Splenic arteriovenous fistulas (AVFs) are rare lesions. Herein, we report a 40-year-old man with portal hypertension secondary to splenic AVF, which was primarily diagnosed by color Duplex sonography. Sonography revealed a non-pulsatile, cyst-like mass at the splenic hilum with an unusual comma-shaped extension. In color duplex sonography, complete color fill-in of the lesion with the character...

BACKGROUND AND PURPOSE The angle of insonation cannot be assessed with conventional transcranial Doppler sonography. Findings in healthy control subjects suggest that the angle is relatively small in routine clinical practice. Data regarding the angle in middle cerebral artery (MCA) stenosis are scarce. In this study, the angle and its effect on flow velocity measurements were assessed with tra...

Oculoplethysmography-carotid phonoangiography and periorbital directional Doppler sonography are two techniques widely used in the noninvasive evaluation of possible carotid artery disease. Recent advances with sonographic Doppler devices now permit measurement of blood velocities in the extracranial carotid arteries by direct scanning with a color coded Doppler imaging system. A prospective st...

Osler -Weber -Rendu disease or hereditary hemorrhagic telangiectasia(HHT) has been known to be an autosomal dominant disorder characterized by telangiectases and arteriovenous malformations of multiple organ systems(1). Hepatic involvement occurs in 8-31 % ofcases with HHTand includes telangiectases or arteriovenous fistulas associated with fibrosis and cirrhosis(2 , 3). Recent reports demonstr...

OBJECTIVE To evaluate the diagnostic assessment of enlarged lymph nodes, based on its perfusion pattern by taking tissue diagnosis as gold standard. STUDY DESIGN Analytical study. PLACE AND DURATION OF STUDY Departments of Radiology and Pathology, PIMS Hospital, Islamabad, from February to May 2016. METHODOLOGY Color sonography of patients with clinically, palpable cervical lymph nodes we...

PURPOSE To compare the detection of urinary stones using standard gray scale ultrasound for diagnostic accuracy using the color Doppler "twinkling sign". MATERIALS AND METHODS Our study population consisted of forty-one patients who demonstrated at least one urinary stone on unenhanced CT evaluation of the kidneys or ureters. Each patient was evaluated using gray scale ultrasound and color Do...

We report a case of a 50-year-old male who presented to the Emergency Department and was diagnosed with epididymo-orchitis. Sonographic evaluation of the testicle initially showed a normal, low resistance color Doppler waveform. The patient was admitted to the hospital. A follow up sonogram two days later demonstrated reversal of diastolic arterial flow on Pulse-Wave color Doppler imaging. Reve...
