Multiparametric cardiac magnetic resonance imaging with motion compensation
… diagnosed. Recently, it has been shown that T1-relaxation times can be used to characterize myocardial pathologies even if they are not localized but affect the entire myocardium (diffuse disease). Furthermore, T1 serves as a tissue specific quantitative diagnostic parameter which ensures …

Cardiac magnetic resonance imaging assessment of aortic stenosis to improve clinical care
… fibrosis non-invasively; diffuse fibrosis using T1 mapping and replacement fibrosis with the late gadolinium enhancement technique. I devised a novel measure of diffuse fibrosis, the indexed extracellular volume (iECV) and showed that these techniques can be used to divide patients into three …

Graphical interface for quantitative monitoring of 3D MRI data
… image section selection, (2) segmentation, (3) T1 mapping, and (4) statistical data analysis.

Anatomische und funktionelle Magnetresonanztomographie der menschlichen Lunge
… der pathologischen Verkürzung der Lungen-T1-Relaxationszeit auf ca. 900 ms wie bei Patienten mit Mukoviszidose (CF), so dass sowohl große Lungenperfusionsdefekte in Patienten mit CF als auch kleine ungefährliche Lungenentzündungen in „gesunden“ Probanden durch das MT-STIR-Verfahren gut …

Platination Kinetics: Insight Into Rna-Cisplatin Interactions As A Probe For Rna Microenvironments
… targets on each RNA were determined using RNase T1 mapping combined with MALDI MS, and dimethyl sulfate (DMS) probing. The kinetic studies were carried out under pseudo-first-order conditions and electrostatic properties were evaluated using Brønsted-Debye-Hückel and polyelectrolyte theories. …

Characterisation of phenotypes of inflammation, fibrosis and remodeling in chronic rheumatic heart disease using multiparametric cardiovascular magnetic resonance and autophagy markers
… cine imaging of the short and long axes, T1 mapping (MOLLI, 5(3)3, estimation of ECV and late gadolinium enhancement (LGE) imaging. For the cellular study, we analysed the immunoexpression of Beclin, LC3, p62, BAX, Bcl-2 and caspase-3 in patients confirmed with RHD and valvular heart …

MRI determined tissue characterization of myocardial infiltration and fibrosis in cardiomyopathy
… the extent of myocardial fibrosis through T1 mapping and as such it can be used as a prognostic indicator in amyloidosis and dilated cardiomyopathy.

Σύγχρονα δεδομένα του ρόλου της καρδιαγγειακής απεικόνισης στη διαστρωμάτωση κινδύνου στη μη ισχαιμική μυοκαρδιοπάθεια
… Παράλληλα, νεότερες τεχνικές CMR, όπως το T1 mapping και ο υπολογισμός του εξωκυττάριου όγκου (ECV), επιτρέπουν την ανίχνευση διάχυτης ίνωσης και συμβάλλουν στην αναγνώριση ασθενών υψηλού κινδύνου πριν από την εγκατάσταση έκδηλης δυσλειτουργίας. Η ηχωκαρδιογραφία, με δείκτες όπως το global …

Venous Thrombosis: Formation, Evolution And Resolution Imaging Using Non-Invasive MRI Techniques
… of non-contrast enhanced MRI sequences including T1 mapping, T2* mapping, Magnetization Transfer Contrast (MTC), and Apparent Diffusion Coefficients (ADC) maps for the<br/>detection of thrombus in a murine model of deep venous thrombosis. The second aim was to investigate the merit of a fibrin and …

Manganese-enhanced magnetic resonance imaging in cardiometabolic disorders
… by voltage gated L-type calcium channels causes T1 shortening and intracellular contrast enhancement on magnetic resonance. Manganese-enhanced magnetic resonance imaging therefore represents a novel non-invasive method of assessing intracellular calcium handling. It has been used previously to …
