Objective To evaluate the correlation of pathology with color Doppler flow imaging and spectral flow Doppler in breast lumps for raising the diagnostic rate of breast lumps.Methods One hundred and sixteen cases with breast lumps were examined by color Doppler ultrasonography in comparison with their pathological results.Results ① In the group of malignant lumps,peak wave of contractive period often appeared ahead; contractive waves rose and descend quickly; beginning wave of diastolic period often appeared below the middle point of descending wave of contractive period; the latest wave of diastolic period often did not appear or appeared contrast wave .② In the group of benign lumps,peak wave of contractive period often appeared normal; contractive waves rose and descend slowly; beginning wave of diastolic period often appeared above the middle point of descending wave of contractive period ;the latest wave of diastolic period often appeared.Conclusions Spectral flow Doppler is an important index in differential diagnosis of breast lumps.

Objective To explore the clinical value of prenatal ultrasound on detecting fetal spleen.Methods 1850 normal cases and 34 cases of splenic abnormalities,including fetal anemia(31 cases) and intrauterine infection(3 cases),were included.All fetuses underwent standard ultrasound fetal biometry,routine fetal screening and splenic length and thickness measurement.The ultrasonic imaging and the size of fetal spleen in the two group of fetuses were compared and relevant statistical analysis was performed.Results ①In 1850 cases,the fetal spleen visual rate under prenatal ultrasound was 98.1％.②Linear regression analysis showed that there was a linear relationship between the thickness,spleen diameter and gestational age(GA) with simplified equation as follows:splenic length (mm)=GA,splenic thinckness (mm) =GA×0.5-4.③ In the 34 abnormal cases,the size of fetal spleen were significantly larger than those in normal fetuses.Conclusions It is important to detect fetal spleen by prenatal ultrasound which can provide valuable information for the diagnosis of fetal anemia and intrauterine infection.
