The direction and velocity of the haemolymph in the vessels were measured by phase-contrast gradient echo sequences (PC-MRI) ( Lotz et al., 2002 ), using transverse or horizontal slices with a voxel resolution of 100×100 µm and a slice thickness of 1 mm with a combination of T R...

... flow magnetic resonance imaging (MRI) – to validate stroke volume measurements and end diastolic ventricular blood volume. This produced an estimate of ejection fraction in our study species, the red footed tortoise Chelonoidis carbonarius ( n =5), under isoflurane anaesthesia of 88±11%. After...

Staples ABSTRACT We discovered a previously undescribed orbital lipid depot in the thirteen-lined ground squirrel during the first ever magnetic resonance image (MRI) of this common experimental model...

... and water:fat ratio of WAT and BAT using magnetic resonance imaging (MRI). We found no evidence of torpor in the warm-housed animals, indicating that this species might not be an obligate hibernator, as previously assumed. Regardless of ambient temperature, BAT volume increased prior to winter, then decreased...
