이 교수의 연구실은 심혈관 영상의학과 진단 영상 기반의 질병 탐지 및 평가에 중점을 두고 있습니다. 특히 코로나19 환자에서의 혈전색전증 및 심장 마비 위험 요인, 비침습적 영상 검사(심장 MRI, CT, 초음파 등)를 통한 심장 기능 이상의 조기 진단에 대한 연구를 진행하고 있습니다. 또한 유방조영검사 및 간세포암 등 종양성 병변의 영상학적 특징 분석을 통해 정확한 진단을 위한 기반을 마련하고자 합니다.

Background The association of pulmonary embolism (PE) with deep vein thrombosis (DVT) in patients with coronavirus disease 2019 (COVID-19) remains unclear, and the diagnostic accuracy of D-dimer tests for PE is unknown. Purpose To conduct meta-analysis of the study-level incidence of PE and DVT and to evaluate the diagnostic accuracy of D-dimer tests for PE from multicenter individual patient data. Materials and Methods A systematic literature search identified studies evaluating the incidence o
On gadoxetic acid-enhanced MR images, hyperintense nodules can be differentiated with several imaging characteristics, especially a focal defect in contrast uptake and a hypointense rim, that indicate the diagnosis of hyperintense HCC.
The varying pooled incidences of overall and severe AARs to specific types of nonionic ICM do not remain as significant after adjusting confounders. Our results may support nonrestriction of certain types of nonionic ICM in the context of AAR avoidance.
The underestimation rate of invasive carcinoma in cases with DCIS at ultrasound-guided core biopsies was significantly higher for ACNB than for VAB. Furthermore, this difference does not change according to the lesion type on ultrasound. Therefore, ultrasound-guided VAB can be a useful method for the diagnosis of DCIS lesions presented as either mass or microcalcification.
Nearly half of recovered COVID-19 patients exhibited one or more abnormal CMR findings. Athletes and patients with normal cardiac enzyme levels showed a lower prevalence of abnormal CMR findings than non-athletes and patients with undetermined cardiac enzyme levels. Trial registration The study protocol was registered in the PROSPERO database (registration number: CRD42020225234).
Cardiac CT may have better diagnostic accuracy compared with TTE for the detection of mitral PVL and may be comparable to TEE for the detection and localization of PVL.
The combination of SAFIRE and APSCM at coronary CT angiography significantly improves objective image quality while maintaining diagnostic accuracy and reduced radiation dose. Online supplemental material is available for this article.
Measurement of Tg levels in the FNA of SOLs in the thyroid bed can be helpful in diagnosing tumor recurrence, because an FNA-Tg level lower than the threshold value has the added value of suggesting a benign lesion rather than tumor recurrence.
<b>OBJECTIVE.</b> The objective of our study was to investigate the utility of FDG PET/CT for the preoperative staging of subsolid non-small cell lung cancers (NSCLCs) with a solid portion size of 3 cm or smaller. <b>MATERIALS AND METHODS.</b> We retrospectively enrolled 855 patients with pathologically proven NSCLCs manifesting as subsolid nodules with a solid portion of 3 cm or smaller on CT. We then compared the diagnostic performances of FDG PET/CT and chest CT for detecting lymph node (LN),
