Purpose In this article, we discuss dynamic whole-body (DWB) positron emission
tomography (PET) as an imaging tool with significant clinical potential, in relation to …

A healthy, functional microcirculation in combination with nonobstructed epicardial coronary
arteries is the prerequisite of normal myocardial perfusion. Quantitative assessment in …

Each imaging modality has its own unique strengths. Multimodality imaging, taking
advantages of strengths from two or more imaging modalities, can provide overall structural …

Single-photon emission computed tomography (SPECT) allows the three-dimensional
visualization of radioactivity within the human body and is widely used for clinical purposes …

Purpose This work was set out to investigate the feasibility of dose reduction in SPECT
myocardial perfusion imaging (MPI) without sacrificing diagnostic accuracy. A deep learning …

Absolute myocardial blood flow (MBF) and myocardial flow reserve (MFR) provide
incremental diagnostic and prognostic information over relative perfusion alone. Recent …

The understanding of microvascular dysfunction without evidence of epicardial coronary
artery disease pales in comparison with that of obstructive epicardial coronary artery …

Background: Single photon emission computed tomography (SPECT) has limited ability to
identify multivessel and microvascular coronary artery disease. Gamma cameras with …

In this review, we will cover both clinical and technical aspects of the advantages and
disadvantages of organ specific (dedicated) molecular imaging (MI) systems, namely …

An overview of the theory of 4D image reconstruction for emission tomography is given
along with a review of the current state of the art, covering both positron emission …
