background: carpal tunnel syndrome (ctu) is the most common neuropathy in the body and one of the most important causes of occupational disability. the aim of the present study was to compare the diagnostic power of doppler sonography and gray scale in diagnosing cts and their comparison with nerve conduction studies (ncv). methods: in this analytical study, diagnostic value of doppler and gray...

Anecdotal reports have described a false-positive "jet effect" or velocity increase in the carotid artery contralateral to an artery with significant stenosis or occlusion when using duplex Doppler sonography. In this study, the frequency, significance, and possible reasons for this finding were evaluated by a retrospective comparison of duplex sonography and angiography. Twenty-three patients ...

OBJECTIVES This study was aimed at evaluation of the diagnostic value of Doppler sonography for the assessment of abnormalities in the internal jugular veins (IJVs). METHOD One hundred and sixteen IJVs were assessed in 58 patients with associated multiple sclerosis. Findings of Doppler sonography were compared with results of the reference test: catheter venography. RESULTS At least one pos...

OBJECTIVE To determine some major characteristic differences between two consecutive successful and unsuccessful intracytoplasmic sperm injection (ICSI) cycles in poor responders. MATERIALS AND METHODS Sixty women with poor ovarian response as determined using the Bologna criteria underwent ICSI cycles following an unsuccessful trial. Some parameters of both cycles including age, body mass in...

This review will focus on the main findings of our experiments that used B-mode and color-Doppler ultrasonography during the preovulatory period to study the morphological and blood flow/perfusion changes of the preovulatory follicle in mares. The topics to be addressed herein will be: ultrasonographic characteristics of the preovulatory follicle; B-mode echotextural changes of the follicle wal...

BACKGROUND AND PURPOSE Although sonographic evaluation of cervical adenopathy by use of size criteria is effective, the sensitivity and specificity fall short of that required to make adequate judgments regarding neck dissection. Therefore, we tested whether the combined use of size criteria and Doppler sonographic findings would improve the predictive ability for metastatic cervical nodes. M...

BACKGROUND Whether salpingectomy affects ovarian function is controversial. In this study, ovarian function was assessed by antral follicle count, ovarian volume and ovarian stromal blood flow measured by three-dimensional (3D) power Doppler ultrasonography. The objectives of the study were to compare the ovarian function of the operated side with the non-operated side after unilateral salpinge...

Background: The assessment of the endometrial receptivity at the time of human chorionic gonadotrophin (hCG) is one of the key factors for success of all ART procedures. Aim: To assess, if 3D and 3D power Doppler assessment of endometrial receptivity before giving hCG, helps improving pregnancy rates in superovulation with IUI cycles. Settings and Design: A prospective randomized study of 2500 ...
