Yttrium-90 Radioembolization in the Office-Based Lab.

Purpose: To evaluate the feasibility and benefits of performing yttrium-90 radioembolization in an office-based lab (OBL) compared to a hospital setting.

Materials And Methods: A radioembolization program was established in March 2019 in an OBL that is managed by the radiology department of a tertiary care center. Mapping and treatment angiograms performed in the OBL from March 2019 through January 2020 were compared to mapping and treatment angiograms performed in the hospital during the same time period.

Safety and Effectiveness of Yttrium-90 Radioembolization around the Time of Immune Checkpoint Inhibitors for Unresectable Hepatic Metastases.

Purpose: To assess the safety and effectiveness of yttrium-90 radioembolization and checkpoint inhibitor immunotherapy within a short interval for the treatment of unresectable hepatic metastases.

Materials And Methods: This single-institution retrospective study included 22 patients (12 men; median age, 65 y ± 11) with unresectable hepatic metastases and preserved functional status (Eastern Cooperative Oncology Group performance status 0/1) who received immunotherapy and radioembolization within a 15-month period (median, 63.5 d; interquartile range, 19.

Comparative Analysis of Safety and Efficacy of Transarterial Chemoembolization for the Treatment of Hepatocellular Carcinoma in Patients with and without Pre-Existing Transjugular Intrahepatic Portosystemic Shunts.

Purpose: To compare the safety and efficacy of transarterial chemoembolization for hepatocellular carcinoma (HCC) in patients with and without transjugular intrahepatic portosystemic shunts (TIPS).

Materials And Methods: This single-institution study included a retrospective review of 50 patients who underwent transarterial chemoembolization for HCC between January 2010 and April 2017. Twenty-five patients had preexisting TIPS, and 25 patients were selected to control for age, sex, and target tumor size.

A Descriptive Revenue Analysis of a Wound-Center IR Collaboration to Treat Lower Extremity Venous Ulcers.

Purpose: To describe the revenue from a collaboration between a dedicated wound care center and an interventional radiology (IR) practice for venous leg ulcer (VLU) management at a tertiary care center.

Materials And Methods: This retrospective study included 36 patients with VLU referred from a wound care center to an IR division during the 10-month active study period (April 2017 to January 2018) with a 6-month surveillance period (January 2018 to June 2018). A total of 15 patients underwent endovascular therapy (intervention group), whereas 21 patients did not (nonintervention group).

Interventional Radiology Suite: A Primer for Trainees.

Familiarity with different instruments and understanding the basics of image guidance techniques are essential for interventional radiology trainees. However, there are no structured references in the literature, and trainees are left to "pick it up as they go". Puncture needles, guidewires, sheath systems, and catheters represent some of the most commonly used daily instruments by interventional radiologists.

Analysis of Preoperative Portal Vein Embolization Outcomes in Patients with Hepatocellular Carcinoma: A Single-Center Experience.

Purpose: To analyze outcomes of patients with hepatocellular carcinoma (HCC) undergoing preoperative portal vein embolization (PVE).

Materials And Methods: A retrospective analysis of survival, recurrence, and complications was performed in 82 patients with HCC undergoing preoperative PVE and surgical treatment with curative intention from June 2006 to December 2014.

Results: Rate of major adverse events after PVE was 11% with no mortality.

Portal vein embolization before right hepatectomy or extended right hepatectomy using sodium tetradecyl sulfate foam: technique and initial results.

Purpose: To evaluate the safety and efficacy of portal vein embolization (PVE) with sodium tetradecyl sulfate (STS) foam.

Materials And Methods: A single-center retrospective review of 35 patients (27 men and 8 women; mean age, 61 y) who underwent PVE with STS foam was performed. The technical success rate, rate of PVE at producing adequate future liver remnant (FLR) hypertrophy, and rate of disease progression precluding resection after PVE were analyzed.

Percutaneous microwave ablation of renal tumors using a gas-cooled 2.4-GHz probe: technique and initial results.

The feasibility, safety, and preliminary effectiveness of microwave ablation (MWA) in the treatment of renal tumors using a high-powered, carbon dioxide-cooled probe were evaluated. There were 15 tumors treated in 14 patients. Computed tomography was performed immediately after MWA, and follow-up imaging was performed to evaluate for recurrence.

Utility of quantitative MRI metrics for assessment of stage and grade of urothelial carcinoma of the bladder: preliminary results.

Objective: The purpose of this study was to assess associations between quantitative MRI metrics and pathologic indicators of aggressiveness of urothelial carcinoma of the bladder.

Materials And Methods: In this retrospective biinstitutional study, 37 patients (28 men and nine women; mean age, 73 ± 12 years) who underwent pelvic MRI including diffusion-weighted imaging (b values 0, 400, and 800 s/mm(2)) and T2-weighted imaging before transurethral resection or cystectomy for urothelial carcinoma of the bladder were identified. Tumor diameter (measured on T2-weighted imaging), normalized T2 signal intensity (to muscle; hereafter labeled normalized T2) and apparent diffusion coefficient (ADC) were measured for all tumors.
