	761	Resting-state function MRI study on the effectiveness of aerobic exercise in patients with Alzheimer’s disease
		QI Ming, ZHANG Ling
		Objective: To evaluate the therapeutic effect of aerobic exercise in patients with Alzheimer’s disease(AD) quantitatively by functional magnetic resonance imaging(fMRI). Methods: Seventeen cases of patients with AD were randomly divided into training group(9 cases) and control group(8 cases). The fMRI data of baseline and 3 months later were got for the amplitude of low frequency fluctuation(ALFF) analysis and analysis of brain functional network. Results: The training group showed increased ALFF value of bilateral prefrontal and anterior cingulate cortex and brain network between centrality(BC) value compared with baseline after 3 months of training, while the BC value of training group was higher than those in control group after 3 months. The difference was statistically significant(P<0.05). Further analysis of the network hubs showed bilateral distribution after training, which was different from the asymmetric distribution before. Conclusion: Resting-state fMRI data suggest that aerobic exercise is helpful to recovery of cognitive function in patients with AD, providing a quantitative evaluation method of effectiveness.

Methods: Ninety consecutive patients who underwent prospective electrocardiogram-CCTA on a 256-MDCT scanner were randomized to three groups: group A, which received CM(350 mgI/mL), was scanned by using the conventional tube output(120 kV) with filtered back projection(FBP). Group B which received CM(350 mgI/mL) and group C which received CM(270 mgI/mL) had identical IDR adapted to body mass index and weight, and scanned by 100 kV with iDOSE4 level 4. The subjective IQ, objective IQ, radiation dose and iodine load were compared among the three groups. Results: There were no significant differences in the image noise, contrast-to-noise ratio and attenuation of coronary among these three groups. Group B and C had good scores of the subjective IQ(≥3), and it could satisfy the clinical use. There was no significant difference of lumen contrast between group B and C. No significant differences of sharpness, subjective noise, and acceptability of images were observed, but the contrast dose of group A was significantly higher than group B and C. Mean iodine load of group A were 36.9%～39.6% higher than group B and C, and there was no difference between group B and C. The effective radiation dose of group B and C was 37.9% lower than group A, and there was no difference between group B and C. Conclusions: Equivalent and adequate diagnostic IQ can be achieved by using different iodine-concentration contrast materials(270 mgI/mL and 350 mgI/mL) when the IDR were kept identical in low-dose 256-MDCT coronary angiography with iDOSE4 level 4, compared with the IQ by using conventional tube output and FBP.

	798	The critical point of the peripancreatic blood vessels by pancreatic cancer invasion can be removed
		LI Ming-shan1, MENG Fan-qin2
		Objective: To explore the critical point of imaging findings, in which the invaded peripancreatic blood vessels could be operability by surgery. Methods: A total of 76 cases of patients with distant metastasis-free pancreatic cancer confirmed by operative pathology or clinical treatment were enrolled, all of them underwent contrast-enhanced CT before operation. Among them, 66 patients underwent enhanced MRI scanning and three-dimensional vascular reconstruction. According to the images, the extents of pancreatic cancer invasion of peripancreatic vessels were divided into grade 0, grade 1, grade 2, grade 3, and grade 4. The numbers of vessels in each grade were counted and compared to the results of operation. Results: There were 138 vessels in 39 cases with invasion extent higher than grade 2, so the operations were given up. A total of 37 cases were assessed with the possibility of operative excision before operation. Among them, 25 cases accepted radical excision of pancreas, however, 12 cases accepted tumor resection or palliative therapy alone because of preoperative underestimate of the invasion extent of one or more vessels. In these 12 cases, the invasion extents of 16 arteries and 21 veins were underestimated. Operative excision could not be executed if the invasion extent was assessed as grade 3 and 4 during operation, while it could be executed if the invasion extent was assessed as grade 0 and 1 during operation. Moreover, operative excision depended on the condition of patients if the invasion extent was assessed as grade 2. Conclusion: Preoperative multi-phase CT, MRI scanning and 3D vascular remodeling, it is very important to evaluate the operability before operation. Level 2 arterial invasion and level 1 vein invasion can be the critical point of resection.
