The aim of this investigation is to determine the correlation of color Doppler (CD) and color Doppler Energy (CDE) imaging and measurements of ovarian stromal blood flow prior to controlled ovarian hyperstimulation (COH), predictors of success of COH and numbers of oocyte retrieved, especially in group of poor responders. Fifty-two patients on IVF treatment were included in this prospective cli...

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...

Ultrasound is the preferred imaging modality in diagnosis of vascular complications following cardiac catheterization and intervention. In some cases, however, bleeding surrounding the femoral vessels, may severely distort the color Doppler images, making detection of venous complications especially difficult. This report refers to such a case where post-catheterization haematoma was suspected ...

OBJECTIVE To determine if gray-scale ultrasound morphology in the presence or absence of intrauterine fluid and endometrial vascular morphology as assessed by color Doppler ultrasonography can discriminate between benign and malignant endometrium in women with postmenopausal bleeding. METHODS In a prospective study 95 consecutive women with postmenopausal bleeding and endometrial thickness > ...

RATIONALE Vein of Galen aneurysmal malformation (VGAM) is a rare complex malformation of the cerebral vascular system consisting of arteriovenous shunts between the vein of Galen and the cerebral arteries. PATIENT CONCERNS We present the case of a 31-year-old pregnant woman, para 1, gravida 1. DIAGNOSES At 26 weeks' gestation who was examined for an anechoic mass on the cerebral median midl...

Ultrasound examination has become the “golden standard” in follow-up of the development and complications in early pregnancy. With introduction of transvaginal sonography a possibility for early morphological and biometrical ultrasound examinations has been significantly improved. The essential aim of an early pregnancy ultrasound is not only to diagnose a pregnancy, but also to differentiate b...

Doppler ultrasound is able to visualize blood flow by the change in frequency (Doppler shift) of sound waves that are reflected by moving blood cells inside the vessels (Doppler effect). Since hyperemia caused by vasodilation and angiogenesis can be the earliest detectable pathologic changes in the beginning of synovitis, Doppler ultrasonography can be used to assess inflammatory activity. In a...

OBJECTIVES To assess the proportions of response to neoadjuvant chemotherapy of breast cancer according to color Doppler ultrasound vascularity patterns. MATERIAL AND METHOD Prospective evaluation using gray scale and color Doppler ultrasound for number of vessels and feeding appearances of tumors as well as the changes in tumor sizes at before and after chemotherapy in 69 breast cancer patie...

BACKGROUND Ulnar nerve entrapment (UNE) has been diagnosed with clinical examination and electrodiagnostic studies. This study was designed to determine the value of a combination of grey-scale and color Doppler ultrasound findings in the diagnosis of patients with UNE. MATERIALS AND METHODS During May to August 2013 41 patients with UNE (proven by electrodiagnostic studies) and 44 healthy vo...
