SUMMARY We evaluated 11 dogs using computerized transmission tomography (CTT); eight were studied after coronary occlusion and three served as sham controls. Ungated scans (1 cm deep) of the left ventricle (LV) were obtained from LV apex to base to d

Because of the increased use of intravenous injection of contrast material for the evaluation of cardiac structure and function by digital subtraction techniques, a study was done to assess the hemodynamic effects of contrast material when used in th

We studied the dynamics of left ventricular (LV) emptying in 8 patients with asymmetric septal hypertrophy (ASH), 6 patients with concentric hypertrophic cardiomyopathy (CHC), and 6 normal controls. Four patients with ASH had resting systolic gradien

Experimental pericardial inflammation was evaluated with ungated and cardiac gated computed tomography (CT) in 12 dogs, including 2 controls. All were studied during and after contrast infusion; in addition, several were sequentially imaged for up to

We studied 90 patients with congestive myocardial disease documented at cardiac catheterization (46 idiopathic, 39 ischemic, and 5 hypertensive) who underwent M-mode and two-dimensional echocardiograms every 2-3 months for up to 7 years (mean 3.4 +/-

We evaluated the density distribution (anterior-posterior) of the right lung in 19 acutely anesthetized supine dogs using computed transmission tomography (CTT). Eleven dogs served as controls, and eight received 0.12 cc/kg of intravenously administe

Two studies were performed to assess the importance of coronary reperfusion on pulmonary capillary endothelial permeability in 34 anesthetized dogs. The response of intravascular pulmonary blood volume (PBV) and extravascular lung water (EVLW) was ex

We evaluated pulmonary transit time in dogs and humans using digital intravenous angiography. Digital data were acquired in both the control state and after isoproterenol was administered to alter the inotropic state. When compared with the control v

To assess the effects of renal ischemia and reperfusion on in vitro magnetic relaxation times (T1 = magnetization recovery, T2 = spin echo), we evaluated the spectroscopic characteristics of the renal cortex from 25 rabbits. Eight served as controls
