Anatomic study of carpal tunnel in adults using monoenergetic reconstruction of dual-energy computed tomography.

Objective: To seek optimal keV settings for imaging carpal tunnel in adults by dual-energy computed tomography (DECT) monoenergetic technique; to describe anatomic characteristics of carpal tunnel and to observe correlation between carpal bony and soft tissue structures.

Methods: DECT images of 20 wrists (11 left and 9 right wrists; 14 men, mean age 26.93±1.

Research progress in the pathogenic mechanisms and imaging of severe frostbite.

Purpose: This article reviews the pathological mechanisms and progress of imaging of severe frostbite to assist in the search for targets for clinical diagnosis and treatment of severe frostbite. This review also aims to provide strong evidence for clinical diagnosis and treatment of deep frostbite.

Methods: The review was based on the summary and analysis of the existing literature, and explored the pathological mechanism of deep frostbite and the advantages and disadvantages of imaging diagnostic methods.

Using the Compressed Sensing Technique for Lumbar Vertebrae Imaging: Comparison with Conventional Parallel Imaging.

Objective: To compare conventional sensitivity encoding turbo spin-echo (SENSE-TSE) with compressed sensing plus SENSE turbo spin-echo (CS-TSE) in lumbar vertebrae magnetic resonance imaging (MRI).

Methods: This retrospective study of lumbar vertebrae MRI included 600 patients; 300 patients received SENSE-TSE and 300 patients received CS-TSE. The SENSE acceleration factor was 1.

Reliability and Validity of Abdominal Skeletal Muscle Area Measurement Using Magnetic Resonance Imaging.

Rationale And Objectives: Skeletal muscle mass measurement is the most important element for diagnosing sarcopenia. MRI has an excellent soft-tissue contrast, which can non-invasively assess abdominal skeletal muscle area (SMA) as well as CT. This study aimed to assess the validity and reliability of abdominal SMA measurement by comparing CT and MRI based on the fat image of IDEAL-IQ sequence at the lumbar level mid-L3.

The protocol for the Prospective Urban Rural Epidemiology China Action on Spine and Hip status study.

The Prospective Urban Rural Epidemiology (PURE) China Action on Spine and Hip status (CASH) study focused on the prevalence of osteoporosis and spinal fracture in China. The aim of the PURE CASH study is to determine the prevalence of osteoporosis and spinal fracture, and explore the potential relationship between spinal fracture and bone mineral density (BMD). This study is a prospective large-scale population study with a community-based sampling and recruitment strategy.

Comparison Thigh Skeletal Muscles between Snowboarding Halfpipe Athletes and Healthy Volunteers Using Quantitative Multi-Parameter Magnetic Resonance Imaging at Rest.

Background: Magnetic resonance (MR) imaging provides a unique, noninvasive diagnostic platform to quantify the physiological and biochemical variables of skeletal muscle at rest. This study was to investigate the difference in thigh skeletal muscles between snowboarding halfpipe athletes and healthy volunteers via multiparametric MR imaging.

Methods: A comparative study was conducted between 12 healthy volunteers and 14 snowboarding halfpipe athletes.

Applications and Prospects of Non-viral Vectors in Bone Regeneration.

Introduction: Bone tissue has an intrinsic ability to repair and regenerate itself through a continuous remodelling cycle of resorption of old or damaged bone and deposition of new. However, significant morbidity and mortality arise when bone cannot heal itself. Effective bone regeneration strategy can improve the current clinical therapies of many orthopaedic disorders.

Targeted delivery of SNX-2112 by polysaccharide-modified graphene oxide nanocomposites for treatment of lung cancer.

Graphene oxide (GO) is a promising material for biomedical applications, particularly in drug delivery, due to its exceptional chemical and physical properties. In this work, an innovative GO-based carrier was developed by modifying GO with chitosan (CHI) to improve the biocompatibility, and followed by the conjugation of hyaluronic acid (HA), the target ligand for CD44, to realize the specific recognition of tumor cells and improve the efficiency of anti-tumor drug delivery. The resulting product GO-CHI-HA was loaded with an anti-cancer drug SNX-2112, which is the Hsp90 inhibitor.

The measurement of liver fat from single-energy quantitative computed tomography scans.

Background: Studies of soft tissue composition using computed tomography (CT) scans are often semi-quantitative and based on Hounsfield units (HU) measurements that have not been calibrated with a quantitative CT (QCT) phantom. We describe a study to establish the water (HO) and dipotassium hydrogen phosphate (KHPO) basis set equivalent densities of fat and fat-free liver tissue. With this information liver fat can be accurately measured from any abdominal CT scan calibrated with a suitable phantom.

[Sports injuries and illnesses during the 2008 Olympic Games and 2013 China National Games in Shenyang Division].

Objective: To retrospectively analyse the medical imaging examination results of the injuries and illnesses during the 2008 Olympic Games and 2013 China National Games in Shenyang Divison.

Methods: Collected and analyzed the health information and medical imaging examination results from Shengjing Hospital of China Medical University during the two games.

Results: There was 9 cases of sports injuries in the 2008 Olympic Games, mainly for knee, ankle ligament injury and muscle sprain, 36 cases of sports injuries in the 2013 China National Games, mainly for head traumas (9 cases), knee injuries (7 cases), ankle injuries (7 cases), shoulder injures (4 cases).
