Safety and efficacy of repeat Y90 radioembolization to the same hepatic arterial territory.

Objective: To study the efficacy and safety of repeat transarterial radioembolization (TARE) to similar hepatic arterial territories.

Methods: Between 3/2011 and 4/2019, 26 patients (25 males and 1 Female, Mean Age: 65 yo, SD: 11.7 yo, Range: 18-83.

Lung and Abdominal Biopsies in the Age of Precision Medicine.

Image-guided percutaneous needle biopsies (PNBs) are one of the most common procedures performed in radiology departments today. Rapid developments in precision medicine, which identifies molecular and genomic biomarkers in cancers, have ushered a new paradigm of oncologic workup and treatment. PNB has conventionally been used to establish a benign or malignant nature of a lesion during initial diagnosis or in suspected metastatic or recurrent disease.

Inability of conventional imaging findings to predict response to laparoscopic release of the median arcuate ligament in patients with celiac artery compression.

Objective: The objective of this study was to identify duplex ultrasound (DUS) or computed tomography angiography (CTA) imaging findings that can predict clinical response to laparoscopic release of the median arcuate ligament (MAL) in patients with celiac artery compression.

Methods: There were 299 patients who were evaluated for MAL syndrome (MALS) between January 2009 and November 2015. Of these, 29 underwent laparoscopic MAL release and completed 1-year follow-up.

Comparison between whole-body and head and neck neurovascular coils for 3-T magnetic resonance proton resonance frequency shift thermography guidance in the head and neck region.

The purpose of this study is to compare the image quality of magnetic resonance (MR) treatment planning images and proton resonance frequency (PRF) shift thermography images and inform coil selection for MR-guided laser ablation of tumors in the head and neck region. Laser ablation was performed on an agar phantom and monitored via MR PRF shift thermography on a 3-T scanner, following acquisition of T1-weighted (T1W) planning images. PRF shift thermography images and T2-weighted (T2W) planning images were also performed in the neck region of five normal human volunteers.

Ureteroenteric Strictures After Open Radical Cystectomy and Urinary Diversion: The University of Southern California Experience.

Objective: To evaluate the risk factors, management, and outcomes of benign ureteroenteric strictures (UES) in patients undergoing open radical cystectomy (RC) and urinary diversion for urothelial bladder carcinoma.

Materials And Methods: Using our institutional review board-approved institutional bladder cancer database, we identified 1964 patients who underwent RC for urothelial bladder carcinoma between 1971 and 2008. Patients underwent a uniform refluxing ureteroenteric anastomosis technique to ileum.

Development and Validation of a Novel Robotic Procedure Specific Simulation Platform: Partial Nephrectomy.

Purpose: We developed a novel procedure specific simulation platform for robotic partial nephrectomy. In this study we prospectively evaluate its face, content, construct and concurrent validity.

Materials And Methods: This hybrid platform features augmented reality and virtual reality.

A novel interface for the telementoring of robotic surgery.

Objective: To prospectively evaluate the feasibility and safety of a novel, second-generation telementoring interface (Connect(™) ; Intuitive Surgical Inc., Sunnyvale, CA, USA) for the da Vinci robot.

Materials And Methods: Robotic surgery trainees were mentored during portions of robot-assisted prostatectomy and renal surgery cases.
