Computer-aided diagnosis may improve the reader agreement on the positivity of screening results and follow-up recommendations in the assessment of low-dose screening CT.

BACKGROUND: Recently, a striking new clinical manifestation of Klebsiella pneumoniae (KP) infection referred to as invasive KP liver abscess syndrome (IKPLAS), defined by liver abscess with contemporaneous metastatic KP infections at other body sites has been documented. Until now, however, there have been relatively few reports regarding its radiologic features. PURPOSE: To describe the clinical and radiological features of IKPLAS patients, and to compare them with those with KP liver abscess w

EGFR-overexpression is associated with high SUV(max), large tumor diameter, and small GGO proportion. CT and FDG-PET findings, which are closely related to EGFR overexpression, can be valuable in the prediction of clinical outcome.

With the use of IR, low-dose computed tomography of the chest would achieve less image noise and better image quality compared to the FBP.

To evaluate the real-world treatment outcomes in patients with neovascular age-related macular degeneration (nAMD) in Korea, focusing on retinal fluid resolution. This multi-institutional retrospective chart review study, analyzed medical records of patients with nAMD (age ≥ 50 years) who received their first anti-vascular endothelial growth factor (VEGF) treatment in ophthalmology clinics across South Korea between January 2017 and March 2019. The primary endpoint was the proportion of patients

OBJECTIVE: The aim of the study was to evaluate the characteristics of coronary artery-to-pulmonary artery fistula (CPAF) found by coronary computed tomography (CT) angiography. METHODS: Among 10,121 cases of coronary CT angiography performed for 7 years, we found 32 cases of CPAF. We retrospectively evaluated the demographics, clinical symptoms, and anatomical characteristics such as the origin, number of origins, course, opening site of the fistula, and the presence of aneurysmal changes (defi

BACKGROUND: variant rs35705950 is the common and most significant risk variant for rheumatoid arthritis-interstitial lung disease (RA-ILD) in Western populations. However, little is known about its significant association with RA-ILD in Asian populations. We here investigate the association of rs35705950 with Korean patients with RA-ILD. METHODS: In this cross-sectional study, we genotyped rs35705950 in 2444 patients with RA. Among them, 683 patients with RA who have chest CT were divided into R

BACKGROUND: To introduce a prospective cohort for rheumatoid arthritis (RA) patients with interstitial lung disease (ILD) and to identify their clinical features in comparison with RA patients without ILD. METHODS: Using a multidisciplinary collaborative approach, a single-center cohort for RA patients with ILD (RA-ILD) was established in May 2017, and enrolment data from May 2017 to March 2021 were used to compare the clinical features of RA patients without ILD (RA-non ILD). Multivariable logi

ASC was more commonly peripheral than central, and showed internal low and heterogeneous attenuation and possessed lobulated, spiculated, or ill-defined margin on CT. Mean SUVmax of ASC was 8.3 ± 3.9. Central ASC was larger than peripheral ASC. Except for tumor size, central ASC and peripheral ASC showed no significant differences in pathology, FDG PET, and survival. Higher SUVmax was a poor prognostic factor.

본 논문에서는 지배주주 지분율과 은행차입금 비율 간에 어떠한 관계가 있는 지에 대하여 분석한다. 분석결과, 지배주주 지분율과 은행차입금 비중은 비선형관계가 있는 것으로 나타났다. 즉 일정 수준 미만의 지배주주 지분율이 있는 기업의 경우에는 은행차입금을 더 선호하는 반면, 일정 수준 이상으로 지배주주가 소유하고 있는 기업의 경우에는 은행차입금 비중이 유의적으로 감소하는 것으로 나타났다. 이는 지배주주 소유지분율이 낮은 기업에서는 비용 감소를 통한 기업가치 극대화를 위해 은행차입금을 선호하는 반면, 지배주주가 상당한 수준의 지분을 가지고 있는 경우 지배주주는 은행차입을 통하여 자금조달비용을 절감하는 것보다 은행차입으로부터 발생하는 모니터링을 회피하고자 하는 유인이 더욱 강한 것으로 해석된다. 한편 기업특성을 고려하여 지배주주 지분율과 부채종류의 선택간의 관계를 분석한 결과, 재무적 곤경이 상대적으로 높은 기업은 지배주주 지분율이 낮은 구간에서도 은행차입을 회피하는 결과를 보였다. 한편
