ObjectiveTo evaluate liver perfusion in pregnant women with hepatitis between 13 and 41 weeks of gestation by three-dimensional color power Doppler angiography (3D-CPA) vascular indexes. MethodsThis study involved 73 pregnant women with hepatitis and 44 healthy pregnant women who had the pregnancy examination between February 2012 and June 2013. We sampled in the area which was near the right lobe of the pregnant women liver's portal vein branch, and obtained the vascularization index (VI), flow index (FI) and vascularization flow index (VFI) via the virtual organ computer-aided analysis (VOCAL) method. Then, we compared the liver perfusion differences between the pregnant women with hepatitis and healthy pregnant women. ResultsThe hepatic flow indexes obtained by 3D-CPA were significantly different between the HBV-DNA viral load and the control groups. The cutoff values of the three vascular indexes of patients with hepatitis with HBV-DNA viral load and the healthy pregnant women were respectively VI=8.760 (P<3×10-4); FI=22.180 (P<6×10-7); and VFI=1.575 (P<3×10-5). ConclusionApplication of the 3D-CPA on liver perfusion may differentiate pregnant women with hepatitis B from normal ones, thus offer a support for clinical prevention and treatment for pregnant women with hepatitis B.
ObjectiveTo explore the value of ultrasonic score, blood vessels and vascular resistance index in predicting and diagnosing benign and malignant ovarian tumor. MethodsA total of 157 patients with ovarian tumors (77 benign and 80 malignant) aged from 19 to 68 years old (average 56 years) between January 2008 and June 2012 were enrolled in the research. The ultrasonic score, blood vessels and vascular resistance index were recorded, and the differences between benign and malignant tumor were compared according to the pathological diagnosis; Their sensitivities and specificities were analyzed with the preoperative prediction. ResultsIn benign ovarian tumor, ultrasound scores and blood vessels index were obviously lower than that in the malignant tumor (P<0.05); the vascular resistance index was much higher than that in the malignant tumor (P<0.05). The sensitivities and specificities in diagnosing malignant tumor were high when the ultrasonic score was ≥ 2, vascular index was>0.02/cm3, and blood flow resistance index was ≤ 0.6. The sensitivities were 92.5%, 90.0%, 87.5%, respectively; while the specificities were 90.9%, 89.6%, 84.4%, respectively. ConclusionUltrasonic score, blood vessels and vascular resistance index have significance for identifying benign and malignant ovarian tumors; ultrasonic score is more accurate which has high value of clinical application and popularization.
