Abstract No. 6 Deep Learning Diagnosis of Femoropopliteal Artery Stenosis Using MIP Images from CT Angiography
https://www.jvir.org/article/S1051-0443(24)00822-4/fulltext?rss=yes

Peripheral arterial occlusive disease (PAOD) can be diagnosed using lower extremity computed tomography angiography (CTA), assessing stenosis in arteries of lower extremities. We aimed to develop and evaluate a deep learning-based detection algorithm for the preliminary screening and interpretation of significant stenosis in the lower extremity arteries, with a focus on the femoropopliteal artery, based on maximum intensity projection (MIP) images of lower extremity CTA in patients with PAOD.

Abstract No. 4 ▪ ABSTRACT OF THE YEAR Preliminary Results of the FRONTIER Trial: Safety and Feasibility of Yttrium-90 TheraSphere in Recurrent Glioblastoma
https://www.jvir.org/article/S1051-0443(24)00819-4/fulltext?rss=yes

Glioblastoma (GBM) is a highly aggressive brain tumor with poor prognosis, particularly in recurrent cases where treatments are limited. Yttrium-90 (Y90) microsphere therapy, successfully used for hepatic malignancies, offers the potential for targeted radiation in GBM. The FRONTIER trial evaluates the safety and feasibility of TheraSphere GBM Y90-microsphere treatment, in patients with recurrent GBM.

Abstract No. 3 ▪ ABSTRACT OF THE YEAR One-Year Clinical and Lifetime Cost-Effectiveness Outcomes of Transcatheter Arterialization for No-Option CLTI in the U.S.
https://www.jvir.org/article/S1051-0443(24)00818-2/fulltext?rss=yes

Patients with chronic limb-threatening ischemia (CLTI) present with non-healing ischemic ulcers, gangrene, or both. Up to 20% of these patients are considered “no-option” because they are ineligible for conventional open or endovascular treatment options and are at a high risk for major amputation. Recently, transcatheter arterialization of the deep veins (TADV) has demonstrated positive outcomes in this challenging population. We compare clinical and economic outcomes in a pooled cohort of TADV patients treated with the LimFlow System (Inari Medical, Irvine, CA, USA) in PROMISE I and II versus patients from the concurrent CLariTI natural history registry, using propensity-score matching.

Abstract No. 2 ▪ ABSTRACT OF THE YEAR Initial Experience of robotic-Assisted Ablation: A Rapid Learning Curve Leads to Shorter Procedures with Less Needle Repositioning
https://www.jvir.org/article/S1051-0443(24)00817-0/fulltext?rss=yes

Stereotactic guidance for abdominal ablations has shown promise for faster and more accurate probe placement. This can be combined with robotic assistance for more precise probe placement, particularly with multi-needle and off-plane trajectories. The aim of this project was to describe an initial experience with robotic-assisted percutaneous ablations of abdominal lesions.

Abstract No. 95 Deep Learning Prediction of MRI Data for Evaluating Combined Transcatheter NK Cell Local Delivery and Sorafenib Therapy in Hepatocellular Carcinoma
https://www.jvir.org/article/S1051-0443(24)00920-5/fulltext?rss=yes

Accurate early assessment of treatment responses in hepatocellular carcinoma (HCC) post-NK cell therapy is complicated by pseudoprogression, presenting a significant clinical challenge. This study aims to compare deep learning and traditional radiomics approaches to precise evaluation of HCC treatment outcomes following combined intraarterial transcatheter NK cell delivery and Sorafenib administration, demonstrating the superior ability of deep learning models in capturing nuanced texture features from MRI images that are invisible to the naked eye.

Abstract No. 8 Mechanical Aspiration Thrombectomy in the Treatment of Acute Limb Ischemia: A Real-World Single-Center Safety and Efficacy Analysis
https://www.jvir.org/article/S1051-0443(24)00824-8/fulltext?rss=yes

Acute limb ischemia (ALI) is characterized by sudden reduction in limb perfusion and is associated with high one-year mortality (15%–20%) and limb amputation (10%–15%) rates despite timely intervention. No evidence exists favoring initial thrombolysis or surgery as preferred options for treatment when comparing limb salvage, amputation, or death at 30-day, six-month, and one-year intervals. Advancements in endovascular techniques, particularly the use of mechanical aspiration thrombectomy, have shown promise in improving outcomes, including restoration of flow and limb salvage, for patients with ALI.

Self-Reported Health Status Survey Creation and Distribution Outcomes in a Large Cohort of Pediatric Oncology Patients Treated with Proton Radiotherapy
https://www.advancesradonc.org/article/S2452-1094(25)00036-3/fulltext?rss=yes

Most pediatric patients receiving radiotherapy (RT) at XXXX are referred from outside institutions and later return to their original care providers. As quaternary care centers, proton therapy centers face unique challenges in tracking patient follow-up, yet obtaining longitudinal data is crucial for assessing RT outcomes. We implemented an annual direct-to-patient survey to improve follow-up data collection.
