DONG Hai-bo;MA Xiao-jie;CHEN Chuan-feng;LI Ya-di
DOI:
Objective: To explore the cerebral activation of depression patients when performing self-focused attention tasks and the correlation between self-focused attention and depression. Methods: Eight depressive patients and nine healthy volunteers underwent fMRI scan using three self-focused attentional patterns stimulus in a block design, SPM8 software was used for image data processing. Comparative brain activation maps between depression patients and healthy volunteers were carried out. Results: The active areas of depressive patients are more extensive than that of healthy volunteers in three target stimulus conditions. For the depressed patients, the active areas in the “I” target stimulus conditions are more extensive than that of “He” and “*” conditions. Conclusion: Depressive patients may have self-focused attentional bias, self-focused attention might be associated with depression.

DOI:
Objective: To study the clinical value of 11C-MET PET-CT in the diagnosis of recurrent glioma and in planning radiation therapy target. Method: 11C-MET PET-CT examination was used in 22 glioma patients with cranial MRI enhanced scan diagnosed recurrence, pathological diagnosis obtained by craniotomy and biopsy, the three-dimensional conformal radiotherapy target was sketched using the combination of PET-CT images and MR images in 12 cases with pathologically confirmed recurrence. Results: PET-CT imaging of 22 patients with 11C-MET: true positive 16 cases, true negative 5 cases, false positive 1 case and no false negative cases, the sensitivity was 95.5%(21/22), the specificity was 83.3%(5/6), the false-positive rate was 16.7%(1/6), the false-negative rate was 0, Youden index 0.788; 12 patients with histologically confirmed recurrence were given the three-dimensional conformal radiotherapy, target range of 4 cases was consistent with T1WI enhanced region, 2 cases was greater than T1WI enhanced region, four cases was less than T1WI enhanced region, the target range of 2 cases located entirely outside T1WI enhanced region. Conclusion: 11C-MET PET-CT has a high accuracy in the diagnosis of glioma recurrence, can be used in cases of MRI/CT diagnosis of recurrent, but the clinical diagnosis is not yet confirmed, and can obviously optimize radiotherapy planning in patients with glioma recurrence.

CIDAN Wang-jiu;AI Xi-ting;LU Zai-ming
DOI:
Objective: To analyze the MRI and CT features of parotid hemangiomas(PHS) in infants and young children. Methods: MRI(9/21) and CT(12/21) features and clinical data of 21 cases of PHS were analyzed retrospectively, all cases were proved by pathology. Results: In the 21 cases of PHS, 10 were male, and 11 were female. 18 cases(86%) less than 1 year old, 3 cases(14%) were older than 1 year old. Images of all these cases showed a single lesion with sharp edge, the centers of these were located in the superficial lobe of the parotid; 9(43%) lesions involved the deep lobe, 6 lesions were oval(29%) and 15(71%) lobulated. CT findings showed that the lesions were homogeneous in density with CT value of (36.4±5.9) HU; all lesions had no liquefied necrotic area. The lesion was markedly enhanced on contrast enhanced CT (from 36 HU to 147 HU). Nine cases had MRI, FSE T1WI presented isointense signal compared to masseter muscle; FSE T2WI and fat suppression sequences presented a heterogeneous high signal; all lesions presented venous flow void signal; enhanced examination showed significant enhancement. Two cases were misdiagnosed as lymphoma; 1 was misdiagnosed as pleomorphic adenoma; 12 cases were generally diagnosed as benign masses; 6 cases were correctly diagnosed as hemangioma. Conclusion: If a lesion located in the parotid gland with benign characteristics found in infants and protruded out of the surface of the parotid gland when it grew larger and was significantly enhanced on contrast enhanced examination, the most probable diagnosis should be hemangioma.

DOI:
Objective: To study the MSCT features of pulmonary Wegener’s granulomacytosis(WG) and the correlation with serum anti-neutrophil cytoplasmic antibodies which include the cytoplasm(CANCA), perinuclear type(PANCA), anti-proteinase 3 antibodies(PR3-ANCA) and anti-myeloperoxidase antibody(MPO-ANCA). And to assess the value of both methods in the diagnosis of pulmonary WG. Methods: Nine cases of pathologically confirmed pulmonary WG and 9 cases of non-WG patients received MSCT scanning and serum anti-neutrophil cytoplasmic antibodies CANCA, PANCA, PR3-ANCA, MPO-ANCA detection, MSCT features and serum anti-neutrophil cytoplasmic antibodies of WG and non-WG were compared． Results: The CANCA and PR3-ANCA positive rate of WG was significantly higher than that of the non-WG(P<0.05); The PR3-ANCA have the highest sensitivity and specificity in the diagnosis of WG; the PR3-ANCA levels of WG has a significant difference(P<0.05) in the presence or absence of some signs including inflammation, nodules and cavities. Conclusion: Though in the diagnosis of pulmonary WG with MSCT have a certain limitation, some MSCT features and the PR3-ANCA levels have a strong correlation. It can express the pathological state of development of the lesions to some extent.

DOI:
Objective: To assess the left ventricular regional rotation of rabbit in early phase of acute coronary occlusion by speckle tracking imaging(STI), in order to investigate the sensibility of this method to evaluate the regional function of left ventricle. Methods: Forty-six healthy New Zealand rabbits had opened had chest operation to establish acute coronary occlusion model by ligating the anterior branch of the left coronary artery. Dynamic two-dimensional image of parasternal left ventricular long-axis, apical four-chamber and two-chamber view, mitral valve, papillary muscles and apex level in short-axis view were acquired twice pre-operation and 10 minutes post-operation. General parameters such as left ventricular end-diastolic diameter(LVEDD), end-systolic diameter(LVESD), fraction shortening(LVFS), end-diastolic volume(LVEDV), end-systolic volume(LVESV), ejection fraction(LVEF) were measured. Rotation angle of 18 regions in three level of left ventricle were analysed by STI. Results: ①There was no statistical difference between post-operation and pre-operation in LVEDD, LVESD, LVFS, LVEDV, LVESV, LVEF(P>0.05)． ②On mitral valve level rotation angle was the maximum in inferior and posterior-septum, but the smallest in anterior and lateral pre-operation. There was no statistical difference of rotation angle among every region post-operation on mitral valve level, pre-operation and post-operation on papillary muscles and apex level(P>0.05). ③Rotation angle of anterior-septum, posterior-septum, inferior and posterior on mitral valve level were obviously decreased post-operation(P<0.05), and there was no statistical difference of anterior and lateral on mitral valve level, every region on papillary muscles and apex level between post-operation and pre-operation(P>0.05). Conclusion: Assessment of left ventricular regional rotation in early phase of acute coronary occlusion by STI can sensitively reflect the change of regional function of left ventricle.

PAN Fu-zhi;REN Wei-dong;ZHANG Yao;QI Xu;WAN Bo-wei
DOI:
Objective: To evaluate ultrasound findings that are predictive of the need for surgical management in pediatric patients with small bowel intussusception. Methods: A retrospective review of pediatric patients with small bowel intussusception treated from January 2010 to August 2012 was conducted. Patients were divided into surgical and non-surgical groups. Demographic data, ultrasound findings, treatments, and outcomes were collected and analyzed. Results: There were 56 cases of small bowel intussusception in 31 males and 25 females age ranging from 4 months to 9 years; Thirty-nine patients were managed conservatively and 17 patients underwent surgery. The mean length and diameter of the intussusception in the surgical group were 6.53 cm and 2.78 cm respectively, and 3.21 cm and 1.81 cm respectively in the non-surgical group(both, P<0.001). Multivariate logistic regression analysis indicated that diameter and length were independent predictors of surgery. Receiver operating characteristic curve analysis indicated an intussusception diameter≥2.1 cm and length≥4.2 cm were optimal cutoff values for predicting the need for surgery. Conclusions: A diameter≥2.1 cm, and length≥4.2 cm predict the need for surgical management in pediatric patients with small bowel intussusception.

HAO Jin-hua;SUN Xiao-ying;ZHAO Xiao-hua;CAO Yuan-guo;WEI Jin
DOI:
Objective: To study the relationship between nuchal ligament degeneration and cervical degeneration by combined MSCT and ultrasound. Methods: The patient group consisted 65 cases with cervical vertebral diseases, and the control group had 58 healthy individuals. Neutral position MSCT volume scanning were performed in each group. High frequency ultrasound scanning were performed in neutral position and 45° anterial extension position. The morphology, density, minimum cross section area change rate of nuchal ligament were observed and measured. The results and measurement were compared and analyzed. Results: In the patient group, 33.85% of cases had lost the normal triangular shape of the nuchal ligament, 38.46% of cases had funicular twist of the nuchal ligament, 27.69% had cord like calcification of the ligament. Compared to the control group, there were thickening of the funicular and membranous part of the Ⅰ～Ⅳ segment of the nuchal ligament with increased density in the patient group. There were significant differences between the two groups(P＜0.05). In the patient group, the mini-cross sectional area change rate of the funicular part of Ⅰ, Ⅱ, Ⅳ segment of the nuchal ligament decreased and Ⅲ segment increased. There were significant differences between the two groups(P＜0.05). Conclusion: Degenerative changes of the nuchal ligament has close relationship with degeneration of the cervical vertebrae and diseases. Abnormal changes of the morphology, density minimum corss-sectional changes rate as well as calcification of the nuchal ligament are also degenerative appearances of the cervical vertebrae. Familiar with these imaging features is important to the diagnosis and clinical treatment.

409 Optimization of b value in diffusion-weighted MRI for the differential diagnosis of benign and malignant vertebral fractures
ZHANG Lu-lu;LI Song-bai
DOI:
Objective: To explore the optimal b value in diffusion-weighted imaging(DWI) of MRI for differential diagnosis of benign and malignant vertebral fractures. Methods: Thirty-one consecutive patients with vertebral compression fractures underwent sagittal DWI with different b values. The group included 17 patients with 23 benign vertebral fractures due to osteoporosis and/or trauma and 14 patients with 22 malignant vertebral fractures due to malignancy. The quality of the images was analyzed by measurement of the contrast ratio(CR) and the contrast SNR(CNR). Apparent diffusion coefficient(ADC) values were also calculated. The CR, CNR and ADC values in various b value were compared between benign group and malignant groups. Results: The mean CR of the images ranged from 0.71±0.41 at the b value of 300 s/mm2 to 0.27±0.26 at the b value of 800 s/mm2. The mean CNR of the images ranged from 9.03±4.25 at the b value of 300 s/mm2 to 3.42±3.24 at the b value of 800 s/mm2. The CR and CNR of DWI with the b value of 300 s/mm2 were significantly different from that with other b values(P<0.05). The CR values and CNR values between the benign fractures and malignant fractures were not statistically different. The mean ADC values of malignant fractures were significantly lower than those of benign ones on DWI with b values from 300 s/mm2 to 600 s/mm2. Conclusions: When DWI with multiple b values are used to differentiate benign from malignant vertebral compression fractures, smaller b value may be better.

LIU Jie;CHEN Yong;YU Bao-hai;SHI Yun-heng;WU Wen-juan
DOI:
Objective: To analyze the characteristic imaging features and distribution of tumor and tumor-like lesions of the scapula. Methods: From 2007 to 2011, 51 cases of scapular lesions confirmed by pathology were enrolled into this study. The imaging characteristics and location of the lesions were ananlyzed retrospectively. Results: The fifty-one cases of scapular lesions accounted for 2.15% of the whole body bone tumors over the same period, which including 15 types of pathological lesions, 22 cases(43.1%) were benign tumors, 6 cases were tumor-like disorders, 23 cases(45.1%) were malignant tumors. Osteochondroma was the most common benign tumor(n=17, accounting for 77.3% of scapular benign tumors), and followed by chondroma(n=2) which was the second common benign tumor. Eosinophilic granuloma(n=2) and intra-osseous ganglion cyst(n=2) were the two common tumor-like disorders. The most common malignant tumors were metastatic tumor(n=14, 60.9% of the 51 cases). Chondrosarcoma was the second common malignant tumor of the scapula(n=4, 44.4% of the primary malignant scapular tumors). Except one case of chondroblastoma in which the lesion involved the glenoid cavity, all of the other cartilaginous tumors located in the scapular body and bony processes. The type of lesion in the bony process is the same as in the scapular body. The common lesions in the central area of body were malignant tumors. The most common lesions in the glenoid area were metastasis, and the intra-osseous ganglion cyst was the characteristic benign lesion in this area. The common imaging features of malignant scapular tumors were ill defined margin, cortical destruction and soft tissue involvement. But the imaging features except calcification within chondrosarcoma are lack of specificity. The benign lesions of scapula usually showed clear boundary and marginal sclerosis. Conclusion: Scapular tumors or tumor-like lesions are relatively rare. The most common types of tumor are cartilage tumor and metastasis. The location and distribution of different types of lesions in the scapula are similar to those of long bones in some degree.
