Myocardial native T1 relaxation times are highly dependent on the blood T1 values
Background Pre(native) and post-contrast myocardial T1 time calculated from T1 mapping sequences on Magnetic Resonance (MR) is currently being applied to study diffuse myocardial fibrosis in various cardiac diseases both in research and clinical area. However, because myocardium is highly perfused, its T1 time may be influenced by that of blood. Our aim was to study this association in an anima...
متن کاملFree-breathing post-contrast three-dimensional T1 mapping: Volumetric assessment of myocardial T1 values.
PURPOSE To develop a three-dimensional (3D) free-breathing myocardial T1 mapping sequence for assessment of left ventricle diffuse fibrosis after contrast administration. METHODS In the proposed sequence, multiple 3D inversion recovery images are acquired in an interleaved manner. A mixed prospective/retrospective navigator scheme is used to obtain the 3D Cartesian k-space data with fully sam...
متن کاملMyocardial T1 responds to adenosine - normal values of stress T1 reactivity at 1.5T and 3T
Background Myocardial vasodilator reserve is an important surrogate marker of normal and abnormal cardiac physiology. Pharmacological vasodilator agents such as adenosine increase myocardial blood volume, which is expected to prolong the observed T1-relaxation. We explored the novel application of stress T1-mapping by assessing the response of myocardial T1 to the administration of adenosine in...
متن کاملApparent and true metabolizable energy values of feedstuffs for ducks.
Two experiments were conducted, each with 24 White Pekin ducks, to determine the AME and TME content of five feedstuffs for ducks. In each experiment, fasting losses were obtained from six ducks and six ducks were used for each feedstuff. Each experiment lasted 102 h with an initial 48-h period and a 54-h excreta collection period. During the first 48-h period, all birds were tube-fed dextrose ...
متن کاملA New Precision–Fed Chick Assay for Determining True Metabolizable Energy Values of some Poultry Feed Ingredients for Broiler Chickens
Two experiments were conducted to determine: first, the best time of excreta collection after force feeding of broilers to yield the maximal amount of excreta, and second, nitrogen-corrected true metabolizable energy contents of some poultry feedstuffs including yellow corn, soybean meal, corn gluten meal, canola meal and poultry by-product meal by a new precision-fed chick assay using 3-week-o...
