To determine if image magnification from ametropia or other factors required correction in the photogrammetric diagnosis of optic nerve hypoplasia, the following variables were studied using two standard 30 degrees field fundus cameras (Zeiss FF-3 and Kowa RC-2): (1) distance between the camera and the subject--variations in this distance do not change the(More)
Angiotensin-converting-enzyme (ACE) activity regulates left-ventricular growth. The deletion (D), rather than the insertion (I), ACE gene variant is associated with increased ACE activity and kinin degradation, and the absence (-) rather than the presence (+) of a 9 bp deletion in the gene encoding the bradykinin 2 receptor (B2BKR) is associated with(More)
BACKGROUND In vivo cardiac diffusion tensor imaging (cDTI) is uniquely capable of interrogating laminar myocardial dynamics non-invasively. A comprehensive dataset of quantative parameters and comparison with subject anthropometrics is required. METHODS cDTI was performed at 3T with a diffusion weighted STEAM sequence. Data was acquired from the mid left(More)

The winds of change are blowing through the field of cardiac imaging, and for those of us involved in cardio-vascular magnetic resonance (CMR), it is more akin to the fragrant &too from Gibraltar than the arid Saharan simoom referred to by Michael Ondaatje in the book En-glish Patient. Progress is occumng at a pace not dreamt of since intense interest was(More)
