OBJECTIVES: The purpose of this study is to provide expert consensus recommendations to establish a global ultrasound curriculum for undergraduate medical students.

METHODS: 64 multi-disciplinary ultrasound experts from 16 countries, 50 multi-disciplinary ultrasound consultants, and 21 medical students and residents contributed to these recommendations. A modified Delphi consensus method was used that included a systematic literature search, evaluation of the quality of literature by the GRADE system, and the RAND appropriateness method for panel judgment and consensus decisions. The process included four in-person international discussion sessions and two rounds of online voting.

RESULTS: A total of 332 consensus conference statements …

Making Waves: How Ultrasound-Targeted Drug Delivery Is Changing Pharmaceutical Approaches., Lauren J Delaney, Selin Isguven, John R Eisenbrey, Noreen J Hickok, Flemming Forsberg

Department of Radiology Faculty Papers

Administration of drugs through oral and intravenous routes is a mainstay of modern medicine, but this approach suffers from limitations associated with off-target side effects and narrow therapeutic windows. It is often apparent that a controlled delivery of drugs, either localized to a specific site or during a specific time, can increase efficacy and bypass problems with systemic toxicity and insufficient local availability. To overcome some of these issues, local delivery systems have been devised, but most are still restricted in terms of elution kinetics, duration, and temporal control. Ultrasound-targeted drug delivery offers a powerful approach to increase delivery, therapeutic …

Point-Of-Care Ultrasound: New Concepts And Future Trends, Yaoting Wang, Huihui Chai, Ruizhong Ye, Jingzhi Li, Ji-Bin Liu, Chen Lin, Chengzhong Peng

Department of Radiology Faculty Papers

Ultrasound (US) technology, with major advances and new developments, has become an essential and first-line imaging modality for clinical diagnosis and interventional treatment. US imaging has evolved from one-dimensional, twodimensional to three-dimensional display, and from static to real-time imaging, as well as from structural to functional imaging. Based on its portability and advanced digital imaging technique, US was first adopted by emergency medicine in the 1980s and gradually gained popularity among other specialists for clinical diagnosis and interventional treatment. Point-of-Care Ultrasound (POCUS) was then proposed as a new concept and developed for new uses, which greatly extended clinical US applications. …

The spread of new coronavirus (SARS-Cov-2) follows a different pattern than previous respiratory viruses, posing a serious public health risk worldwide. World Health Organization (WHO) named the disease as COVID-19 and declared it a pandemic. COVID-19 is characterized by highly contagious nature, rapid transmission, swift clinical course, profound worldwide impact, and high mortality among critically ill patients. Chest X-ray, computerized tomography (CT), and ultrasound are commonly used imaging modalities. Among them, ultrasound, due to its portability and non-invasiveness, can be easily moved to the bedside for examination at any time. In addition, with use of 4G or 5G networks, remote …

Extra-Articular Synovial Chondromatosis Of The Ankle: Unusual Case With Radiologic-Pathologic Correlation., Sachin Dheer, Paul E Sullivan, Faith Schick, Homyar Karanjia, Nicholas Taweel, John Abraham, Wei Jiang

Department of Radiology Faculty Papers

Extra-articular synovial chondromatosis is a rare entity in the foot and ankle. We present a case of a 49-year-old female who presented for evaluation of a palpable concern following trauma; which was found to represent synovial chondromatosis. This case demonstrates the multimodality imaging findings, including ultrasound and MRI, with histopathologic correlation.

Cmut/Cmos-Based Butterfly Iq – A Portable Personal Sonoscope, Joyce Liu, Ba, Jiajun Xu, Md, Flemming Forsberg, Phd, Faium, Ji-Bin Liu, Md

Department of Radiology Faculty Papers

With the development of bioengineering technologies, medical ultrasound systems have evolved and advanced over the years, including the transition of ultrasound machines from analog devices to digital systems and improvements in transducer assembly from piezoelectric ceramics to single crystals. In the past several years, the further miniaturization of ultrasound units has become possible with the advancement of computer chip manufacturing and production. Most recently, a new handheld ultrasound system has been developed by the startup company Butterfly Network, using an innovative CMUT/CMOS-based probe technique. This paper will review the history, technology and features of this new device, as well as …

Structural Changes In Glaucoma: A Volumetric Mri Study, John Lackey, Alice L. Williams, Srinivas Gatla, Sheryl S. Wizov, Thomas Chia, George Spaeth, Song Lai

Department of Radiology Faculty Papers

Purpose: To investigate brain structural changes in patients with glaucoma.

Methods: High resolution 3D T1-weighted MP-RAGE MRI images were collected in 11 glaucoma patients (5 female, 6 male, 65+/-11 yrs), and 11 age- and gender-matched controls (64+/-12 yrs). The images were first analyzed using an automatic voxel-based morphometry technique which combines a fully automated spatial normalization approach, dubbed HAMMER [1], in conjunction with a tissue mass preserving framework called RAVENS [2]. Four consecutive steps were carried out: removal of non-brain voxels, tissue segmentation, spatial normalization to a standardized template, and generation of a mass-preserving tissue density map (i.e. RAVENS map) …

Dramatically Increased Musculoskeletal Ultrasound Utilization From 2000 To 2009, Especially By Podiatrists In Private Offices, Richard E. Sharpe, Levon N. Nazarian, Laurence Parker, Vijay Rao, David C. Levin

Department of Radiology Faculty Papers

PURPOSE: Over the past two decades, musculoskeletal (MSK) ultrasound has emerged as an effective means of diagnosing MSK pathologies. However, some insurance providers have expressed concern about increased MSK ultrasound utilization, possibly facilitated by the low cost and ready availability of ultrasound technology. The purpose of this study was to document trends in MSK ultrasound utilization from 2000 to 2009 within the Medicare population.

METHODS: Source data were obtained from the CMS Physician/Supplier Procedure Summary Master Files from 2000 to 2009, and records were extracted for procedures for extremity nonvascular ultrasound. We analyzed annual volume by provider type using specialties, …
