309 The diagnostic value of thyroid imaging reporting and data system combined with ultrasonic elastography for thyroid nodule
WU Liang, YAO Shu-xin, HE Dong-fang
Objective: To assess sonographic features of thyroid nodules associated with malignancy and to establish a scoring and categorizing method based on sonographic features. Methods: A total of 2 045 patients with 2 045 thyroid nodules were included and divided into 2 groups: benign(1 293) and malignant(752). First, 11 sonographic features, including shape, border, margin, internal content, echogenicity, microcalcifications, posterior echo, halo, vascularization distribution, vascularization degree, and SR, were defined, and all nodules were retrospectively evaluated. Second, the features associated with malignancy were selected by statistical analysis and were assigned weightings according to their odds ratios. Third, a total score for each nodule was obtained after the assigned weightings of the suspicious features were summed. Fourth, the malignancy rate of each total score was calculated. Then a modified version of the Thyroid Imaging Reporting and Data System (TI-RADS) was established with reference to the American College of Radiology’s Breast Imaging Reporting and Data System. Results: Six independent features associated with malignancy were a taller-than-wide shape, an irregular margin, solid internal content, marked hypoechogenicity and hypoechogenicity, microcalcifications and qualitative hard. The TI-RADS included 5 categories with different malignancy rates: category 3(≤2%), 4A(3%~10%), 4B(11%~50%), 4C(51%~94%), and 5(≥95%). Conclusions: A modified version of TI-RADS was established on the basis of the sonographic features with different weightings according to the relative risk of malignancy. This system could be of great use in predicting the nature of thyroid nodules in a quantified and standardized way and also helping clinicians decide on the clinical management.

MA Yu-feng, ZHANG Xin, ZHANG Wei, LIU Hong-Shu
Objective: To elucidate the evaluation of shear-wave elastography(SWE) in the residual breast cancer after neoadjuvant chemotherapy(NAC). Methods: 66 breast cancer patients receiving NAC were consecutively included. The means and maximum stiffness after NAC treatment were assessed by SWE. Correlations between the stiffness and pathological response quantized by residual cancer burden(RCB) were determined. Pathological complete response(pCR) was recorded and considered as gold standard. Diagnostic tests of the stiffness value evaluated by SWE were performed. Results: Correlations between the stiffness and pathological response were significantly positive. The maximum stiffness had significantly better overall diagnostic performance than mean stiffness regarding evaluating pCR, and the difference of diagnostic performance between maximum and mean stiffness was significant(P<0.01). Conclusion: The performance of maximum stiffness for evaluating the residual lesion of breast cancer after NAC is favorable, SWE may facilitate the personalizing treatment of breast cancer.

LIU Xue-jing, SHAN Yan-na, HAN Zhi-jiang
Objective: To explore the value of different sequences of 3T magnetic resonance in the differential diagnosis of benign and malignant breast tumors. To optimize the diagnostic performance of DCE-MRI and DWI by the threshold ADC values. Methods: A retrospective analysis of preoperative MRI images of 573 cases with 608 histopathologically verified breast lesions by surgery or biopsy were conducted. A reading method that adapted ADC thresholds to the assigned BI-RADS classification was developed. Sensitivity, specificity, diagnostic accuracy and the area under the curve(AUC) were calculated. BI-RADS-adapted reading was compared with previously published reading methods such as T1WI and T2WI, DWI, T1WI, T2WI and DWI, DCE-MRI in the same population. Result: The sensitivities of T1WI and T2WI, DWI, T1WI, T2WI combined with DWI, DCE-MRI and DCE-MRI combined with DWI were 78.2%, 66.2%, 92.4%, 78.4% and 94.9% respectively. And the specificities were 79.7%, 97.5%, 67.6%, 99.1% and 81.1%, respectively. The AUC was 0.783, 0.846, 0.909, 0.923 and 0.399, respectively. Conclusion: Non-enhanced sequences of 3T magnetic resonance have high sensitivity and low specificity, but it still has some clinical significance when the patient cannot do the DCE-MRI. Multi-parametric breast 3T MRI with BI-RADS-adapted reading improves diagnostic accuracy.

324 Analysis of risk factors for asphyxia caused by sputum retention after tracheal stent implantation
SHI Xiao-bao1, ZHAO Gang2, FEI Cheng2, SUN Ling-ling1
Objective: To investigate the risk factors of asphyxia caused by sputum retention and to analyze the correlation between the risk factors and the occurrence of asphyxia after stent implantation. Methods: A total of 110 patients with central airway obstruction or tracheal fistula who were encountered in author’s hospital during the period from Jan. 2011 to Jan. 2016 were enrolled in this study. Tracheal stent placement was performed in all patients. After the treatment, the patients were divided into two groups based on the occurrence of asphyxia caused by sputum retention. According to literatures, we choose risk factors such as gender, etiology, types of stents, infection and the history of radiotherapy. The data were compared between the two groups through the univariate factor and multivariate factor analysis to evaluate their correlations. Results: 18 cases(16.4%) showed sputum retention with asphyxia and died as a result of respiratory and circulatory failure. In all patients with asphyxia, univariate analysis suggests that stent type, pleural effusion, anemia and respiratory failure were the risk factors leading to asphyxia. Age, etiology, and the history of radiotherapy were not significantly different. Multivariate analysis showed that preoperative type Ⅱ respiratory failure was significantly related to the occurrence of postoperative asphyxia. Conclusion: The presence of preoperative type Ⅱ respiratory failure is a significant risk factor associated with asphyxia caused by sputum retention after tracheal stent implantation.

SHI Wei-ya1, HANG Jing-qing1, ZHANG Zhi-yong2, ZHANG Feng-ying1
Objective: To study the differences of CT quantitative parameters in the three phenotypes of chronic obstructive pulmonary disease(COPD), and correlations with pulmonary function parameters, so as to ascertain the clinical feasibility of CT applicative parameters. Methods: Ninety one patients with stable COPD underwent the paired inspiratory and expiratory HRCT scans and pulmonary function tests. The subjects were classified into the three phenotypes according to the rank of emphysema and with or without the bronchial wall thickening: A phenotype, E phenotype and M phenotype. The differences of pulmonary function parameters and CT quantitative parameters(%LAA-950ins、%LAA-856exp、RVC-856to-950 and E/I-ratio MLD) in the three phenotypes of COPD were analyzed. The correlations between CT quantitative and pulmonary function parameters were evaluated. Results: There were three phenotypes in this study: A phenotype(n=50), E phenotype(n=23) and M phenotype(n=18). The values of FEV1, FEV1% and FEV1/FVC were reduced successively in the A phenotype, E phenotype and M phenotype. The values of %LAA-950ins, %LAA-856exp, RVC-856to-950 and E/I-ratio MLD were increased successively in the A phenotype, E phenotype and M phenotype. In the A phenotype group, %LAA-950ins had no correlation with pulmonary function parameters, %LAA-856exp, RVC-856to-950 and E/I-ratio MLD had statistically negative correlations with pulmonary function parameters separately. Among them, E/I-ratio MLD had the strongest negative correlation with FEV1%(γ＝-0.588, P＝0.000). In the E phenotype and M phenotype groups, CT quantitative parameters had statistically significant negative correlations with pulmonary function parameters(P＜0.01). RVC-856to-950 had the strongest negative correlation with FEV1(γ＝-0.669, P＝0.000). Conclusion: CT quantitative parameters were different in the three phenotypes of COPD. CT index of emphysema(%LAA-950ins) and CT indexes of gas trapping (%LAA-856exp, RVC-856to-950 and E/I-ratio MLD) could be used as effective parameters for evaluating pulmonary function of COPD.

ZHANG Yi, LI Shen-yi, CHEN Hong-tian, LONG Xiang-dang, XIE Juan-juan, WU Yuan
Objective: To evaluate the twist parameters of left ventricular(LV) in heart failure patients with preserved ejection fraction(HFpEF) by speckle tracking imaging(STI), and to analyze whether the twist parameters have clinical value in assessing the changes of LV myocardiac mechanics in HFpEF. Methods: 63 HFpEF patients were analyzed the following twist parameters by STI: peak apical rotation(Par), Peak basal rotation(Pbr), Peak LV twist(Ptw), peak twist velocity(PtwV), percent time to peak twist(TPK%), peak untwisting velocity(PutwV) and isovolumic untwisting%(Iutw%). The correlation between twist parameters and conventional echocardiography parameters were also analyzed. Conventional echocardiography parameters includes LV End-diastolic diameter(LVDD), LV posterior wall(LVPW), interventricular septum(IVS), ejection fraction(EF), left atrial volume index(LAVI), peak of early diastolic mitral flow velocity(E), ratio of peak early diastolic and peak late diastolic mitral flow velocity(E/A), ratio of peak of early diastolic mitral flow velocity and early diastolic septal annular velocity(Ｅ/e＇). 40 healthy volunteers were included as the control group. Results: LVDD and EF of HFpEF group were within the normal limits (P＞0.05), but LVPW, IVS, LAVI, E, E/A, Ｅ/e＇ were all significantly different from the controls(P＜0.05). The twist parameters show that systolic Par and diastolic PutwV and Iutw% were significantly lower in HFpEF group(P＜0.05). Although Pbr, Ptw, PtwV, TPK% were decreased slightly, there is no significant difference compared with the controls(P＞0.05). There were significant positive correlation between PutwV and E/A, Ｅ/e＇, as well as Iutw% and E/A, Ｅ/e＇. There was a significant negative correlation between LAVI and PutwV, Iutw%. Conclusions: The changes of diastolic untwist parameters measured by STI can provide information about LV myocardiac function in HFpEF patients to help clinical diagnosis and treatment. Reduced Par in HFpEF patients can sensitively reflect myocardiac dysfunction, denoting some degree of subclinical systolic dysfunction in these patients.
