The purpose of this paper is to describe imaging techniques and findings of T2-weighted magnetic resonance imaging (MRI) of edema in myocardial diseases. T2-weighted cardiac MRI is acquired by combining acceleration techniques with motion and signal suppression techniques. The MRI findings should be interpreted based on coronary artery supply, intramural distribution, and comparison with delaye...

Objectives We aim to explore and analyze the related influencing factors of liver cardiac iron overload in MDS patients detected by magnetic resonance imaging (MRI).Methods have T2* MRI 105 patients. Among them, 20 accepted examination before after chelation therapy (ICT). Results: found that adjusted ferritin (ASF) was significantly correlated with T2*. RBC transfusion volume, brain natriureti...

There are few papers on the combination therapy of deferiprone (DFP) and deferasirox (DFX) in iron-overloaded patients with transfusion-dependent β-thalassemia major (β-TM). A total of 6 patients with β-TM (5 males and 1 female) with a mean age of 23.8±5.8 years (ranging from 17 to 31) used this treatment regimen. The mean doses of DFP and DFX were 53.9±22.2 and 29.3±6.8 mg/kg/day, respectively...

OBJECTIVES Cerebral complications of infective endocarditis (IE) [particularly, mycotic aneurysm, visualized as a hypointense spot on T2*-weighted brain magnetic resonance imaging (MRI)] are associated with a high incidence of postoperative cerebral or subarachnoid hemorrhage. We have adopted a policy of performing elective open heart surgery after performing a MRI enhanced by gadolinium in suc...

The aim of this study was to determine the myocardial area at risk (AAR), infarction-core size (IS) and the salvaged myocardial zone (SMZ), and to evaluate the imaging and histological characteristics of intramyocardial hemorrhage (IMH) after myocardial infarction using non-contrast T2 mapping on 7T magnetic resonance imaging (MRI). Twenty Sprague Dawley (SD) rats were randomly divided into the...

INTRODUCTION Bone marrow lesions (BMLs) are features detected on MRI that are important in the pathogenesis of knee osteoarthritis. Since BMLs reflect heterogeneous pathologies this prospective cohort study examined whether BMLs detected using different MRI sequences are associated with distinct structural and clinical endpoints. METHODS A total of 297 community-based adults without knee pain...

BACKGROUND Assessment of degenerative changes of the cartilage is important in knee cartilage repair surgery. Magnetic Resonance Imaging (MRI) T2 mapping and delayed Gadolinium Enhanced MRI of Cartilage (dGEMRIC) are able to detect early degenerative changes. The hypothesis of the study was that cartilage surrounding a focal cartilage lesion in the knee does not possess degenerative changes. ...

High-resolution magnetic resonance imaging (MRI) may improve the preoperative diagnosis of focal cortical dysplasia (FCD) in epilepsy. Quantitative 9.4T MRI was carried out (T1, T2, T2* and magnetization transfer ratio) on 13 cortical resections, representing pathologically confirmed FCD (five cases) and normal cortex. Quantitative immunohistochemistry for myelination (myelin basic protein/SMI9...

Arrow highlighting left ACA displacing the left portion of the optic chiasm inferiorly. Also note focal hyperintensity in the right chiasm. B. (Top Right) Coronal T2 MRI: Arrowhead showing displacement of optic chiasm superiorly by supraclinoid cavernous carotid. C. (Bottom Left...

Superparamagnetic iron oxide (SPIO) nanoparticles generate superparamagnetism, thereby resulting in an inhomogeneous local magnetic field, which shortens the T2 value on magnetic resonance imaging (MRI). The purpose of the present study was to use MRI to track bone marrow mesenchymal stem cells (BMSCs) labeled with SPIO in a rat model of myocardial infarction. The BMSCs were isolated from rats ...
