Significance of CT scan and color Doppler duplex ultrasound in the assessment of Abernethy malformation
BACKGROUND Abernethy malformation is a rare congenital vascular abnormality in which the portal vein bypasses the liver and drains directly into the inferior vena cava. Diagnosis is complex and requires good quality imaging methods to identify details in systemic and portal circulation in order to establish diagnostic confirmation and treatment strategy. In this study we highlight the significa...
متن کاملSubject Body Mass Index Affects Doppler Waveform in Celiac Artery by Duplex Ultrasound
OBJECTIVE The aim of this study is to evaluate the effect of body mass index (BMI) on peak systolic velocity (PSV) recording in the celiac artery (CA). SUBJECTS & METHODS Forty male participants were entered prospectively into the study. The subjects were divided into two groups according to their body mass index. Group A included subjects with BMI ≤25 Kg/m(2) and those in group B with BMI >2...
متن کاملDilated renal collecting systems: differentiating obstructive from nonobstructive dilation using duplex Doppler ultrasound.
Two patients with ileal loop urinary diversions, studied with real-time and Doppler sonography ("duplex sonography") of the kidneys, were shown to have dilated intrarenal collecting systems. Resistive index measurements calculated from the Doppler signal correctly identified obstructive dilatation in 1 case and nonobstructive dilatation in the other.
متن کاملRole of duplex Doppler ultrasound in the assessment of patients with postprandial abdominal pain.
In 10 patients with postprandial abdominal pain thought likely to be the result of mesenteric ischaemia Doppler ultrasound examinations of the superior mesenteric and coeliac arteries were performed both after fasting and a standard meal of 800 kcal. Compared with control values Doppler waveform analysis suggested seven abnormal vessels. Two patients had abnormal fasting superior mesenteric art...
متن کاملRole of Duplex Power Doppler Ultrasound in Differentiation between Malignant and Benign Thyroid Nodules
OBJECTIVE To evaluate the usage of duplex power Doppler ultrasound (PDUS) for the differentiation of benign and malignant thyroid nodules. MATERIALS AND METHODS We prospectively examined 77 thyroid nodules in 60 patients undergoing ultrasound-guided fine needle aspiration biopsy (FNAB). Each nodule was described according to size, inner structure, borders, parenchymal echogenicity, peripheral...
