BACKGROUND Intracardiac echocardiography (ICE) has played a limited role in defining the substrate for ventricular tachycardia (VT). The purpose of this study was to assess whether ICE could identify abnormal epicardial substrate in patients with nonischemic cardiomyopathy (NICM) and VT. METHODS AND RESULTS We studied 18 patients with NICM and recurrent VT who had abnormal echogenicity identi...
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 > ...
INTRODUCTION Age-related changes in muscle mass and muscle tissue composition contribute to diminished strength in older adults. The objectives of this study are to examine if an assessment method using mobile diagnostic ultrasound augments well-known determinants of lean body mass (LBM) to aid sarcopenia staging, and if a sonographic measure of muscle quality is associated with muscle performa...
BACKGROUND Previous studies have shown that leprosy multi-drug therapy (MDT) does not stop the progression of nerve function impairment. There are no prospective studies investigating the evolution of nerve anatomic abnormalities after treatment. We examined leprosy patients aiming to investigate the evolution of nerve ultrasonography (US) abnormalities and the risk factors for poor outcomes af...
Background: Fetal lung immaturity is a major problem in the management of elective birth with respect to predicting development infant respiratory distress syndrome (IRDS) neonate after birth.Aim and Objectives: The aim this study was evaluate validity measuring fetal thalamic echogenicity by ultrasound as marker maturity.Subjects Methods: This prospective observational that being carried out o...
Background and Purpose—We sought to assess the reproducibility, interobserver variability, and application to clinical studies of a new method for the quantitative assessment of carotid plaque echogenicity. Methods—Carotid plaques were scanned with the use of ultrasound, and their images were stored in a computer. They were normalized by assigning certain gray values to blood and adventitia, an...
