ZHAO Ni, GAO Xi-can, SHU Rui, WU Jian-feng, SONG Hong-ping
DOI: 10.12117/jccmi.2019.07.001
Objective: To explore the clinical value of automated breast ultrasound system(ABUS) combined with handheld ultrasonography(HHUS) in the differential diagnosis of BI-RADS-US 3~5 among 1 463 cases of benign and malignant breast lesions. Methods: 1 463 breast lesions with BI-RADS 3 followed-up for more than 2 years and BI-RADS 4 and 5 confirmed by surgery or needle biopsy were selected. HHUS and ABUS were performed before operation to obtain 2D images, 3D volume data and the BI-RADS classification. Corresponding to the pathology as the gold standard, ABUS combined with HHUS was used to evaluate the diagnostic efficacy of BI-RADS 3~5 in benign and malignant breast lesions. Results: Among 1 463 cases of breast lesions, 935(63.9%) were benign and 528(36.1%) were malignant. ①According to the ACR version 5 BI-RADS-US classification guidelines, using pathology as the gold standard, the combined diagnostic evaluation of BI-RADS classification and pathological results compared with results by two examination methods(Kappa value=0.85) was higher than that of HHUS(Kappa value=0.81), with statistical significance(P<0.05). Comparing the two methods to assess the risk range of BI-RADS 3~5 categories of malignancy: the probability of 3 type malignancy decreased while the combination of both 0(0) vs. HHUS 0.3%(2/685); 4A type of malignant probability decreased while the two combined 3.4%(5/146) vs. HHUS 13.6%(22/162); 4B malignant probability decreased while the two combined 57.6%(95/165) vs. HHUS 60.1%(98/163); the probability of 4C type of malignancy increased while the combination of the two 84.2%(139/165) vs. HHUS 81.4%(131/161); the probability of 5 type of malignancy increased while the two combined 99.3%(298/291) vs. HHUS 94.2%(275/292). ②The diagnostic efficacy of ABUS combined with HHUS or HHUS alone in the evaluation of benign and malignant breast lesions were: sensitivity(99.05% vs. 95.45%), specificity(89.52% vs. 88.02%), accuracy(92.96% vs. 90.70%). Positive predictive value(99.41% vs. 97.17%), negative predictive value(84.22% vs. 81.82%), false negative rate(0.95% vs. 4.55%) and false positive rate(10.48% vs. 11.98%), area under ROC curve(0.95 vs. 0.91, P<0.001), which is statistically different(P<0.001). Conclusion: Compared with HHUS alone, AUBS combined with HHUS has the ability to accurately estimate the risk of malignancy in BI-RADS 3~5 lesions, especially BI-RADS 4 lesions, which helps to improve the diagnostic efficiency of BI-RADS classification, reduce misdiagnosis, reduce diagnostic errors, and facilitate the early detection of atypical abnormal lesions, and provide more meaningful imaging evidence for distinguishing breast benign and malignant nodules, clinical puncture options, and postoperative evaluation.

LIU Jie, WANG Rong, WANG Xing-tian, SHA Yu-meng, HUANG Rui, WANG Yu-qiao
DOI: 10.12117/jccmi.2019.07.002
Objective: To evaluate the application value of virtual touch tissue imaging(VTI) and virtual touch tissue imaging quantification(VTIQ) in differential diagnosis of small solid mammary nodules(diameter ≤10 mm). Methods: A total of 52 patients with 60 small solid mammary nodules from Breast Surgery Department in our hospital all underwent the routine ultrasound examination firstly, and the nodules were classified by BI-RADS. Then the VTI and VTIQ examinations were performed. The hardness scores of nodules were obtained by VTI. The shear wave velocity(SWV) values of nodules were obtained by VTIQ. The ROC curve was drawn to obtain the cut-off value of the small solid mammary nodules by VTIQ by using pathological diagnosis as the gold standard. The diagnostic value of BI-RADS classification, VTI and VTIQ for the benign and malignant small solid mammary nodules was evaluated. Results: The proportion of malignant group of the small solid mammary nodules(16/18) whose VTI hardness score ≥4 was significantly higher than that of the benign group(11/42). The mean SWV of the malignant group (6.37±1.96) m/s was significantly higher than that of the benign group (3.38±1.27) m/s. The difference was statistically significant(P<0.05). The cut-off value of SWV by VTIQ was 4.58 m/s for the diagnosis of small solid mammary nodules. The area under the ROC curve of BI-RADS classification, VTI and VTIQ was 0.720, 0.860, 0.924, respectively. The difference between every two group was statistically significant(P<0.05). Conclusions: VTI and VTIQ conduce to evaluate and differentiate small solid mammary nodules. VTIQ has more important clinical application value in judging the benignity and malignity of small solid mammary nodules.

DOI: 10.12117/jccmi.2019.07.003
Objective: To investigate the relationship between the respiratory rate and the scanning pitch when performing chest CT scan and evaluate their effect on image quality and radiation dose. Methods: Eighty-five patients were divided into group A and B randomly. According to their respiratory rate, patients in group A were divided into A1 and A2 group; patients in group B were divided into B1 and B2 group. In group A, high-pitch mode CT scan was performed; in group B, low-pitch mode CT scan was performed. The CTDIvol and DLP were recorded, and the image quality was evaluated subjectively and objectively. Results: Image quality of group A was better than that of group B; the difference was more obvious in A1 and B1 group; the CTDIvol was not significantly different in group A and group B, but the mean DLP value was 18.5% higher in group A than group B. Conclusion: Low-pitch mode CT scan was more suitable for low RRs patients when performing chest CT scan, that will reduce radiation dose while maintaining preferable image quality. Low-pitch mode CT scan was more suitable for low RRs patients when performing chest CT scan, which will reduce radiation dose while maintaining preferable image quality.

WU Qian-qian, LIU Hong-sheng, CHEN Yuan-kai, KUANG Min-wei, LIU Zhen-qing
DOI: 10.12117/jccmi.2019.07.005
Objective: To investigate the application of DWI in placenta implantation(PIA), and to compare the difference of the sequence between MRI at 1.5T and 3.0T. Methods: A retrospective analysis was carried out by analyzing 148 cases of suspected placenta previa with completed 1.5T, 3.0T MRI and B-ultrasound examination in Guangzhou Women and Children’s Medical Center from August 2016 to August 2018, using surgical and pathological results as the gold standard, and further comparison and analysis were performed focusing on the signal-to-noise ratio(SNR), apparent diffusion coefficient(ADC) value and the diagnostic accuracy indexes(sensitivity, specificity, false positive rate, false negative rate, etc.) of different types of placenta implantation. Results: The SNR of MRI at 3.0T was better than that at 1.5T under the same thickness. When b=50, the SNR of 3.0T at a thickness of 4 cm was lower than that of 1.5T at the thickness of 5 cm. Besides, when b=800, there was no significant difference between the SNR of 3.0T at 4 cm and that of 1.5T at 5 cm. Furthermore, the ADC values of the implanted part of the two models were higher than those of the non-implanted part, and there was no significant difference between the two models. Meanwhile, the diagnostic accuracy of 3.0T MRI was better than that of 1.5T MRI. Conclusion: DWI is helpful for definite diagnosis of placenta implantation. 3.0T MRI is superior to 1.5T MRI on the accuracy of PIA and the SNR of DWI sequence. It is more likely to recommend 3.0T MRI for placental examination on the premise of controlling total scan time.

DOI: 10.12117/jccmi.2019.07.007
Objective: To analyze and discuss the prenatal MRI features and diagnostic value of the fetal cavum septum pellucidum and its associated neurological abnormalities. Methods: From June 2015 to June 2018, 2 361 cases of fetuses from Sichuan Provincial Women and Children Hospital were included in our research. All the fetuses received 1.5T MR and ultrasonography(US) examination. We gathered the clinical information and analyzed the MR imaging. Results: 332 fetuses detected by MRI examination of fetal head revealed cavum septum pellucidum and associated nervous system abnormalities. In these cases, ultrasonography indicated 212 cases of cavum septum pellucidum. The age of the maternal and gestational week was 17~41 years old and 21~39W+3, respectively. MRI presented 221 cases of fetuses with pure cavum septum pellucidum abnormality, including 8 of complete absence of cavum septum pellucidum, 7 cases of partial absence, 92 cases of broadening, and 114 cases of narrowing. One hundred and eleven cases of fetus with cavum septum pellucidum anomaly combined with other neurological abnormalities, including 68 cases of corpus callosum complete absence, 16 cases of corpus callosum partial absence, 3 cases of visual-septal dysplasia, 9 cases of holoprosencephaly（HPE, including 2 alobar HPE, 2 semilobular HPE and 5 lobar HPE), 3 cases of Schizencephaly, 4 cases of brain injury, 4 cases of hydrocephalus, 2 cases of multiple malformations and 2 cases of porencephaly. Conclusions: MRI findings and presentations of fetal cavum septum pellucidum and combined neurological abnormality were characteristic. MRI has obvious advantages over US, which can manifest fetus central nervous system abnormalities not detected by US. MRI can diagnose more accurately and improve the accuracy of prenatal diagnosis of fetal central nervous system abnormalities so that reduce the birth rate of children with major defects.

SHANG Hong-lei, ZHAO Xin, ZHANG Xiao-an, LU Lin, ZHU Gong-sheng, GUO Ya-fei
DOI: 10.12117/jccmi.2019.07.009
Objective: To investigate the value of MRI in the prenatal diagnosis of abnormal fetal urinary tract. Methods: Forty-six fetuses with suspected urinary anomalies detected by routine ultrasound screening were rescanned by MRI to refine the diagnosis. All examined fetuses are single fetuses. The pregnancy outcome was examined externally by postnatal ultrasonography or MRI. Results: The average gestational age of 46 pregnant women was 28 weeks(range 20~39) and the mean maternal age was 26 years(range 21~40). Among 46 fetuses with congenital urinary system abnormalities, 30 cases had normal amniotic fluid volume(normal amniotic fluid group) and 16 cases had oligohydramnios(oligohydramnios group). The ratio of lung signal intensity to liver signal intensity(LLSIR) of oligohydramnios grpup was assessed by MRI to determine if there was fetal lung dysplasia. MRI diagnosis changed the preceding US diagnosis in 5 cases and added information in 12 cases. MRI confirmed US diagnosis in 4 fetuses. The prenatal US diagnosis was accurate and MRI diagnosis was incorrect in 2 cases, and prenatal US and MRI diagnosis were both not correct in 1 case. MRI showed 93.5%(43/46) accuracy in diagnosis while US showed 73.9%(34/46) accuracy. Oligohydramnios group were all complicated with pulmonary dysplasia and had a mean LLSIR of 1.01～1.87 and was obviously less than that in normal fetuses of similar gestational age(P=0.000<0.05). Conclusion: MRI is valuable in evaluating suspected fetal urinary tract abnomalies, especially when ultrasound is inconclusive owing to oligohydramnios.

DOI: 10.12117/jccmi.2019.07.010
Objective: To investigate the value of MRI in the prenatal diagnosis of abnormal fetal spine and spinal cord. Methods: Eighty-nine cases of single fetus, with suspected spine or spinal cord. Abnormal development detected during routine ultrasound screening, were rescanned by MRI to compare the diagnosis. All fetuses included are single fetuses at an average of 28 weeks of gestation(range 22~39) and the mean maternal age was 27 years(range 21~41). The MRI protocol was as follows: T2WI included half-flourier acquisition single-shot turb spin-echo(HASTE) and true fast imaging with steady state precession (True FISP), and T1WI used fast low angle shot in the axial(FLASH). Partial fetal underwent scanning with 3D-SWI. The pregnancy outcome was examined externally and by postnatal ultrasonography or MRI. Results: Eighty-nine fetuses contains 26 cases of vertebral dysplasia, 24 cases of spinal cord dysplasia, and 35 cases of vertebral complex malformation. The diagnostic accuracy of prenatal MRI was 100%(26/26), 91.7%(22/24), 85.7%(30/35), respectively, while the diagnostic accuracy of prenatal US was 88.5%(23/26), 45.8%(11/24), 45.7%(16/35) respectively. MRI showed higher diagnostic accuracy rate than US(P<0.05) in vertebral dysplasia while no significant difference in spinal cord dysplasia or vertebral complex malformation(P>0.05). Conclusion: Prenatal MRI is effective in the assessment of fetal spine and spinal cord dysplasia, especially in dysplasia of spinal cord. Prenatal MRI, especially with SWI sequence, has a promising application prospect in prenatal diagnosis of fetuses.

507 Research of fetal 3D volumetric MRI
DOI: 10.12117/jccmi.2019.07.011
With the development of MRI technology, especially the wide application of fast magnetic resonance spectroscopic imaging, fetal 3D volumetric MRI has become an emerging technology for prenatal diagnosis. It is more accurate, more intuitive to observe fetal development, tridimensional structure, mutual relations, together with strong third dimension, large visual field and arbitrary angle, which is gradually applied in various fetal systems in order to make up the deficiency of 2D MRI. In recent years, 3D MRI has been used combined with computer(semi) automatic segmentation technology for volumetric measurement of fetal structures in an attempt to obtain a more detailed image of fetus in a non-invasive way. The developing fetus has also been reconstructed in 3D model, which plays an important role in evaluating normal anatomy, physiological changes and congenital malformations of fetal systems.
