Validation of Small-Animal Look-Locker Inversion Recovery (SALLI) Cine versus Cine MR in assessment of left ventricular function
نویسندگان
چکیده
Background Small-Animal Look-Locker Inversion Recovery (SALLI) is a novel imaging method that generates simultaneously cardiac T1 maps, cine MR and inversion recovery-prepared images for high heart rates. T1 mapping by SALLI has been tested and compared with histology, however the assessment of left ventricular (LV) function has not yet been validated. Our aim was to compare the measurement of LV function between the SALLI sequence and the standard Cine MRI sequence.

Assessment of cardiac function and myocardial morphology using small animal Look-Locker inversion recovery (SALLI) MRI in rats.
Small animal magnetic resonance imaging is an important tool to study cardiac function and changes in myocardial tissue. The high heart rates of small animals (200 to 600 beats/min) have previously limited the role of CMR imaging. Small animal Look-Locker inversion recovery (SALLI) is a T1 mapping sequence for small animals to overcome this problem. T1 maps provide quantitative information abou...

Background It has been shown that the concentration of gadopentetate dimeglumine (GdDTPA) in myocardium and blood can be assessed from T1 measurements, and be used to calculate the extracellular volume (ECV) of the myocardium. We hypothesized that diffuse myocardial fibrosis in a small animal model could be quantitatively assessed by measuring myocardial ECV using small animal Look-Locker inver...

Methods 8 rats had an inflatable balloon coronary occluder surgically inserted via thoracotomy. They were allowed to recover for 10-14 days. MRI was performed to obtain baseline measurement of ventricular function. T1 mapping was performed using the Small-Animal LookLocker Inversion Recovery (SALLI) technique. Without removing the animals from the scanner, the left coronary artery was occluded ...
متن کاملSimultaneous T1 mapping, cine imaging, and IR-prepared imaging of the rat heart using Small Animal Look-Locker Inversion recovery (SALLI)
Background: T1 mapping of the heart in rodents is challenging due to high heart rates, preventing the use of non-segmented MRI techniques that have been developed for human studies. We propose a novel acquisition and reconstruction scheme generating cardiac T1 maps, cine images and inversion recovery (IR)-prepared images at the same time. Methods: Small Animal Look-Locker Inversion recovery (SA...
