摘要:

AbstractRetrospective analysis was performed for 56 breast masses with mixed cystic and solid sonographic patterns encountered in the last 5 years at Keio University Hospital, with the objective of elucidating their significance. The lesions were classified into two major groups: tumor with cyst (TWC—solid mass with cystic component) and intracystic tumor (ICT—cystic mass with solid component). According to the pathological diagnosis, 57% were benign and 43% were malignant. Fifty eight percent of malignant lesions were shown to have a TWC pattern and 42% an ICT pattern. Among benign lesions, 66% were shown to be TWC and 34% ICT. In malignant tumors, 96% of the cases showed irregular shape and heterogeneous internal content. Even in benign lesions, a high incidence of irregular shape and rough border was found, although the predominant internal echo texture was homogeneous, and threedimensional (3‐D) contour was not clear. In conclusion, we observed that in the TWC group, the lack of a defined 3‐D contour is the most important criterion, and tumors with multiples cysts tend to be benign. © 1993 John Wiley&S

AbstractWe present a new percutaneous ultrasound‐guided galactography technique that may be used in patients in whom the conventional technique fails and breast ultrasonography shows dilated ducts. © 1993 John Wiley&Sons, I

摘要:

AbstractSonographic evaluation of the pelvis of postmenopausal women is not complete until both ovaries are scanned. Transvaginal sonographic examination combined with transabdominal screening is diagnostic in 85% of cases. Transvaginal examination performed with a partially full bladder significantly increased ovarian detection to 93.5% (p<0.05). © 1993 John Wiley&Sons, Inc

摘要:

AbstractThe effect of heart rate on Doppler indices in the renal artery was studied in 21 nonpregnant, 17 normal and 27 preeclamptic pregnant patients. The central hemodynamics was evaluated by Doppler ultrasound in all pregnant women. The study demonstrated no influence of heart rate on renal artery Doppler indices. Central hemodynamic parameters, such as cardiac output, stroke volume, mean arterial pressure and total systemic resistance did not change with increasing heart rate. We do not recommend any correction of the renal artery Doppler indices for heart rate in the range considered clinically normal (60 to 95 beats/min). Above or below this range further investigations are required to determine if corrections would be necessary. © 1993 John Wiley&Sons, Inc

摘要:

AbstractNineteen transvaginal, sono‐guided ovarian cyst punctures were performed in 18 patients. These patients, who were high surgical risks, were diagnosed to possess benign ovarian tumors as revealed with sonography. Aspiration curettage of the inner surface of the cyst present during aspiration was also performed to facilitate cytologic diagnosis. The recurrence rate was 11.1%. Sono‐guided transvaginal cyst aspiration has been demonstrated here to be the treatment of choice for dealing with an ovarian cyst in patients at high surgical risk. © 1993 John Wiley&Sons,

摘要:

AbstractStandard ultrasound measurements were performed by two observers in 40 third‐trimester fetuses. Observers were blinded to the results of the meaurements. Estimated fetal weight (EFW) was calculated using two published formulae. The intra‐observer standard deviation for EFW, assessed using one‐way analysis of variance, was<75 g for both observers. The 95% prediction intervals for inter‐observer comparisons of EFW, calculated using the limits of agreement method, were − 187.3 g to 139.8 g, and − 159.9 g to 124.3 g, using the two formulae. The results suggest that measurements of EFW are reproducible. The prediction interval is comparable to the weekly fetal weight increment in normal fetuses. © 1993 John Wil

摘要:

AbstractColor Doppler imaging was employed to assess the uteroplacental circulation in abnormal first‐trimester gestations. Included in the study were 40 blighted ova, 35 missed abortions, 10 trophoblastic diseases, and 3 ectopic gestations. Normal gestations served as a control group. Flow was detected more frequently in the blighted ova than in the missed abortions. Flow was detected in all cases of trophoblastic disease and ectopic gestations. Resistance to flow was significantly lower in the trophoblastic group as compared to the other groups. © 1993 John Wiley&Sons, I
