CHEN Wei-nan, ZHANG Chun-mei, ZHANG Juan
DOI: DOI:10.12117/jccmi.2019.04.001
Objective: To investigate the correlation between internal jugular vein spontaneous echo contrast(IJVSEC) and stroke. Methods: One hundred patients with ischemic stroke were selected as stroke group and 50 normal persons without stroke history were selected as control group. All subjects underwent routine ultrasound examination and stroke risk factor analysis. Then, the severity of stroke was evaluated by National Institute of Health Stroke Scale(NIHSS). According to the trial of org 10 172 in acute stroke treatment(TOAST), stroke patients were divided into five subtypes. The relationship between different etiological types and related risk factors, laboratory indicators and ultrasound detection indicators was analyzed, and all data were analyzed statistically. Results: The fibrinogen, hemoglobin, D2 polymers, intimal-medial thickness(IMT), NIHSS score, plaque integral and spontaneous echo contrast(SEC) score in stroke group were significantly higher than those in control group(P<0.001), but there was no significant difference between the two groups in MV of bilateral internal jugular vein(P>0.05). Plaque integral and IMT were different in different subtypes of stroke patients. There was no significant difference in SEC score and MV of bilateral internal jugular vein between atherosclerotic stroke group and other stroke types group(P>0.05). SEC score was positively correlated with fibrinogen, hemoglobin, D2 polymers, NIHSS score(r=0.274, P<0.001; r=0.330, P<0.001; r=0.421, P<0.001; r=0.731, P<0.001), not correlated with plaque integral and IMT(r=0.049, P=0.547; r=0.025, P=0.759), and SEC score was positively correlated with jugular venous reflux(JVR)(r=0.409, P＜0.001). Conclusions: IJVSEC is more likely to occur in patients with ischemic stroke, and there is a close correlation between the two, and the severity of IJVSEC is correlated with the severity of stroke. IJVSEC phenomena in stroke patients may be formed through other mechanisms besides atherosclerosis, and whether IJVSEC can be used as a marker or therapeutic index of stroke needs further study.

DOI: DOI:10.12117/jccmi.2019.04.002
Objective: To investigate the value of division of sella region and imaging features(CT, MRI) in the differential diagnosis of benign and malignant sellar space-occupying lesions. Methods: A retrospective analysis was made of 151 cases of sellar space-occupying lesions confirmed by surgery and pathology. The imaging features of lesions in the intrasellar, suprasellar, parasellar and mixed areas were analyzed statistically. The value of division of sella region and imaging features in the differential diagnosis of the sellar space-occupying lesions was discussed. Results: The partition value: Among 151 cases of sellar lesions, benign lesions(75%, 113/151) were significantly higher than malignant lesions(25%, 38/151), 22, 25, 42 and 62 cases in intrasellar, suprasellar, parasellar and mix regions respectively. There were significant differences in the distribution of benign and malignant lesions in sellar region(χ2=6.670, P=0.036<0.05), the highest proportion of intrasellar, suprasellar and parasellar were pituitary adenoma, craniopharyngioma and meningioma, the difference of lesions involving single and mixed region was statistically significant(χ2=10.246, P=0.001<0.01), lesions involving only a single zone(66%, 75/113) were significantly more than the mixed zone(34%, 38/113) in 113 benign cases, the lesions involving the mixed area(63%, 24/38) were significantly more than those in the single region(37%, 14/38) in 38 cases of malignant lesions. The imaging features: benign and malignant lesions had statistical significance differences in location, size, shape, boundary and bone destruction. There was no significant differences in age, sex, tumor characteristic, calcification, presence of pituitary, internal carotid artery and cavernous sinus invasion or wrapping. Conclusion: The distribution and imaging features of the sellar region space-occupying lesions have certain characteristics, which is of high value in the differential diagnosis of the sellar region space-occupying lesions.

ZHOU Qun, ZHU You-ling, MU Yan-fang, TANG Min, ZHAI Deng-yue
DOI: DOI:10.12117/jccmi.2019.04.003
Objective: To investigate the association between anterior circulation artery(intracranial carotid artery or middle cerebral artery) stenosis and lacune or lacunar infarction in elderly patients. Methods: The imaging data of 74 elderly patients with intracranial artery atherosclerosis and ischemic cerebral infarction in our hospital from May 2016 to August 2017 were retrospectively analyzed. All patients underwent brain MRI or CT plain scan, as well as magnetic resonance angiography(MRA). The association between anterior circulation artery stenosis, vascular stenosis distribution, vascular stenosis degree and lacune or lacunar infarction was analyzed. Results: There were 49 cases of lacune or lacunar infarction in 63 elderly patients with anterior cerebral circulation artery stenosis(49/74, 66.2%), and only 4 cases of lacune or lacunar infarction in 11 patients without anterior circulation artery stenosis(4/74, 5.4%). There was a correlation between the anterior cerebral circulation artery stenosis and the occurrence of lacune or lacunar infarction(χ2=5.996, P=0.014). There were 16 cases of lacune or lacunar infarction in 25 patients with unilateral anterior circulation artery stenosis(16/63, 25.4%), and 33 cases of lacune or lacunar infarction in 38 patients with bilateral anterior circulation artery stenosis(33/63, 52.4%). There was a correlation between the vascular stenosis distribution and lacune or lacunar infarction occurrence(χ2=4.552, P=0.033). There was no significant difference between the different degrees of anterior circulation artery stenosis(χ2=2.550, P=0.466). Conclusions: The correlation between intracranial carotid artery or middle cerebral artery stenosis and lacunar infarction or lacune in elderly patients may exist. Risk for lacunar infarction or lacune is higher in patients with bilateral artery stenosis than in patients with unilateral artery stenosis.

MA Ke-ran, CHENG Jing-liang, ZHANG Xiao-nan, WANG Fei-fei, SONG Cheng-ru
DOI: DOI:10.12117/jccmi.2019.04.004
Objective: To evaluate the value of diffusion weighted imaging(DWI) and dynamic contrast enhanced MR imaging combined with conventional MR imaging(MRI) in the diagnosis of Kimura disease(KD). Methods: The clinical data and MRI findings of 7 patients with KD located in parotid glands proven by histopathologic examination were retrospectively analyzed. Results: Two patients had bilateral onset and 5 patients had unilateral onset. According to the shape of the lesion and the involved tissues, they were divided into 3 types: type Ⅰ(3 cases): subcutaneous lesions diffuse infiltration to the parotid gland; type Ⅱ(3 cases): intraparotid lymphadenopathies; type Ⅲ(1 case): mixed mode. On plain scan, type Ⅰ showed equal signal on T1WI, mixed slightly high signal on T2WI; type Ⅱ showed equal signal on T1WI, slightly high signal on T2WI in 2 cases, equal signal in 1 case; type Ⅲ showed slightly high signal on T1WI, mixed slightly high signal on T2WI. Dynamic enhanced MRI scan showed progressive enhancement of subcutaneous infiltration to parotid gland lesions, and early enhancement of reactive lymph nodes. The ADC value of normal parotid gland was (0.89±0.06)×10-3 mm2/s, that of subcutaneous infiltration to parotid gland lesions was (1.24±0.10)×10-3 mm2/s, and that of reactive lymph nodes was (0.62±0.06)×10-3 mm2/s. Conclusions: The ADC values of subcutaneous infiltration to parotid lesions were higher than those of normal parotid glands, and the ADC values of reactive lymph node lesions were lower than those of normal parotid glands. On dynamic enhanced scan, infiltrative parotid gland lesions showed progressive enhancement, and the parotid gland lymph nodes and reactive lymph nodes showed early enhancement. These features can be used as characteristic MR manifestations of KD, combined with its clinical manifestations and laboratory examinations, can highly suggest the diagnosis of KD.

246 The clinical value of MSCT in evaluating the types of superior attachment of uncinate process and drainage pathways
CHE Zi-gang, JI Hong-bo, ZOU Cai-yun, XU Bo-lin, YU Zhen-kun, CHU Cheng-feng
DOI: DOI:10.12117/jccmi.2019.04.005
Objective: To analyze the anatomic variations of superior attachment of uncinate process(SAUP) and drainage pathway in patients with chronic sinusitis by MSCT, and to explore the influence on the frontal sinusitis. Methods: Two hundred and twenty-two sides of 111 patients with sinusitis who were candidates for endoscopic sinus surgery and underwent MSCT scanning were collected. The incidence of various types of SAUP, and the correlation between SAUP and internal and external drainage of uncinate process were determined by MSCT. The difference of frontal sinusitis between internal and external drainage groups was analyzed. Results: Among 222 SAUP types, the most common types of SAUP were type Ⅰ(55%), type Ⅳ(19.8%) and type Ⅴ(12.6%). In the evaluation of frontal sinusitis, 88(39.6%) had frontal sinusitis, 57 internal drainage(46.7%) and external drainage 31(31.0%). In patients with chronic sinusitis, the frontal sinusitis was more common in the internal drainage channels of SAUP than in the external drainage(46.7% vs 31.0%, P＜0.05). Conclusions: Before nasal endoscopic surgery, we need to clarify the anatomical variation of SAUP, and the changes in the location of the outflow tract of frontal sinus caused by SAUP typing affect the incidence of the frontal sinusitis. In patients with chronic sinusitis, frontal sinusitis is more likely to occur when the frontal sinus drainage area is internal drainage than external drainage.

LIANG Li-ping, REN Hai-bo, ZHENG Yan-fen, WU Cai-hong
DOI: DOI:10.12117/jccmi.2019.04.007
Objective: To explore the value of CEUS combined with quantitative analysis in the diagnosis of papillary thyroid microcarcinoma(PTMC). Methods: The CEUS features of 63 solid thyroid nodules(diameter≤10 mm) were retrospectively analyzed. The peak intensity(PI), the rise time(RT), the mean transit time(MTT), the area under the curve(AUC), the time from peak to one half(TPH), the time to peak(TTP), the wash in slope(WS) of nodules were quantitatively analyzed by QLAB software, all nodules were confirmed by surgery and pathology. Results: There was a difference between PTMC and benign small thyroid nodules in enhancement patterns(χ2=33.542, P=0.000). The sensitivity and specificity of early hypo-enhancement or hypo-enhancemen in the diagnosis of PTMC were 82.82% and 79.40% respectively. PI in PTMC was lower than that in tissues surrounding thyroid malignant nodules, benign small nodules of thyroid and tissues surrounding benign small nodules, and the difference was statistically significant(P<0.05). The PI of thyroid benign nodules was lower than that of tissues surrounding the benign nodules, and the difference was statistically significant(P<0.05). The AUC, TTP and WS of PTMC were lower than those of tissues surrounding the benign nodules(P<0.05). There was no significant difference in other groups(P>0.05). The sensitivity and specificity of PI in the diagnosis of PTMC were 86.21% and 88.23% respectively. Conclusion: The main perfusion mode of PTMC was early hypo- or hypo-enhancement. PI is the most valuable quantitative parameter of ROI, which can be used as an important reference index for differentiating benign and malignant thyroid nodules. Quantitative parameters such as RT, MTT, AUC, TPH, TTP and WS have little value in differentiating benign and malignant thyroid nodules.

ZHOU Han-xiao, WANG Hong-qiao
DOI: DOI:10.12117/jccmi.2019.04.008
Objective: To explore the ultrasonographic, molybdenum target mammography and clinicopathological features of the lesions with invasive carcinoma which were diagnosed as ductal carcinoma in situ(DCIS) by preoperative core needle biopsy, so as to evaluate the possibility of invasive components in DCIS before operation, and to help better formulate the surgical and therapeutic plan of DCIS. Methods: Seventy-eight lesions diagnosed as DCIS by preoperative core needle biopsy and resected by surgery were retrospectively analyzed. According to the pathological results after operation, they were divided into two groups(DCIS group and DCIS-Ⅰ group) for descriptive statistics and regression analysis. Results: Of the 78 lesions, 45(57.6%) were confirmed as DCIS and 33(37.9%) were found to have invasive components. Ki-67 overexpression(OR=2.870, 95%CI=1.065~7.730), EGFR positive(OR=4.833, 95%CI=1.083~21.561), ultrasound-detected microcalcification (OR=4.533, 95%CI=1.627~12.633) were correlated with predicting invasive components in DCIS, ultrasound-detected microcalcification(OR=4.746, 95%CI=1.263~17.828) was the most relevant factor in predicting invasive components in DCIS. Conclusion: For the lesions diagnosed as DCIS by preoperative core needle biopsy, if there are high expression of Ki-67, positive EGFR and microcalcification in ultrasound, we should be alert to the high risk of invasive components in DCIS.

DOI: DOI:10.12117/jccmi.2019.04.013
Objective: To compare the diagnostic values of bedside ultrasound and mobile digital radiography(DR) in neonatal intensive care unit(NICU) for neonatal respiratory distress syndrome(NRDS) and wet lung, and for necrotizing enterocolitis(NEC). Methods: The newborns in NICU in our hospital from January 2015 to June 2017 were analyzed. There were 80 cases of newborns with dyspnea within 24 hours after birth. The diagnostic values of bedside ultrasound and mobile DR in NRDS and wet lung were analyzed respectively. During the same period, 67 cases of newborns with NEC were clinically diagnosed. The imaging features detection rates of NEC by bedside ultrasound and mobile DR were compared. Results: The diagnostic accordance rates of both bedside ultrasound and mobile DR in the diagnosis of NRDS were high(93.75% and 100%). However, the diagnostic accordance rate of bedside ultrasound in the diagnosis of wet lung was higher than that of mobile DR(95.35% and 51.16%), with significant difference(P<0.05). Compared with mobile DR, bedside ultrasound has higher detection rates of intestinal wall pneumatosis, portal vein pneumatosis, intestinal dilatation/intestinal obstruction, perforation signs, peritoneal effusion, immature intestinal development, and the difference was statistically significant(P<0.05). Conclusion: The application of bedside ultrasound in NICU is safer and noninvasive than that of mobile DR, and has higher differential diagnostic value for wet lung. The detection rate of various imaging features of neonatal NEC is higher, which is of great significance in guiding clinical diagnosis and treatment, and is worth popularizing.
