Use of Metformin and Survival in Patients with Hepatocellular Carcinoma (HCC) Undergoing Liver Directed Therapy: Analysis of a Nationwide Cancer Registry.

Background: Examine the association of metformin use and overall survival (OS) in patients with HCC undergoing image-guided liver-directed therapy (LDT): ablation, transarterial chemoembolization (TACE), or Yttrium-90 radioembolization (Y90 RE).

Methods: Using National Cancer Institute Surveillance, Epidemiology, and End Results registry and Medicare claims databases between 2007 and 2016, we identified patients ≥ 66 years who underwent LDT within 30 days of HCC diagnosis. Patients with liver transplant, surgical resection, and other malignancies were excluded.

Safety and feasibility of a novel bi-directional portal vein access kit during transjugular intrahepatic portosystemic shunt creation.

Background: Transjugular intrahepatic portosystemic shunt (TIPS) creation remains as one of the more technically challenging endovascular procedures. Portal vein access from the hepatic vein often requires multiple needle passes, which increases procedure times, risk of complications, and radiation exposure. With its bi-directional maneuverability, the Scorpion X access kit may be a promising tool for easier portal vein access.

Yttrium-90 Radiation Segmentectomy of Hepatocellular Carcinoma: A Comparative Study of the Effectiveness, Safety, and Dosimetry of Glass-Based versus Resin-Based Microspheres.

Purpose: To evaluate the differences in safety, effectiveness, and dosimetry between glass-based and resin-based ablative yttrium-90 (Y) transarterial radioembolization (TARE) of hepatocellular carcinoma (HCC).

Materials And Methods: Using the modified Response Evaluation Criteria in Solid Tumors and Common Terminology Criteria for Adverse Events, both tumor response and adverse events (AEs) were assessed at 3 months after Y-TARE. Post procedure Y-bremsstrahlung single-photon emission computed tomography/computed tomography voxel-based dosimetry analysis was used to create tumor dose (TD) and normal tissue dose (NTD) volume histograms, and to calculate tumor particle loading and specific activity.

Correlation of Non-tumoral Liver Dose with Treatment-Related Adverse Events in Patients with Hepatocellular Carcinoma Treated with Glass-Based Yttrium-90 Radioembolization.

Purpose: To evaluate the relationship between non-tumor liver (NTL) dose and adverse events (AE) in patients with hepatocellular carcinoma (HCC) treated with glass-based Yttrium-90 radioembolization (Y90-RE).

Materials And Methods: A retrospective analysis of patients with HCC treated with Y90-RE between 2013 and 2018 was performed. Baseline characteristics including demographics and Y90-RE treatment approach were captured.

Surgical resection, radiotherapy and percutaneous thermal ablation for treatment of stage 1 non-small cell lung cancer: protocol for a systematic review and network meta-analysis.

Introduction: Non-small cell lung cancer (NSCLC) makes up the majority of lung cancer cases. Currently, surgical resection is the gold standard of treatment. However, as patients are becoming medically more complex presenting with advanced disease, minimally invasive image-guided percutaneous ablations are gaining popularity.

Endovascular retrieval of an inferior vena cava filter penetrating the false lumen of a chronic aortic dissection, with concomitant iliocaval reconstruction.

Inferior vena cava filter (IVCF) placement is indicated in patients with acute venous thromboembolism who cannot be adequately anticoagulated or have failed anticoagulation. Prompt IVCF retrieval decreases the risk of complications associated with longer dwell times including fracture, penetration, and further thromboembolic events. Endovascular IVCF retrieval has been performed despite penetration into adjacent structures including the aorta; however, penetration into the false lumen of an aortic dissection is rarely seen.

Challenges of Implementing Artificial Intelligence in Interventional Radiology.

Artificial intelligence (AI) and deep learning (DL) remains a hot topic in medicine. DL is a subcategory of machine learning that takes advantage of multiple layers of interconnected neurons capable of analyzing immense amounts of data and "learning" patterns and offering predictions. It appears to be poised to fundamentally transform and help advance the field of diagnostic radiology, as heralded by numerous published use cases and number of FDA-cleared products.

Management of uncomplicated total knee arthroplasty chronic pain and stiffness utilizing cooled radiofrequency ablation: a single institution pilot study.

Objective: The objective of this study is to introduce cooled radiofrequency ablation technical feasibility as an alternative percutaneous image-guided treatment of chronic pain and stiffness in the setting of uncomplicated total knee arthroplasty.

Material And Method: This retrospective pilot study includes a total of 19 consecutive patients experiencing persistent chronic pain after total knee arthroplasty, without underlying hardware complications who had failed conservative care. Patients initially underwent anesthetic blocks of the genicular nerve branches to determine C-RFA candidacy.

Uterine Artery Embolization for Secondary Postpartum Hemorrhage.

Postpartum hemorrhage (PPH) affects approximately 14 million women yearly, accounts for 25% of delivery-related deaths in the world and is the main cause of emergency peripartum hysterectomy. Traditionally, PPH is defined as at least 500 mL of blood loss after vaginal delivery or 1000 mL of blood loss after cesarean-section. However, several authors have suggested a simpler definition to include women who experience hemodynamic instability after birth regardless of amount of blood loss.

Radiology and Political Advocacy: Characterizing Radiology Political Action Committee Donors.

Purpose: To identify factors associated with radiologist donations to radiology political action committees (PACs).

Materials And Methods: A survey was emailed to 4474 radiologists. Factors investigated include demographics, donor history, and knowledge of the federal advocacy process.

Prophylactic absorbable gelatin sponge embolization for angiographically occult splenic hemorrhage.

Nonoperative management of traumatic splenic hemorrhage includes the targeted administration of embolic agents. In certain instances where computed tomography angiography cannot exclude a bleed, prophylactic embolization with absorbable gelatin sponge has been used. In this retrospective case series review, we characterized the demographic data and clinical outcomes associated with 4 patients who underwent prophylactic transarterial splenic artery embolization after blunt abdominal trauma.

Successful sclerotherapy of a recurrent, benign parotid cyst.

Benign parotid lesions can grow to be a cosmetic deformation with psychological sequelae for a patient. Although surgical resection is the treatment of choice, cyst aspiration has also been attempted. This, however, has been shown to recur, requiring repeat intervention.
