Influence of arterial input function on hypoperfusion volumes measured with perfusion-weighted imaging.
BACKGROUND AND PURPOSE The arterial input function (AIF) is critical in determining hemodynamic parameters quantitatively with bolus-tracking MRI. We studied the effect of varying the location of measurement of AIF on the volume of hypoperfusion. We compared the volumes of hypoperfusion obtained with different AIFs with the final ischemic lesion volume. METHODS We included 13 patients with ac...
متن کاملQuantitative myocardial perfusion imaging using a step arterial-input function
Background Modern MRI myocardial perfusion protocols use rapid venous bolus injections, typically 3-5 ml/s of 5-15 ml of agent over a few seconds. The resulting arterial input functions are rapidly varying with high agent concentrations (Fig. 1A and 1B) and thus typically require high temporal resolution acquisitions (~1 sec), custom pulse sequences and complex processing methods for perfusion ...
متن کاملQuantitative three-dimensional myocardial perfusion cardiovascular magnetic resonance with accurate two-dimensional arterial input function assessment
BACKGROUND Quantification of myocardial perfusion from first-pass cardiovascular magnetic resonance (CMR) images at high contrast agent (CA) dose requires separate acquisition of blood pool and myocardial tissue enhancement. In this study, a dual-sequence approach interleaving 2D imaging of the arterial input function with high-resolution 3D imaging for myocardial perfusion assessment is presen...

متن کاملHow should tissue Doppler tracings be measured?
Tissue Doppler, an echocardiographic modality measuring velocities of solid cardiac structures by pulsed-wave or colour Doppler, after very early experiments was introduced clinically in the early 1990s and is one of the very few recent technical innovations in echocardiography to gain quick and near-ubiquitous clinical implementation. The most widely adopted application is the registration of ...
