Determinants of exercise calf muscle perfusion in Peripheral Arterial Disease (PAD)
نویسندگان
چکیده
Background In patients with PAD, ankle-brachial index (ABI) does not correlate well with time to claudication and lacks the ability to quantify tissue perfusion, therefore limiting the development of new therapies. Arterial spin labeling (ASL) MRI is a novel non-contrast technique that measures peak calf muscle perfusion noninvasively at a microvascular level. We sought to analyze the relationship of traditional risk factors for PAD and levels of exercise-induced calf muscle perfusion measured by ASL MRI.

ASL demonstrates higher and more homogenous calf muscle perfusion with post-occlusion hyperemia than with exercise
Background Pulsed arterial spin labeling (PASL) is a non-contrast MRI technique capable of quantifying calf muscle perfusion with comparable accuracy to contrast enhancedMRI perfusion in normal subjects and peripheral arterial disease (PAD) patients. Peak perfusion can be achieved with exercise or during post-occlusion hyperemia. However, exercise stress may underestimate peak perfusion because...

Background Prior work demonstrated the utility of first-pass gadolinium-enhanced calf muscle perfusion MRI in patients with peripheral arterial disease (PAD). However patients with PAD often have advanced renal disease which prohibits the use of gadolinium-based contrast agents due to the concern for nephrogenic systemic fibrosis. ASL for quantification of calf muscle blood flow could provide a...

Background Quantitative contrast enhanced MRI (CE-MRI) may be valuable for calf perfusion assessment in peripheral arterial disease (PAD). The Kety equation describes the dynamic relationship between the concentration of gadolinium (Gd) in tissue and in arterial blood. ktrans is the rate at which Gd enters the interstitial space and it is determined by blood flow (F) as well as the Gd extractio...

Background The functional impairment caused by peripheral arterial disease (PAD) is difficult to evaluate objectively and quantitatively. Current methods used to assess the efficacy of therapeutic interventions in patients with PAD are limited by variability and changes representing the placebo effect. Recently, Gadolinium-enhanced first-pass (FP) MRI has emerged as a new method to assess perfu...
متن کاملArterial spin labeling perfusion cardiovascular magnetic resonance of the calf in peripheral arterial disease: cuff occlusion hyperemia vs exercise
BACKGROUND Assessment of calf muscle perfusion requires a physiological challenge. Exercise and cuff-occlusion hyperemia are commonly used methods, but it has been unclear if one is superior to the other. We hypothesized that post-occlusion calf muscle perfusion (Cuff) with pulsed arterial spin labeling (PASL) cardiovascular magnetic resonance (CMR) at 3 Tesla (T) would yield greater perfusion ...
