Objective: To investigate MRI characteristics of the primary brain B-cell lymphoma(PBBL) so as to diagnose accurately. Methods: Seventy-one patients underwent MRI examination, and they were found to have the single mass in their brain, and then all patients were performed diffusion weighted imaging and contrast enhanced examination at 25 s, 125 s and 185 s after contrast injection, respectively. Depending on pathological data, all patients were divided into groups, ADC values and signal intensity of non-contrast and contrast examination were measured and compared. Results: Fifty-eight patients had entire pathological data and were divided into three groups, including twelve patients with PBBL, 20 glioblastoma and 26 brain metastasis from lung cancer. For all groups, there were no statistical differences found among ADC values and signal intensity in non-contrast examination(P>0.05). In all phases of contrast enhancement examination, mean signal intensity of PBBL were compared with those of the other two groups respectively, relative coefficient between 25 s and 125 s was 1.0, differences were significant(P<0.05), whereas those between 25 s and 185 s, between 125 s and 185 s were not significant(P>0.05). The signal intensity of PBBL at all phases of contrast enhancement was compared with that of glioblastoma, differences were significant in 5 phase points, but compared with brain metastasis of lung cancer, those of PBBL at 11 phase ponts were significant and could be used differential diagnosis. Conclusion: MRI examination by multi-phases contrast enhancement is able to provide more information for differentiating PBBL from glioblastoma and brain metastasis of lung cancer. Meantime, we find that ADC value is not useful to make differential diagnosis of PBBL and other tumors.

DOI:
Objective: To assess the value of the combination of sonography with CT in the diagnosis and differential diagnosis of thyroid follicular lesions. Methods: CT and sonography findings of 135 lesions in 122 patients with thyroid follicular lesions were retrospectively analyzed, all of the patients had pathologic diagnosis. One hundred and twenty-two leisions in 109 patients with adenomatoid noduler goiter(ANG), 13 lesions in 13 patients with follicular carcinoma(FC) were included. A round or oval shape lesion which possesses internal homogeneous echo and a clear boundary acoustic halo was considered as characteristic follicular adenomatoid nodule(FAN) in sonography, and a lesion which possesses higher enhancement than thyroid was considered as characteristic FAN on CT. The sensibility and specificity of the characteristic sonographic sign, the computed tomgrphic sign, and the combiniation of sonogrphic and computed tomgrphic sign were analyzed respectively in the diagnosis of FAN. The characteristic sonographic sign, the computed tomgrphic sign, and ring calcification in FAN and FC were analyzed. Results: Among the 135 lesions in the group, 1 FAN and 2 FC were excluded because of acoustic attenuation of ring calification, the sensibility and specificity of the characteristic sonographic sign was 72.7%(88/121) and 54.5%(6/11) respectively; the sensibility and specificity of the characteristic computed tomgrphic sign was 68.9%(84/122) and 84.6%(11/13) respectively; and of the combiniation of sonogrphic and computed tomgrphic sign was 91.0%(111/122) and 61.5%(8/13). There was no statistical difference in the characteristic sonographic sign between FAN and FC(P＞0.05), but had statistical difference in the characteristic computed tomgrphic sign and ring calcification(P＜0.05). Conclusions: CT has higher specificity than sonography in the diagnosis of FAN, and the combination of sonography with CT can improve the specificity in the diagnosis of FAN; ring calcification and lower enhancement than the normal surrounding thyroid are helpful for the diagnosis of FC.

DOI:
Objective: To assess the applications of blending width(BW) and blending center(BC) in dual energy portal vein imaging with DSCT. Method: The dual energy scan was performed during the portal venous phase on 30 randomly selected patients. During this course, through adjusting the blending width and blending center, 6 groups of images were optimized and contrasted. The original images which weighting coefficient were 0.3 acted as the control group images. CT value of region of interest(ROI) of the portal vein trunk and the liver were measured in these 7 groups. And the differences of CT value between the two ROI were separately measured and analyzed. Results: The results showed that there were statistic differences between the 6 optimized groups and control group images. The optimizing and contrasting made the CT value of the portal vein trunk and the liver higher and made the differences of CT value between the two ROI larger. There were 3 optimizing and contrasting groups in the range of BW=100~200, BC=50~100. The increasing of the CT value was most obvious. There were differences between the 3 groups and the other groups, but there were no statistic differences among the 3 groups. Conclusion: The optimizing and contrasting imaging of DSCT can improve the image quality of portal vein without increase the dosage of contrast-medium. The range of BW=100~200, BC=50~100 are the recommend parameters for optimizing and contrasting of DSCT.

Objective: To assess the value of spectral CT imaging in differentiating malignant and benign serous cavity effusion on the basis of comprehensive analysis tools. Methods: Review 85 patients with histopathological or laboratory proven serous cavity effusion underwent spectral CT imaging from January 2012 to October 2012, including 14 cases of benign serous effusion and 71 cases of malignant serous effusion were reviewed. Using the spectral analysis software, the mean CT value of 140 kVp images and monochromatic images (40～140) keV, effective atomic number(eff-Z) and fat(water), water(iodine), water(calcium) were measured and the slope of spectral curve was measured. The differences of these spectral characteristic parameters were evaluated statistically. The curve type of benign group and malignant group were counted respectively. Results: The CT values on 140 kVp polychromatic images and 70~120 keV between benign and malignant didn’t show any statistically significant difference. There were statistically significant differences between benign and malignant at low energy keV(40~60 keV), and significant differences could be found at 130~140 keV. The eff-Z and the eff-Z distribution peaks of benign group were higher than that of malignancy(P<0.01). The fat(water), water(iodine), water(calcium) of malignant effusions were higher than that of benign effusion group(P<0.01). The slope of spectral curve of benign was higher than that of malignancy(P<0.01). The curve type of benign and malignant effusion could be different(P<0.01). Conclusion: The comprehensive analysis of the spectral CT provides a multi-parameter approach for identifying benign and malignant serous cavity effusion.

LU Zhao;SHAN Ming;WEN Feng;SHEN Jing-wei;LIU Zhao-yu
DOI:
Objective: To study the CT and MRI findings of ovarian cystadenofibromas． Methods: Thirty-five patients with cystadenofibroma(36 tumors) enrolled into this study. All were confirmed by pathology. In the 35 cases, 33(91.7%) were benign serous cystadenofibroma, 1 was benign mucinous cystadenofibroma(2.7%). Twenty-two cases underwent plain CT scan, among them 18 cases also received contrast-enhanced CT. Thirteen cases underwent plain MR scan, 12 of them received contrast-enhanced MR scan. Results: On CT and MR images, tumors were mainly soild in 2 cases, with mixed components in 6 cases, multilocular cyst in 12 cases, uniocular cyst in 16 cases. After enhancement, the solid components enhanced mildly and the solid component of multilocular cyst also enhanced mildly except two case in which the solid nodule enhanced markly. Three tumors had interior bleeding and necrosis, three tumors had cystic wall calcification, two appeared “honeycomb sign”. Conclusion: Variable amounts of fibrous stromas of ovarian cystadenofibomas made the spectrum of imaging features variable from a purely cystic tumor to a complex cystic tumor. Ovarian cystadenomas are unilocular cystic masses with diffuse or partial thickening of cystic wall and septations, or multilocular cyst with irregular wall component, or multilocular cyst with solid component. CT is helpful to judge the nature of lesions, but difficult to make a definite diagnosis, while MRI due to its excellent resolution should be the imaging modality of first choice for ovarian cystadenofibomas．
