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.
Topic Editor Prof. James Duffin contributed to the development of an automated end-tidal targeting device, RespirActTM and is employed by Thornhill Medical Inc. (Toronto, Canada). RespirActTM is currently a non-commercial research tool assembled and made available by TMI to research institutions to enable CVR studies.

This issue examines PET-MRI with evolving but potentially competing technologies. The guest editors have put together an extremely timely issue as practicing radiologists are increasingly curious about the role of diffusion weighted imaging with MRI as a competing or a complementary technique to PET.
This comprehensive and sophisticated video atlas comprises of more than 345 videos of some of the important and finest ophthalmic surgeries by approximately 200 contributors from all over the world. It would serve as a landmark reference not only for teaching residents in ophthalmic surgery practices, but also to experienced surgeons. This revised and updated second edition through its high quality videos demonstrates step by step, the latest techniques involved in both anterior and posterior segment surgeries along with a narration. The new technologies, especially Femtosecond Laser Refractive and Cataract Surgery, Minimally Invasive Surgery 23G and 25G, Posterior Segment Surgery and other new techniques have been described in the second edition. -- Publisher.
