ABSTRACT

Objective To evaluate the clinical value of fetal intelligent navigation echocardiography (5D Heart) in the display of key diagnostic elements in basic fetal echocardiographic views.Methods Using volume probe,3D volume datasets of the 209 normal singleton fetuses in the second and third trimesters were acquired from a four-chamber view.After processing the datasets by using 5D Heart,9 cardiac diagnostic planes were acquired and then the image qualities of key diagnosis elements of the heart and great vessels were graded by 3 doctors with different experiences of performing fetal echocardiography.Results Two hundred and sixty-two volume datasets were acquired from 209 normal fetuses,including 53 volume datasets collected when cardiac apex was in different directions,satisfactory datasets failed to be acquired in 27 fetuses because of the maternal obesity,the artifacts of fetal movement,or other influencing factors.Two hundred and thirty-one volume datasets of 182 fetuses could be used for 5D Heart analyzing and displaying,and the displaying rate of 9 standard diagnostic views was up to 88.2%.No significant difference was found when comparing the grading results of one observer in different periods of time,the grading results between two experienced doctors and the grading results among the experienced doctor and one relatively inexperienced doctor (P > 0.05).Conclusions 5D Heart has high reliability and repeatability in obtaining fetal echocardiographic diagnosis views and displaying fetal elemental diagnostic information.

ABSTRACT

Objective To evaluate the value of fetal intelligent navigation echocardiography with color flow imaging ( 5D Heart Color) in the display of key diagnostic elements in basic fetal echocardiographic views . Methods The heart volumes datasets of 220 fetuses were collected and the offline analysis was conducted . Pearson correlations was used to compare the detection rate of blood flow element between 5D Heart Color software and color Doppler flow imaging(CDFI) in basic fetal echocardiographic views ,and the detection rate of blood flow between normal fetuses ( control group ) and fetuses with cardiovascular abnormalities( case group) . Bland-Altman analysis was used to prove consistency and reliability of the results . Results Totally 384 fetal heart volume datasets were collected from 220 fetuses ,and 317 volume datasets of 200 cases could be used for the analysis ,with the acquiring success rate of 82 .6% . 5D Heart Color software and CDFI showed a close correlation in displaying key cardiovascular blood flow information in key fetal echocardiographic diagnosis sections ( r =0 .88 , P <0 .05) ;The detection rates of blood flow elements in control group and case group were 91 .9% and 87 .3% ,respectively , with an average of 89 .6%( r = 0 .9 , P < 0 .05 ) . Bland-Altman analysis showed close consistency between inter- and intra-observations in the detection rates of blood flow elements ,and their 95% confidence intervals were ( -0 .1/+0 .09) and ( -0 .09/+0 .1) ,respectively ,and the points outside the 95% confidence interval were 5 .4%(17/231) and 5 .7% (18/231) ,respectively . Conclusions 5D Heart Color software shows similar usefulness in the displaying key blood flow elements ,comparing with CDFI , demonstrating higher reliability and repeatability in displaying fetal echocardiographic diagnosis views and diagnostic blood flow elements .

ABSTRACT

Objective To evaluate the value of fetal intelligent navigation echocardiography ( 5D Heart) and Virtual Intelligent Sonographer Assistance ( VIS-Assistance ? ) in the display of key diagnostic elements in basic fetal echocardiographic views . Methods The heart volumes data of 209 normal fetuses were collected and then the offline analysis was conducted . Processing of the built-in VIS-Assistance ? for each diagnosis plane was optimized . The display success rate and image quality difference of diagnosis images and diagnosis elements before and after the VIS-Assistance ? processing as well as the repeatability between observers were analyzed and compared . Results Totally 262 fetal heart volume data were collected from 209 fetuses ,and 231 volume data of 182 cases could be used for the analysis ,with the acquiring success rate of 88 .2% . For the display rate of 8 diagnosis sections of the 231 fetal heart volume data before and after VIS-Assistance ? processing ,abdominal transverse section at stomach level showed no significant difference ,while the other diagnostic sections showed significant differences ( all P < 0 .05) ,and the display rate after the processing was higher than that before the processing . For the image quality scores of diagnosis sections before and after VIS-Assistance ? processing ,abdominal transverse section at stomach level showed no significant differences ,while other diagnostic sections showed significant differences ( all P < 0 .01) ,and the image quality scores after the processing were higher than those before the processing . According to Bland-Altman analysis ,95% credibility interval of the total scores of 8 sections measured by different observers before and after VIS-Assistance ? were ( - 0 .17/ + 0 .18 ) and ( - 0 .17/ + 0 .18 ) , respectively ,6 .06% (14/231) and 3 .89% (9/231) of the points were outside the 95% credibility interval , and the rest had high consistency . Conclusions 5D Heart and VIS-Assistance ? technology can significantly improve the display rate of diagnostic section and image quality of element structures , and has high reliability and repeatability in obtaining fetal cardiac diagnosis sections and displaying fetal elemental diagnostic information .

ABSTRACT

Objective Malrotation of intestine with midgut volvulus is a special disease in newbo-rns.It is important of early diagnosis to avoid the risk of intestinal infarct and necrosis.We intended to ex-plore the value of early ultrasonographic diagnosis in malrotation of intestine with midgut volvulus,comparing with upper gastrointestinal imaging.Methods Ultrasonographic features and upper gastrointestinal imaging of 48surgically confirmed malrotation of intestine with midgut volvulus between January 2011and December 2014were retrospectively analyzed.Results All patients were comfirmed by operaion.The rotational degree of midgut volvulus were 90to 720°.In 43of 48patients (89.58%)of malrotation of intestine with midgut volvulus were diagnosed by ultrasonography.The typical ultrasonographic features were called “whirlpool sign”,which was the superior mesenteric vein and the mesentery around the superior mesenteric artery.In 35 of 48(72.92%)patients with malrotation were confirmed by the upper gastrointestinal imaging.The typical sign of the upper gastrointestinal imaging was the helical form of the distal duodenum and proximal jejunum located at middle abdomen.Compared with upper gastrointestinal radiographic examination,ultrasonographic examination had more sensitivity in diagnosis of malrotation of intestine with midgut volvulus (P﹤0.05). Conclusion Ultrasonographic examination have more sensitivity in diagnosis.Noninvasiveness,absence of X-rays,and low costs could make ultrasonographic examination a useful screening test in patients with sus-pected malrotation of intestine with midgut volvulus.“Whirlpool sign”could be considered a specific ultra-sonographic sign in diagnosis of midgut volvulus,which could provide reference for the clinical treatment of malrotation of intestine with midgut volvulus.

ABSTRACT

Objective To evaluate the preoperative value of dual contrast-enhanced ultrasound (DCEUS) on obstructive jaundice.Methods Seventy-nine patients with obstructive jaundice were included.DCEUS (percutaneous transhepatic contrast-enhanced cholangio-ultrasonography combined with intravenous contrast-enhanced ultrasound) was performed preoperatively.The biliary obstruction plane,degree and cause were observed.After surgery,the diagnostic accuracy of DCEUS was compared with final pathologic results respectively.Results The overall accuracy of DCEUS in determining the flat,degree and cause of biliary obstruction was 98.7%,98.7% and 93.7%,respectively.The DCEUS and golden standard were both almost perfect for assessing biliary obstruction with Kappa values of 0.979,0.837 and 0.975(P =0.000).The overall diagnostic accuracy of obstruction combined with obstruction plane,the extent and cause was 92.4%.Conclusions DCEUS could be considered a feasible,reliable,and exhaustive method for preoperative evaluation of obstructive jaundice.
