DOI:
Objective: To quantitative assessment of brain iron deposition in the deep gray nuclei of multiple sclerosis(MS) by using susceptibility weighted imaging(SWI) technique. Materials and Methods: Twenty-five patients with clinically proven MS, which included 15 cases of released-remitting MS(RR-MS), 10 cases of secondary-progressive MS(SP-MS), and 26 cases of age-matched healthy volunteers as controls, all had MR examination associated with SWI. Bilateral phase value of globus pallidus(GP), putamen(PUT), head of caudate nucleus(HCN), substantia nigra(SN), red nucleus(RN) and thalamus(THA) were measured and compared with those of healthy volunteers, and then with those of the MS subtypes. Results: Compared to the controls, the mean phase values in bilateral RN(left: 1977.44±77.02, right: 1973.52±76.80) and SN(left: 1901.37±111.94, right: 1909.78±128.99) were significantly higher(P＜0.05). Whereas, no significant difference was present between the MS subjects and the controls in the bilateral CN, PUT, GP, THA and PUL other structures(P＞0.05), although the mean phase values of these structures were slightly lower in the MS rather than in the controls. Furthermore, in contrast with the SP-MS, the significant variation of phase values in the RR-MS was only obtained in bilateral GP(P＜0.05). Conclusion: As a powerful tool for quantifying brain iron, SWI can be helpful in evaluation abnormal iron accumulation in MS and further assessment processes of the disease.

DOI:
Objective: To discuss the value and the effect of CT perfusion imaging on the cerebral hemodynamic changes after subarachnoid hemorrhage. Methods: CT perfusion imaging was employed in 21 cases of subarachnoid hemorrhage(including 3 delayed cerebral infarction) as the experimental group and 7 patients as the control group to compare the difference of lobar CT perfusion parameters; comparing the CT perfusion photo and plain scan in the diagnosis of cerebral ischemia in the test group. Results: In the experimental group, CBF value was 21.35±3.42 with the occurrence of delayed cerebral infarction and 23.37±2.29 in the group without infarction while it was 26.59±2.47 in the control group, what was more, there was a significant difference between the two groups. Besides, as to the TTS value, it was 32.26±12.08 in the occurring of delayed cerebral infarction group and the value was 19.14±4.88 in the non-ischemic group and they had the obvious statistical difference, but no significant difference was showed in other perfusion parameters. Low perfusion area visible to the naked eye was detected on the perfusion photo of 10 patients in the study group, but low density changes were not found by CT plain scan. Conclusion: CT perfusion imaging is effective in assessing cerebral hemodynamics after subarachnoid hemorrhage.

ZHU Jian-zhong;ZHAO Lei;QIN Jian;CHENG Yu-hui;LIU Jun-jie
DOI:
Objective: To determine whether there is regional signal variation in the brain cortices of neurologically healthy adults on DW-MR images. Materials and Methods: The signal intensity(SI) on DW-MR images, contrast-to-noise ratios(CNR), and apparent diffusion coefficient(ADC) maps of the cerebral cortices at Signa HDe 1.5T were evaluated in 47 neurologically healthy subjects(27 men, 20 women, age range 31~82 years). Results: Increased SI on DW-MR images was seen in the cingulate gyrus and insula regardless of patient age. There were no statistically significant gender-or laterality-related differences(P>0.05). There was statistically significant differences existed in CNR among the cortical regions(P<0.001), and the signal intensity was higher in the cingulate gyrus and insula than in the other cortices(P<0.01). There were no apparent ADC differences among the cortices on ADC maps in males and females(P>0.05). Conclusion: The signal of brain cortices in the cingulate gyrus and insula was observed on DW-MR images of healthy subjects, and frequently manifest high SI. These findings may help in the recognition of cortical signal abnormalities as visualized on DW-MR images.

MENG Xuan;WANG Xin;LI Xing-jie;TONG Ming-hui;ZHOU Jun-lin
DOI:
Objective: To evaluate the diagnostic value of ultrasonography and magnetic resonance angiography(MRA) on acute internal carotid artery(ICA) occlusion. Methods: Color Doppler flow imaging(CDFI), transcranial Doppler(TCD) and MRA were used to screen 56 patients with unilateral acute ICA occlusion, and then to evaluate intracerebral artery hemodynamic changes of selected patients by TCD and MRA, the results were compared with digital subtractive angiography(DSA). Results: Forty-six cases of ICA occlusion located at extracranial proximal segment of ICA, 10 cases at intracranial segment of ICA. The demonstration rate of the posterior communicating artery(PCoA) on MRA was significantly higher than that on TCD(P<0.05). The opening rate of ophthalmic artery(OA) on TCD was significantly higher than that on MRA(P<0.05). There was no significant difference between synergetic using ultrasonography combined MRA and DSA in demonstrating collateral circulation. The peak velocity(Vp) and PI of middle cerebral artery(MCA) in the stenostic side were significantly lower than those on the healthy side(P<0.001). Conclusion: Ultrasonography and MRA could detect the hemodynamic changes and the collateral circulation in acute ICA occlusion. Ultrasonography diagnose lesions conveniently and quickly, which should the first choice of examination. Synergetic using ultrasonography and MRA may substitute or reduce the application of invasive DSA.

DOI:
Objective: To assess the effect of different reconstruction phase selection strategies on the image quality of MSCT coronary angiography in patients with irregular heart beats during examination. Materials and Methods: Twenty patients who experienced heart rate shift of more than 5 beats per minute(bpm) during CT coronary angiography were included in the study[mean heart rate (65.1±5.0)bpm]. CT coronary angiography examinations were performed with a 64-slice scanner. Image reconstruction based on relative timing was performed with multi-phasic reconstruction. Then the best phases at end-systolic and mid-diastolic stages were selected. Reconstruction based on absolute timing was performed with the reconstruction of the same slice. Then the best image at end-systolic stage was selected. Evaluation of stair-step artifacts were performed with a 4-point ranking scale. The results were analyzed with SPSS 11.5 for Kappa test and inter-group Chi-square test. Results: Two radiologists were in accordance with the rating of the stair-step artifacts(Kappa=0.991). The absolute delay end-systolic reconstruction and the relative delay end-systolic reconstruction provided superior image quality compared with relative delay mid-diastolic reconstruction(P<0.05). Absolute delay had relatively higher percentage of excellent images than relative delay in end-systolic stage. Conclusion: In patients with irregular heart beats, better image quality and less stair-step artifacts can be obtained with end-systolic reconstruction, especially with absolute delay.

DOI:
Objective: To assess and compare the differential diagnostic value of CT perfusion, MR perfusion and DWI in different kinds of malignant liver lesions. Methods: Thirty-nine patients underwent CT perfusion, MR perfusion and DWI scan. They were divided into 3 groups: 15 hepatocellular carcinoma, 11 cholangioma, 13 metastasis tumor. Calculate the ADC value of each case and compare the results of the 3 groups. When CT perfusion and MR perfusion was finished, separate the perfusion curve of liver lesion and hepatic parenchyma into two parts according to the TTP of spleen, calculate the SS of each part, then get the ratio of the two SS, named [SSr(ct)=SSpre/SSpost] to CT perfusion and [SSr(mr)=SSpre/SSpost] to MR perfusion. Then compare SSr(ct) and SSr(mr) of the 3 groups. Results: The ADC value of hepatocellular carcinoma, cholangioma and metastasis tumor was (1.04±0.13)×10-3mm2/s, (1.33±0.27)×10-3mm2/s, and (1.11±0.19)×10-3mm2/s, respectively. The results of cholangioma were significantly higher than hepatocellular carcinoma and metastatic tumor(P<0.05), but the difference between hepatocellular carcinoma and metastatic tumor was not significant(P=0.424). The SSr(ct) and SSr(mr) of the 3 groups were: 2.46±0.34 and 3.09±0.77, 1.03±0.21 and 1.12±0.21, 0.94±0.29 and 0.99±0.37. The results of metastatic tumor was significantly lower than those of hepatocellular carcinoma(P<0.05), either of the difference between hepatocellular carcinoma or cholangioma(P<0.05). The difference between metastatic tumor and cholangioma was not significant(P>0.05). Conclusion: To the differential diagnosis of hepatocellular carcinoma and metastasis tumor from cholangioma, DWI has advantage than CT perfusion and MR perfusion. While the perfusion evaluation of CT and MR has more advantage in the diagnosis of hepatocellular carcinoma and metastatic tumor.

DOI:
Objective: To explore the sensitivity and value of ultrasmall superparamagnetic iron oxide(USPIO) enhanced MRI black-blood sequence and white-blood sequence in the detection of atherosclerotic plaques in rabbits. Methods: Thirty New Zealand male rabbits were divided randomly into two groups: 20 animals in the experiment group, 10 animals in control group. Animal model of atherosclerosis(AS) was induced with aortic balloon endothelial injury and high-fat diet feeding. There was no intervention to the rabbits in the control group. MRI examination included plain scan, USPIO enhanced black-blood sequence and white-blood sequence. The ability in demonstration of shape, number and component of the plaques between USPIO enhanced black-blood sequence and white-blood sequence was compared. A correlated study was done between MRI and pathological findings, as well as a statistical study. Results: Animal model of AS was successfully made in 12 rabbits. The central area of the plaques demonstrated a decreased signal on USPIO enhanced T2WI and T2*WI, but a dot-like filling defect on USPIO enhanced white-blood sequence. There were 67 plaques that were positive on Prussian blue staining within the MRI scanning scope. Although there was no difference in the detection of numbers of AS plaques between USPIO enhanced black-blood sequence and white-blood sequence, but the black-blood sequence was superior to the white-blood sequence in demonstrating of the components of plaques. Conclusion: USPIO could be phagocytosed by macrophages in the AS plaques of the rabbits, which could lead to the change of MR signal intensity. USPIO enhanced MR black-blood sequence can reveal the number and component of AS plaques and comply in the diagnosis and evaluation of the stability of AS plaques.

DOI:
Objective: To evaluate standardized uptake value(SUV) in both TrueX and OSEM. Methods: ①NEMA IEC Body Phantom experiment. ②Clinical study: 40 oncological patients were reconstructed by TrueX and OSEM. SUV and volume of 10～15 lesions in every patient were measured by TrueD software. Results: There was no significant difference of SUVmax(t=-0.145, P>0.05) and SUVavg(t=-0.141, P>0.05) between TrueX and OSEM according to both phantom experiment and clinical study. SUVmax of 65% lesions measured by TruxX was less than that by OSEM. There was significant difference of SUVmax when VOI50% was below 1cm3 or when SUVmax was above 15. Conclusion: There was significant difference of SUVavg and SUVmax between TrueX and OSEM in small lesions and lesions with high SUV. The results revealed that it is important to keep the same reconstruction method in follow up for response criteria.
