摘要:

AbstractFive patients developed abdominal lymphoma an average of 89 months after successful renal transplantation. Sonographically, the lymphomas presented as bulky intraperitoneal masses or focal deposits in the liver. These lesions exhibited good sound transmission and intrinsic pattern ranging from sparse, soft echoes to coarse trabeculations. Prompt diagnosis of this serious late complication of renal transplantation is crucial.Indexing Words: Posttransplant lymphoma Abdominal lymphoma · Renal transplantation · Sonograph

摘要:

AbstractSerial ultrasound measurements of fetal growth were made during uncomplicated pregnancy in 28 time‐mated rhesus monkeys. Gestational sac (GS) size, crown‐rump length (CRL), biparietal diameter (BPD), head circumference (HC), head area (HA), abdominal circumference (AC), abdominal area (AA), and femur length (FL) were measured. Average longitudinal growth curves for each parameter were obtained from individual fetal growth curves. Data analysis indicated that the linear model was optimal for GS, CRL, HA, AA, and FL. The linear‐quadratic model was optimal for AC, and the linear‐cubic model was optimal for BPD and HC.Indexing Words: Fetal growth · Rhesus monkey · U

摘要:

AbstractThe findings from preoperative diagnostic ultrasound were compared with operative and pathologic findings in patients with ovarian cancer. Twenty laporatomies were diagnostic second‐look procedures and 21 were therapeutic procedures in patients with clinically evident disease. Ultrasound was more reliable in patients with clinically suspected disease, but a site by site analysis demonstrated it is insensitive for detecting prevertebral adenopathy less than 3 cm in size, thin, 1.5 cm omental plaques, 5 cm or smaller lesions involving the mesentery or bowel and peritoneal masses 2 cm or less in size. Ultrasound was most sensitive in the detection of mites.Indexing Words: Ovary Cancer Ultrasoun

摘要:

AbstractPeak Doppler frequency is an index of the severity of carotid stenosis. Variability in this measurement is examined through in vitro and clinical studies. In vitro studies, using a carotid flow model, show that observers locate a stenosis and interpret the peak frequency differently, and each observer uses a different probe‐vessel angle. Clinical studies support these findings. Comparison of 304 carotid Doppler studies with arteriograms demonstrates 90% overall clinical accuracy. Each observer has a consistent range of peak frequency measurements, yet the description of a discrete percent stenosis is limited by observer variability.Indexing Words: Doppler spectral analysis · Doppler ultrasound · Carotid art

摘要:

AbstractAn ultrasonic fetal head circumference curve was developed from a group of 1278 ultrasound examinations in 710 normal obstetrical patients. These data were then used to compare the accuracy of head circumference (HC) to last menstrual period (LMP) and biparietal diameter (BPD) for the prediction of an accurate expected date of confinement (EDC) and, thereby calculate gestational age. The mean error of the signed differences (2 standard deviation) for HC was ‐0.8 2 ± 11.1 days, which was statistically different from the mean error of ‐6.1 ± 10.6 days for BPD and ‐2.8 ± 17.8 days for LMP. HC may have an advantage over BPD in situations where head shape (cephalic index) is significantly altered.Indexing Words: Head circumference Biparietal diameter · Occipital frontal diameter · Expected date of c
