We used texture analysis with the co-occurrence matrix method to analyze ultrasonograms from normal and diseased livers, and X-ray CT images obtained from normal cases and cases of idiopathic interstitial pneumonia. Ten cases of normal, fatty, and cirrhotic livers; 10 cases of normal lungs; and 10 cases of idiopathic interstitial pneumonia, all confirmed by(More)
We applied quantitative parameters in three-dimensional ultrasonic images to distinguish benign from malignant breast tumors in 29 benign cases including 8 cysts and 21 fibroadenomas, and 32 malignant cases including 23 ductal carcinomas, 2 special types of carcinoma, 1 malignant lymphoma and 6 others. This procedure involved simultaneously acquiring video(More)
We are developing a new method of breast cancer screening that we call Automated Breast Cancer Diagnosis (ABCD). This system uses computerized three-dimensional (3D) imaging techniques and statistical analysis to base diagnosis on data obtained from ultrasound images. Here we use this system to investigate ten parameters and their effectiveness in(More)
We used a real-time, ultrasound scanner to establish a reference interval of liver size in children based on their height and age. The study group comprised 476 children ranging in age from 1 month to 15 years. Maximal craniocaudal length (L1) and anteroposterior width (L2) determined in the longitudinal plane passing through the aorta were used as(More)
We ultrasonographically measured renal length in the major axis in children. Here we discuss the differences in measured lengths in the supine and prone positions. In study 1, which included 214 children, more than 60 percent of the kidneys measured longer in the supine than in the prone position. The difference (S-P: length in the supine position minus(More)
Case 1, Borrmann's type 2 carcinoma detected by endoscopy in the body of the stomach of a 59-year-old man. Total gastrectomy with spenectomy was performed. Histologic examination revealed a poorly differentiated adenocarcinoma with marked venous invasion. Follow-up ultrasonography showed the tumor thormbi in the splenic vein to be progressively distended to(More)
A 13-year-old girl was admitted to the hospital because of cardiomegaly found incidentally at regular medical checkup at her school. Although dilated cardiomyopathy was suspected, the girl showed no symptoms. chest x-ray film showed cardiomegaly (cardiothoracic ratio, 67%), and echocardiogram demonstrated a dilatation of the left ventricle without thinning(More)
