BACKGROUND The purpose of this prospective study was to determine the clinical usefulness of captopril renal scintigraphy and duplex Doppler sonography in detecting haemodynamically significant renal artery stenosis (> or = 60%) and predicting cure or improvement of hypertension following revascularisation. METHODS Twenty-eight patients with moderate or high index of clinical suspicion of ren...

Hepatic artery thrombosis after liver transplantation is a devastating event requiring emergency retransplantation in most patients. Early clinical signs are often nonspecific. Before duplex sonography (combined real-time and pulsed Doppler) capability was acquired in October 1984, 76% of all transplants in this institution referred for angiography with a clinical suspicion of hepatic artery th...

background: as delay in diagnosis of ectopic pregnancy is directly associated with increasing mortality, it studying the high sensitivity and specificity of transvaginal color doppler sonography as the most preferred imaging method with the most accurate and rapid diagnosis results seems to be necessary. therefore, this study aims to evaluate the diagnostic value of transvaginal color doppler s...

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...

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...

Knowledge of the nature of ovarian lesions is important in order to establish the correct treatment and, especially, to detect ovarian cysts that do not require surgical treatment. With the purpose of demonstrating the utility of transvaginal sonography with colour Doppler of ovarian functional ovarian cysts, 378 ovarian tumours were studied, comparing sonographic diagnosis with pathological fi...

The accuracy and the reliability of extracranial vertebral Doppler flow (continuous wave Doppler sonography) for the detection of intracranial vertebrobasilar lesions was studied prospectively in twenty-one patients with brainstem disturbances and/or coma. The Doppler findings were compared with cerebral angiography. Doppler sonography was highly reliable for both detection and exclusion of hig...

Reliable differentiation between obstructive and non-obstructive hydronephrosis is decisive for the further therapeutic management in infants. The results of renal Doppler sonography were compared with diuretic radionuclide renography and with the follow-up results in 33 patients (range: 21 to 98 days). In Doppler sonography, a resistive index (RI) of > 0.9 was considered to be abnormal in the ...

Our aim was to assess reproducibility of three different lumen reduction measuring methods--North American Symptomatic Carotid Endarterectomy Trial, European Carotid Surgery Trial, and common carotid--using power Doppler and color Doppler sonography before and after Levovist enhancement. We included 20 symptomatic patients with mild or severe carotid disease. North American Symptomatic Carotid ...
