Effects of Acute and One-Week Fatty Acid Lowering on Cardiac Function and Insulin Sensitivity in Relation with Myocardial and Muscle Fat and Adiponectin Levels

Autor: Ronald Borra, Hanna-Riikka Lehto, Helena Tuunanen, Juhani Knuuti, Patricia Iozzo, Jussi P. Pärkkä, Riitta Parkkola, Virva Lepomaki, Pirjo Nuutila

Publikováno v: Journal of Clinical Endocrinology & Metabolism, 97(9), 3277-3284. ENDOCRINE SOC

Background/Aim: We tested the hypothesis that a persistent reduction in free fatty acid (FFA) levels improves cardiac function and systemic insulin sensitivity via a reduction in the myocardial and skeletal muscle adiposities and a modulation in adip

Publikováno v: Journal of Hepatology, 54(3), 545-552. ELSEVIER SCIENCE BV

Background & Aims: Ectopic fat in muscle and liver is linked to obesity and type 2 diabetes. Recently, pancreatic lipid accumulation has also been associated with beta-cell dysfunction and reduced insulin production, leading to the development of typ

Publikováno v: Journal of Nuclear Medicine, 51(11), 1676-1683. SOC NUCLEAR MEDICINE INC

We assessed the ability of C-11-acetate PET/CT, MRI, and proton MR spectroscopy (H-1-MRS) to image localized prostate cancer and detect its aggressiveness, using qualitative and quantitative approaches. Methods: Twenty-one patients with untreated loc

Spirometry based respiratory gating method for cardiac PET and MRI imaging

Autor: Juhani Knuuti, Tommi Kokki, Mika Teräs, Sami Kajander, Nicolas Durand-Schaefer, Virva Lepomaki, Tommi Noponen

Publikováno v: 2008 IEEE Nuclear Science Symposium Conference Record.

A respiratory gating method based on spirometry was developed and tested during PET/CT and MRI studies. The method was compared to two commercial respiratory gating methods: the motion tracking system using infrared camera and respiratory monitoring
