We report a case of middle-aged woman incidentally diagnosed with Takayasu arteritis during the ultrasonography of a thyroid gland nodule. Prominent collaterals of the thyroidal arteries and a thin common carotid artery with mural thickening and deficient intraluminal flow signals were initially depicted on the ultrasonography with color Doppler. Subsequent magnetic resonance angiography and co...

A 6-year-old presented with fever for 5 days and pain in left hypochondrium. The child had marked pallor, tender splenomegaly 3 cm below costal margin, and anemia (hemoglobin 5.4 g/dL). Peripheral smear showed trophozoites and gametocytes of P.vivax. Ultrasonography of abdomen showed spleen 11.4 cm with 4×2.7cm wedge shaped hypoechoic area suggestive of splenic infarct. On Color Doppler study, ...

Objective: To evaluate the accuracy of colour Doppler USG and b-mode preoperatively in detection ovarian malignancy using histopathological diagnosis as gold standard Methodology: This cross-sectional study was conducted at Fauji Foundation hospital Rawalpindi from June, 2017 to Jan, 2020 after seeking ethical approval committee A total 96 female patients having adnexal masses on ultrasound wer...

doppler ultrasound can provide important information about vascular problems through the analysis of blood flow wave-form. the purpose of this study was obtaining the normal images of color doppler and estimation of blood flow velocity parameters of femoral artery in rabbits. left and right femoral arteries of 8 healthy adult new zealand rabbits were evaluated. color and spectral doppler images...

As the development of Doppler ultrasonography, many cases of uterine arteriovenous malformation (AVM) have beed diagnosed. But there is no case of cervical AVM in pregnant uterus. We present a 33-year-old pregnant woman who was diagnosed with AVM of the uterine cervix during the midtrimester. Color Doppler sonography and magnetic resonance image were used for diagnosis. We performed Cesarean se...

BACKGROUND We evaluated shear-wave elastography (SWE) and color Doppler ultrasonography (US) features for fibroepithelial lesions (FELs), and to evaluate their utility to differentiate fibroadenomas (FAs) and phyllodes tumors (PTs). METHODS This retrospective study included 67 FELs pathologically confirmed (49 FAs, 18 PTs). B-mode US, SWE and color Doppler US were performed for each lesion. M...

Normal reference values for the resistance index, A/B ratio and pulsatility index of the umbilical artery obtained by Doppler ultrasonography are presented. The resistance index and A/B ratio values are very similar to those previously published, indicating no need to formulate normal values for different populations. The pulsatility index differed from other published values, probably reflecti...

Objective To observe and analyze the effect of color doppler ultrasonography (CDU) in uterine arterial embolization (UAE). Methods 160 cases of patients with uterine fibroid were selected in this study. CDU were performed on all patients before UAE as well as 5-9 days and 3-6 months after UAE, so as to observe the shape, size and ultrasonogram of the uterus and uterine fibroid, and the blood ...
