Arterial Transit Time-corrected Renal Blood Flow Measurement with Pulsed Continuous Arterial Spin Labeling MR Imaging
PURPOSE The importance of arterial transit time (ATT) correction for arterial spin labeling MRI has been well debated in neuroimaging, but it has not been well evaluated in renal imaging. The purpose of this study was to evaluate the feasibility of pulsed continuous arterial spin labeling (pcASL) MRI with multiple post-labeling delay (PLD) acquisition for measuring ATT-corrected renal blood flo...
متن کاملEvaluation of gastroepiploic arterial grafts to right coronary artery using transit-time flow measurement.
OBJECTIVES The objective of this study was to analyse the relationship between the intraoperative transit-time flow measurement (TTFM) parameter values and the postoperative angiographic results of gastroepiploic arterial (GEA) grafts to the right coronary artery (RCA). We investigated whether the intraoperative TTFM parameter values are reliable indicators of early patency in GEA grafts to the...
متن کاملFlow-weighted arterial transit time mapping of the human brain
Introduction The knowledge of the arterial transit time, δa, from the labeling plane into the brain is essential for blood-flow quantification. In previous work, the MATISSE (Mapping of Arterial Transit times by Intravascular Signal Selection) approach for the mapping of δa was introduced (1). It relies on the use of short repetition times, TR, and the application of an amplitude-modulated shap...
متن کاملTransit-Time Flow Measurement: Letter to the Editor
Transit-time flow technology is considered as a quality of care in bypass surgery especially in off pump revascularization. Transit time flow measurement is a real time, direct, easy and handy tool for assessment quality of anastomosis and graft blood flow.
متن کاملArterial transit time imaging with flow encoding arterial spin tagging (FEAST).
Arterial spin labeling (ASL) perfusion imaging provides direct and absolute measurement of cerebral blood flow (CBF). Arterial transit time is a related physiological parameter reflecting the duration for the labeled spins to reach the brain region of interest. Most of the existing ASL approaches to assess arterial transit time rely on multiple measurements at various postlabeling delay times, ...
