Radiology
January 2025
From the Department of Radiology and Research Institute of Radiology (Y.A., S.M.L., J.C., K.H.D., J.B.S.) and Department of Cardiothoracic Surgery (S.H.C.), University of Ulsan College of Medicine, Asan Medical Center, 88 Olympic-ro 43-gil, Songpa-gu, Seoul 05505, Republic of Korea.
Background The ninth edition of the TNM classification for lung cancer revised the N2 categorization, improving patient stratification, but prognostic heterogeneity remains for the N1 category. Purpose To define the optimal size cutoff for a bulky lymph node (LN) on CT scans and to evaluate the prognostic value of bulky LN in the clinical N staging of lung cancer. Materials and Methods This retrospective study analyzed patients who underwent lobectomy or pneumonectomy for lung cancer between January 2013 and December 2021, divided into development (2016-2021) and validation (2013-2015) cohorts.

Background Indeterminate focal liver observations in patients at risk for hepatocellular carcinoma (HCC) may require invasive biopsy or follow-up, which could lead to delays in definitive categorization and to postponement of treatment. Purpose To examine clinical effect of contrast-enhanced US (CEUS) in participants with high-risk indeterminate liver observations categorized as Liver Imaging Reporting and Data System (LI-RADS) category LR-4 (probably HCC) or LI-RADS category LR-M (probably or definitely malignant but not HCC specific) at CT or MRI. Materials and Methods This was a secondary analysis of a prospective international multicenter validation study for CEUS LI-RADS (January 2018 to August 2021).

The superior hypogastric plexus (SHP) contains afferent nociceptive fibers from the pelvic structures, thus the SHP block is employed in the chronic pelvic pain (CPP) treatment in patients who do not respond to conservative treatments. A 60-year-old female patient, who did not respond to conservative treatment, underwent SHP neurolytic block after a successful diagnostic block. An excessive oblique angle approach was applied due to physical restrictions, the needle passed through the intervertebral disc resulting in the contralateral side SHP block, and the procedure was also repeated to the other side SHP.

This study aimed to evaluate the visualization of right adrenal vein (RAV) in non-contrast-enhanced multi-detector computed tomography (MDCT) and its guiding role for right adrenal venous sampling (AVS) in patients with primary aldosteronism (PA). A total of 237 patients diagnosed with PA who underwent successful AVS procedures from January 2020 to March 2021 were retrospectively analyzed. The non-contrast-enhanced MDCT image features of RAV included the degree of visualization and the position of RAV orifice.

Introduction: Ankylosing spondylitis (AS), a chronic inflammatory spondyloarthropathy affecting the spine, progressively leads to increased spinal stiffness. This condition increases the risk of spine fractures in patients, even from trivial injuries. The process of slow bone formation within the ligaments of the spine and the fusion of the spinal diarthrosis contribute to the most prominent symptom of progressive stiffness of joints, predominantly affecting the spine and sacroiliac joints.
