Comparison of white blood and black blood T2* cardiovascular magnetic resonance at 3 Tesla
Background T2* relaxometry offers a non-invasive method to accurately quantify myocardial iron levels, thus aiding the diagnosis and assessment of prognosis of patients. Two T2* sequences are used clinically: the single breathhold multi-echo gradient echo white blood (WB) and black blood (BB) techniques. At 1.5T, BB T2* has superior reproducibility and fewer artefacts than WB T2*. We compared B...
متن کاملComparison of symptomatic and asymptomatic atherosclerotic carotid plaques using parallel imaging and 3 T black-blood in vivo CMR
BACKGROUND To determine if black-blood 3 T cardiovascular magnetic resonance (bb-CMR) can depict differences between symptomatic and asymptomatic carotid atherosclerotic plaques in acute ischemic stroke patients. METHODS In this prospective monocentric observational study 34 patients (24 males; 70 ±9.3 years) with symptomatic carotid disease defined as ischemic brain lesions in one internal c...
متن کاملIntracranial Arterial Wall Imaging using 3D High Isotropic-Resolution Black Blood MRI at 3.0 T
INTRODUCTION: The presence of intracranial vascular disease is highly predictive of stroke. However, disease prevalence may be underestimated due to the lack of an appropriate diagnostic tool to depict the intracranial vessel wall [1]. Black blood MRI (BBMRI) has emerged as an effective method to identify pathological features of extracranial vessels [2]. Recently, it has been extended to evalu...
متن کاملHigh resolution coronary MR angiography at 7 Tesla: comparison with standard bright blood and black blood imaging
Background The aim for ultrahigh field coronary MR angiography (MRA) is to convert the benefit of increased signal-tonoise ratio (SNR) to improved spatial resolution and thereby better vessel edge sharpness (VES), while vessel conspicuity is preserved. Furthermore, black blood coronary MRA has been shown to be an alternative technique to detect arterial remodeling in patients with coronary arte...
