Myocardial ASL perfusion reserve test detects ischemic segments in initial cohort of 10 patients with angiographic CAD

Background Myocardial ASL is a technique for the assessment of myocardial blood flow (MBF) without contrast agents. It can be safely applied to patients with end-stage renal disease who are not candidates for first-pass imaging with contrast agents. Myocardial ASL perfusion imaging performed at rest and during adenosine stress provides perfusion reserve (MBFstress/MBFrest), which is a common in...

Mapping of Myocardial ASL Perfusion and Perfusion Reserve Data

INTRODUCTION: Arterial spin labeling (ASL) is an emerging tool for the assessment of myocardial perfusion and perfusion reserve in humans. This technique requires registration of multiple images and suffers from low signal-to-noise ratio (SNR) [1-4]. In this work, we present a novel approach for mapping perfusion and perfusion reserve based on ASL data. Unregistered spatial data is transformed ...

SPECT Myocardial Perfusion Reserve in Patients with Multivessel Coronary Disease: Correlation with Angiographic Findings and Invasive Fractional Flow Reserve Measurements.

UNLABELLED Quantification of myocardial perfusion reserve (MPR) is an emerging topic in nuclear cardiology with an expected diagnostic and prognostic incremental value, especially for patients with severe coronary artery disease. The advent of new dedicated solid-state cameras has opened new perspectives for perfusion quantitation in SPECT. We appraised the feasibility of perfusion reserve esti...

Quantitative cerebrovascular reserve measured by acetazolamide-challenged dynamic CT perfusion in ischemic adult Moyamoya disease: initial experience with angiographic correlation.

BACKGROUND AND PURPOSE CT perfusion is a much more readily accessible imaging method to assess cerebral hemodynamic status than single-photon emission CT. We prospectively assessed quantitative cerebrovascular reserve by using acetazolamide (ACZ)-challenged CT perfusion for evaluating hemodynamic impairment in ischemic adult Moyamoya disease and compared it with angiographic findings.
