3y F clinically normal Beagle. Images a–i were acquired with contrast primarily in the chambers and vessels of the left side of the heart.
Images k–q (next page) were acquired following a delay in which contrast material enhances structures of both the left and right side
of the heart. Images a–d and j–l were acquired in the transverse plane and are ordered from cranial to caudal. Images e–f and m–n were
acquired in the dorsal plane and are ordered from dorsal to ventral. Image g was acquired in a long oblique plane approximating the
long axis of the heart. Images h–i and p–q were acquired in the sagittal plane and are ordered from left to right. The left atrium and right
ventricle in image q appear to be contiguous as a result of partial volume effect from image collimation and the tangential orientation
of the image plane in relation to the myocardial wall. See page 428 for Legend for Figures 4.4.5–4.4.15. (Figure continues on next page.)
