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...

background: in this study, we aimed to investigate the ability of transvaginal doppler ultrasonography in predicting in vitro fertilization (ivf) outcome in women undergoing this procedure. materials and methods: in this prospective observational study, 65 infertile women underwent ivf procedure in isfahan, during 2013-2014, were studied. the pulsatility index (pi), resistive index (ri) and pea...

The aim of this study was to determine the effects of intramuscular injection of medetomidine on intra-renal arteriesresistive and pulsatility indices by duplex Doppler ultrasonographyin clinically normal adult domestic shorthair cats. For this purpose, twenty-six neutered adult healthy domestic shorthair cats (13 females and 13 males) were evaluated. B-mode, color Doppler and pulsed wave Doppl...

Background: Diagnosis of abdominal aortic aneurysm (AAA) is usually incidental, and surgical treatment, when indicated, may be open or endovascular. The drawbacks of computed angiotomography (CTA) and the advantages of Doppler ultrasonography have led to the development of alternative follow-up protocols, comparing the two methods. Objective: To determine validity indices for Doppler ultrasonog...

OBJECTIVE Cerebral herniation resulting from postischemic brain edema is the most common cause of death in patients with large cerebral infarctions. Early monitoring of intracranial pressure and application of necessary treatment procedures may have life-saving value. In this study, the data obtained by transcranial Doppler sonography were compared with clinical examination and the neuroradiolo...

25 Although color Doppler ultrasonography has been used to evaluate testicular blood flow in 26 many species, very little has been done in goat. Eight male Shiba goats were exposed to a 27 single intramuscular injection of either gonadotropin-releasing hormone (GnRH group; 28 1μg/kg BW) or human chorionic gonadotropin (hCG group; 25 IU/kg BW). Plasma 29 testosterone (T), estradiol (E2), and inh...

OBJECTIVE The purpose of this study was to evaluate ultrasonographically fetal growth trajectories, placental biometry, and umbilical artery (UA) Doppler indices in growth-restricted pregnancies of overnourished adolescent ewes and normally developing pregnancies of control-fed ewes. STUDY DESIGN Singleton pregnancies were established using embryo transfer in 42 adolescent ewes that were over...

All editorial matter in CMAJ represents the opinions of the authors and not necessarily those of the Canadian Medical Association. Pre-eclampsia and intrauterine growth restriction remain important causes of maternal and neonatal complications and death. These 2 conditions are felt to be the result of abnormal placenta formation involving abnormal trophoblast invasion of spiral arteries and a r...

Background Early prediction of adverse neonatal outcome would be possible by Doppler impedance indices of middle cerebral artery (MCA), umbilical artery (UmA), and descending aortal artery (AO) that result in decrease neonatal morbidity and mortality rate. The aim of the present study was a determination of optimal value for the ratio of MCA to descending aorta blood flow (MCA/AO) impedance ind...
