Computed Tomography-based Lung Residual Volume and Mortality of Patients With Coronavirus Disease-19 (COVID-19).

Rationale And Objectives: To assess the effect of computed tomography (CT)-based residual lung volume (RLV) on mortality of patients with coronavirus disease 2019 (COVID-19).

Materials And Methods: A single-center, retrospective study of a prospectively maintained database was performed. In total, 138 patients with COVID-19 were enrolled.

Dual fluoroscopy with live-image digital zooming significantly reduces patient and operating staff radiation during fenestrated-branched endovascular aortic aneurysm repair.

Objective: Fenestrated-branched endovascular aneurysm repair (F/B-EVAR) is a complex procedure that generates high radiation doses. Magnification aids in vessel cannulation but increases radiation. The aim of the study was to compare radiation doses to patients and operating room staff from two fluoroscopy techniques, standard magnification vs dual fluoroscopy with live-image digital zooming during F/B-EVAR.

CT-Based Hepatic Residual Volume and Predictors of Outcomes of Patients with Hepatocellular Carcinoma Unsuitable for Surgical Therapy Undergoing Transarterial Chemoembolization.

Rationale And Objectives: To assess the association between baseline CT-based volumetric parameters and biochemical hepatic evaluations, such as, Child-Pugh, MELD score, and modified MELD-Na score, on the prediction of outcomes of patients with HCC undergoing transarterial chemoembolization (TACE).

Materials And Methods: A retrospective of a prospectively maintained database, single arm, and single center study was performed including 41 patients with diagnosis of hepatocellular carcinoma treated with TACE. Study endpoints included liver dysfunction (new events of ascites, encephalopathy, and/or death) and overall survival rate.
