This issue includes every subject relevant to neuroradiology that one may expect to encounter in a general emergency radiology practice. The most important concepts in emergent brain, spine, head & neck imaging, as well as pediatric nonaccidental trauma are reviewed, and the issue provides an excellent starting point for learning the fundamentals of emergency neuroradiology and can serve as a reference for those wishing to reinforce their current knowledge base.

The practice of Emergency Radiology has undergone rapid change in the last decade: as imaging procedures are increasingly performed within short periods of time after the arrival of patients to the emergency room, the expectation for near real-time interpretations (often by subspecialists) has gained popularity. Larger emergency centers provide 24 hour on-site coverage by well trained radiologists, while others rely on the services of equally well trained radiologists located off-site, taking advantage of modern universal interconnectivity. Either way, radiologists’ input is increasingly affecting the immediate outcome of patients presenting with acute symptoms. Radiologists have embraced the challenge to protect patient safety by seeking evidence-based data to support the proper utilization of CT (including the use of alternative imaging modalities) and radiologists and CT manufacturers together have worked intensely to find optimal methods to deliver the inevitable radiation.

Imaging of the breast can be one of the most challenging tasks in all of radiology. This issue not only covers all of the modalities (plain film, multislice CT, MRI, US, and nuclear medicine and molecular imaging it also provides discussions on the controversy regarding when women should be screened, the costs involved in breast imaging, and the appropriate use of screening.
