ASNR Introduces Study Groups & Workshops at ASNR 2014

ASNR introduces the Study Groups.The study groups target areas of critical importance to the field of Neuroradiology and are composed of neuroradiologists, neuroscientists, and investigators from associated disciplines, who are united in their interest in higher level, sophisticated investigations of these target areas. The target areas that have been selected are cerebrospinal fluid flow, tumor genomics, vessel wall imaging, and the clinical translation of fMRI and DTI. These four study groups will present their work to date at an ASNR session on Tuesday, May 20. In addition, they will have working meetings on either Wednesday, May 21 evening or on Friday, May 23.

ASNR introduces the fMRI Workshops. The workshops are intended to provide a hands-on experience that allows participants to translate knowledge learned at the ASNR meeting into direct experience that will enable them to perform these studies when they return to their practices. There will be two workshops, one that is intended for novices and that is more practical and clinically oriented on Saturday, May 17 and Sunday, May 18 and one that is aimed at more beginner to intermediate practitioners who are interested in pursuing in-depth clinical BOLD fMRI pre-surgical brain mapping applications on Thursday, May 22.

ASNR introduces the TBI Workshop. The American Society of Neuroradiology, the ACR Head Injury Institute, the American Society of Functional Neuroradiology, and the ASNR Clinical Translation of Functional and Diffusion Magnetic Resonance Imaging (MRI) Study Group, will hold a TBI workshop on Friday May 23, the day after the ASNR meeting, in Montreal, Canada. The goal of this workshop is to brainstorm on issues related to and develop consensus recommendations in terms of creating a well-characterized normative database of comprehensive imaging and ancillary data to serve as a reference for tools that will allow interpretation of advanced neuroimaging tests at an individual TBI patient level. Of important note, this workshop will NOT include any educational sessions or lectures.

No CME credit will be awarded for the Study Groups or Workshops

1) Practical fMRI and Diffusion Tractography (Hands-on Workshop)

Saturday, May 17, 2014, 1:00pm - 5:00pm
Sunday, May 18, 2014, 8:00am - 5:00pm

During most MRI procedures, there is no need for interaction between the administrator of the test and the patient. The situation is quite the opposite in functional MRI (fMRI), where the neurological status of the patient must be assessed; an appropriate paradigm must be selected based on the neurological assessment and prior MRI examinations. Further, the paradigm must be delivered to and successfully performed by the patient while in the MRI machine. In addition, there is a rather complicated analysis of the fMRI and diffusion tractography data, which must be performed and assessed. How to properly perform these tasks is often not addressed during residency and fellowship training or in annual scientific society meetings.

2) Imaging Genomics Study Group

Wednesday, May 21, 2014, 6:30pm - 8:00pm
The ASNR Imaging Genomics Study Group serves as a unified voice and body towards advancing the clinical and research field of imaging genomics. Towards this mission, this study group is working on the development and validation of imaging genomics biomarkers and biomarker signatures. They will be opening an Image-Guided, Image-Registered (IGIR) Stereotactic Brain Biopsy Multi-center Clinical Trial that seeks to validate imaging genomics and subsequently metabolomics and proteomics using standardized IGIR biopsies, imaging protocols, and genomic collection and analysis. They are also focusing on need for standardization of imaging across the vendors, software platforms, post-processing techniques, among others and to enhance awareness and multidisciplinary collaboration among the imaging and non-imaging communities to strengthen imaging and imaging's presence within these fields. The ASNR Imaging Genomics Study Group will also publish the ASNR Imaging Genomics White Paper regarding the current state and future directions of imaging genomics in brain tumors.

3) Clinical Translation of Functional and Diffusion MRI Study Group

Wednesday, May 21, 2014, 6:30pm - 8:00pm
The Clinical Translation of Functional and Diffusion Magnetic Resonance Imaging (MRI) represents an international multidisciplinary endeavor to identify critical knowledge gaps that must be addressed to translate fMRI and diffusion imaging techniques into sensitive and specific neuroimaging tools for the diagnosis and prognostication of central nervous system disease. Comprised of representatives from neuroradiology, neurology, neurosurgery, psychiatry, pediatrics, and the neurosciences, study group members will leverage their broad perspective to develop a strategic framework of key action items to address these knowledge gaps. The study group has recently partnered with the Quantitative Imaging Biomarkers Alliance (QIBA) of the Radiological Society of North America, as well as the Research Committee of the American College of Radiology Head Trauma Institute to conduct multi-center reproducibility studies of specific fMRI and diffusion imaging techniques. The study group has also begun to develop a series of white papers to review the evidence supporting the use of these advanced neuroimaging techniques in clinical practice. Additional manuscripts are also being developed to review the methodological breadth of diffusion imaging and evidence supporting the clinical utility of diffusion imaging, as applied to a single clinical entity (e.g., traumatic brain injury, preterm birth, brain tumors, multiple sclerosis, etc). By disseminating the findings, conclusions, and consensus of the study group, we hope to ultimately advance the diagnostic capability of functional and diffusion MRI to improve the lives of the patients we serve.

4) Intracranial and Cervical Vessel Wall Imaging Study Group

Wednesday, May 21, 2014, 6:30pm - 8:00pm
With the recent success of high-resolution cervical vessel wall imaging for defining stroke risk beyond that achievable by angiography, we have now turned our attention to the intracranial vessel wall, a new frontier in neurovascular imaging. Recognizing this, the ASNR has supported the formation of a vessel wall imaging study group mandated to take a leading role in advancing both clinical applications and research in this new and growing field. The group is composed of a multidisciplinary team organized to develop methodologies and share clinical expertise for redefining our knowledge of both cervical and intracranial vasculopathies. Our primary goals are to establish uniform imaging protocols, promote multi-institutional research, and develop educational programs and materials. Since the effort is just beginning, there is a tremendous opportunity for making seminal and impactful contributions in this field.

5) Beginner to Intermediate BOLD Functional MRI (Hands-on Workshop)

Thursday, May 22, 2014, 10:00am - 5:00pm
This workshop will provide a practical step-by-step post-processing of clinical BOLD fMRI pre-surgical brain mapping of eloquent corteses with SPM8 software and data presentation. This activity is intended to educate neuroradiologists, neuroradiology fellows, physicists, clinical psychologists and MR technologists. The workshop is intended for those with beginner to intermediate level of fMRI experience.
Attendees should, at the completion of this workshop, be able to perform the following:

  • Preprocessing of BOLD fMRI-Realignment/Coregistration, Spatial Normalization, Smoothing
  • Single Subject Analysis-Model Specification, Model Estimation, and Visualization of the BOLD data

Registrations are required to bring to the workshop their own laptop with a minimum 2G of RAM and 10G of hard disk space. The machines should have preloaded SPM8 and MATLAB software prior to the workshop. DICOM BOLD fMRI practice data sets will be available at the workshop. All registrants will be given instructions on downloading SPM8 and the 15-day free MATLAB license prior to the workshop.


6) Hydrocephalus and CSF Flow Group/IHIWG

Program Schedule (as of 5/19/2014)

Thursday, May 22, 2014, 11:00am - 5:00pm
Friday, May 23, 2014,  8:00am – 5:00pm

The IHIWG (International Hydrocephalus Imaging Working Group (www.IHIWG.org) consists of neuroradiologists, neurologists, neurosurgeons, bioengineers, and basic scientists who meet twice a year in conjunction with ASNR and ISHCSF (International Society for Hydrocephalus and CSF Disorders). This year we will start with a two hour discussion of the Glymphatic system. Subsequently we will address all forms of hydrocephalus including DESH (Disproportionately Enlarged Subarachnoid Space Hydrocephalus) with emphasis on imaging NPH. We discuss phase contrast and TimeSLIP techniques to measure CSF motion in various disease states. We review CSF production and resorption, role of aquaporins, and CSF flow measurements to study Chiari I malformations as well as potential sources of error in our measurements.

We discuss infantile hydrocephalus and benign external hydrocephalus and the role of the latter as a potential cause of NPH later in life. We examine changes in DTI and MR elastography in NPH and discuss related topics such as aqueductal stenosis and pseudotumor cerebri. We debate the value of imaging vs. detailed clinical assessment vs. a high volume tap test vs. saline infusion tests to select NPH patients for shunting.


7) Joint ASNR-ACR HII-ASFNR TBI Workshop: Bringing Advanced Neuroimaging for TBI into the Clinic

Friday, May 23, 2014, 8:00am - 5:00pm
The past decade has seen impressive advances in the types of neuroimaging information that can be acquired in patients with traumatic brain injury (TBI). Available techniques now allow us to infer the presence of microscopic changes occurring in white and gray matter, along with alterations in physiology and function. Unfortunately, many of these approaches remain confined to population-based research, particularly in mild to moderate TBI. There is a need for developing patient-centered tools and bringing advanced neuroimaging tools into the clinic as a priority. The greatest limitation to the development of these tools to date is the lack of age-stratified, sequence-specific values across a neurologically normal population. This requirement is comparable to that imposed on other diagnostics in clinical medicine such as hematocrit or troponin values, where the variations of normal must be established to determine the operating parameters of the test prior to its utilization in a clinical setting. Armed with a clear understanding for the normal variation of voxels or ROIs across a population in a sequence-specific fashion, computational tools may developed for the patient-based interpretation of advanced neuroimaging studies in the clinical setting.
Such approaches would be based upon a machine learning/random forest approach for the identification of abnormal patterns that would be established by the utilization of training data from TBI patients compared against a well-characterized normal standard.

The American Society of Neuroradiology, the ACR Head Injury Institute, the American Society of Functional Neuroradiology, and the ASNR Clinical Translation of Functional and Diffusion Magnetic Resonance Imaging (MRI) Study Group, will hold a TBI workshop on Friday May 23, the day after the ASNR meeting, in Montreal, Canada. The goal of this workshop is to brainstorm on issues related to and develop consensus recommendations in terms of creating a well-characterized normative database of comprehensive imaging and ancillary data to serve as a reference for tools that will allow interpretation of advanced neuroimaging tests at an individual TBI patient level. Of important note, this workshop will NOT include any educational sessions or lectures.
