Book Description
In this issue of MRI Clinics, guest editors Drs. Max Wintermark and Ananth Madhuranthakam bring their considerable expertise to the topic of MR Perfusion. Top experts in the field discuss all three MR perfusion techniques (DSC, DCE, and ASL), as well as provide separate articles on evaluation of gliomas, breast cancer, musculoskeletal, prostate, and heart. Contains 13 relevant, practice-oriented topics including perfusion imaging for brain tumors; dynamic susceptibility contrast (DSC) MR perfusion; arterial spin labelling (ASL) MR perfusion; MR perfusion imaging of prostate; dynamic contrast-enhanced (DCE) MR perfusion; MR perfusion imaging for breast cancer; and more. Provides in-depth clinical reviews on MR perfusion, offering actionable insights for clinical practice. Presents the latest information on this timely, focused topic under the leadership of experienced editors in the field. Authors synthesize and distill the latest research and practice guidelines to create clinically significant, topic-based reviews.

Book Description
This is the second edition of a useful introductory book on a technique that has revolutionized neuroscience, specifically cognitive neuroscience. Functional magnetic resonance imaging (fMRI) has now become the standard tool for studying the brain systems involved in cognitive and emotional processing. It has also been a major factor in the consilience of the fields of neurobiology, cognitive psychology, social psychology, radiology, physics, mathematics, engineering, and even philosophy. Written and edited by a clinician-scientist in the field, this book remains an excellent user's guide to t

Book Description
The acquisition of resting cerebral perfusion measures using magnetic resonance imaging (MRI) is one of the assessments of cerebrovascular health used to discern how well patients are coping with anatomical changes such as stenosis, and other factors impacting the supply of blood flow to the brain. Perfusion measures may be obtained using several MRI based techniques including arterial spin labeling (ASL) and dynamic contrast enhanced methods that rely on injected contrast agents such as gadolinium. Recently hypoxia-induced changes in deoxyhemoglobin have been used as a non-invasive contrast agent, measuring the resulting changes in blood oxygen dependent (BOLD) signals with MRI. With each approach, the means through which voxel-wise cerebral perfusion information is derived differs, leading to the development a variety of analysis methods in recent studies. This Research Topic is intended to attract manuscripts that advance the use of resting cerebral perfusion measures in clinical assessments of cerebrovascular health. In pursuit of this aim a better understanding of several aspects are needed.

Book Description
Several studies have suggested a correlation between impairment of cognitive function and asymptomatic carotid artery stenosis without ischemic cerebral brain lesions. Hypoperfusion has been discussed as a possible underlying pathophysiological cause. It remains unclear whether hypoperfusion alone without evidence of infarction is sufficient to cause cognitive decline. In this study, we evaluated cognitive performance and cerebral perfusion changes in patients with asymptomatic carotid artery stenosis by arterial spin labeling (ASL) perfusion MRI before and after revascularization therapy.Methods:17 asymptomatic patients with unilateral high-grade (u226570%) carotid artery stenosis without evidence of structural brain lesions underwent ASL perfusion MRI and cognitive testing (MMSE, DemTect, Clock-Drawing Test, Trail-Making Test, Stroop Test) before and 6-8 weeks after revascularization therapy by endarterectomy or stenting. Multiparametric perfusion maps (cerebral blood flow (ASL-CBF), bolus arrival time (ASL-BAT)) were calculated and analyzed by vascular territory. Relative perfusion values were calculated. Results:A significant impact of revascularization therapy was shown through multivariate analysis on all perfusion measures analyzed. MCA borderzones were identified as territories showing significant hypoperfuion at baseline post-hoc testing in both ASL-CBF and ASL-BAT. All perfusion alterations normalized after revascularization. No significant correlation of cognitive test results with perfusion parameters was observed. Cognitive Performance showed no significant change after revascularization. Conclusion:Our study was able to show perfusion alterations in asymptomatic patients with high grade carotid artery stenosis in the absence of structural brain lesions, which proved fully reversible after revascularization therapy. In this cohort of asymptomatic patients we did not observe an association of hypoperfusion with cognitive performance.

Book Description
ASL is an increasingly popular tool to study the brain. The aim of this primer is to equip someone new to the field with the knowledge to make informed choices about ASL acquisition and analysis. While providing a stand-alone introduction to this subject, the text can be read with others in the series for a comprehensive overview of neuroimaging.
