Objective: To evaluate the relationship between internal carotid artery stenosis, plaques properties and stroke occurrence in transient ischemic attacks(TIA). Materials and Methods: Conventional CT, CT angiography(CTA) and CT perfusion imaging were performed in 26 patients with clinically diagnosed TIA. The time to peak(TTP), cerebral blood flow(CBF) and cerebral blood volume(CBV) were calculated. The stenosis of carotid artery was also assessed. Results: In 26 cases with TIA, CTA showed 19 cases of internal carotid artery stenosis, mild stenosis in 7 cases(37%), moderate stenosis in 8 cases(42%), severe stenosis in 4 cases(21%). Carotid plaques in 44 places, including 9 mixed plaques, 22 calcified plaques, 7 fibrous plaques, 6 lipid plaques. Old-age incidence was obviously higher than middle-aged group(P<0.05). In 26 cases with TIA, there were 21 normal cases and 5 cases with lacunar infarction, 2 cases had multiple arteries involvement on plain CT scan. Seventeen patients had abnormal CT perfusion and 9 had normal CT perfusion in 26 cases. The TTP of affeted side (11.25±1.94)s compared with that of the contralateral side (8.64±0.96)s was significantly prolonged(t=9.418, P<0.01). The difference of the CBF and CBV was not statistically significant between both sides. Follow-up of 6 months in 3 cases had cerebral infarction. Conclusion: Cerebral apoplexy and internal carotid artery stenosis has close relationship in TIA patients. CT perfusion and CTA can provide valuable diagnostic informations for patients with TIA.

DOI:
Objective: The aim of this study was to evaluate the value of 18F-FDG dual head coincidence imaging and 131I-SPECT/CT in the diagnosis of patients with metastatic papillary thyroid carcinoma(PTC). Methods: Fifty-six patients who had thyroidectomy and radioiodine ablation of residual normal thyroid tissue were included. They all had 18F-FDG dual head coincidence imaging and 3 days after giving 3.7~7.4GBq 131I 131I-SPECT/CT were performed. We had comparative analysis of the two imaging results and the variable parameters between the 18F-FDG dual head coincidence imaging positive group and 18F-FDG dual head coincidence imaging negative group. Results: The sensitivity, specificity, accuracy, positive predictive value and negative predictive value were 84.21%(32/38), 94.44%(17/18), 87.5%(49/56), 96.97%(32/33), 73.91%(17/23). The difference was significant between 131I-SPECT/CT and 18F-FDG dual head coincidence imaging in sensitivity, accuracy, negative predictive value(χ2=16.114, 14.175, 6.285, all P<0.05）. Metastatic size of 18F-FDG dual head coincidence imaging positive group and negative group were (1.83±0.30)cm, (1.29±0.26)cm, respectively, the difference between them was statistically significant(P<0.001). Conclusion: 131I-SPECT/CT was likely to disclose more metastasis than 18F-FDG dual head coincidence imaging in patients with PTC. 18F-FDG dual head coincidence imaging is an important supplement of 131I-SPECT/CT in detecting metastatic PTC, the metastatic size affected the sensitivity of 18F-FDG dual head coincidence imaging.

DOI:
Objective: To analyze the imaging findings of triple-negative breast cancer(TNBC) and to improve the understanding and diagnostic performance of the disease, by comparing it with idiopathic granulomatous mastitis(IGM). Methods: The imaging findings in 63 randomly assigned women with surgically and pathologically confirmed TNBC(n=45) and IGM(n=18) were retrospectively analyzed. All cases underwent a mammographic examination. An ultrasonic examination was performed in 37 cases of TNBC and 18 cases of IGM. MR examination was performed in 33 cases of TNBC and 14 cases of IGM. The mammographic imaging findings included lesion shape, density, margin, calcification, axillary adenopathy and thickening of the skin. The ultrasound imaging findings included shape, margin, size, echo, axillary adenopathy and thickening of the skin. The MR imaging findings included tumor shape, size, margin and internal enhancement, signal intensity within the tumor as well as peripheral signal intensity on T2-weighted, then the type of time-signal intensity curve(TIC) was analyzed. Results: The results of comparing TNBC group with IGM group showed as follows: ①Mammography imaging findings: mass type accounts for 67%(30/45) in TNBC group and 39%(7/18) in IGM group. Smooth margin of the lesion accounts for 60%(18/30) in TNBC group, while 29%(2/7) in IGM group.②Ultrasound imaging findings: mass type accounts for 92%(34/37) in TNBC group and 89%(16/18) in IGM group. Smooth margin of the lesion accounts for 62%(21/34) in TNBC group, while 37%(6/16) in IGM group.③MR imaging findings: mass type accounts for 91%(30/33) in TNBC group and 86%(12/14) in IGM group. Rim enhancement accounts for 67%(20/30) in TNBC group and 75%(9/12) in IGM group. For the rim enhancement mass type, smooth margin of the lesion accounts for 70%(14/20) in TNBC group, while 11%(1/9) in IGM group; peripheral hyperintense pattern on T2-weighted accounts for 85%(17/20) in TNBC group and 21%(2/9) in IGM group. Conclusion: We believe that through careful observation of the lesion site, shape, edge of the tumor mass and peripheral signal intensity on T2-weighted, enhancement pattern and the TIC types, might be useful for the identification of TNBC and IGM.

DOI:
Objective: To explore the image characteristics and regularity of color Doppler echocardiography(CDE) on levoversion deformity. Methods: Fifty-two patients with levoversion deformity were examined by CDE to explore their image characteristics and regularity. All cases with levoversion deformity underwent angiocardiography examination after CDE. Thirty-four cases were proved by surgical operations. Results: Forty-eight cases were diagnosed correctly by the features of CDE imaging. The diagnostic accuracy rate was 92.3%. The CDE characteristics of levoversion were: ①Levoversion can be associated with 8 kinds of complicated congenital heart disease, among which corrected transposition of the great arteries(34.6%) were common, bilocular heart(19.2%), double-inlet ventricle(15.4%), double outlet right ventricle(13.5%), and mitral atresia(11.6%) were less common, tricuspid atresia, complete transposition of the great arteries and persistent truncus arteriosus(1.9% each) were rare. ②Each kind of complicated congenital heart disease combined multiple congenital heart deformity, among which were transposition of the great arteries(98.1%), pulmonary stenosis(88.5%), ventricular septal defect(60.0%), atrial septal defect(38.5%) and patent ductus arteriosus(7.7%). ③With pulmonary stenosis, color Doppler flow image showed obvious signal of colorful mosaic jet through the pulmonary artery. With ventricular septal defect, atrial septal defect and patent ductus arteriosus, color Doppler flow image showed mild colorful flow signal of shunt. ④Despite the diversity of combined congenital heart disease, all cases of levoversion had a common CDE characteristic of atria situs inversus. Conclusions: The image characteristics and regularity of CDE on levoversion deformity were obvious. CDE can be used to correctly diagnose levoversion deformity, only if the operators of CDE have a clear idea of the anatomy of the levoversion. Before examination, reading front view chest X-ray image would be helpful to improve accuracy and efficiency of diagnosis.

LIU Shuai;ZHAO Wei-dong;CHEN Peng;ZHANG Hong-yu;CAI Lin
DOI:
Objective: To investigate the value of whole body DWI(WB-DWI) in differential diagnosis of multiple bone metastases and multiple myeloma. Materials and Methods: Fifty-seven cases with multiple bone tumors and 12 cases normal volunteers underwent WB-DWI. Furthermore, the signal characteristic and ADC values of the thoracic, lumbar vertebrae, and llilac bone were analyzed and measured respectively. In addition, the detection frequency for searching primary tumors in patients with multiple osseous metastases was calculated. Results: Multiple osseous tumors demonstrate abnormal high signals on WB-DWI. The ADC value of multiple osseous metastases were higher than that of multiple myeloma. Meanwhile, the ADC value of multiple myeloma and multiple osseous metastases were markedly higher than that of normal bone. The difference was significant in ADC values between multiple myeloma and multiple osseous metastases(P<0.01). The detection frequency for searching primary tumors in patients with multiple osseous metastases was 74.5%(35/47). Conclusion: Multiple osseous metastases and multiple myeloma can be differentiated by quantitative analysis with ADC value. The WB-DWI can demonstrate primary tumors, which also can help to differentiate multiple osseous metastases and multiple myeloma.
