Objective To evaluate the application of 3.0 T magnetic resonance angiography (MRA) in follow-up after embolization of intracranial aneurysms with stent-assisted coils.Methods From June 2013 to June 2015,32 consecutive patients with subarachnoid hemorrhage due to ruptured intracranial aneurysms underwent stent-assisted coil embolization at the Department of Neurosurgery,the Sixth People′s Hospital of Shenzhen were enrolled retrospectively,including 12 males and 20 female,their mean age was 56±10 years.All patients were confirmed to be solitary intracranial aneurysms by digital subtraction angiography (DSA) before embolization.They were followed up with 3.0 T time of flight MRA (TOF-MRA) and contrast enhanced MRA (CE-MRA) at 1 to 2 years after embolization.DSA findings were served as the golden standard.The effect of aneurysm embolization (stabilization,further embolization,recanalization/recurrence) and patency of the parent arteries (without stenosis/mild stenosis,moderate to severe stenosis and occlusion) were compared.Results (1) The comparisons of evaluating the aneurysmal effects and consistencies of DSA among TOF-MRA,CE-MRA and TOF-MRA+source images after stent-assisted coil embolization were poor (Kappa=0.039,P=0.002),medium (Kappa=0.582,P<0.01),and higher (Kappa=0.615,P<0.01),respectively.(2) The comparison of the consistencies in the patency of the parent artery after stent-assisted coil embolization between TOF-MRA,CE-MRA and DSA were poor (Kappa=0.171,P=0.211;Kappa=0.376,P=0.010).(3) With the DSA findings as reference,the accuracy rates of TOF-MRA,TOF-MRA+source images and CE-MRA for interpretation of aneurysm embolization were 37.5% (12/32),75.0% (24/32),and 71.9% (23/32),respectively.TOF-MRA compared with TOF-MRA+source images and CE-MRA respectively,there were significant differences in the accuracy rates (χ2=9.04,P=0.003;χ2=7.63,P=0.006);there were no significant differences in the accuracy rates between TOF-MRA+source images and CE-MRA (χ2=0.08,P=0.777).(4) With the DSA findings as reference,the accuracy rates of TOF-MRA and CE-MRA for interpretation of the patency of the parent artery were 37.5% (12/32) and 62.5% (20/32) respectively.There was no significant difference in the accuracy rate (χ2=4.67,P=0.097).Conclusions The accuracy rate of 3.0 T CE-MRA for evaluating the embolization effect of intracranial aneurysms after stent-assisted coil embolization was superior to that of TOF-MRA.It can be used as a preferred non-invasive examination during the follow-up.TOF-MRA+source images are equivalent to CE-MRA,however,TOF-MRA and CE-MRA for the evaluation of the accuracy of patency of the parent arteries are low.For positive or indeterminate results of MRA examinations,the individualized analysis should be performed,if necessary,perform DSA examination.

Objective To evaluate the clinical value of 9 9 Tc m-HL91 as a tumor positive imaging agent in diagnosis of pulmonary neopl asms. Methods We performed 2 h,4 h planar and 4 h tomogr aphy fusion imaging after injection of HL91 on 42 patients with high probability of pulmonary cancer. Tumor-to-normal tissue background (T/N) ratios were meas ured for all scans. Results T/N ratios at 2 h,4 h planar and 4 h transectional imaging in malignant group were 1.50? 0.17 ,1.71?0.22 and 2.72?0.75, respectively; while in benign group, they were 1.21?0.10,1.25 ?0.22 and 1.49?0.36, respectively. 4 h delay T/N ratios in malignant group we re obviously higher than 2 h ( P 0.05). There were no remarkable differences of T/N ra tios in different phases and histological types of lung carcinoma. Using maligna nt transection ratio ( -1s ) as diagnostic threshold, the sensitivity , specificity and accuracy were 84.85% , 88.89% and 85.71% , respectiv ely. Using transection ratio( +1s ) of benign group as diagnostic th reshold , the sensitivity, specificity and accuracy were 90.91%, 88.89% and 95.2 4%,respectively. Conclusion The results indicate that as a tumor positive imaging agent 99 Tc m-HL91 is useful in diagosising pulmon ary neoplasms.

Objective To certify whether 99mTc-HL91 can be trapped in ischemic myocardium prominently for clinical imaging. Methods The model of myocardial ischemia in rabbits was prepared and the distribution of 99mTc-HL91 was observed. The distribution of 99mTc-HL91 in the whole body was also observed. Results The myocardium of the left ventricle supplied by LCX was ischemic according to the change of electrical physiology and the results of NBT dying. The radioactivity in the myocardium of left ventricle supplied by LCX was higher than that supplied by LAD. LCX/LAD: 120 min, 2.57; 180 min, 3.45. 99mTc-HL91 was mostly distributed in the liver and kidney, next, the stomach and intestine. It was excreted through urination and defecation. There was little radioactivity in the heart and lungs and it eliminated quickly. 99mTc-HL91 was eliminated quickly from blood, too. Conclusion Ischemic myocardium can trap 99mTc-HL91 more significantly and relatively prominently at 180 minutes of post-injection. 99mTc-HL91 can be used in myocardial hypoxia imaging.

Objective To investigate the role of large-diameter magnetic resonance imaging (MRI) simulation in target volume delineation in radiotherapy for nasopharyngeal carcinoma (NPC).Methods Eighteen patients with NPC underwent computed tomography (CT) simulation and MRI simulation scans and localization in the same body position,with SOMATOM Sensation Open 40-row 82-cm large-diameter CT simulator and Siemens 3T MRI MAGNETOM Skyra 70-cm large-diameter simulator,respectively.The gross tumor volume (GTV) and parotid glands were delineated on all images according to the ICRU Report 50/62,and MRI was applied to observe the changes in GTV and parotid volume during radiotherapy.Paired t-test was applied to analyze the differences between GTVCT and GTVMRI and between GTVnx-CT and GTVnx-MRI.Results GTVMRI decreased significantly compared with GTVCT,and the average volume decreased from (213.64±84.59) cm3 to (199.68±84.69) cm3(p=0.006).As for the volume of primary lesions in the nasopharynx,GTVnx-MRI was significantly smaller than GTVnx-CT,and the volume decreased from (95.75± 24.76) cm3 to (88.12±26.25) cm3 (P =0.001);as for the volume of cervical lymph nodes,GTVnd-MRI was significantly smaller than GTVnd-CT,and the volume decreased from (117.89± 72.69) cm3 to (111.56± 70.69) cm3 (P=0.018).The targets delineated by CT and MRI did not overlap completely,with major differences in skull base bone and cervical soft tissue.The volume of both parotid glands delineated on MRI image was higher than that delineated on CT image,with a major difference in the deep lobe.MRI showed that GTV was reduced by 82.64± 16.87% during radiotherapy,and the volumes of the left and right parotid glands were reduced by (32.7± 23.95) % and (34.7± 21.72) %,respectively.Conclusions The delineation of target volume based on MRI simulation is more accurate than that based on CT simulation and can achieve a smaller volume range,which helps to guide target volume delineation in radiotherapy for NPC accurately.

Objective To analyze the function connection of the brain in smokers with resting-state fMRI.Methods Resting-state fMRI data of 53 smokers (smoking group) and 53 non-smokers (control group) were observed.The subjects in smoking group were divided into small or large amount smoking subgroup,as well as mild or severe addiction subgroup.The fractional amplitude of low-frequency fluctuation (fALFF) values of all subjects were calculated,and the differences of fALFF values and whole brain functional connectivity were observed.Results Compared with control group,fALFF significantly increased in the left limbic lobe,and decreased in the right superior temporal gyrus in smoking group.Compared to small amount smoking subgroup,fALFF significantly increased in the right superior temporal gyrus,and decreased in the bilateral limbic lobe in large amount smoking subgroup.Compared with mild addiction subgroup,fALFF significantly increased in the bilateral middle frontal gyrus,and decreased in the left limbic lobe in severe addiction subgroup.There are many increased and decreased functional connectivity brain areas in smoking group compared with control group.Conclusion There are many activity changes in addiction related brain areas and less in emotion control areas in smokers,and some brain areas activation changes are related to smoking amount and addiction level.
