Each day during the ASNR 56th Annual Meeting (June 2 – 7) in Vancouver, BC, Canada a case will be shown as the official Case of the Day. This has traditionally been ‘invite only’, but just like last year, this year one of the cases will be chosen from cases you submit to Radiopaedia.org.

In addition to one ASNR 2018 Case of the Day winner, Radiopaedia.org will also be showcasing a number of the best submissions as Radiopaedia.org “Cases of the Day” on its home page and through social media!


There are a number of prizes available:


The winner gets two great prizes:

  • Standard Room for two (2) nights at the meeting venue at Fairmont Waterfront Hotel and including complimentary daily in-room WiFi and health club access (value of USD $545). The prize is courtesy of the American Society of Neuroradiology (ASNR). The reservation can be used at any point during the ASNR 56th Annual Meeting dates from Friday, June 1 through Thursday, June 7. If you are not planning to attend the conference, then that’s ok. You will receive the prize either way, and you can, if you wish, transfer it. Any questions, please contact, Ashley Boser, at ASNR office, 630-574-0220, Ext. 231 or email: aboser@asnr.org.

In Memoriam – William Werner Orrison Jr (1949-2017)

William Werner Orrison Jr., M.D., M.B.A.

William Werner Orrison Jr., M.D., M.B.A. 1949-2017
William Werner Orrison 

William Werner Orrison died at age 68 on Oct. 19, 2017, in Las Vegas, Nev., of a non-specified neuro-degenerative disorder.

Born on April 2, 1949, in Louisville, Ky., Bill was the eldest child of Agnes Rutherford Miller “Ruth” Orrison, R.N., and William Werner Orrison Sr., M.D., known as Werner. Bill grew up in Minneola, Plains, and Meade, Kans., where his father was among the last generation of country doctors, often making house calls to remote farms, equipped only with the contents of a black bag, sometimes accepting livestock as payment. From his earliest years, Bill witnessed his father’s devotion to humble patients and dreamed of joining him in practice as a medical doctor.

Bill graduated in 1967 from Meade High School, an Eagle Scout and an accomplished trick horseback rider. As a teen, while on a fishing trip with Werner, Bill suffered a freak accident that put him in the first of three near-death states during his life. Bill later described being drawn into a “tunnel of fog” while his father performed an emergency tracheotomy to save his son’s life. Attending the University of Kansas in Lawrence on an ROTC scholarship, Bill rose to commander of his Air Force squadron, but at the Phi Gamma Delta house he was known as “Doc,” for his unlicensed diagnostic skills. After Bill earned the lowest score in the class on his first chemistry test, the professor encouraged him to try another major. By semester’s end, Bill had the highest grade among his peers. He graduated from KU in 1971 and remained a lifelong fan of Jayhawk basketball.

While at KU, Bill attended a talk by the Maharishi Mahesh Yogi, discovering that the hypnosis his father had used on patients in the absence of anesthesia …

AJNR Debuts New Web Site


AJNR has unveiled a brand new Web platform. In addition to the fresh modern design, easier navigation, and improved functionality, the site is now completely mobile-optimized. This eliminates the need for the Journal’s iOS app and at the same time addresses the Android market, which was underserved by the old platform. The new Web site is a major investment in the Journal’s on-line presence. It is built on HighWire Press’s Drupal-based architecture that allows increased capabilities and the flexibility to accommodate new features and changing technology.

Editor-in-Chief Jeffrey Ross shared his enthusiasm for the enhanced experience the new site brings to AJNR’s readers, saying, “We are excited to partner with HighWire and to bring to our readers a modern, responsive AJNR Web site using the JCore platform.  Our readers will find an uncluttered interface, which presents both current and archival content in an easy to access format, with minimal click-through, and that is readily available on whatever device they choose to consume content.”

Dr. Ross selected an Altmetrics tool to analyze article level usage, reach, and social media impact as the first new function added to the site.

Article Level Metrics Product Sheet Final

Annotated Bibliography #15

1. Al-Holou, W. N., Terman, S. W., Kilburg, C., Garton, H. J. L., Muraszko, K. M., Chandler, W. F., Ibrahim, M., et al. (2011). Prevalence and natural history of pineal cysts in adults. J Neurosurg 2011;6:1106-14. doi:10.3171/2011.6.JNS11506

Pineal cysts measuring 5 mm or larger in greatest dimension were found in 478/48,417 patients (1.0%).  Follow up imaging was present in 151 patients for greater than 3 years. The authors conclude that follow-up imaging and neurosurgical evaluation are not mandatory for adults with asymptomatic pineal cysts.

The authors describe the patterns of arterial injury after chiropractic manipulation and their management in the modern endovascular era in 13 patients since 2007.  Of particular note was the severity of the arterial injuries in the cohort. Not only were these lesions often lengthy, their neurological sequelae were frequently severe. Three patients were left permanently debilitated by stroke and 1 died, producing an adverse outcome rate of 31% (4 of 13 patients).

Very complete review of the anatomy and physiology of the intervertebral disc, including over 200 references.  It is amazing to me that we still do not know the precise origin and nature of the cells within the intervertebral disc, or the fate of the notochord cells.
