Objective To study the feasibility of noninvasive detection of unstable plaques with ~(18)F-Fluorodeoxyglu-cose (~(18)F-FDG) PET/CT imaging. Methods Atherosclerotic plaques were induced in male New Zealand white rabbits. Animals were injected with FDG labeled with ~(18)F, then examined with PET/CT. Aorta was explanted for photography with digital camera, and ~(18)F-FDG uptake analysis. Thirty unstable plaques and 30 stable plaques were choosed so as to compare the quantitativly ~(18)F-FDG uptake. The number of macrophages and smooth muscle cells was detected by immunohistochemical technique. Results Experimental group showed inconsistent uptake of ~(18)F-FDG in the abdominal aorta. The results were confirmed in the ex vivo digital photo of the explanted aorta. The target to non target ratio (T/NT) and macrophages of unstable plaques were higher than stable plaques (P<0.01) , but smooth muscle cells obviously reduced (P <0. 01). Correlation analysis showed that there was a positive correlation between T/NT and macrophage content (r=0. 815,P<0. 01), and a negative correlation between T/NT and SMC content(r=-0. 684,P <0. 01). Conclusion ~(18)F-FDG PET/CT can constitute an attractive imaging method for the noninvasive detection of experimental unstable plaques.

ObjectiveTo explore the imaging of the thrombosis after pharmacological triggering of plaque rupture in atherosclerotic rabbit model by using 3.0 T high-resolution magnetic resonance imaging.MethodsTwenty male New Zealand white rabbits were divided into an experimental group (n = 16) and a control group (n = 4).The aortic wall injuries were induced by an intravascular balloon in experimental group rabbits after high cholesterol diet.The pharmacological triggering with Russell's viper venom and histamine was performed after 3 months of establishment of model.All of the animals underwent pre-trigger and post-trigger MR examinations including 3D time of fight (3D TOF),T1 WI,T2WI and post contrast T1 WI.Euthanasia was performed in all rabbits and gross anatomy and histological specimen of aorta were obtained.Comparing the location and length of the thrombus between MRI images and histopathology was used Pearson test.Comparing the calculated indexes of abdominal aorta between rabbits with and without thrombosis was used AVONA test and LSD-t test.Results After triggering,8 in 14 survived rabbits developed thrombosis in experimental group,meanwhile,no thrombus was found in control group.The accuracy of multi-sequences MRI for detecting of thrombus was 87.1％ (27/31).MRI data correlated with the histopathology regarding thrombus length ( r = 0.85,P ＜ 0.01 ) and thrombus location ( r = 0.94,P＜0.01 ).Compared with rabbits without thrombosis,the rabbits with thrombosis had narrower lumen of abdominal aorta in the pre-triggered MR images [ ( 5.71 ± 2.38 )mm2 vs.( 8.93 ± 5.36) mm2,P ＜ 0.01 ].ConclusionMRI is useful tool to determine the thrombosis and plaque rupture in atherosclerotic rabbit model.

Objective Compared the scan doses of the 64 multidetector CT (64-MDCT) in three different lumbar ac-quisition patterns, to determine the optimized one. Methods The water phantom was scanned by the 64-MDCT, and three groups were divided according to acquisition patterns: group A (128 ×0.625 mm), group B (48 ×0.625 mm), and group C (40×0.625 mm). For every group, the water phantom was scanned for 40 times. The volume of CT dose index (CTDIvol), the DLP and the effective dose were calculated and recorded. One-way ANOVA test was used to compare mean values. Results According to the values of CTDIvol, DLP, and effective dose, the three groups were ordered as follows, group A (128×0.625mm)>group B (48×0.625mm)>group C (40×0.625mm). In group C, the values of effective dose were reduced 17.45%and 10.32%, respectively, in comparison with that in group A and group B. Conclusion The 40×0.625 mm is the optimized pattern which had minimum radiation dose.

Objective To discuss the imaging diagnostic features of adrenal injury. Methods The imaging features of the 29 patients of adrenal bruise and hernatoma (20 male and 9 females, average age 37) were retrospectively analyzed. The clinical appearances were all flank and hack pain, local sensitive to percus-sion and associated injury appearance. Among the 29 cases, 25 cases(86%) had adrenal injuries on right side, 2 cases(7%) on left side, and 2 cases(7%) on both sides, and no apparent abnormality was found in the relevant endocrine examination after injury. CT (n=29), MRI (n=5) and ultrasonography (n=6) were checked. CT follow-up were taken in 23 eases. MRI (n=1) and ultrasonography (n=l) were followed as well. Results The first-time exam coincidences of CT, MRI and sonography were 28/29 (97%), 5/5 (100%) and 3/6 (50%) respectively. One case of simple right-side adrenal hematoma 3 weeks after injury wasn't clearly diagnosed by CT, which was later diagnosed by MRI. The CT features of adrenal bruise were local or diffuse intumescence and focus high-density hemorrhage shadow. The CT appearances of acute stage adrenal hematoma were round-like high-density shadow without enhancement and the diameters were 1-3 cm. MRI appearances of 5 cases of subacute and chronic phase hematoma were typical high signal of T1WI, T2WI and DWI and toroid low signal around T2WI. Hematorna was not be enhanced when CT or MRI en-hancement scanning, and formed characteristic "nut-like" image feature with toroid high-density or high sig-nal enhanced shadow forming around. Uhrasonography appearances of 3 cases of hematoma were abnormal shadow of the adrenal gland. Conclusions CT is the prior imaging method for adrenal bruise and hemato-ma. MRI has the characteristic appearance for the few cases which are difficult to be identified by CT and ul-trasonography. Characteristic "nut-like" image feature is helpful for the diagnosis and differential diagnosis.

Purpose 18F-FDG PET/CT,pathological and immunohistochemical analysis are adopted to explore the value of PET/CT in the early-stage calcification examination of atherosclerosis in rabbits and effects of Pioglitazone in treating early-stage calcification.Material and Methods Sixteen New Zealand male rabbits were randomly divided into two groups:Pioglitazone group and control group,witheight rabbits in each group.Atherosclerosis model was established.Rabbits in Pioglitazone group received gavage with Pioglitazone and were raised with high-fat diet for 20 weeks.Blood was drawn to exam high sensitivity C-reactive protein and matrix metalloproteinase-9.PET/CT was used to measure mean standardized uptake value (SUVmean) and maximum standardized uptake value (SUVmax).Rabbit aorta received immunohistochemical,the plaque area,density of macrophage,percentage of calcification area and apoptosis index between the two groups were determined and compared.Results On 20 week,high sensitivity C-reactive protein in Pioglitazone group (4.27±0.43 vs.6.51 ±0.91,P＜0.01),matrix metalloproteinase-9 (41.52± 1.99 vs.62.21 ±3.60,P＜0.05),SUVmean (0.55±0.18 vs.0.68±0.21,P＜0.01)and SUVmax (0.70±0.19 vs.0.82±0.30,P＜0.05) were obviously lower than those in control group.Plaque area,density of macrophage,percentage of calcification area and apoptosis index in control group were obviously higher than those in Pioglitazone group.Plaque area of related artery section was positively correlated with SUVmean (r=0.28,P＜0.01) and SUVmax (r=0.25,P＜0.05).Density of macrophage was positively correlated with SUVmean (r=0.50,P＜0.01) and SUVmax (r=0.46,P＜0.01).Percentage of calcification area was positively correlated with SUVmean (r=0.50,P＜0.01) and SUVmax (r=0.47,P＜0.01).Apoptosis index was positively correlated with SUVmean (r=0.61,P＜0.01)and SUVmax (r=0.60,P＜0.01).Conclusion Inflammation and macrophage apoptosis are of great importance in the early-stage of atherosclerosis.18F-FDG PET/CT imaging can be used to assess minor calcification.Pioglitazone can reduce inflammatory level of atherosclerosis of the experimented animals,inhibiting early-stage calcification.
