Introduction: Thyroid nodules are frequent occurrences, and whenever diagnosed, it is necessary to rule out of malignancy. Valuable diagnostic methods in this field are sonography and fine needle aspiration. In this study while investigating these two methods, we compared them with postsurgical pathologic findings. Materials and methods: This is a cross sectional, descriptive-analytical study. ...
OBJECTIVE The purpose of this study was to determine the value of duplex Doppler sonography in the characterization of focal hepatic lesions. SUBJECTS AND METHODS Duplex Doppler sonography with a 3-MHz transducer was performed prospectively on 198 patients with focal hepatic lesions. One hundred thirty-two patients had pathologically proved diagnoses, confirming 46 hepatomas and 86 metastatic...
BACKGROUND In in vitro fertilization (IVF) and intracytoplasmatic sperm injection (ICSI) treatment a large drop is present between embryo transfer and occurrence of pregnancy. The implantation rate per embryo transferred is only 30%. Studies have shown that minor intrauterine abnormalities can be found in 11-45% of infertile women with a normal transvaginal sonography or hysterosalpingography. ...
Vein of Galen aneurysm malformation (VGAM) is a rare congenital vascular anomaly. Although the cause of VGAM remains to be elucidated, the current hypothesis is persistence of the embryonic vascular supply, which leads to progressive enlargement and formation of the aneurysmal component of a typical VGAM. Here, we present a 36-year-old woman at 23 weeks' gestation (gravida 3, para 2) who was ev...
BACKGROUND AND PURPOSE Local hemodynamic information may help to stratify rupture risk of cerebral aneurysms. Patient-specific modeling of cerebral hemodynamics requires accurate data on BFV in perianeurysmal arteries as boundary conditions for CFD. The aim was to compare the BFV measured with PC-MR imaging with that obtained by using intra-arterial Doppler sonography and to determine interpati...
PURPOSE To compare blood flow velocity changes within the middle cerebral artery (MCA) during hyperventilation, as measured with by both transcranial Doppler sonography and MR imaging, with the diameter of the MCA as measured with MR imaging alone. METHODS The studies were performed in six healthy volunteers ranging in age from 22 to 31 years (mean, 27 years). Transcranial Doppler sonography ...
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...
Purpose: The aim of the study was to investigate the sonographic characteristics of the varices of pancreas in portal hypertension. Methods: We retrospectively reviewed the sonographic findings, case records and other diagnostic procedures of 11 patients with clinical features of portal hypertension of different etiology, all having sonographical changes suggesting presence of the pancreatic va...
OBJECTIVE The purpose of this study was to prospectively investigate the role of high-resolution and color Doppler sonography in the differential diagnosis of acute scrotum and testicular torsion in particular. METHODS Patients who underwent sonography for acute scrotum between April 2000 and September 2005 were included in the study. Gray scale and color Doppler sonography of the scrotum was...
BACKGROUND Placenta adhesive disorder (PAD) is one of the most common causes of postpartum hemorrhage and peripartum hysterectomy. The main risk factors are placenta previa and prior uterine surgery such as cesarean section. Diagnosis of placenta adhesive disorders can lead to a decrease of maternal mortality and morbidities. OBJECTIVE The purpose of this study was to compare the accuracy of ...
