uous real-time, cross-sectional imaging of blood vessels. We used this imaging catheter to compare intraluminal ultrasound with cineangiography in the measurement of vascular dimensions in animals and to assess the intraobserver and interobserver variability of the technique. Segmental deformation of vessel anatomy was produced by stenoses created with a tissue ligature or by balloon dilation. ...

© 2009 by the Iranian Society of Ophthalmology Published by Otagh-e-Chap Inc. 29 Purpose: To compare laser interferometry (LI) and ultrasound A-scan in measurement of axial length (AL) in eyes with asteroid hyalosis Methods: Twenty three patients with unilateral moderate to severe asteroid hyalosis determined by B-scan ultrasonography images participated in the study. The AL measurements were o...

BACKGROUND Diagnostic ultrasound provides a method of analysing soft tissue structures of the musculoskeletal system effectively and reliably. The aim of this study was to evaluate within and between session reliability of measuring muscle dorso-plantar thickness, medio-lateral length and cross-sectional area, of the abductor hallucis muscle using two different ultrasound machines, a higher end...

Introduction Serial measurements of the number of follicles and their growth by ultrasound is a standard way of monitoring fertility treatments using controlled ovarian stimulation. This is stressful for both the patient and the professional. Self-operated endovaginal telemonitoring (SOET) is more patient friendly and less time-consuming. Aim of the study The goal of the study is to see if th...

The fetal modified myocardial performance index (Mod-MPI) is a noninvasive, pulsed-wave Doppler-derived measure of global myocardial function. This review assesses the progress in technical refinements of its measurement and the potential for automation to be the crucial next step. The Mod-MPI is a ratio of isovolumetric to ejection time cardiac time intervals, and the potential for the left ve...

Objectives: The aim of the study was to investigate relationship between body mass index and ultrasound-measured subcutaneous adipose tissue (SCAT) thickness, in order propose an alternative non-invasive inexpensive method measure fat. We also evaluated liver size existence hepatosteatosis, investigated whether there a measurements (BMI), SCAT measurements. Methods: Height, weight, arm SCAT, um...

BACKGROUND Measurement of the common bile duct (CBD) has traditionally been considered an integral part of gallbladder sonography, but accurate identification of the CBD can be difficult for novice sonographers. OBJECTIVE To determine the prevalence of isolated sonographic CBD dilation in emergency department (ED) patients with cholecystitis or choledocholithiasis without laboratory abnormali...

INTRODUCTION Ultrasound of the lung and quantification of B lines was recently introduced as a novel tool to detect overhydration. In the present study, we aimed to evaluate a four-region protocol of lung ultrasound to determine the pulmonary fluid status in ventilated patients in the intensive care unit. METHODS Fifty patients underwent both lung ultrasound and transpulmonary thermodilution ...

Clinical measurement of pelvic floor muscle activity commonly involves techniques that are both physically and psychologically invasive. This study investigated transabdominal application of ultrasound to measure pelvic floor muscle action. The specific aims were to establish the face validity of ultrasound measures of displacement of the posterior bladder wall as a reflection of pelvic floor m...
