DOI: 10.12117/jccmi.2018.10.001
Objective: To investigate the effect of pseudo-continuous arterial spin labeling(pCASL) on cerebral blood flow(CBF) in cerebral palsy(CP) children with sympathetic plexus stripping of common carotid artery. Methods: In this study, 50 CP children with sympathetic plexus stripping of common carotid artery and 20 healthy children were selected from October 2015 to March 2017 in our hospital. The pCASL perfusion MRI examination was performed on normal control group and CP children before and after treatment 7 d and 6 months. And Philips pride software was used to analyze the CBF values in bilateral basal ganglia, parietal lobe gray matter, corona radiata white matter. Besides, the improvement of clinical symptoms of CP children after operation were observed. Results: Before operation, CBF value of CP children was significantly lower than that of the control children by pCASL, there was a significant difference between the two groups, P<0.05. But the values of CBF of CP children after surgery for 7 d and 6 months were still lower than those of the control children, with statistical difference, P<0.05. The CBF value of CP children after the operation for 6 months was significantly higher than that before operation and after operation for 7 d, with statistical difference, P<0.05. In addition, the clinical symptoms of CP children such as speech disorders, muscle tone abnormalities, ataxia, strabismus and salivation were improved obviously. Conclusion: The pCASL can be used in the evaluation of CBF in CP children, and the dynamic observation of the CP children with sympathetic plexus stripping of common carotid artery, which would be recommended for the clinical use as an effective choice.

DOI: 10.12117/jccmi.2018.10.002
Objective: To evaluate the diagnostic and prognostic value of three-dimensional arterial spin labeling(3D ASL) in patients with the mild traumatic brain injury(mTBI). Methods: Thirty-five mTBI patients with negative CT and 25 healthy volunteers underwent conventional MRI and 3D ASL examination. After 3 months of brain trauma, the RPQ score of the patients group was used as a prognostic indicator. Results: Of the 35 patients with mTBI, regional hypoperfusion was found in 17 cases. Thirteen cases(RPQ score>14) were positive for post concussion syndrome(PCS). Of the 17 patients with rCBF local hypoperfusion, 11(64.70%) were positive for PCS, and 18 had no significant local hypoperfusion, and only 2(11.11%) were positive for PCS. In patients with mTBI, the probability of PCS in the local hypoperfusion group was significantly higher than that in the non local hypoperfusion group(P<0.01). Conclusion: 3D ASL perfusion imaging can quantitatively detect the decrease of cerebral blood flow in patients with mTBI. It is of great significance to detect and correct the abnormal brain microcirculation and improve the prognosis of the patients.

DOI: 10.12117/jccmi.2018.10.003
Objective: To investigate the value of CT enhancement pattern in differential diagnosis of papillary thyroid microcarcinoma(PTMC) and micronodular goiter(MNG). Methods: The CT data of 267 cases of thyroid nodules with a diameter of 0.5~1.0 cm confirmed by operation and pathology were retrospectively analyzed. Of them, there were 143 cases of 160 PTMC and 124 of 167 MNG. The ratios of CT values(plane scan/enhanced scan, PS/ES) and the difference(ΔCT value) between benign and malignant nodules were calculated respectively, the PS/ES and ΔCT values of benign and malignant nodules were statistically analyzed by t test, and best thresholds of PS/ES and ΔCT to identify PTMC and MNG were determined by ROC curve. Results: Among 160 PTMC and 167 MNG, the PS/ES(t=10.35, df=319.346, P<0.001) and ΔCT values (t=-10.242, df= 322.712, P<0.001) were statistically significant. The area under the ROC curve was 0.799 for PS/ES. When PS/ES was 0.525, the maximum Youden index was 0.520, the sensitivity and specificity were 83.1%(133/160) and 68.9%(115/167), respectively. The ΔCT value under the ROC curve was 0.808. When the ΔCT value was 51.5 HU, the Youden index was the largest (0.514), the sensitivity and specificity were 82.5%(132/160) and 68.9%(115/167), respectively. Meanwhile, the sensitivity and specificity for PTMC with PS/ES≤0.525 and ΔCT value>51.5 HU were 78.1%(125/160) and 78.4%(131/167), respectively. Conclusion: Both PS/ES≤0.525 and ΔCT value>51.5 HU are important parameters in diagnosis of PTMC. The combination of the two can further improve the diagnostic specificity and reduce the misdiagnosis.

Objective: To investigate the predictive value of left ventricular longitudinal strain and plasma brain natriuretic peptide (BNP) concentration on left ventricular systolic function in patients with severe mitral insufficiency during perioperative period. Methods: Thirty mitral insufficiency patients under mitral valve repair or replacement were enrolled for the study. According to postoperative left ventricular ejection fraction(LVEF) greater than or equal 50%(group A) to or less than 50%(group B), they were divided into two groups. Left ventricular global longitudinal strain(GLS) and serum BNP were measured before operation and on the postoperative 7th day. Results were compared and analyzed. Results: There was no significant difference in LVEF between the two groups before operation. The absolute value of GLS on the postoperative 7th day was lower than that in the preoperative level in both two groups. The absolute value of GLS in group B was lower than that in group A, but the plasma BNP concentration in group B was higher than that in group A(P<0.05). The postoperative LVEF was negatively correlated with GLS, positive correlation with postoperative BNP(P<0.05). GLS was the independent predictors of postoperative LVEF reduction. Conclusion: GLS along with BNP were sensitive paramerers of left ventricular systolic function for evaluation the patients with mitral insufficiency during perioperative period.

Objective: To observe and analyze the bladder neck in patients with different degrees of stress urinary incontinence(SUI) through transperineal ultrasound, and to find the best diagnostic threshold of SUI. Methods: A total of 255 cases of SUI(111 cases of mild SUI group, 96 moderate SUI group, 48 severe SUI group) were selected from September 2014 to February 2016 in our hospital, 266 cases in the same period for healthy patients as normal control group, and the transperineal ultrasonography was performed on the selected subjects, recorded the bladder neck back shift(ΔDx), the downward distance(ΔDy), the bladder neck movement(Mu) and the bladder neck rotation angle(θ) after the forced breathing maneuver. The ultrasound data were analyzed and compared. According to the results of multivariate Logistic regression analysis, the ROC curve of θ were constructed, and the diagnostic threshold of SUI was preliminarily determined. Results: The comparison among four groups, the values of Mu, θ in the normal control group, mild SUI group, moderate SUI group, severe SUI group increased in turn, ΔDy of SUI patients were higher than those of the normal control group, ΔDy of moderate SUI group and severe SUI group were higher than those of the mild SUI group, ΔDx of moderate and severe SUI group were higher than those of normal and mild SUI group, the differences were statistically significant(P<0.05). Multivariate Logistic regression analysis showed that age, high BMI, ΔDy, Mu, and θ were all in the regression equation, and the regression coefficient of θ was the highest. When θ was 21.5°, the sensitivity and specificity of the diagnosis of SUI were higher. Conclusion: With the increase of the degree of SUI, the migration of the female bladder neck in the pelvic cavity increases significantly, the age and high BMI are all the risk factors for the occurrence of SUI, ΔDy, Mu, θ can be used as the ultrasonic diagnostic indexes of SUI, and θ can be used as the best diagnostic index, and the θ value of 21.5° can be used as the best diagnostic threshold.

DOI: 10.12117/jccmi.2018.10.007
 Objective: To detect the value of dual-phase contrast enhancement by 320-slice CT in the differential diagnosis of common renal cell carcinoma(RCC) subtypes. Methods: The clinical data of 224 cases of RCC confirmed by pathology were retrospectively analyzed, including 196 cases of clear cell RCC, 14 cases of papillary RCC and 14 cases of chromophobe RCC. The morphology, calcification and strengthening methods of the tumor were analyzed. T test was used to compare the enhancement degree of RCC in different pathological subtypes, the CT ratio between the lesion and the abdominal aorta, and the area under the ROC curve, sensitivity and specificity were calculated. Results: Clear cell RCC commonly manifested heterogeneous, and papillary RCC were homogeneous enhancement, while chromophobe RCC were homogeneous enhancement and solid-based heterogeneous enhancement. Therefore, the possibility of clear cell RCC was suggested when the focus was cystic or cystic and solid mixture inhomogeneous enhancement(χ2=4.286, P<0.05). The enhancement degree of clear cell RCC in cortical and parenchymal phase was significantly higher than that of chromophobe RCC and papillary RCC(P<0.01). The sensitivity and specificity of single-phase contrast enhancement for discriminating clear cell RCC from papillary RCC were 87.76%～92.35%, 78.57%～85.71%, the sensitivity and specificity for discriminating clear cell RCC from chromophobe RCC were 74.49%～87.73%, 85.71%～92.86%, the sensitivity and specificity of dual-phase contrast enhancement in the differential diagnosis of clear cell RCC, papillary RCC and chromophobe RCC were 88.27%～91.33%, 85.71%～92.82%.

Objective: To investigate the imaging features of spine giant cell tumor(GCT) and solitary plasmacytoma of bone(SPB), so as to improve the understanding of the two kinds of tumors. Methods: The CT and MRI findings of 19 cases of GCT and 12 cases of SPB confirmed by pathology were compared and analyzed, and the differences of imaging findings were summarized. Results: In 19 cases of GCT, 68.4% were aged between 20 and 40, 11 cases were located in the sacral vertebra, 5 in the thoracic vertebra, 2 in lumbar vertebra and 1 in cervical vertebra. Thirteen cases were swelling and osteolytic bone destruction, 6 cases of compression fractures with severe compression, the residual bone crest slender and 68.75% of the soft tissue masses occurred around the centrum. Because of easy occurrence of bleeding and necrosis, MRI signals were often uneven. In 12 cases of SPB, 58% were aged between 40 and 60, 10 cases occurred in the thoracic vertebra, 1 in cervical vertebra and 1 in lumbar vertebra. Ten cases were osteolytic bone destruction, 7 cases of mild and moderate compression in 10 cases of compression fracture, the residual bone crest was relatively thick. 83.33% of the soft tissue masses were located in the spinal canal, and MRI signals were often homogeneous due to rare cystic degeneration and bleeding. Conclusion: The bone destruction form, the degree of compression fracture, the location of soft tissue masses, the shape of residual bone crest and cystic degeneration and bleeding signal are helpful for the differential diagnosis of GCT and SPB.
