    Abstract Objective: To assess the #Radiology conversation on Twitter social media platform during the COVID-19 pandemic.
    Materials and methods: From February 1 to December 31, 2020, all tweets with a #Radiology hashtag were identified using the healthcare social media analytics tool, Symplur Signals. Data collected included number of tweets, retweets, impressions, links, and user characteristics. Data were stratified by the presence of a COVID-19-related keyword, and a social media network analysis was further performed.
    Results: Of the 68,172 tweets, 10,093 contained COVID-19 content from 2809 users generating 65,513,669 impressions. More tweets with COVID-19 content contained links than without (P < 0.01). Network analysis demonstrated most users were physicians (48.10%), authoring the most tweets (40.38%), using the most mentions (32.15%), and retweeting the most (51.45%). The most impressions, however, were by healthcare organizations not providing clinical care (20,235,547 impressions, 30.89%). Users came from 80 countries, most from the United States (29.3%) and the United Kingdom (8.69%). During early March, COVID-19 dominated the #Radiology conversation, making up 54.67% of tweets the week of March 14 and 64.74% of impressions the week of March 21 compared to 13.97% of tweets and 16.76% of impressions in the remainder of the study period (P < 0.01).There was an influx of new users to the #Radiology conversation during this time period with more users tweeting about COVID-19 than not (P < 0.01).
    Conclusion: Discussion of COVID-19 in the #Radiology community increased significantly during the early weeks of the pandemic. Real time sharing and collaboration proved a useful tool when rapid information dissemination was needed to manage an emerging pathogen.

    Abstract Inferior vena cava thrombosis (IVCT) is a rare but severe disease that is associated with a high rate of mortality. IVCT can be categorized into primary versus secondary thrombosis dependent upon the underlying pathophysiology. The diagnosis includes both clinical probability assessment as well as the imaging evaluation. The optimal therapeutic strategy remains the target of continued research. Although anticoagulation therapy remains fundamental in treating IVCT, its inherent limitations have led to the use of minimally invasive, endovascular treatment options, including transcatheter thrombolysis, mechanical thrombectomy or a combination of these techniques. This review focuses on the etiology, diagnostic assessment, and endovascular treatment options for IVCT.

    Abstract Purpose: To evaluate primary care provider awareness of interventional radiology (IR) services at a tertiary care academic medical center to identify areas of IR practice that require additional education and awareness initiatives.
    Material and methods: An internet-based survey was distributed via email to primary care providers, including internal medicine (IM), family medicine (FM), obstetrics and gynecology (OBGYN), and hospital medicine (HM) physicians in the region. The survey consisted of 17 questions regarding provider demographics, experiences with IR in their practice, awareness of IR training, and awareness of IR procedures and services.
    Results: A total of 234 of 533 invited physicians completed the survey (40% IM, 22% FM, 22% HM, and 16% OBGYN). Providers rated their knowledge of IR as poor (49, 20.3%), adequate (137, 56.9%), good (49, 20.3%), and excellent (6, 2.5%). Although 235 (97.5%) had consulted IR previously, only 141 (58.5%) had referred a patient directly to IR for an elective procedure. IR was offered as an alternative to surgical procedures never (42, 17.6%), a quarter of the time (101, 42.3%), half of the time (61, 25.5%), three-quarters of the time (27, 11.3%), and every time (8, 3.35%). Most respondents (161, 67.4%) learned the most about IR procedures during residency. Most (180, 75.3%) indicated that they would like to learn more about IR.
    Conclusions: These findings indicate that more can be done to educate providers about the potential role of IR in patient care. Provider awareness is limited regarding procedures that are increasingly popular in the IR community. This study helps to identify specific areas of IR in which awareness of can be increased.

    Abstract Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and third leading cause of cancer-related mortality worldwide. While surgical resection and transplantation are the standard first-line treatments for early-stage HCC, most patients do not fulfill criteria for surgery. Fortunately, catheter-directed and percutaneous locoregional approaches have evolved as major treatment modalities for unresectable HCC. Improved outcomes have been achieved with novel techniques which can be employed for diverse applications ranging from curative-intent for small localized tumors, to downstaging or bridging to resection and transplantation for early and intermediate disease, and locoregional control and palliation for advanced disease. This review explores recent advances in liver-directed techniques for HCC including bland transarterial embolization, chemoembolization, radioembolization, and ablative therapies, with a focus on patient selection, procedural technique, periprocedural management, and outcomes.

    Abstract Objective: The objective of this study was to evaluate complications of Greenfield (Boston Scientific, Marlborough, Mass) stainless steel inferior vena cava (IVC) filters on follow-up computed tomography (CT) imaging and to elucidate associated risk factors.
    Methods: Ninety-three patients with CT studies obtained for other reasons after Greenfield IVC filter placement (2007-2014) were retrospectively studied. Greenfield filters were placed permanently in those with venous thromboembolism and an expected lifelong contraindication to anticoagulation or life expectancy <6 months. Patients' demographic data, procedural characteristics, and imaging studies were reviewed and factors associated with perforation rates were analyzed.
    Results: A total of 190 follow-up CT imaging studies were available for review. In total, filter-associated IVC thrombus (n = 10 [10.7%]) and pulmonary embolism breakthrough (n = 4 [4.3%)] were documented by contrast-enhanced CT. Perforation was evident in 18 patients (19.4%) with an average indwelling time of 256 days. No symptomatic perforation and no strut fracture were documented. There was no significant difference in perforation rate with respect to age of the patient (P = .61), sex (P = 1.00), or history of malignant disease (P = .40). The filter perforation rate and number of perforating struts were significantly higher in patients with longer indwelling time (>90 days) than in patients with shorter indwelling time (<90 days; P < .01). Caval cross-sectional areas of patients who experienced IVC filter perforations at >90 days were significantly smaller than those of nonperforated patients (284 vs 358 mm
    Conclusions: Stainless steel Greenfield filters remain a relatively safe option for patients requiring permanent mechanical filtration.

    Abstract Quality improvement (QI) initiatives have benefited patients as well as the broader practice of medicine. Large-scale QI has been facilitated by multi-institutional data registries, many of which were formed out of national or international medical society initiatives. With broad participation, QI registries have provided benefits that include but are not limited to establishing treatment guidelines, facilitating research related to uncommon procedures and conditions, and demonstrating the fiscal and clinical value of procedures for both medical providers and health systems. Because of the benefits offered by these databases, Society of Interventional Radiology (SIR) and SIR Foundation have committed to the development of an interventional radiology (IR) clinical data registry known as VIRTEX. A large IR database with participation from a multitude of practice environments has the potential to have a significant positive impact on the specialty through data-driven advances in patient safety and outcomes, clinical research, and reimbursement. This article reviews the current landscape of societal QI programs, presents a vision for a large-scale IR clinical data registry supported by SIR, and discusses the anticipated results that such a framework can produce.

    Abstract Purpose: To evaluate national trends in tube-related genitourinary interventions, with specific attention to primary operator specialty.
    Methods: Using a 5% national sample of Medicare claims data from 2005 to 2015, all claims associated with nephrostomy tube, nephro-ureteral tube, and ureteral stent placement and exchange were identified. The annual volume of the nine billable procedures were analyzed to evaluate trends in the number of procedures performed and primary operator specialty over time. The Charleston Comorbidity Index (CCI) was used to evaluate patient comorbidities and to determine differences in patient populations treated by interventional radiologists and urologists.
    Results: The total volume of tube-related genitourinary interventions has increased over the course of the study period, representing 455.0 services per 100,000 Medicare Fee-for-Service beneficiaries in 2005 to 607.2 services in 2015, an increase of 33.4%. Interventional radiologists performed the majority of all procedures in all procedure types and for each year (>90%) with the exception of nephro-ureteral catheter placement or ureteral stent placement, for which urologists performed the overwhelming majority of procedures each year (>85%). Interventional radiologists performed 63% of their total number of procedures on patients with a CCI = 3 or higher, and urologists performed 42% of their total number of procedures on patients with a CCI = 3 or higher (P < .01).
    Conclusion: Tube-related genitourinary interventions have demonstrated persistent growth over the 2005 to 2015 decade. Interventional radiologists are the dominant providers for the majority of these interventions compared with urologists while delivering care to a patient population with a higher number of comorbidities.

    Abstract Intravascular ultrasound (IVUS) is a proven and rapidly developing imaging modality that can be used for a multitude of both diagnostic and interventional purposes. By allowing for superior intraluminal characterization, compared with angiography, IVUS has emerged as a technically valuable tool in interventional procedures such as transjugular intrahepatic portosystemic shunt/direct intrahepatic portosystemic shunt, venous interventions (May Thurner stenting, inferior vena cava filter placement, recanalization in the setting of chronic venous thrombosis/insufficiency), percutaneous fenestration in the setting of aortic dissection and angioplasty. Additional applications evaluating coronary arteries and plaque morphology have been described, but are outside the scope of this review. In addition to IVUS's merit as a pre- and intra-procedural guidance modality, there are also several advantages compared to the gold standard of angiography which include decreased need for iodinated contrast, decreased radiation exposure and decreased procedural times in certain cases. With current research, such as that aimed at supraharmonic imaging, further improvements in imaging depth, resolution and contrast to noise ratio are on the horizon.

    Abstract Purpose: This study evaluates the selection, use, and risks of permanent and retrievable inferior vena cava filters (IVCFs) in patients who have undergone organ transplantation.
    Materials and methods: Single-center retrospective review of 35 patients who had an IVCF placed following organ transplantation. Patient demographics, IVCF indication, and eligibility for retrieval were reviewed. Computed tomography (CT) studies showing the filter (n=22) were evaluated independently for IVCF adverse effects.
    Results: Thirty-two (91%) of 35 patients had retrievable IVCFs placed while three (9%) patients received permanent IVCFs. Filter retrieval was indicated in three of the 32 patients receiving retrievable filters and was performed in two cases. Patients were ineligible for retrieval due to short life expectancy, complications/contraindications to anticoagulation, extended filter dwell time, lost to follow-up, and undetermined therapeutic value of anticoagulation.
    Conclusion: Current practices of filter placement usually dictate placing a retrievable IVCF in transplant patients. However, transplant patients are unlikely to be eligible for filter retrieval especially in situations of advanced age and comorbidities. Given the low incidence of eligibility for retrieval in this patient population, these results suggest preferential placement of permanent filters may reduce the potential morbidity due to filter-related complications, such as strut perforation, in transplant patients.
