研究室紹介
Professor Eun-Ah Park's research lab specializes in diagnostic radiology and medical imaging, with a focus on optimizing computed tomography (CT) techniques for improved disease detection and characterization. The lab investigates advanced CT protocols—such as low-kilovoltage imaging, xenon ventilation CT, and 3D vascular anatomy analysis—to enhance image quality, reduce radiation dose, and improve diagnostic accuracy in pulmonary and cardiovascular diseases. Key research directions include quantitative and qualitative assessment of chronic obstructive pulmonary disease (COPD), coronary CT angiography, and venous thromboembolism. The lab also explores the integration of computer-aided detection (CAD) and multiplanar reconstruction techniques to support clinical decision-making in oncology and vascular imaging.

15PURPOSE: To evaluate the potential of xenon ventilation computed tomography (CT) in the quantitative and visual analysis of chronic obstructive pulmonary disease (COPD). MATERIALS AND METHODS: This study was approved by the institutional review board. After informed consent was obtained, 32 patients with COPD underwent CT performed before the administration of xenon, two-phase xenon ventilation CT with wash-in (WI) and wash-out (WO) periods, and pulmonary function testing (PFT). For quantitative
OBJECTIVE: This study was conducted to assess the feasibility of performing 100-kVp electrocardiogram (ECG)-gated coronary CT angiography, as compared to 120-kVp ECG-gated coronary CT angiography. MATERIALS AND METHODS: We retrospectively evaluated one hundred eighty five gender- and body mass index-matched 16-slice coronary CT sets of data, which were obtained using either 100 kVp and 620 effective mAs or 120 kVp and 500 effective mAs. The density measurements (image noise, vessel density, sign
In candidates for metastatectomy, reading with the aid of either CAD or MIP significantly improved the detection of malignant nodules compared with using thin-section CT alone.
OBJECTIVE: We wanted to describe the three-dimensional (3D) anatomic variations of the femoral vein (FV) and popliteal vein (PV) in relation to the accompanying artery using CT venography. MATERIALS AND METHODS: We performed a retrospective review of 445 bilateral (890 limbs) lower limb CT venograms. After the 3D relationship between the FV and PV and accompanying artery was analyzed, the presence or absence of variation was determined and the observed variations were classified. In each patient

Materials and Methods: We retrospectively evaluated one hundred eighty five gender- and body mass index-matched 16-slice coronary CT sets of data, which were obtained using either 100 kVp and 620 effective mAs or 120 kVp and 500 effective mAs.

The optimal enhancement of the pulmonary arteries and Fontan tract can be achieved by a 3-minute-delay scan irrespective of the intravenous route location.
Luminal obliteration, decreased caliber, fibrotic bands, ipsilateral muscle enlargement, and superficial collateral vein development are common CT findings in chronic DVT of the lower extremity.
OBJECTIVE: To evaluate the influence of papillary muscles and trabeculae on left ventricular (LV) cardiovascular magnetic resonance (CMR) analysis using three methods of cavity delineation (classic or modified inclusion methods, and the exclusion method) in patients with hypertrophic cardiomyopathy (HCM). MATERIALS AND METHODS: This retrospective study included 20 consecutive HCM patients who underwent 1.5-T CMR imaging with short-axis cine stacks of the entire LV. LV measurements were performed
