The Wearable Lower Limb Rehabilitation Exoskeleton Kinematic Analysis and Simulation.

In recent years, due to the increase in the incidence of traffic accidents, the number of people with limb injuries has also increased. At the same time, among the aging population, neurological diseases or cardiovascular and cerebrovascular diseases have caused many people to have limb hemiplegia. It has been clinically proven that the use of rehabilitation equipment can help patients with limb injuries to restore limb motor function.

Impact of time of flight and point spread function on quantitative parameters of lung lesions in F-FDG PET/CT.

Background: Image reconstruction algorithm is one of the important factors affecting the quantitative parameters of PET/CT. The purpose of this study was to investigate the effects of time of flight (TOF) and point spread function (PSF) on quantitative parameters of lung lesions in F-FDG PET/CT.

Methods: This retrospective study evaluated 60 lung lesions in 39 patients who had undergone F-fluoro-deoxy-glucose (FDG) PET/CT.

Quantification evaluation of Tc-MDP concentration in the lumbar spine with SPECT/CT: compare with bone mineral density.

Background: Despite recent technological advances allowing for quantitative single-photon emission computed tomography (SPECT), quantitative SPECT has not been widely used in the clinical practice of osteoporosis. The aim of this study is to evaluate the feasibility of quantitative bone SPECT/CT for measuring lumbar standard uptake value (SUV) in patients with different bone-mineral density (BMD), and investigate the correlation between SUV measured with Tc-methylene diphosphonate (MDP) SPECT/CT and BMD assessment by dual-energy X-ray absorptiometry (DXA).

Methods: A retrospective analysis of 62 cases Tc-MDP whole-body bone imaging and local lumbar SPECT/CT tomography were performed.

Different acquisition arcs for better imaging left ventricular wall in myocardial perfusion single photon emission tomography.

Objective: Conventional Single-photon emission tomography (SPET) myocardial perfusion imaging (MPI) is performed in the supine position range RAO 45-LPO 45, but the effect of other acquisition arcs on imaging quality have not been well described. In this study, we compared the radioactivity over left ventricle walls as measured by different acquisition arcs to identify the best specific applications.

Subjects And Methods: A total of 125 low-risk coronary heart disease patients underwent technetium-99m methoxy isobutyl isonitrile (Tc-MIBI) stress MPI, of which 52 received 360 acquisition with reconstruction using different 180 projections and the remaining 73 received conventional 180 (LPO 45-RAO 45) and left-side 180 (POST 180-ANT 0) acquisition consecutively.

[Standard uptake value of 18F-fluorine-2-deoxyglucose is correlated with the expression of estrogen receptor in duct carcinoma of breast].

Objective: To explore the relationship between the standard uptake value (SUV) of 18F-fluorine-2-deoxyglucose (18F-FDG) and the expression of estrogen receptor (ER) in duct carcinoma of breast, as well as their correlation.

Methods: From March 2004 to November 2006, PET/CT scans were performed to 41 patients (female, mean age (55.2 +/- 9.
