Occhipinti M, Paoletti M, Bartholmai B, Rajagopalan S, Karwoski R, Nardi C, et al.
Respir Res . 2019 May; 20(1):101. PMID: 31122243
Background: The mechanisms underlying airflow obstruction in COPD cannot be distinguished by standard spirometry. We ascertain whether mathematical modeling of airway biomechanical properties, as assessed from spirometry, could provide estimates...

Varghese C, Rajagopalan S, Karwoski R, Bartholmai B, Maldonado F, Boland J, et al.
J Thorac Oncol . 2019 May; 14(8):1419-1429. PMID: 31063863
Objective: Most computed tomography (CT)-detected lung cancers are adenocarcinomas (ACs), representing lesions with variable tissue invasion, aggressiveness, and clinical outcome. Visual radiologic characterization of AC pulmonary nodules is both inconsistent...

Neurogastroenterol Motil . 2019 Apr; 31(7):e13608. PMID: 31025437
Background: During proctography, rectal emptying is visually estimated by the reduction in rectal area. The correlation between changes in rectal area, which is a surrogate measure of volume, is unclear....

Nakajima E, Frankland M, Johnson T, Antic S, Chen H, Chen S, et al.
PLoS One . 2018 Jun; 13(6):e0198118. PMID: 29856852
Lung adenocarcinoma (ADC), the most common lung cancer type, is recognized increasingly as a disease spectrum. To guide individualized patient care, a non-invasive means of distinguishing indolent from aggressive ADC...

Peikert T, Duan F, Rajagopalan S, Karwoski R, Clay R, Robb R, et al.
PLoS One . 2018 May; 13(5):e0196910. PMID: 29758038
Purpose: Optimization of the clinical management of screen-detected lung nodules is needed to avoid unnecessary diagnostic interventions. Herein we demonstrate the potential value of a novel radiomics-based approach for the...

Foley F, Rajagopalan S, Raghunath S, Boland J, Karwoski R, Maldonado F, et al.
Semin Thorac Cardiovasc Surg . 2016 Aug; 28(1):120-6. PMID: 27568149
Increased clinical use of chest high-resolution computed tomography results in increased identification of lung adenocarcinomas and persistent subsolid opacities. However, these lesions range from very indolent to extremely aggressive tumors....

Maldonado F, Duan F, Raghunath S, Rajagopalan S, Karwoski R, Garg K, et al.
Am J Respir Crit Care Med . 2015 Jun; 192(6):737-44. PMID: 26052977
Rationale: Screening for lung cancer using low-dose computed tomography (CT) reduces lung cancer mortality. However, in addition to a high rate of benign nodules, lung cancer screening detects a large...

Rettmann M, Holmes 3rd D, Breen J, Ge X, Karwoski R, Monahan K, et al.
Comput Methods Programs Biomed . 2014 Dec; 118(2):198-206. PMID: 25476706
Rationale And Objectives: Geometric analysis of the left atrium and pulmonary veins is important for assessing reverse structural remodeling following cardiac ablation therapy. Most volumetric analysis techniques, however, require laborious...
