Radionuclide determination of myocardial blood flow

Seminars in Nuclear Medicine, 1973
The diffusible-indicator method of determining tissue blood flow was devised by Kety and his associates, 1–3 who observed the washout of an intraarterially injected tracer from the tissue of interest, and found that it was proportional to tissue blood flow.

Quantification of PET Myocardial Blood Flow

Current Cardiology Reports, 2019
The aim of this review is to provide an update on quantification of myocardial blood flow (MBF) with positron emission tomography (PET) imaging. Technical and clinical aspects of flow quantification with PET are reviewed.The diagnostic and prognostic values of myocardial flow quantification have been established in numerous studies and in various ...

The Determinants of Regional Myocardial Blood Flow

1977
It is presumed that a region of myocardium does not always have the same blood flow. The purpose of this communication is to examine those factors which are determinants for changing regional flow. We have divided the determinants into three types. Those affecting a regional variation in blood flow which has a random distribution and a cyclic character

An Overview of Myocardial Blood Flow

1977
There are inherent difficulties in measuring myocardial blood flow because of several unique features of the coronary circulation. First, coronary blood flow is phasic, depending on phasic aortic pressure and the varying degree of resistance to flow offered by the myocardium during systole. Second, oxygen extraction of the myocardium is high while flow

Quantitative Assessment of Myocardial Blood Flow with SPECT

Progress in Cardiovascular Diseases, 2015
The quantitative assessment of myocardial blood flow (MBF) and coronary flow reserve (CFR) may be useful for the functional evaluation of coronary artery disease, allowing judgment of its severity, tracking of disease progression, and evaluation of the anti-ischemic efficacy of therapeutic strategies.

Isotope clearance and myocardial blood flow

American Heart Journal, 1964
R adioisotope techniques for the study of the circulation have evolved at a progressively accelerating rate during the 3.5 years since the earliest semiquantitative estimates of the linear velocity of blood flow were made with radium C and a Wilson cloud chamber.’ A wide variety of techniques have followed which are also based on the use of externally ...

Measurement of myocardial blood flow.

CRC critical reviews in clinical radiology and nuclear medicine, 1975
This paper represents a review of the recent literature on techniques to measure myocardial blood flow in man. A short discussion on flow meters in followed by a more detailed discussion of the radionuclide techniques used to measure myocardial blood flow.

Regulation of Myocardial Blood Flow

Abstract A comprehensive review of the physiology of the coronary circulation is beyond the scope of any book chapter. Accordingly, an effort will be made here to present just the basic principles that all practitioners of nuclear cardiology should understand.
