3rd Annual University of Wisconsin Interventional Radiology Symposium

The Interventional Radiology Interest Group and UW Department of Radiology hosted the 3rd Annual University of Wisconsin Interventional Radiology Symposium in the Health Sciences Learning Center on January 13. This event featured faculty lecturers from three academic institutions (UW, Medical College of Wisconsin, and Rush University Medical Center), an "interactive" session where medical students gained hands-on experience with common IR procedures and devices, and concluded with a social hour and networking event at Oliver's Public House. The symposium was organized by Sean Golden, a 4th year medical student entering Interventional Radiology, and Dr. Mark Kleedehn.

UW lecturers included Dr. Mark Kleedehn, Dr. Meghan Lubner, and Dr. Orhan Ozkan. Visiting lecturers were Dr. Osmanuddin Ahmed of Rush and Dr. Alexandra Fairchild of MCW. Lecture topics included: 1) IR Training Pathways (including the new IR/DR residency) 2) Ablation 3) Y90 and TACE 4) Musculoskeletal Interventions 5) Peripheral Arterial Disease and 6) Pediatric Interventions.

The "interactive" session featured over a dozen simulators and models from six industry representatives: Boston Scientific, Cook, Terumo, Halyard, Penumbra, and NeuWave. New this year was an endovascular simulator (hosted by Terumo) where students were able to manipulate wires, catheters, and coils under real-time fluoroscopic guidance in a highly realistic computer simulator.

Over 50 medical students were in attendance, including visiting students from Milwaukee, Illinois, and Southern California. A group of visiting students arrived a day early to tour the UW Radiology Department and enjoy dinner with UW students and faculty.

"We hope that this event will expose medical students to the exciting (but often under-publicized) specialty of interventional radiology, and inspire many to pursue a career in this cutting-edge field."

-Sean Golden, 4th Year Medical Student, Symposium Organizer

Congratulations to Meghan Lubner, MD, Associate Professor in the Department of Radiology, for receiving the American Roentgen Ray Society (ARRS) 2018 Melvin M. Figley Fellowship in Radiology Journalism. The fellowship is awarded each year to a practicing radiologist from the U.S. or Canada and offers them the opportunity to work with the American Journal of Roentgenology (AJR) to gain experience in medical journalism over the course of a year.

The Figley fellowship was first awarded in 1990. It was established, according to the ARRS, to “improve the quality of radiology journals by teaching the fundamentals of medical journalism, train manuscript reviewers and future editors, and provide core teachers of medical journalism in radiology departments around the country.” The goal of the fellowship is to “stimulate bright, promising radiologists to continue with an academic career, enhance their credentials, and stimulate interest in good radiology journalism.”

Figley Fellows will receive hands-on experience learning the crafts of medical writing, manuscript preparation, peer review, manuscript editing, the ethics of scientific journalism, and journal publication and printing in personal tutorials given by the AJR editors and editorial and production staff.

Several other members of the UW radiology department have participated in the program in past years including Drs. Mark Kliewer, Jeff Kanne, Donna Blankenbaker, and Perry Pickhardt, who wrote a letter in support of Dr. Lubner’s application.

Radiology Team Hones New Cancer Treatment Focusing on Tumor Ablation

Louis Hinshaw, MD and Paul Laeseke, MD, PhD, of the Abdominal Imaging and Interventional Radiology sections of the Department of Radiology, were featured by the UW Carbone Cancer Center for their instrumental work on microwave tumor ablation. In an article titled, “Heating Up the Fight Against Cancer” in their monthly newsletter, the center discusses the potential shown by tumor ablation and the work of Hinshaw and Laeseke.

A focused therapy called tumor ablation offers a high success rate for eradicating some solid tumors with a low chance of local recurrence – and it does so by killing cancer cells, typically with heat or cold, rather than removing them with surgery or targeting them with harmful chemicals or radiation. Since its inception in the 1990s, researchers at the UW Carbone Cancer Center, including UW radiologists Hinshaw and Laeseke, have been instrumental in the research, development and clinical application of ablation technology, specifically microwave ablation.

Growing Radiology Subspecialty Gives Students Chance to Learn and Interact

The University of Wisconsin School of Medicine and Public Health Department of Radiology recently hosted the Third Annual Interventional Radiology Symposium for Students at the Health Sciences Learning Center on January 13. The event was a joint effort between the UW Department of Radiology and the Interventional Radiology Interest Group to offer interested medical students a chance to learn more about interventional radiology, a rapidly developing subspecialty of radiology.

Over 30 medical students from six different medical schools attended the event, which included faculty lectures and participation in a two-hour hands-on workshop demonstrating interventional radiology techniques. Students travelled from as far as California to attend the symposium, including two students who arrived in Madison a day early to tour the department and meet UW faculty before the symposium. The Department of Radiology’s contribution allowed for the event to be free and to offer a special after-symposium social event at Oliver’s Public House to continue the discussions about interventional radiology.

The program included presentations from UW’s Meghan Lubner, MD, on tumor ablation; Orhan Ozkan, MD, Chief of UW’s IR Section, spoke about catheter-directed therapies for liver cancer; Rush University’s Osmanuddin Ahmed, MD, discussed musculoskeletal interventions; Alexandra Fairchild, MD, from the Medical College of Wisconsin, spoke about peripheral arterial disease; and Mark Kleedehn, MD, of the UW, presented the latest in pediatric interventions and discussed the new IR training pathways.

The hands-on session featured interactive simulators and was sponsored by corporate partners Boston Scientific, Halyard Health, Cook Medical, Terumo Medical Corporation, Penumbra, and NeuWave Medical. The hands-on stations included: a gastrostomy tube exhibit where students learned how to deploy gastropexy T-fasteners in pig stomachs; an ablation station where students microwaved pig livers under ultrasound guidance; and two endovascular computer simulators where students catheterized and stented an atherosclerotic lesion under real-time fluoroscopic guidance.

The event was organized by Sean Golden, a fourth year medical student at UWSMPH pursuing interventional radiology, and Mark Kleedehn, MD, assistant professor in the UW Department of Radiology. Scott Reetz, a first year medical student, and Ryan Valk, a second year medical student, also contributed.

CT Protocol Optimization Project Update

The University of Wisconsin-Madison CT Protocol Optimization Team has been keeping very busy. Not only have we continued to see increased distribution of the UW CT protocols (1,175 GE scanners were shipped with our protocols installed through September 2017), but more importantly, we’re seeing increased utilization. It is still a bit slower than we like, but it’s accelerating.

We are proud to announce that this month a major health care consortium in the South has decided to convert their entire CT operation to the UW protocols. This may be the break we have been waiting for as other large providers will certainly take notice. In this era of cost containment and standardization, our protocols deliver just that, so we hope more organizations will adopt them.

Radiologists, physicists, and technologists, both inside and outside of our organization, have provided their CT expertise and collaboration to identify areas for improvement, and we are happy to declare that many of those improvements were implemented in Version 3.0 of the UW CT protocols, which were submitted to GE in December after extensive validation.

Congratulations to all of us — the CT protocol optimization team; the UW Radiologists (both academic and community), especially the CT section leads; the medical physicists; all of our hardworking technologists and nurses; and the IT support staff. We thank all of you for your constant surveillance of protocol and CT image quality and helping make our protocols so robust. There is nothing else like this on the planet.

It has been a wonderfully fulfilling adventure so far and promises to just keep getting more interesting.

Head and Neck PET/MRI Group Receives 2017 Ride Scholarship

The Head and Neck PET/MRI group at the University of Wisconsin, led by Dr. Greg Avey, has been awarded $50,000 to pursue advances in head and neck cancer imaging by The Ride, a bicycle benefit for cancer research sponsored by the UW Carbone Cancer Center. Three representatives of the PET/MRI group, Drs. Tabby Kennedy, Edward Jackson, and Matt Witek, were recognized during the Wisconsin vs Penn State hockey game earlier this month. The multidisciplinary group is composed of radiation oncologists, radiologists, and medical physicists. The goal of this research group is to find a way to leverage PET/MRI to more accurately stage and efficiently treat head and neck cancer. The group is working to identify imaging markers which predict early tumor response, thus allowing a reduction in radiation dose and a decrease in the long term side effects of radiation treatment. The Ride first began two years ago and has raised more than half a million dollars for cancer research so far. Over 1,250 riders took part September of last year and the event shows even more promise for growth this coming Fall. The mission of the program is to advance state of the art cancer research and treatment to serve cancer patients and families in Wisconsin and beyond. 100% of the money raised by participants goes to funding promising cancer research and treatment opportunities at the University of Wisconsin.

The efforts of associate professors Drs. Elizabeth Sadowski and Jessica Robbins in the assessment of adnexal lesions on ultrasound and MRI have resulted in their appointments to the American College of Radiology (ACR) Women’s Image Panel. Dr. Sadowski has also been appointed to the ACR Ovarian-Adnexal Imaging Reporting and Data System (O-RADS) committee and will chair the ACR O-RADS MRI Educational sub-Committee. The O-RADS MRI lexicon and scoring system has incorporated the work being done here at the UW on MRI characterization of adnexal lesions using the EURAD ADNEx MR Score. Their recent articles on the subject include A systematic approach to adnexal masses discovered on ultrasound: the ADNEx MR scoring system published in the journal Abdominal Radiology, and Complex US adnexal masses during pregnancy: Is pelvic MR imaging accurate for characterization? published in the European Journal of Radiology. Being the only center in the USA to participate in the EURAD ADNEx MR multi-institution trial, UW is a frontrunner in the application of MRI for assessing ovarian lesions and will continue to lead the integration of the ADNEx MR score into the O-RADS MRI lexicon and scoring system.

In addition to their work on MRI of adnexal lesions, Drs. Sadowski and Robbins have also contributed to the development of the Ultrasound O-RADS lexicon and scoring system through leading a multi-institutional study of ultrasound stratification of adnexal cysts. This includes two recent articles published in the journal Radiology, Risk Stratification of Adnexal Cysts and Cystic Masses: Clinical Performance of Society of Radiologists in Ultrasound Guidelines and Indeterminate Adnexal Cysts at US: Prevalence and Characteristics of Ovarian Cancer. Their next endeavor is a multi-institutional analysis of over 700 cysts on ultrasound using the SRU and IOTA imaging based classification systems to determine their performance in identifying ovarian cancers.

The overarching goals of Drs. Sadowski’s and Robbins’ work is to help radiologists identify ovarian cancer on ultrasound and MRI more efficiently so that women with potentially cancerous lesions can be expeditiously treated and to potentially detect ovarian cancers at an earlier stage, when there is hope for a cure.
