Multislice multiecho T2* cardiovascular magnetic resonance for detection of the heterogeneous distribution of myocardial iron overload

A Pepe, V Positano, MF Santarelli… - Journal of Magnetic …, 2006 - Wiley Online Library
Purpose To assess the tissue iron concentration of the left ventricle (LV) using a multislice,
multiecho T2* MR technique and a segmental analysis. Materials and Methods T2* multiecho …

Heme oxygenase-1 induction remodels adipose tissue and improves insulin sensitivity in obesity-induced diabetic rats

…, M Li, DH Kim, SJ Peterson, L Vanella, V Positano… - …, 2009 - Am Heart Assoc
Obesity-associated inflammation causes insulin resistance. Obese adipose tissue displays
hypertrophied adipocytes and increased expression of the cannabinoid-1 receptor. Cobalt …

An accurate and robust method for unsupervised assessment of abdominal fat by MRI

V Positano, A Gastaldelli, A Sironi… - Journal of Magnetic …, 2004 - Wiley Online Library
Purpose To describe and evaluate an automatic and unsupervised method for assessing the
quantity and distribution of abdominal adipose tissue by MRI. Material and Methods A total …

[HTML][HTML] Deferasirox, deferiprone and desferrioxamine treatment in thalassemia major patients: cardiac iron and function comparison determined by quantitative …

…, L Pitrolo, M Missere, M Midiri, G Rossi, V Positano… - …, 2011 - ncbi.nlm.nih.gov
Background Oral deferiprone was suggested to be more effective than subcutaneous
desferrioxamine for removing heart iron. Oral once-daily chelator deferasirox has recently been …

Multicenter validation of the magnetic resonance T2* technique for segmental and global quantification of myocardial iron

A Ramazzotti, A Pepe, V Positano… - Journal of Magnetic …, 2009 - Wiley Online Library
Purpose To assess the transferability of the magnetic resonance imaging (MRI) multislice

Improved T2* assessment in liver iron overload by magnetic resonance imaging

V Positano, B Salani, A Pepe, MF Santarelli… - Magnetic resonance …, 2009 - Elsevier
In the clinical MRI practice, it is common to assess liver iron overload by T2* multi-echo
gradient-echo images. However, there is no full consensus about the best image analysis …

Pericardial rather than epicardial fat is a cardiometabolic risk marker: an MRI vs echo study

…, V Chubuchny, D De Marchi, V Positano… - Journal of the American …, 2011 - Elsevier
BACKGROUND: Several studies using echocardiography identified epicardial adipose
tissue (EPI) as an important cardiometabolic risk marker. However, validation compared with …

PPAR‐γ‐induced changes in visceral fat and adiponectin levels are associated with improvement of steatohepatitis in patients with NASH

…, F Bril, R Belfort‐DeAguiar, V Positano… - Liver …, 2021 - Wiley Online Library
Background and Aims Peroxisome proliferator‐activated receptor (PPAR)‐γ agonists decrease
hepatic/visceral fat (VF) and improve necroinflammation despite subcutaneous (SC) fat …

Standardized T2* map of normal human heart in vivo to correct T2* segmental artefacts

V Positano, A Pepe, MF Santarelli… - NMR in Biomedicine …, 2007 - Wiley Online Library
A segmental, multislice, multi‐echo T 2 * MRI approach could be useful in heart iron‐overloaded
patients to account for heterogeneous iron distribution, demonstrated by histological …

Early hypertension is associated with reduced regional cardiac function, insulin resistance, epicardial, and visceral fat

…, S Ghione, D De Marchi, B Scattini, V Positano… - …, 2008 - Am Heart Assoc
Mild-to-moderate hypertension is often associated with insulin resistance and visceral
adiposity. Whether these metabolic abnormalities have an independent impact on regional …
