Magnetic resonance imaging-assessed synovial and bone changes in hand and wrist joints of rheumatoid arthritis patients
Kyung-Ann Lee, Sang-Ho Min, Tae-Hyung Kim, Sang-Heon Lee, Hae-Rim Kim
Korean J Intern Med. 2019;34(3):651-659. Published online November 24, 2017
Background/Aims: Magnetic resonance imaging (MRI) is a sensitive and useful method for the detection of synovitis and joint destruction in rheumatoid arthritis (RA) patients. However, the patterns of MRI-detected bone erosion, bone marrow edema (BME), synovitis, and tenosynovitis have received insuf..

Experiences of magnetic resonance imaging scanning in patients with pacemakers or implantable cardioverter-defibrillators
Donghoon Han, Si-Hyuck Kang, Youngjin Cho, Il-Young Oh
Korean J Intern Med. 2019;34(1):99-107. Published online April 4, 2018
Background/Aims: Despite the U.S. Food and Drug Adminstration approving a magnetic resonance imaging (MRI)-conditional pacemaker system in 2011, many physicians remain reluctant to perform MRI scanning in patients with cardiac implantable electronic devices. Herein, we aimed to evaluate the real-wor..

Hypersensitivity myocarditis confirmed by cardiac magnetic resonance imaging and endomyocardial biopsy
Yumi Park, Sung Gyun Ahn, Anna Ko, Sang Ho Ra, Jaehwang Cha, Yong Gwan Jee, Ji Hyun Lee
Korean J Intern Med. 2014;29(2):236-240. Published online February 27, 2014
Myocarditis often occurs due to viral infections and postviral immune-mediated responses. Hypersensitivity myocarditis is a rare form of myocarditis. Numerous drugs can induce myocarditis, which is typically reversible after withdrawal of the causative agent. Here, we report a case of hypersensitivi..

Hannah Seok, Eun Young Lee, Eun Yeong Choe, Woo In Yang, Joo Young Kim, Dong Yeob Shin, Ho Jin Cho, Tae Sung Kim, Mi Jin Yun, Jong Doo Lee, Eun Jig Lee, Sung-Kil Lim, Yumie Rhee
Korean J Intern Med. 2013;28(1):81-88. Published online December 28, 2012
Background/AimsAlthough magnetic resonance imaging (MRI) is a good visual modality for the evaluation of pituitary lesions, it has limited value in the diagnosis of mixed nodules and some cystic lesions. We evaluated the usefulness of 18F-fluorodeoxyglucose positron..

A Case of Nonsecretory Multiple Myeloma with Atypical Imaging Features
Hwa Yeon Lee, Seung Min Yoo, In Sup Song, Hyeon Yu, Jong Beum Lee, Jong Wook Shin, In Won Park
Korean J Intern Med. 2006;21(3):202-205. Published online September 30, 2006
Multiple myeloma usually shows homogeneous enhancement on contrast-enhanced Magnetic Resonance imaging (MRI), and is accompanied by a monoclonal gammopathy in serum or urine. We report a case of nonsecretory myeloma, the diagnosis was difficult due to the absence of a monoclonal gammopathy and th..
