Estimation of organ input function and plasma clearance from the cardiac curve in dynamic scintigraphy

European Journal of Nuclear Medicine, 1992
A theoretical description of the relationship between the count rate detected in the cardiac region of interest and the arterial organ input function in dynamic scintigraphy is presented. It is shown that, provided the time-activity curve for the heart is corrected for extra-cardiac and unlabelled activity, it is proportional to the arterial organ ...

Estimation of the left ventricular diastolic function with cardiac MDCT: Correlation of the slope of the time-enhancement-curve with the mitral annulus diastolic velocity

European Journal of Radiology, 2011
Patients with diastolic heart failure tend to have a poor outcome, similar to that for patients with systolic heart failure. The aim of this study was to explore the ability of MDCT to estimate the left ventricular diastolic function. Thirty patients with suspected coronary artery disease underwent MDCT and echocardiography.

Ventricular function curves from the cardiac response to angiographic contrast: A sensitive detector of ventricular dysfunction in coronary artery disease

American Heart Journal, 1974
Abstract Fifty cardiac catheterizations were performed in 44 patients undergoing evaluation for coronary artery disease. Ventricular function curves (VFC) were constructed by plotting the left ventricular end-diastolic pressure (LVEDP) and stroke work index (SWI) before and three to four minutes after a standard left ventricular angiogram.

Non-invasive quantification of cerebral blood flow for rats by microPET imaging of 15O labelled water: the application of a cardiac time???activity curve for the tracer arterial input function

Nuclear Medicine Communications, 2005
In-vivo quantitative cerebral blood flow (CBF) measurement using positron emission tomography (PET) has typically employed invasive arterial blood sampling procedure to determine the arterial input function (AIF). The present study was performed to provide a non-invasive quantitative CBF measurement technique for rats using a dedicated animal PET.CBF ...

Bedside Assessment of Total Systemic Vascular Compliance, Stressed Volume, and Cardiac Function Curves in Intensive Care Unit Patients

Anesthesia & Analgesia, 2012
Mean systemic filling pressure (Pmsf) can be measured at the bedside with minimally invasive monitoring in ventilator-dependent patients using inspiratory hold maneuvers (Pmsf(hold)) as the zero flow intercept of cardiac output (CO) to central venous pressure (CVP) relation.

Evaluation of cardiac function and venous return curves in awake, unanesthetized cialves with an implanted total artificial heart.

Transactions - American Society for Artificial Internal Organs, 1975
1) The implanted TAH offers a method of evaluating the effects of varying physiologic demands cardiac output and venous return. 2) Cardiac output and venous return measurements offer a method of evaluating system design of the device and driving and control-logic improvements in awake, unanesthetized animals. 3) The obtained cardiac function and venous
