PURPOSE To investigate the precision, accuracy, and repeatability of water/fat imaging-based fat quantification in muscle tissue using a large flip angle (FA) and a fat reference for the calculation of the proton density fat fraction (FF). Comparison is made to a small FA water reference approach. MATERIALS AND METHODS An Intralipid phantom and both forearms of six patients suffering from lym...

Background: Body-composition assessment reflects infant growth and nutritional status but is limited by practical considerations, accuracy, and safety. Objective: This study evaluated the precision and accuracy of a new air-displacement plethysmography (ADP) system for pediatric body-composition assessment. Design: We used 24 phantoms constructed from bovine lean muscle and fat. The phantoms va...

Introduction The use of diffusion-weighted (DW) imaging with steady-state free precession (SSFP) for the diagnosis of bone marrow has been reported (1-2). One notable limitation of this approach is the contribution of fat (lipid) signal intensity within bone marrow to the DW signal (3, 4). Healthy bone marrow contains substantial amounts of lipids (20-70%). The lipid component is reduced in pat...

OBJECTIVE To evaluate the impact of the adaptive iterative dose reduction (AIDR) three-dimensional (3D) algorithm in CT on noise reduction and the image quality compared to the filtered back projection (FBP) algorithm and to compare the effectiveness of AIDR 3D on noise reduction according to the body habitus using phantoms with different sizes. MATERIALS AND METHODS Three different-sized pha...

Abstract This work presents a unique non-invasive method for monitoring glucose levels in blood using planar Yagi–Uda antenna as microwave sensor. The proposed antenna, operating at 5.5 GHz, exhibits directional radiation pattern with peak gain of 6.74 dBi. A low-cost FR4 material size 30 mm × 40 1.6 is used dielectric substrate. human finger phantom, comprising layers skin, fat, blood, and bon...
