Objective: To describe the MRI features of the tumor-mimicking primary angiitis of the central nervous system(PACNS) and to discuss MR diagnostic value of the tumor-mimicking PACNS. Materials and Methods: Eight patients with biopsy-proven PACNS mimicking brain tumor underwent MRI were reviewed. The findings of MR imaging were retrospectively analyzed and the clinical symptoms were also analyzed. Results:　MR imaging demonstrated solitary mass in 6 cases, and multiple mass in 2 cases. On T1WI, the lesions showed homogeneous low signal in 3 cases, and mixed high and low signal in 5 cases. On T2WI, the lesions presented as homogeneous high signal in 3 cases and inhomogeneous high signal in 5 cases. All 8 cases with Gd-DTPA administration, marked enhancement was seen. All lesions of 8 cases showed mass-like enhancement. Conclusion: It is a difficult task to make the correct diagnosis of the tumor-mimicking PACNS, and this disease entity is often misdiagnosed as tumor by MRI. The comprehensive understanding of the MRI characteristic features would be helpful in diagnosing the tumor-mimicking PACNS, thus avoiding the devastating injury caused by surgery. The definite diagnosis relies on brain biopsy.

DOI:
Objective: To probe the alteration of cerebral blood flow(CBF), cerebral blood volume(CBV) and mean transit time(MTT) of cerebral contusion and laceration with CT perfusion(CTP) within 48 hours after closed traumatic brain injury(TBI). And to investigate the value of CTP on predicting the lesion size on non-contrast CT(NCCT) one week later. Methods: NCCT and CTP were performed in 18 patients suffering from cerebral contusion and laceration within 48 hours after TBI. NCCT was repeatedly made 1 week thereafter. CBF, CBV and MTT were measured in three different regions: the hemorrhagic area, the surrounding hypodense region, and the perilesional normal-appearing parenchyma. All these parameters of the mirror region of contralateral hemisphere were also recorded. The area with abnormal density or abnormal color on initial NCCT and CBF-, CBV-, and MTT-derived maps were measured and compared with the area measured on the same slice on NCCT 1 week later. Results: The CBF and CBV of hemorrhagic areas and its surrounding hypodense region of cerebral contusion and laceration decreased obviously[the CBF were (2.42±1.62)ml/(100g·min) and (10.58±6.45)ml/(100g·min) separately and the CBV were (0.62±0.41)ml/100g and (1.53±0.47)ml/100g respectively]. The CBF and CBV parameters of hypodense region were more variable. MTT of hemorrhagic area and its surrounding hypodense region were prolonged predominantly[(16.10±8.45)s and (9.69±6.31)s separately]. The whole area of cerebral contusion and laceration showed noticeably enlarged during the first week after trauma. In comparison with the initial NCCT and MTT map, CBF and CBV maps were proved to be more congruent with the findings of NCCT at 1 week(66.67% and 50% respectively). According to initial NCCT and MTT maps, the area of lesions were more often underestimated compared to the follow-up CT(77.78% and 72.22% respectively). Conclusions: The perfusion of cerebral contusion and laceration decreased obviously, with pronounced alteration on CBF and CBV at the hemorrhagic regions. The paramaters of CBF and CBV were more variable than those of other areas. This study suggested that CBF and CBV maps could be more accurate for early predicting the area of lesions 1 week after TBI.

SHAREN Gao-wa;JIANG Ying;JIANG Yu-xin;LIN Shou-qing;SUN Ai-jun;WANG Ya-ping
DOI:
Objective: To investigate the effects of breasts in post-menopausal women under hormone therapy(HT) by using ultrasonography and to evaluate its clinical value. Methods: During the post-menopausal and transition period, women were divided into two study groups, HT group and control group. Using ultrasonography to monitor the changes of glandular section thickness, breast duct width and breast structure in both breasts. Results: ①The breast glandular section thickness in the HT group has no significantly change. The breast glandular section thickness became thinner in the control group and there was a significant difference(P<0.01). ②The breast duct width had broadened in all groups(P<0.01). ③There was no obvious different in the breast structure between the HT group and control group. There is no obvious correlation between breast structure changes and mammary carcinoma. Conclusions: It seems that low dose HT has no obvious effect on occurences of mammary carcinoma at long-term. To monitor the breasts by ultrasound is a simple and reliable method during HT.

DOI:
Objective: To perform a Meta-analysis comparing current noninvasive imaging methods[18F fluorodeoxyglucose(FDG) positron emission tomography(PET), PET/CT, and CT] in the detection of residual tumor after radiofrequency ablation of hepatic malignancies. Materials and Methods: MEDLINE, EMBASE, Cochrane library and some other databases, from January 1966 to April 2010, were searched for initial studies. All the studies published in English or Chinese relating to the diagnostic value of 18F-FDG PET, PET/CT, and CT for patients with residual tumor after radiofrequency ablation of hepatic malignancies were collected. Methodological quality was assessed. The statistic software called “Meta-Disc 1.4” was used for data analysis. A covariate analysis was used to evaluate the influence of patient or study-related factors on sensitivity. Results: In 12 included studies, CT had the highest pooled specificity, 0.93(95%CI: 0.91~0.95); PET/CT had highest pooled sensitivity, 0.90(95%CI: 0.86~0.94). The AUC of PET, PET/CT and CT were 0.9037, 0.7372 and 0.9142 respectively. The pooled sensitivity, pooled specificity and AUC showed no statistical significance between PET alone and PET/CT. For CT, its diagnostic value decreased in differentiating residual tumor for patients with inflammatory reaction around the lesion. The pathological types of liver tumors also affect the diagnostic value of PET and PET/CT. There was heterogeneity among studies and evidence of publication bias. Conclusion: 18F-FDG PET and PET/CT can provide added diagnostic information compared with CT in patients after radiofrequency ablation of hepatic malignancies. FDG-PET/CT is a more sensitive method in the follow-up of hepatic malignancies after radiofrequency ablation, particularly in patients with liver metastases.

PEI Feng;XU Zhou-min;LI Na;HUANG De-mei;HE Ning
DOI:
Objective: To explore the safety and curative effect of high intensity focused ultrasound(HIFU) in the treatment of portal vein tumor thrombosis. Methods: Sixty-two patients with primary hepatocellular carcinomas complicated with portal vein tumor thrombosis(Grade Ⅰ～Ⅲ) were treated by HIFU. The treatment effects included imaging changes and clinical symptoms. The rates of local control, clinical benefit response(CBR), average survival period and the frequency of complication were evaluated. Results: The rates of local control were 88.9% in grade Ⅰ, 33.3% in grade Ⅱ, and 5% in grade Ⅲ. The CBR was 83.3% in grade Ⅰ, 54.2% in grade Ⅱ, and 20% in grade Ⅲ. Average survival period for grade Ⅰ, Ⅱ and Ⅲ was 15.3 months, 10.5 months and 6.1 months, respectively. No serious complications were seen in grade Ⅰ and grade Ⅱ. Upper gastrointestinal bleeding were observed in grade Ⅲ. Conclusions: HIFU was non-invasive, safe and effective palliative therapy for the patients with primary hepatocellular carcinomas complicated with portal vein tumor thrombosis. HIFU was effective for the patients who had bad general condition, hepatic dysfunction, ascites, and was intolerable to other treatments.

ZHANG Rui;FU Peng;PEI Zhuo;LU Jing-hong;NI Hai-yang;LI Li
DOI:
Objective: To evaluate the diagnostic value of MR imaging in inflammatory pseudotumor of the liver(IPL). Methods: The MR imaging features of 11 cases of IPLs proved by pathology were retrospectively reviewed and compared with pathologic findings. Results: Ten cases were diagnosed as benign lesions and one case mistaken for malignant tumors. Five were isointense and six were hypointense on T1WI. Three were hypointense and five were hyperintense and there were isointense on T2WI. None of the 10 IPL showed strong enhancement during arterial phase, only one showed mild enhancement; and moderate enhancement during portal venous phase and delayed phase. The feature of enhancement was multiple. Slight peripheral and eccentric enhancement during portal venous phase was detected in IPL. There was a few space in enhancement region and the peak of enhancement time was longer. Conclusion: The MR imaging findings of IPL are specific and it is possible that most of the IPL can be diagnosed combining with history.

786 The value of tumor to cortex index in MDCT in the differentiation ofangiomyolipoma with minimal fat from renal clear cell carcinoma
XU Hua-zhi;ZHENG Xiang-wu;CAO Guo-quan;YE Cai-er;ZHU Ji-ying
DOI:
Objective: To compare renal angiomyolipoma(RAML) with minimal fat with those of size-matched renal clear cell carcinoma(ccRCC) with three-phase tumor-to-cortex index in multiple-detectors computed tomography(MDCT). Materials and Methods: Twenty-one patients of RAML with minimal fat(confirmed by surgery and pathology) and 52 cases of RCC were evaluated. The data came from the First Affiliated Hospital of Wenzhou Medical College from July 2006 to July 2009. The attenuation of ROI(region-of-interest measurements within tumor and uninvolved renal cortex pre- and post-enhancement) was measured. The tumor to normal renal cortex enhancement index R[R=tumor(CTpost-CTpre)/cortex(CTpost-CTpre), in which CTpost was the CT value of ROI post-enhancement, CTpre was the CT value of ROI before enhancement] was calculated. χ2 test was performed for comparing patient sex. Two dependent t test was done for patient age, CT value pre- and post-enhancement, and the tumor-to-cortex enhancement index R between the two groups. The diagnostic performance of R value analysis in differentiating RAML with minimal fat from ccRCC was determined by using receiver operating characteristic(ROC) analysis. Results: The statistics differences between the RAML with mini-fat group and the RCC group in patient sex, age, and unenhanced tumor attenuation were significant(P<0.05). There was no difference between the two groups in tumor attenuation after contrast(including corticomedullary, nephrographic and excretory phase). The R value of ccRCC group was higher than that of RAML group on all three phases(P<0.01). The area under the ROC curve of corticomedullary, nephrographic and excretory phase was 0.719, 0.767, 0.748, respectively. Tumor-to-cortex enhancement index R on corticomedullary phase was the most effective parameter for distinguishing RAML from ccRCC with threshold value of 0.4649, 71.2% sensitivity and 81% specificity. Conclusion: Three-phase enhancement MDCT scan may be useful in differentiating RAML with minimal fat from ccRCC.
