摘要:

AbstractThe use of a diagnostic system for ultrasonic liver tissue characterization based on computerized B‐mode image analysis is clinically tested and compared with the results of conventional realtime and static grey scale liver ultrasound as independently assessed by three experienced observers. The diagnostic classes, normal, diffuse parenchymal and malignant disease, are clearly differentiated by computerized image analysis which is superior to subjective evaluation of liver echograms. Computerized analysis also renders a reliable and clinically useful diagnostic subclassification of diffuse parenchymal disease into echopattern changes prevalent in chronic hepatitis, cirrhosislfibrosis, fatty infiltration and a mixed state of cirrhosislfibrosis with fatty infiltration which cannot be achieved by conventional liver ultrasoun

摘要:

AbstractBetween January 1 and March 31, 1983, 103 patients scheduled for prostatic surgery were blindly evaluated preoperatively by suprapubic real time sonography. Prospectively, the sensitivity was 72.7%, specificity 72.2%, predictive value of positive test 51.6% and predictive value of negative 86.7% for the detection of prostatic carcinoma. Retrospective analysis increased the sensitivity to 86% and when clinical information was utilized, only one carcinoma escaped detection. Unfortunately, both prostatic inflammation and occasionally benign prostatic hypertrophy may simulate carcinoma sonographically, thus producing a significant number of false positives. No ultrasonically detectable characteristics could be found which unequivocally separate carcinomas from inflammation and hypertrophy. For this reason routine suprapubic screening does not seem warranted.

摘要:

AbstractUltrasonic examination in 33 cases with threatened abortion at 8 to 17 weeks of pregnancy revealed an echo‐free crescent area between the fetal membranes and uterine wall regarded as an intrauterine hematoma. A living fetus was simultaneously detected in all patients. The duration of uterine bleeding (mean 28.8 ± 19.1 days) was significantly correlated (P<0.01) with the existence of the intrauterine blood collection followed serially by ultrasound, The pregnancy ended in spontaneous abortion in six (18.7%) and in premature delivery in three (9.4%) cases. The estimated volume of hematoma did not correlate with the outcome of pregnan

摘要:

AbstractWe evaluated nine patients, age 1 day to 17 years, having infantile polycystic kidney disease (IPKD). Using modern scanners with 5‐MHz transducers we have observed two previously unemphasized sonographic (US) findings, a peripheral zone of normally echogenic cortex (five patients), and mild caliectasis (two patients). Our data suggest that IPKD is a more heterogeneous condition clinically and sonographically than generally appreciated and that presence of a thick normally echogenic renal cortex is a good predictor of concurrent normal renal function and prolonged surviva
