Objective To investigate the image quality and radiation dose of 640-slice CT coronary arteriography(CTCA) with adaptive iterative dose reduction three-dimensional (AIDR3D)reconstrucction algoritym.Methods 640-slice CTCA with auto-matic exposure was performed on 84 consecutive patients.The original image data were reconstructed with AIDR3D and the filtered back-projection (FBP)algorithms at the image postprocessing workstation.Two experienced radiologists without knowing clinical information and reconstruction algorithms independently measured and calculated the image noise,signal-to-noise ratio and contrast-to-noise ratio with AIDR3D and FBP reconstruction algorithms.The qualitative image quality was assessed by using the 4-point scale.The radiation dose was calculated based on dose-length product exported on CT scanner.The quantitative and qualitative im-age quality with two kinds of reconstruction algorithm was analyzed statistically.Results The CTCA image noise was (27.20± 4.40)HU with AIDR3D and (60.00±12.40)HU with FBP,which with AIDR3D was decreased by 46.10% than that with FBP;the signal-to-noise ratio was 21.10 ± 5.10 with AIDR3D and 11.40 ± 2.80 with FBP,which with AIDR3D was increased by 84.70% than that with FBP;the contrast-to-noise ratio was 24.70±5.10 with AIDR3D and 13.50±3.20 with FBP,which with AIDR3D was raised by 82.20% than that with FBP,the differences in 3 indexes between the two kinds of reconstruction algorithm were statistically significant(P < 0.05 ).The CTCA qualitative image quality scores of proximal,middle and distal parts with AIDR3D were (3.90±0.30),(3.70±0.50)and (3.60±0.60)respectively,which all were higher than (2.60±0.60),(2.30± 0.60)and (2.10±0.70)with FBP respectively,the differences in 3 items between 2 kinds of algorithm had statistical significance (P <0.05).The total segments which could be used to diagnose the CTCA images with AIDR3D and FBP algorithms were 1 216 segments (96.50%)and 504 segments (40.00%),respectively,the difference had statistical significance(P <0.05).The mean ef-fective radiation dose was (2.10±1.00)mSv.Conclusion 640-slice CTCA with AIDR3D reconstruction algorithm not only signifi-cantly reduces the image noise than the conventional FBP algorithm,improves the quantitative and qualitative image quality,but also decreases the effective radiation dose.

Objective To study the compliance of examinees,and effectiveness of colorectal distension with partially automated and individualized insufflation of air for dual-energy CT colonography.Methods Forty-six healthy adult volunteers without history of conditions affecting gastrointestinal motor function were enrolled in this study.One day before CT examination,volunteers were asked to orally administered 60 mL 4% diatrizoate meglumine five times for fecal tagging.Air was insufflated by using an inflator in a partially automated and individualized manner.The volunteers were initially asked to assume the right lateral decubitus position,then slowly turn to the supine position.Insufflation rate began at 1.5 L/min,and decreased to 0.5 L/min at later stage.The necessity and volume of air insufflation were decided according to effectiveness of colorectal distension on CT scout images,self-reported sensation of volunteers,and intestinal pressure.Dual-energy CT scanning was performed,and dual-energy blended images were acquired.Compliance of volunteers was statistically analyzed.The effectiveness of colorectal segments distension was statistically analyzed by using Kruskal-Wallis H test.Results No abdominal pain,bloating,nausea or vomiting were noted in the 46 volunteers.All volunteers easily accepted colorectal insufflation of air,with grade 1 compliance.The effectiveness of colorectal distension of grades 1,2,3 and 4 were 0%,2.1%,5.1% and 92.8%,respectively.The difference of effectiveness of colorectal segments distension had no statistical significance(χ2=6.19,P=0.288).The effectiveness of insufflation was poor in 6 colorectal segments,including 2 in sigmoid colon and 2 in rectum.Effectiveness of insufflation was suboptimal in 14 colorectal segments,including 4 in descending colon,4 in sigmoid colon,and 3 in rectum.Conclusion Compliance of examinees with partially automated and individualized insufflation of air for dual-energy CT colonography is excellent,with good effectiveness of colorectal distension.

Objective To evaluate the diagnostic efficiency of Q?SPECT, CTPA, Q?SPECT/CT, and Q?SPECT/CTPA for pulmonary embolism (PE) in rabbit models. Methods (1) The PE models were constructed by injecting Gelfoam into the femoral vein of New Zealand rabbits ( n=30) . Q?SPECT, CTPA, Q?SPECT/CT and Q?SPECT/CTPA fusion images were obtained by integrated SPECT/CT. (2) All images were interpreted by two experienced nuclear radiologists who were blind to pathologic findings. The locations and numbers of lung lobes with PE were recorded respectively. ( 3) Serial sectioning of the lungs was per?formed and pathologically determined. (4) Se, Sp and Ac of different methods were compared using McNemar test;PPV and NPV were compared usingχ2 test. Kappa test was used to analyze the consistency between two nuclear radiologists. Kappa values<0.40 were interpreted as poor consistency, 0.40 to 0.75 as moderate con?sistency, >0.75 as good consistency. Results (1) Histologically confirmed emboli were present in a total of 26 pulmonary lobes and absent in 79 lobes. (2)The Se, Sp, Ac, PPV, and NPV of 4 imaging methods were:53.8%(14/26), 93.7%(74/79), 83.8%(88/105), 14/19, 86.0%(74/86) for Q?SPECT;73.1%(19/26), 96.2%(76/79), 90.5%(95/105), 86.4%(19/22), 91.6%(76/83) for CTPA;76.9%(20/26), 93.7%(74/79), 89.5%(94/105), 80.0%(20/25), 92.5%(74/80)for Q?SPECT/CT;88.5%(23/26), 91.1%(72/79), 90.5%(95/105), 76.7%(23/30), 96.0%(72/75) for Q?SPECT/CTPA. (3) McNemar test showed Q?SPECT/CT and Q?SPECT/CTPA had higher diagnostic Se for the detection of PE than Q?SPECT (χ2=4.167, 7.111, both P<0.05) , but without any significant difference with CTPA in diagnostic efficiency (χ2=0-2.250, all P>0.05) . Q?SPECT/CT had higher diagnostic Ac than Q?SPECT (χ2=4.167, P<0.05) . There was no significant difference between Q?SPECT/CT and Q?SPECT/CTPA in diagnostic effi?ciency (χ2=0.001-1.333, all P>0.05). (4)Kappa values of 4 imaging methods for radiologist 1 and 2 were 0.902, 0.915, 0.973, and 0.884. Conclusions Q?SPECT/CT imaging provides good Se and Sp. The diag?nostic efficiency of Q?SPECT/CT is better than that of Q?SPECT and is corresponded roughly to the efficien?cy of CTPA, Q?SPECT/CTPA. The diagnosis of two radiologists on Q?SPECT/CT images has the best con?sistency.

Objective: To investigate the effect of comprehensive feeding intervention on feeding quality and weight gain of premature infants. Methods: Eighty-one premature infants admitted to the neonatal intensive care unit (NICU) of our hospital from September 2016 to December 2018 were selected and randomly divided into the intervention group (n=41) and the control group (n=40). Infants in the control group received routine nursing and infants in the intervention group were given comprehensive feeding intervention on the basis of routine nursing includingimproved Y type gastric tube, gravity tube feeding in prone position, oral movement intervention, colostrum oral immunotherapy and kangaroo nursing. The changes of feeding process were compared between the two groups and the occurrence of feeding intolerance in the two groups was observed. Results: The duration of tube feeding and hospital stay were lower in the intervention group than in the control group (P<0.05). No statistically significant difference was found in birth weight and body weight at discharge between the two groups (P>0.05), but the average daily weight growth rate [g/(kg·d) ] after 1 week and the milk volume [ml/(kg·d)] at 1 week were higher in the intervention group than in the control group(P<0.05). The incidence of gastric retention, abdominal distension and vomiting in the intervention group was lower than that in the control group, but only the difference in the incidence of gastric retention (24.4% vs 47.5%) was statistically significant (P<0.05). The incidence of feeding intolerance was significantly lower in the intervention group than in the control group (24.39% vs 47.50%, P<0.05). Conclusion Comprehensive nursing intervention can shorten the tube feeding time of premature infants, promote the weight growth of premature infants, improve the feeding quality, reduce the incidence of feeding intolerance, and reduce the hospital stay of premature infants, so as to reduce the hospitalization cost, improve the quality of life of premature infants, and increase the satisfaction of parents.
