Herdbefund. Von Kobayashi (1975) wurde der sog. akustische Mittelschatten (acoustic middle shadow sign) beschrieben.…”

The use of sonography to diagnose pathologic changes of the breast is constantly increasing. It is well known that this method can be employed to distinguish cystic from solid processes. Of greater interest is the question as to the usefulness of sonography in prognosticating the pathology of such processes. This prognosis of pathology is linked to assessment criteria which are not uniformly defined worldwide and which are also applied differently. The study reported here--an evaluation of 755 sonographic focal findings--points out the possible distinctiveness of each individual assessment criterion and indicates the degree of confidence with which malignant and benign breast processes can be distinguished. There are statistically significant differences (p less than 0.0001) in the patterns of distinctiveness of all the assessment criteria mentioned depending on whether the processes are malignant or benign. The most important criterion is the edge contour. Every sonographic focus finding should be checked with regard to its edge contour, retrotumorous acoustic behavior, echo structure, and echo density. In the dynamic part of the examination, changes in the form and structure of the finding must be recorded. The authors estimate the changes of being able to distinguish malignant from benign processes on the basis of the above-mentioned criteria as good. The guide to the classification of echographic phenomena presented here may be of help to learners.
