Purpose: This study examined longitudinal changes in interstitial lung abnormalities (ILAs) and predictors of clinically significant interstitial lung diseases (ILDs) in a screening population with ILAs.

Materials and methods: We retrieved 36891 low-dose chest CT records from screenings between January 2003 and May 2021. After identifying 101 patients with ILAs, the clinical findings, spirometry results, and initial and follow-up CT findings, including visual and artificial intelligence-based quantitative analyses, were compared between patients diagnosed with ILD (n = 23, 23%) and those who were not (n = 78, 77%). Logistic regression analysis was used to identify significant parameters for the clinical diagnosis of ILD.

Results: Twenty-three patients (n = 23, 23%) were subsequently diagnosed with clinically significant ILDs at follow-up (mean, 8.7 years). Subpleural fibrotic ILAs on initial CT and signs of progression on follow-up CT were common in the ILD group (both p < 0.05). Logistic regression analysis revealed that emerging respiratory symptoms (odds ratio [OR], 5.56; 95% confidence interval [CI], 1.28-24.21; p = 0.022) and progression of ILAs at follow-up chest CT (OR, 4.07; 95% CI, 1.00-16.54; p = 0.050) were significant parameters for clinical diagnosis of ILD.

Conclusion: Clinically significant ILD was subsequently diagnosed in approximately one-quarter of the screened population with ILAs. Emerging respiratory symptoms and progression of ILAs at follow-up chest CT can be predictors of clinically significant ILDs.

Total gastrectomy with Roux-en-Y esophagojejunostomy is a common surgical treatment for early gastric cancer; however, postoperative complications such as anastomotic leaks remain a serious risk. This report details a 59-year-old female who underwent total gastrectomy with Roux-en-Y esophagojejunostomy for early gastric cancer, followed by percutaneous embolization for esophagojejunal (EJ) anastomotic leakage. Despite initial percutaneous drainage for fluid accumulation at the EJ site, subsequent CT revealed significant anastomotic dehiscence. Endoscopic treatment was ineffective and surgical intervention posed a high risk of mortality; therefore, percutaneous embolization was requested. This involved four sessions using cut gel foam, N-butyl-2-cyanoacrylate, and lipiodol. The procedure was successful without complications and led to complete resolution of the leakage and dehiscence. Follow-up CT scans at 6- and 32-months post-procedure confirmed the absence of recurrence. This case highlights the potential of percutaneous embolization as a treatment option for anastomotic leakage after Roux-en-Y esophagojejunostomy.

Pulmonary artery pseudoaneurysms (PAPs) are rare and can occasionally be overlooked as a cause of hemoptysis. The rupture of PAPs may lead to severe and massive hemoptysis and asphyxiation, necessitating prompt and accurate diagnostic measures, including CT angiography, in conjunction with clinical awareness for adequate management. The aim of this pictorial essay is to establish a strategy for endovascular intervention based on a comprehensive understanding of the etiology and hemodynamics of bronchopulmonary circulation for effective and rapid PAP treatment.

The value-based payment (VBP) system aims to improve the quality of healthcare while enhancing cost-efficiency, delivering better patient outcomes without increasing overall healthcare costs. It has been proposed as an alternative payment system to help sustain national insurance systems in response to the social and economic challenges posed by rising healthcare expenditures. Radiology plays a crucial role in disease prevention, diagnosis, and treatment; however, it is often undervalued. This review explores how radiology can be fully recognized for its inherent value in the VBP system and continue to enhance patient outcomes and societal value.

Dermoid cysts originate from embryonic tissues trapped in the cranial fusion lines and typically manifest extra-axially. However, intradiploic dermoid cysts are rare among cranial tumors, and their rupture has been sparsely documented. We present a case showcasing a remarkable phenomenon-the spontaneous rupture of an intradiploic dermoid cyst into the subarachnoid space, displaying a distinct "volcano-like" appearance on CT and MRI scans. This case represents the first documented instance of spontaneous intracranial rupture of an intradiploic dermoid cyst into the subarachnoid space. Although uncommon, this rupture poses a risk of severe complications, such as chemical meningitis and vasospasm. This extraordinary presentation of an uncommon lesion at an atypical location may contribute to a better understanding of the potential mechanisms of rupture, thereby emphasizing the importance of recognition and exploration.

In 2023, Korea had 104953 diagnostic radiological devices installed across 43529 medical institutions, with 398947394 examinations performed. The number of devices and examinations rank among the highest by OECD standards. The average medical radiation dose per individual was 3.13 mSv, representing an increase of approximately 27.2% compared to 2020, contrary to the global trend of decreasing radiation exposure. This study aimed to review various research activities by the Korean Society of Radiology, its members, and other researchers to reduce radiation exposure and explore additional strategies to further mitigate this issue.

In the rapidly evolving healthcare environment, radiologists strive to establish their rightful place. Thus, there is a need for enhanced outpatient and clinical education within the Department of Radiology and exploration of its methodologies. Accordingly, the Korean Society of Radiology established a task force to investigate the clinical and outpatient practice status of radiologists overseas, current state of related education, involvement of other specialties in radiologic practices and education in Korea, and clinical and outpatient practice status among Korean radiologists. Furthermore, a survey on clinical competency enhancement was conducted among the members of the Korean Society of Radiology. These findings suggest the need for visibility and clinical competency enhancement in radiologists and methodologies for strengthening clinical competencies.
