Lee J, Lee A, Park J, Moon J, Park J, Kim S, et al.
PLoS One . 2020 Apr; 15(4):e0231010. PMID: 32240236
Purpose: To evaluate the real-world diagnostic performance of high-resolution susceptibility-weighted imaging (HR-SWI) and investigate whether the reader's predictions can be used to find cases where HR-SWI finding and final clinical...

Khil E, Lee A, Chang K, Yun T, Hong H
Medicine (Baltimore) . 2015 Jul; 94(29):e1053. PMID: 26200611
Lung cancer is one of the most common neoplasms to appear leptomeningeal metastasis (LM). Contrast-enhanced magnetic resonance imaging (MRI) is better diagnostic choice for LM and usually shows focal nodular...

Runge V, Aoki S, Bradley Jr W, Chang K, Essig M, Ma L, et al.
Invest Radiol . 2015 Jun; 50(9):551-6. PMID: 26050021
This review focuses specifically on the developments in brain imaging, as opposed to the spine, and specifically conventional, clinical, cross-sectional imaging, looking primarily at advances in magnetic resonance imaging (MRI)...

Yoon J, Kim J, Kang W, Sohn C, Choi S, Yun T, et al.
Eur Radiol . 2013 Oct; 24(2):380-9. PMID: 24078054
Objectives: To retrospectively evaluate concordance rates and predictive values in concordant cases among multiparametric MR techniques and FDG-PET to grade cerebral gliomas. Methods: Multiparametric MR imaging and FDG-PET were performed...

Korean J Radiol . 2013 Aug; 14(4):662-72. PMID: 23901325
Objective: The purpose of this study was to differentiate true progression from pseudoprogression of glioblastomas treated with concurrent chemoradiotherapy (CCRT) with temozolomide (TMZ) by using histogram analysis of apparent diffusion...

Yun T, Sohn C, Han M, Kang H, Kim J, Yoon B, et al.
Invest Radiol . 2013 Jun; 48(11):795-802. PMID: 23764569
Objectives: Because arterial spin labeling (ASL) is completely noninvasive and provides absolute cerebral blood flow (CBF) information within a brief period, the technique has been increasingly used for patients with...
