연구실 소개
허진 교수의 연구실은 심장과 뇌혈관 질환의 정밀 진단을 목표로 하며, 특히 심장에서 기인하는 뇌졸중의 원인을 비침습적으로 정확하게 파악하는 데 중점을 두고 있습니다. 다단계 촬영 기반의 심장 CT 및 이중 에너지 CT를 활용한 심방세동부 혈전과 순환 정체를 구별하는 기술 개발이 핵심 연구 과제입니다. 또한, 폐의 미세 병변 진단을 위한 CT fluoroscopy 유도 생검 기법의 정확성 평가 등 영상의학의 정밀화와 임상 적용을 견인하고 있습니다.

15Two-phase 64-section cardiac CT angiography is a noninvasive sensitive modality for detecting LAA thrombi and differentiating thrombus from circulatory stasis in stroke patients.
Dual-energy cardiac CT is a highly sensitive modality for detecting LAA thrombus and for differentiating thrombus from SEC in patients with stroke.
BACKGROUND AND PURPOSE: A noninvasive method with high reliability and accuracy comparable to transesophageal echocardiography for identification of left atrial appendage thrombus would be of significant clinical value. The aim of this study was to assess the diagnostic performance of a dual-enhanced cardiac CT protocol for detection of left atrial appendage thrombi and for differentiation between thrombus and circulatory stasis in patients with stroke. METHODS: We studied 83 consecutive patient

OBJECTIVE: The purpose of this study was to evaluate the diagnostic performance of CT fluoroscopy-guided percutaneous needle aspiration biopsy of ground-glass opacity (GGO) pulmonary lesions. MATERIALS AND METHODS: Twenty-eight patients with GGO lesions who underwent CT fluoroscopy-guided needle aspiration biopsy were enrolled in this study. GGO lesions were divided into three groups according to their size: group 1, lesions < or = 10 mm (n = 10); group 2, lesions 11-20 mm (n = 10); and group 3,
BACKGROUND AND PURPOSE: We assessed the diagnostic performance of 2-phase 64-slice cardiac computed tomographic angiography (CCTA) for the detection of a cardiac source of embolism in stroke patients using transesophageal echocardiography (TEE) as the reference standard. METHODS: We selected 137 patients who had experienced a recent episode of stroke and had undergone both 2-phase 64-slice CCTA and TEE within a period of 5 days. A potential cardiac source of embolism detected at both CCTA and TE
The cytologic tumor marker c-CYFRA was positively associated with EGFR mutations in NSCLC. EGFR mutation-positive NSCLCs have relatively lower glycolysis compared with NSCLCs without EGFR mutation.
Sixty-four-section cardiac CT angiography is a noninvasive and sensitive modality for detecting thrombi in the LAA of stroke patients. Although TEE is currently considered the reference standard modality for detecting LAA thrombi, 64-section cardiac CT angiography has the potential to become a useful modality for detection of intracardiac thrombus.
Using MPR images enables more accurate preoperative T staging of gastric cancer, but not for N staging in either classification system.
The MDCT is very sensitive in detecting small osteolytic lesions in the spine, as compared with MRI and FDG-PET.
Sixty-four-slice CTCA is a noninvasive modality that allows quantification of coronary artery plaques. However, reliable classification of noncalcified plaques as vulnerable or stable plaques based on CT density measurements is currently limited.
