研究室紹介
Professor Narae Eun's research lab specializes in diagnostic and interventional radiology, with a focus on improving the accuracy and reproducibility of medical imaging techniques for spinal and abdominal pathologies. The lab investigates advanced MRI sequences such as T1ρ and T2 mapping for early detection of intervertebral disc degeneration, and explores the role of imaging biomarkers like PD-L1 expression and tumor-infiltrating lymphocytes in guiding immunotherapy for breast cancer. Additionally, the lab contributes to interventional radiology innovations, including endovascular techniques for complex aortic aneurysms and automated software for tumor-feeding artery detection in hepatocellular carcinoma. The overarching research direction emphasizes precision diagnosis through multimodal imaging and image-guided interventions.

6Objective: To investigate the interobserver and test-retest reproducibility of T1ρ and T2 measurements of lumbar intervertebral discs using 3T magnetic resonance imaging (MRI). Materials and Methods: This study included a total of 51 volunteers (female, 26; male, 25; mean age, 54 ± 16.3 years) who underwent lumbar spine MRI with a 3.0 T scanner. Amongst these subjects, 40 underwent repeat T1ρ and T2 measurement acquisitions with identical image protocol. Two observers independently performed the
Purpose: Pembrolizumab is currently used to treat advanced triple-negative breast cancer (TNBC) and high-risk early TNBC with neoadjuvant chemotherapy (NAC). The tumor-infiltrating lymphocyte (TIL) level and programmed cell death ligand 1 (PD L1) status are predictors of response to NAC and immune checkpoint inhibitor treatment. We aimed to investigate whether the PD-L1 status in core needle biopsies (CNBs) could represent the whole tumor in TNBC. Materials and Methods: A total of 49 patients di
A 62-year-old man was admitted, and thoracic endovascular aortic repair (TEVAR) procedure was performed to treat an accidentally detected aortic aneurysm, which was 63 mm in diameter. While performing TEVAR, the passage of the stentgraft introducer system was impossible due to the prolapse of the introducer system into a wide-necked aneurysm; this aneurysm was located at the greater curvature of the proximal descending thoracic aorta. In order to advance the introducer system, a compliant balloo
Objective: To evaluate retrospectively the clinical effectiveness of FlightPlan for Liver (FPFL), an automated tumor-feeding artery detection software in cone-beam CT angiography (CBCTA), in identifying tumor-feeding arteries for the treatment of hepatocellular carcinoma (HCC) using three different segmentation sensitivities. Materials and Methods: The study included 50 patients with 80 HCC nodules who received transarterial chemoembolization. Standard digital subtracted angiography (DSA) and CB
Purpose : Intramedullary spinal lesions in the conus medullaris (CM), including tumors and vascular lesion, are rarelyreported. We reported various MR features of intramedullary spinal cord lesions involving the CM including ependymoma,hemangioblastomas, dermoid cyst, ventriculus terminalis and spinal AVF and tried to discuss them for differentialdiagnosis. Materials and Methods: Six patients (male: female = 4:2, mean age = 44.3 year old) were enrolled from the clinical databaseof our institute
내원 3개월 전 척추 수술을 시행 받았던 66세 여자 환자가요통 및 하지 동통으로 내원하였다. Magnetic resonance image상 척추체-추간판염 소견이 보였으며 조직 검사를 통한 세균 배양 검사에서 Enterococcus faecium과 Candida parapsilosis가동정되어 진균과 세균의 복합 감염으로 확인되었다. 저자는 적극적인 조직 배양 검사를 통해 진균과 세균의 복합 감염을 정확히 진단함으로써 이에 따른 적절한 치료를 시행하여 문헌고찰과 함께 보고하는 바이다. 또한 본 사례를 통해 진단율을 높이는 적극적인 조직 검사를 독려하고자 한다.
