Objective　To establish the normal growth velocity of fetal liver length and compare them with those of intrauterine growth retardation, pregnant diabetes and maternal-fetal blood types imcopatible. Method　Three hundred and five normal pregnant women and 24, 10, 16 pathological pregnant women of intrauterine growth retardation (IUGR), gestational diabetes and maternal-fetal blood types incompatible respectively had ultrasonographic measurement of fetal liver length at 18 to 42 weeks′ gestation. Results　Normal fetal liver length has a linear relation to gestational age, and showed a significantly rapid increase after 28th week with a growth rate of 1.76 mm per week, and 1.00 mm per week before 28th week (P<0.05). The growth rate of IUGR group before and after therapy were 1.19 mm and 1.23 mm per week, significantly lower than those of normal group (P<0.05). The growth rate of pregnant diabetes group before and after therapy were 1.63 mm and 1.63 mm per week, no statistical significance with normal group (P>0.05). The growth rate of maternal-fetal blood types incompatible group before therapy was 1.98 mm, showed no difference with normal group (P>0.05), but after therapy, the growth rate of fetal liver was 1.38 mm per week, significantly lower than normal group (P<0.05). Conclusion　Dynamic measurement of fetal liver length can help us to understand whether the fetus grow well in uterus and whether the treatments are effective.

Treatment and the clinical outcome of patients with head and neck cancer are determined by accurate staging and assessment of the cervical lymph nodes for metastases is an important step of this process. Ultrasonography, ultrasonography-guided fine needle aspiration (FNA), CT, MRI and PET/CT are used in the assessment of cervical lymph nodes. Ultrasonography guided FNA is advantageous in ease of application, minimumal invasiveness to patients, and less contraindications. Combined with cell block and molecular biology, FNA can be an effective tool for the diagnosis. The present article reviewed the diagnostic value of ultrasonography guided FNA in cervical lymph node assessment in patients with head and neck cancer.

Objective To investigate the value of transvaginal contrast-enhanced ultrasonography (CEUS)in the diagnosis of adnexal masses.Methods Thirty patients with adnexal mass were examined by conventional 2D imaging and contrast tuned imaging(CnTI)technology.The results were compared with pathological results and the CEUS features wet concluded.Results There were 21 cases of benign adnexal masses and 9 cases of ovarian malignancies among 30 patients.The CnTI technology can distinguish between solid and cystic parts in masses.CEUS showed that malignant tumor had the high microvessel density and these vessels were irregular in shape.Partial malignant masses had the characteristic in-out phases in CnTI imagine.Conclusions Transvaginal CEUS is benefit to improve the accuracy of diagnosis of pelvic adnexal masses.

ObjectiveTo develop a new formula to estimate macrosomia weight and compared with published 25 formulas.Methods1153 fetuses including 239 macrosomia within one week of delivery were considered.Two-dimensional ultrasound measurements of the fetal biparietal diameter (BPD),head circumference (HC),abdominal circumference (AC) and femur length (FL) were performed and recorded by experienced sonographers.The birth weight were measured after the babies born.The formula finding group,1034 fetuses including 914 fetuses weighting less than 4000g and 120 macrosomia,were utilized to generate an overall regression formula by stepwise linear regression.120 macrosomia were used to established the formula for estimating macrosomic weight.As the training group,other 119 macrosomia were used to test the new formula and compared with other 25 existing formulas.ResultsThe new formula for whole weight was:lgBW =0.180 (HC) + 0.00628 (AC) - 0.00318 (HC)2 + 0.00173 (AC) (FL) +0.0000430(BPD)(HC)2.The new formula for macromia was:lgBW =0.730(BPD) -0.0375 (BPD)2 +0.000264(AC) (FL).The new method gave ( - 87.89 ± 230.95)g of estimation error and (4.4 ± 3.9) ％ of absolute percentage error,while the best existing formula provided (115.61± 345.09)g and (6.8 ± 5.4)％.With the new method,89.1％ of estimates fell within ± 10％ of the actual birth weight,while the best existing formula gave 75.6％.ConclusionsThe new formula was based on typical Chinese Han women,the error was lower and more suitable than those developed formulas for Chinese populations,especially for macrosomia fetuses.

ObjectiveTo evaluate the probability of the fetal heart scanning in first trimester(11 -14+6 week) by transabdominal ultrasonography.MethodsBy using advanced ultrasound machine with high resolution transabdominal probe,249 fetal hearts were scanned.Four chamber view,left and right outflow view,three vessels view were obtained.The successful observation rates of these views under different gestational age were recorded.For 18 pregnant women with suboptimal transabdominal scanning condition,transvaginal scan were supplemented.ResultsAmong 249 singleton fetuses with low risk of congenital heart disease,four chamber view was successfully visualized in 227 (91.2％),left outflow view in 125(50.2％),right outflow view in 102(40.9％),three vessels view in 98(39.4％).The successful observation rate of these four views increased with gestational ages.The successful observation rate of each view in successive gestational age showed remarkable difference (P ＜ 0.05).The four chamber view had the highest successful observation rate with 95％ after 12 weeks.After 13 weeks,left and right outflow views visualizing rate was above 85％.Transvaginal scanning can increase the four chamber view successful observation rate.For observation of other views,transvaginal scanning,however,showed no superior than transabdomial scanning.ConclusionsHigh resolution transabdominal probe can be used to perform the fetal hearts scanning in early trimester.It will benefit to find the fetal heart malformation.
