Objective:To investigate the difference of the functional connectivity within default-mode network related to posterior cingulated cortex between normal person, amnestic mild cognitive impairment (aMCI) patients and Alzheimer’s disease (AD) patients.And explore the potential value of resting-state functional magnetic resonance imaging in characterizing normal person, MCI and AD. The resting-state functional magnetic resonance imaging may provide [...]
With the improvement of people’s living standard, the outbreak of breastdiseases like breast cancer is growing year by year. As a result, it is ofincreasing importance to instantly and correctly distinguish benign andmalignant breast diseases which are treated differently. As is known, differentpatients of breast cancer have different clinical performance and biologicalfeatures, so it is [...]
【Background】Chronic obstructive pulmonary disease (COPD) is a preventable and treatable disease and characterized by airflow limitation that is not fully reversible. The airflow limitation is usually progressive and associated with an abnormal inflammatory response of the lung to noxious particles or gases. COPD is one of the leading causes of morbidity and mortality and one [...]
ObjectivesTo evaluate the diagnostic value of Magnetic Resonance. Imaging(MRI) in synovitis of common hip joint disease compared with computed tomography (CT) and X-ray, and explore the value of MRI diagnosis combined with clinical.Materials and methodsPhilips Achieva1.5T scanner.55cases of patients with clinically diagnosed or suspected of having synovitis of common hip joint disease with pathological examination [...]
Objective:To evaluate the prognostic value of somatosensory evoked potential (SEP) in prolonged coma patients with diffuse axonal injury and compare the prognostic accuracy of SEP with magnetic resonance imaging (MRI).Methods:43traumatic coma patients with diffuse axonal injury (DAI) received the examination of MRI at one month after injury. The patients were divided into three groups recording [...]
Objective：To study the imaging manifestations of CT and MRI indiagnosis of adrenal neoplasms，Improve the adrenal tumors imagingdiagnosis and differential diagnosis accuracy。Methods：The data of38patients on CT，MRI of adrenal neoplasmswere analyzed retrospectivly, as well as compared with operativefinding and histopathologic data.3.0T MRI scanner(PHILIPS，Netherl-ands)conventional magnetic resonance line axial T1WI、T2WI、STRR、FIEST sequences in all cases before operation.Artery and vein phase320CT [...]
Objective：Alzheimer’s disease(AD) as an unkown progressive and degenerativedisease is most primary form of dementia.Some research survey results aboutthe people of65years of age or older found that its prevalence was4.2%,butover the same period the people of dementia’s prevalence was6.3%.AD is aimplicit onset onslanght disease,early this disease is no teasy to find.Moreoverpresently no biological markers as diagnostic [...]
Objective:To explore the value of MRI in assessing the main pathologic changes of articular cartilagematrix(collagen and proteoglycan) of osteoarthritis．Methods:Thirty New Zealand white rabbits were randomly divided into A, B, C three groups.12rabbits were selected in both experimental group A and B.0.5ml0.4%collagenase II (2mg) or0.5ml1.6%papain(8mg) was injected into the right knee joint cavity of group A [...]
Objective:To investigate the applied value of3.0T magnetic resonance diffusion weighted imaging (MR-DWI) in the qualitative diagnosis of musculoskeletal benign and malignant tumors.Methods:60patients with musculoskeletal tumors pathologically confirmed by surgery or biopsy underwent conventional MRI and DWI (different b values of300,600and900s/mm2). Array spatial sensitivity the encoding technique (ASSET) and single-shot echo planar imaging (SS EPI) sequence [...]
