GAO Bo;LV Cui;LIU Feng-li;YU Guo-hua;BA Mao-wen
DOI:
Objective: To investigate the dynamic changes of hypertensive encephalopathy in animal models by perfusion-weighted imaging(PWI). Methods: Twenty adult New Zealand white rabbits were randomly divided into control group(group A) and study group(group B), 10 cases in each group. A modified Gloidblatt 2K1C were used in rabbits to establish chronic hypertension model for control group, and intramuscular injection of Metaraminol Bitartrate to induce acute hypertension in the study group. Routine MRI scanning and PWI of brain were performed in rabbit models on the 3.0T MRI scanner. The values of CBV, CBF and MTT were calculated in selected region of interest(ROI) at workstation, and were compared among anterior, middle and posterior brain regions. Results: The changes of CBF were most marked in posterior brain regions. The CBV, CBF increased after injection of Metaraminol Bitartrate and reached the peak on the ninth day, later than MAP which reached the peak on the sixth day, and then decreased to a basically normal level after drug withdrawal for one week. The change of MTT was not significant. Conclusions: During the course of hypertensive encephalopathy, the level of rCBF first increases and then declines, the peak of which is later than those of MAP.

DOI:
Objective: To evaluate the atrophy pattern of subcortical gray matter structures in patients with mild Alzheimer’s disease(AD) by using an automatic segmentation tool. These structures include hippocampi, amygdalae, accumbens, caudates, putamen, pallidum, thalami. Methods: Twenty-nine cases of mild AD and 30 normal aging volunteers as control subjects were scanned with 3D FSPGRIR sequence using 1.5T MR system． The subcortical gray matter structures were segmented using FIRST tool in FSL. The mean values of each structure’s relative volume(gray matter volume/intracranial volume×100) were compared with 2-sample t test. The correlation between the relative volume of each structure and MMSE scores were evaluated using partial correlation analysis. Binary logistic regression analysis and ROC curve were applied to assess the diagnostic significance of the relative volume of each structure. Results: Compared with normal control group, the relative volume of left hippocampus, right amygdala, bilateral thalami, right caudate, left putamen and bilateral pallidum in mild AD group was significantly smaller than that in the control group(P<0.05). The relative volume of left hippocampus, right amygdala, left thalamus and left putamen was correlated with MMSE scores. It was the relative volume of left hippocampus that entered the final model of binary logistic regression analysis. The accuracy was 86.3%. The area under the curve of ROC curve was 0.897. In the cut-off point, i.e. maximal value of Yuden index, the sensitivity was 83.3% and the specificity was 96.3%. Conclusion: In addition to hippocampus, volumetric atrophy was found in other subcortical gray matter structures in mild AD. The atrophy of right amygdala, left putamen and left thalamus may take part in the pathological mechanism of cognitive impairment in AD patients. Among these structures, hippocampus is of the most diagnostic significance.

DOI:
Objective: To evaluate the application value of 18F-FDG PET/CT combined with HRCT in diagnosing pneumonia type of bronchioloalveolar carcinoma(PTBAC). Materials and Methods: The 18F-FDG PET/CT images of 26 cases with pathologically confirmed PTBAC were studied. Fifteen of the 26 cases were followed up after 0~3 days by HRCT study. The diagnostic accuracy rate of 18F-FDG PET/CT combined with HRCT were analyzed. Results: According to 18F-FDG PET/CT imaging, definite diagnosis of malignant was made in 9 cases, no exclusion of malignancies in 13 cases, and definite diagnosis of pulmonary inflammation in 4 cases. The diagnostic accuracy rate of 18F-FDG PET/CT imaging was 34.6%. The misdiagnosis rate of 18F-FDG PET/CT was higher. Associating 18F-FDG PET/CT with HRCT, 13 of 15 cases were diagnosed as malignant tumors. Pulmonary inflammation was diagnosed firstly in 1 case by PET/CT, and then definite diagnosis of malignancy was confirmed by HRCT. In addition, the other one case of malignant tumor was analyzed as pulmonary inflammation by PET/CT and HRCT. However, 18F-FDG PET/CT displayed metastasis during the delay scanning, which was approved by pathology. Based on 18F-FDG PET/CT and HRCT results, 15 cases were diagnosed correctly. Conclusion: PTBAC displays a variety of characteristics in 18F-FDG PET/CT and HRCT. Combining 18F-FDG PET/CT with HRCT is reasonable and practicable for PTBAC diagnosis, which may be due to the synergistic effect on diagnosing PTBAC and can greatly improve the diagnostic accuracy.

DOI:
Objective: To observe the changes of parameters in perfusion CT before and after chemotherapy for patients with lung cancer and its relationship with the efficacy of treatment. Methods: Twenty-five patients were enrolled into the study who were pathologically diagnosed as lung cancer and would undergo conventional chemotherapy for lung cancer. According to RECIST criteria, the patients were divided into remission group and no-remission group. Each patient underwent two perfusion CT scans respectively within a week before and about 90～100 days after chemotherapy. The relationship of parameters changes before and after earlier chemotherapy and the efficacy of chemotherapy was studied. Results: Among the 25 cases, 15 cases had remission and the other 10 cases without remission. For all the 25 patients, the changes of tumor size in the two groups were not significant before and after chemotherapy(with an average interval of 21 days), but the changes of BV and PBV was statistically significant(in the remission group, BV and PBV before and after treatment were (71.0±20.4) mL/1 000 mL, (49.8±31.4) mL/1 000 mL; (73.1±34.1) mL/1 000 mL, (45.2±19.0) mL/1 000 mL; t values of 2.558 and 3.325; P values of 0.023 and 0.005, and the two parameters showed a downward trend. In the group without remission, BV and PBV before and after treatment were (50.4±61.0) mL/1 000 mL, (120.5±15.7) mL/1 000 mL; (38.0±9.3) mL/1 000 mL, (62.0±38.3) mL/1 000 mL; t value of -3.062, -2.471; P value 0.016, 0.036, upward trend). The relativity of the remission rate and the parameters of BV or PBV group χ2 test revealed: regardless of whether the parameter values increased or decreased, the changes of BV and efficacy of chemotherapy were not statistically significant. The changes of PBV correlated well with the effects of chemotherapy. The remission rate of group with reduced PBV was higher than that of the elevated one. Conclusion: No obvious change of size is observed between the lesions before and after chemotherapy in early stage. The changes of the perfusion CT parameters in the early stage after chemotherapy have potential application in predicting the efficacy of chemotherapy in the treatment for lung cancer.

DOI:
Objective: To test whether the diagnostic indicators and criteria in the guidelines for the echocardiographic assessment of the right heart in adults by American Society of Echocardiography in 2010(guidelines) is adaptable to native people. Methods: 210 patients presenting with signs and symptoms of cardiopulmonary disease in patient group and 105 healthy individuals in control group accepted right heart assessment following the guidelines. The student’s t test was used to compare the mean value difference. The ROC curve was used to evaluate the indicators value. Results: All indicators in the patient group were statistically different to those in the control group. The thresholds for diagnosis of right heart failure recommended by the guidelines were of high specificity but poor sensitivity. Conclusions: The guidelines are valuable, and should be incorporated into the clinical material to diagnose right heart failure.

LI Jian-sheng;WANG Dan-feng;LIU Kai;ZHANG Xue-lin
DOI:
Objective: To investigate the CT features and pathology of gastric schwanomas. Methods: The CT imaging of 10 cases of gastric schwanomas proven by surgery and pathology were retrospectively analyzed and correlated with pathology. Results: All of the 10 cases had solitary tumor in stomach, with 6 in the body, 2 in the antrum and 2 in the bottom. All the lesions varied in size, but mainly less than 3 cm. Most of the lesions were of homogeneous iso-density or slightly low density. One case had slightly inhomogeneous attenuation, without any necrosis or cysts. Two cases had ulcer surface. After enhancement, all of the leisons had moderate enhancement in venous phase. Conclusion: CT features of gastric schwanomas had some characteristics and are helpful for the characterization and location of the tumor as well as assessing the relationship of the tumor and surrounding structures. Nevertheless, the concrete diagnosis needs pathology.

718 The diagnostic value of fluid-fluid levels in distinguishing between benign and malignant bone lesions using CT/MR
CHENG Xiao-guang;SU Yong-bin;XU Li
DOI:
Objective: To analyze the diagnostic value of fluid-fluid levels in distinguishing benign and malignant bone lesions using CT/MR. Methods: Sixty-six cases of primary bone lesions proven by pathology were reviewed, among which 12 cases were examined by CT, 51 cases were examined by CT and MR, and the other 3 cases were examined by MR. Fluid-fluid levels(FFLs) were identified in all of the cases. The proportion of the lesion occupied by FFLs was estimated as <1/3, 1/3～<2/3, 2/3～<100% and 100%. The proportion was correlated with the pathological diagnosis and confirmed by double blind method. Results: Pathology revealed 58 benign bone lesions and 8 malignant bone lesions. When the degree of FFLs was <1/3, malignant lesions were relatively common(3/8, 37.5%), and all of which were osteosarcoma. With the increasing of FFLs degree, benign lesion became more frequent. When the degree was >2/3, 93.6% of lesions were benign, most of which were giant cell tumors with aneurysmal bone cysts or primary aneurysmal bone cysts. When the lesions were entire FFls, all of them were benign. Conclusions: More proportion of FFLs in primary bone lesion suggests more possibility of benign bone tumor.
