HU Li-juan, LIAO Kai-bing
Objective: To study the 3.0T multivoxel proton magnetic spectroscopy(1H-MRS) findings in brain glioma and to investigate the correlation between Cho/Cr ratio and expression of Ki-67. Methods: Fifty-seven patients of brain gliomas were studied, including 28 cases of low-grade group(grade Ⅰ~Ⅱ), 29 cases of high-grade group(grade Ⅲ~Ⅳ). All of them underwent 3.0T 1H-MRS examination before operation. The Cho/Cr ratios were detected. We analyzed the correlation between Cho/Cr ratio and pathological grade of gliomas. Ki-67 immunohistochemical staining and Ki-67 labeling index(Ki-67LI) were measured after operation. We also analyzed the correlation between Ki-67LI and the pathological grade, the Cho/Cr ratio of gliomas. Results: ①Significant differences were found in the ratios of Cho/Cr between low grade gliomas and high grade gliomas(P<0.001). The ratio of Cho/Cr was positively correlated with the tumor grade(r=0.616, P<0.001). The area under the curve(AUC) of Cho/Cr was 0.856. The threshold value of Cho/Cr ratio for differential diagnosis high grade and low grade brain gliomas was 2.44, the sensitivity was 79.3%, the specificity was 82.1%. ②Ki-67LI of low grade glioma was (3.41±2.35)%, Ki-67LI of high grade glioma was (19.78±11.45)%, the difference was statistically significant(Z=-0.617, P<0.001). The Ki-67LI was positively correlated with the tumor grade and the Cho/Cr ratio(r=0.804, P<0.001). Conclusion: The Cho/Cr ratios of gliomas are correlated with the expression of Ki-67. It may be a useful image index, which can evaluate the proliferation activity and malignancy degree of glioma, without invasion. And it may be helpful in the clinical treatment and prognosis assessment.

ZHU Jie1, ZHANG Bei2, SONG Bin1, WEI Ran1, WENG Ying-feng1
Objective: To explore the value of 128-slice spiral CT low doses whole-brain CT perfusion imaging(CTP) with 70 kV, 100 mAs in evaluating the treatment response of acute cerebral infarction. Methods: Conventional cerebral CT scanning and the low dose whole-brain CTP were performed on 23 patients with acute cerebral infarction within 24 hours. Seven patients underwent emergency intravenous thrombolysis treatment, and 16 patients underwent routine drug treatment. All patients were reexamined by the same schedule after 7~10 days’ treatment, the cerebral perfusion parameters of central and edge region, including the relative cerebral blood flow(rCBF), relative cerebral blood volume(rCBV), relative time to peak(rTTP) and relative mean transit time(rMTT), were compared before and after treatment. Results: Abnormal low perfusion changes corresponding to clinical symptoms were found in all 23 patients by emergency low doses whole-brain CTP. After 7~10 days’ treatment, the low dose whole-brain CTP showed that the ranges of low perfusion in 21 patients were narrowed, and 2 cases were expanded after treatment. After intravenous thrombolysis treatment, there was statistically significant difference in rCBF of the ischemic central region before and after treatment(P<0.05), and there was no statistically significant difference in rCBV(P>0.05). After routine drug treatment, there was no statistically significant difference in rCBF and rCBV of the ischemic central region(P>0.05). After both intravenous thrombolysis treatment and routine drug treatment, statistically significant differences were found in rCBF, rTTP and rMTT of the ischemic marginal region(P<0.05). No significant difference was detected in rCBV of the ischemic marginal region(P>0.05). Conclusion: The low doses whole-brain CTP could significantly reduce the effective radiation dose, meanwhile, it could not only diagnose acute cerebral infarction but also observe the cerebral hemodynamic changes before and after treatment, combining with routine CT scan and CTA, which provide comprehensive imaging basis for evaluating the therapeutic effect of acute cerebral infarction.

WANG Ya-ting, ZHU Yan, GUO Li-li, SHI Yu-zhen, CHEN Wei, BAI Gen-ji
Objective: To determine whether change of apparent diffusion coefficient(ADC) values could predict early response to chemotherapy in breast cancer liver metastases(BCLM). Methods: We retrospectively studied 42 patients with BCLMs(86 lesions) who had undergone conventional MRI and DWI at 3 days before chemotherapy and 1 week, 2 weeks, 4 weeks after chemotherapy. Selected patients were divided into responders(R) and non-responders(NR). The grouping reference was based on MRI according to response evaluation criteria in solid tumors(RECIST). Results: Eighty-six metastases were classified as 40 R and 46 NR. The difference in maximum tumor diameter of R group between pre-chemotherapy and 4 weeks after chemotherapy was significant(P<0.05). Pretreatment mean ADC((1.06±0.07)×10-3 mm2/s) of R group was significantly lower than that of NR group((1.22±0.14)×10-3 mm2/s)(P<0.05). After 1 week of chemotherapy, the mean ADC of R group increased slightly and the mean ADC of NR group decreased slightly, with no statistical significance. After 2 weeks and 4 weeks of chemotherapy, the mean ADC of R group increased significantly but not in NR group. The results of ROC curve showed that areas of under the curve were 0.846, pretreatment ADC of 1.11×10-3 mm2/s concluded BCLMs to chemotherapy ineffective sensitivity and specificity value were 78.3% and 87.5%, respectively. Conclusion: The pretreatment and 2 weeks after treatment ADC value may be helpful to predict early response to chemotherapy in BCLM.

There was no statistical difference of diagnostic accuracy between SPECT/CT and CT for spondylolysis(P>0.05), but both of them were higher than SPECT(P<0.05). For unstable spondylolysis, sensitivity and accuracy rate of SPECT/CT was higher than SPECT and CT(P<0.05). Conclusion: 99mTc-MDP SPECT/CT bone imaging has additional value of spondylolysis, especially the unstable spondylolysis diagnosis.

220 The clinical application of intracavitary contrast-enhanced ultrasound
WANG Yang, TANG Shao-shan, DONG Tian-jiao
With the development of contrast-enhanced ultrasound, there has been exponentially increasing interest in the clinical applications of intracavitary contrast-enhanced ultrasound and new fields have been investigated in recent years. In clinical practice, ultrasound contrast agents can be used for contrast imaging of physiological body cavities and non-physiological body cavities. However, the currently available ultrasound contrast agents are not approved for this purpose. Prospective studies in sufficiently large patient numbers are required to support the usefulness of intracavitary contrast-enhanced ultrasound. In the review, the development and prospect of clinical application of intracavitary contrast-enhanced ultrasound are generally introduced.
