Objective: To investigate the distribution of deep medullary vein(DMV) in the transient ischemic attack(TIA) patients by using susceptibility-weighted imaging(SWI). Methods: MR images of 118 TIA patients and 32 healthy volunteers were double-blinded analyzed retrospectively. Two senior radiologists evaluated the image quality and DMVs symmetry at the same time, but evaluated DMV types respectively. DMVs showed identical areas in the lateral ventricles, amounts difference less than 5 and expanded similarly were defined symmetry. Kappa test were analyzed DMV types by two radiologists respectively. Contrasting superficial cerebral veins(SCV), DMV were defined in three types: type Ⅰ no visible DMVs; type Ⅱ DMVs<SCVs; type Ⅲ DMVs=SCVs. Thirteen volunteers of the control group had carried on the comparative study between two MR scanners(Siemens Verio 3.0T and GE Discover 750 3.0T). Results: The value of Kappa was 0.855 by two radiologists. By using Man-Whitney test, there was significant difference between DMV types of the TIA and the control groups(P=0.000, P
<0.05), there was also no significant difference between two groups of TIA(P=0.633, P>0.05). Fisher’s exact probabilities in 2×2 table was analyzed DMV symmetry of two groups(TIA and the health)(P=0.04, P<0.05). There was no difference in determining the DMV types between two MR scanners(χ2=0.5, P>0.05). Conclusions: DMV judgement of TIA patients had good consistency. DMV in the TIA could be asymmetric distribution and its diameter was much smaller than or close to SCV.

Objective: To analyze comprehensively the age, location, adjacent relationship and MR imaging features of space occupying lesions on the third ventricle region. Methods: Sixty-eight patients with space occupying lesions on the third ventricle region(confirmed by postoperative histopathology, following up) were reviewed in order to analyze their differences of the age, location, adjacent relationship and the MR imaging characteristics in this study. The correlationship between peritumoral appearance(periventricle extension, periventricle edema), MR imaging feature(T2WI, T1WI signal intensity, uniformity and enhancement pattern) and benign or malignant tumor was analyzed respectively. Results: Of 68 cases with third ventricle region tumor-like lesion(anterior part: 38 cases, upper part: 5 cases, posterior part: 16 cases, floor part: 3 cases, intraventricle: 6 cases), there included 14 non-neoplasm lesions and 54 tumor lesions(36 benign tumors and 18 malignant tumors). Germinoma, Langerhans cell histiocytosis(LCH) were seen commonly in children and adolescents; pituitary adenoma, papillary craniopharyngioma, hypothalamic-chiasmatic glioma and metastases were usually seen in middle-aged and old population; adamantinomatous craniopharyngioma were seen in 7 to 24 years old and 40 to 60 years old; the onset age of vascular lesions had no obvious specificity in our study. There was statistically significant difference between periventricle extension, periventricle edema and tumor malignancy, respectively(P<0.001). There was no statistically significant difference between T2WI, T1WI signal intensity, uniformity, enhancement pattern and tumor malignancy by single factor analysis(P>0.05). Conclusion: Comprehensive analysis of the age, location, adjacent relationship and imaging features of space occupying lesions on the third ventricle region may be helpful to improve their diagnoses and differential diagnoses, so as to guide clinical therapy.

Objective: To explore the feasibility of QontraXt software in carotid plaques by contrast-enhanced ultrasound(CEUS) on predicting ischemic stroke, and to analyze the relation between ischemic stroke and the characteristics of hypoechoic carotid plaque. Methods: Totally 114 patients with hypoechoic carotid plaque were filtrated from January 2010 to January 2013 in our hospital. The regular CEUS were performed and the data were analyzed by QontraXt software. The patients were followed-up for 3.1±0.8 years. Fifty-four patients with stroke were defined as the stroke group. Meanwhile, sixty patients without stroke were defined as the control group. The TIC curve and color enhanced image in the software were analyzed off-line. Results: Compared with the control group, the enhanced peak were significantly higher in the stroke group(34.04±4.82 vs 21.63±3.54; P=0.000). Plaques/arterial lumen enhanced intensity ratios(0.59±0.10 vs 0.46±0.18; P=0.000) in the stroke group were significantly larger. The sensitivity and specificity of enhancement figure prediction of ischemic stroke performed by QontraXt software was higher than the CEUS(35.18% vs 77.78%; 68.33% vs 90.00%). Conclusions: The quantitative analysis of carotid plaques by QontraXt software based on CEUS may help to predict the risk of ischemic stroke more precisely through the evaluation of plaque neovascularization.

Objective: To investigate the predictive value of plain CT scan in simple coarse calcific thyroid nodules(SCCN). Methods: The CT data of 92 SCCN in 92 cases confirmed by operation and pathology were retrospectively analyzed, including 57 benign nodules and 35 malignant nodules. The bone window(W 1 000~2 000 HU, L 300~350 HU) and soft tissue window(W 300~350 HU, L 35~40 HU) were used to identify whether SCCN had septa and peripheral artifacts, respectively. The number of benign and malignant nodules which had septa and artifacts were counted, followed by χ2 test for statistical analysis. Results: In 92 SCCN, the proportions of septa, no artifacts and their combination in the benign and malignant nodules were 50.9%(29/57) and 80.0%(28/35)(χ2=7.803, P=0.005), 26.3%(15/57) and 71.4%(25/35)(χ2=17.958, P=0.000), 3.5%(2/57) and 57.1%(20/35)(χ2=34.284, P=0.000), respectively. Their sensitivity and specificity of diagnosing malignant nodules were 80.0%(28/35) and 49.1%(28/57), 71.4%(25/35) and 73.7%(42/57), 57.1%(20/35) and 96.5%(55/57), respectively. The combination of no septa and artifacts in benign and malignant nodules accounted for 38.6%(22/57) and 5.7%(2/35)(χ2=12.162, P=0.000), respectively. Their sensitivity and specificity of diagnosing benign nodules were 38.6%(22/57) and 94.3%(33/35). Conclusion: CT scan for predicting benign and malignant SCCN was of significant value. Septa and no artifacts contributed to the diagnosis of malignant nodules, while no septa and artifacts suggested the diagnosis of benign nodules. Their combination could significantly improve the diagnostic specificity.

SUN Ting-ting, SUN Jia-xing, XIE Li-mei, WANG Bing, WANG Chao
Objective: To investigate the value of intelligent spatiotemporal image correlation(iSTIC) in researching normal fetal right heart ventricular volume and systolic function. Methods: From October 2014 to September 2015 in our prenatal ultrasound examinations of normal pregnancy, 167 cases of pregnant women were included. The application of iSTIC technology was to acquire the whole fetal cardiac volume data and the QLAB software was for off-line analysis. We defined cardiac systolic and diastolic phase by atrioventricular valve open and following atrioventricular value closure. Two phases of volumetric data were measured by manual tracting and summation of multiple slices, recording the right ventricular end-systolic volume(RESV) and the right ventricular end-diastolic volume(REDV). These volumes were used to calculate the right stroke volume(RSV), the right cardiac output(RCO) and the right ejection fraction(REF). Analysis of the relationship between the above-mentioned index changing with the gestational age(GA). In 30 randomly selected cases the right ventricular volume were measured by the same sonographer twice and the intraobserver agreement measurements were calculated. Results: Among 167 cases of fetal, 140 cases of application of iSTIC technology acquisition images clarity for later analysis, the successful rate was 83.8%.The mean REDV increased from (0.99±0.34) at 22 weeks to (3.70±0.35) at 35 weeks+6; the mean RESV increased from (0.43±0.18) at 22 weeks to (1.37±0.21) at 35 weeks+6; the mean RSV increased from (0.62±0.29) at 22 weeks to (2.32±0.19) at 35 weeks+6; the mean RCO increased from (92.23±40.67) at 22 weeks to (337.21±29.02) at 35 weeks+6. REDV, RESV, RSV, RCO were increased with the gestational age, there are linear correlation with gestational age(P<0.001). REF had no obvious correlation with GA(P>0.05). Conclusion: Application of iSTIC technology can quantitatively measure the fetal right ventricular volume, relatively simple operation, and high repeatability. iSTIC technology is expected to provide a new method for clinical evaluation of the fetal cardiac function.

812 Macrosomia primipara by different delivery way pelvic diaphragm in recent
LIN Chong1, WANG Xing-tian2
Objective: To investigate the short-term effects of different fetal macrosomia delivery methods on the morphology of the pelvic diaphragm hiatus in the primiparas. Methods: A total of 40 primiparous women were divided into postnatal normal newborn group(2 500~3 999 g, 20 cases) and postnatal fetal macrosomia group(≥4 000 g, 20 cases). Further, the whole 40 primiparas were grouped in the light of delivery way: postnatal normal newborn vaginal delivery group(10 cases) and caesarean group(10 cases), postnatal fetal macrosomia vaginal delivery group(10 cases) and postnatal fetal macrosomia caesarean group(10 cases). Perineal three-dimensional ultrasound was performed to observe the morphology and measure the parameters of pelvic hiatus at resting, pelvic muscle contraction and during maximum valsalva maneuver. Results: Regardless of the resting stage, anal stage and tension stage, the pelvic diaphragm hiatus anteroposterior diameter, left-right diameter, area and perimeter of the postnatal fetal macrosomia vaginal delivery group are greater than that of the postnatal fetal macrosomia caesarean group, postnatal normal newborn vaginal delivery group and postnatal normal caesarean group(P<0.05). The anteroposterior diameter, left-right diameter, area and perimeter in the anal stage and the area of postnatal fetal macrosomia caesarean group in the tension period are higher than postnatal normal caesarean group(P<0.05), with statistical significance. In the tension stage, the postnatal fetal macrosomia caesarean group diaphragm hiatus, left-right diameter, perimeter are greater than postnatal normal newborn vaginal delivery group and caesarean group(P<0.05), with statistical significance. Conclusion: Different ways of delivery have different influence on the primipara pelvic diaphragm pregnancy and childbirth are more likely to cause the change of the morphology and size of the pelvic diaphragm hiatus. Cesarean has less injury on pelvic diaphragm for first-time mothers than natural labor.

826 Clinical and imaging findings of intrapulmonary lymph node
TANG Li-ping, WU Jian-lin
With the appearance and rapid development of spiral CT technology, detection ability of micro and small lesions in lungs is increasing. The researches were lack of understanding in intrapulmonary lymph nodes(IPLN) in the past, which resulted in plenty unnecessary surgeries. Especially in case of lung cancer with IPLN which tended to be misdiagnosed as IPLN metastasis was more likely to cause excessive medical care. So it is significant to diagnose IPLN validly and accurately combined with clinical and imaging methods, exploring its imaging findings. The detection rate of IPLN is increasing with wide application of spiral CT. Clinical and imaging manifestation of IPLN were reviewed in this article in order to improve its preoperative diagnosis level.
