In adnexal torsion, the ovary, ipsilateral fallopian tube, or both twist with vascular pedicle, resulting in compromise. Unrelieved torsion is likely to cause hemorrhagic infarction as degree of arterial occlusion increases. Therefore, early diagnosis important preserve affected ovary. Adnexal commonly accompanies an ovarian neoplasm cyst but can also occur normal ovaries, usually children. Although ultrasonography typically initial emergent examination, computed tomography (CT) and magnetic...
The purpose of this study was to determine the potential CT for distinguishing tuberculous peritonitis from peritoneal carcinomatosis in 135 clinically or pathologically proven cases.Abdominal scans patients (n = 42) and 93) with documented omental, mesenteric, pathology were retrospectively reviewed. findings evaluated each group morphologic appearance mesenteric omental abnormalities as well visualization spleen liver, lymph nodes, ascites. Statistical comparisons using multivariate...
The prevalence of coronary artery fistula (CAF) based on angiographic findings has been reported. However, the number incidentally found CAFs is increasing as CT angiography (CTA) become popular. purpose this study was to determine and types detected with CTA.Between March 2009 November 2011, 6341 patients underwent CTA at one institution. CAF retrospectively evaluated, morphologic features were analyzed, including vessel origin, drainage site, size, presence an aneurysmal sac. We also...
Purpose: This study investigates the impact of deep learning-based contrast boosting (DL-CB) on image quality and measurement reliability in low-contrast media (low-CM) CT for pre-transcatheter aortic valve replacement (TAVR) assessment. Methods: retrospective included TAVR candidates with renal dysfunction who underwent low-CM (30-mL: 15-mL bolus followed by 50-mL 30% iomeprol solution) pre-TAVR between April December 2023, along matched standard-CM controls (n = 68). Low-CM images were...
Purpose The purpose of this work was to describe the radiologic and clinical manifestations n-butyl-2-cyanoacrylate pulmonary embolism (PE) after endoscopic injection sclerotherapy (EIS) for gastric variceal bleeding. Method From 1992 1999, medical records 140 patients who had undergone EIS using were reviewed identification respiratory symptoms amount injection, their pre-and postprocedure chest radiographs identify PE. In with PE, (6/6), CT scans (3/6), lung perfusion follow-up (6/6)...
We investigated the association between diabetes duration and extent severity of coronary artery disease (CAD) as well long-term clinical outcomes using computed tomography angiography (CCTA) in asymptomatic type 2 diabetic patients.We analysed 933 patients without known CAD who underwent CCTA. Patients were divided into three groups according to diabetes: <5 years, 5-10 ≥10 years. Stenosis by CCTA was scored none (0%), non-obstructive (1-49%), or obstructive (≥50%) for each segment. For...

To evaluate the feasibility and utility of deep learning-based computer-aided diagnosis (DL-CAD) for detection pulmonary nodules on coronary artery calcium (CAC)-scoring computed tomography (CT). This retrospective study included 273 patients (aged 63.9±13.2 years; 129 men) who underwent CAC-scoring CT. A DL-CAD system based thin-section images was used nodule detection, two independent junior readers reviewed standard CT scans with without referencing results. reference established through...
The objective was to analyse the potential of CT distinguish pneumonic-type bronchioloalveolar cell carcinoma (BAC) from infectious pneumonia. study consisted 21 patients with pathologically proven BAC and 30 Both groups had patchy or diffuse consolidation more than half area a lobe lobes on CT. findings in these two were compared regard morphological appearance, including angiogram, air bronchogram, mucous contrast enhancement pattern, pseudocavitation, cavity air–fluid level, location,...
The purpose of this essay is to illustrate the CT findings variable benign tumors tracheobronchial tree and correlate pathologic in 17 patients.The tracheal were eccentric, well-defined, polypoid masses all cases. endobronchial confined within bronchus cases, atelectasis or pneumonia distal parenchyma was frequently associated. Of six hamartomas, one a fatty mass, two nodules with calcification. others soft-tissue-density nodules. lipomas manifested as fat density on scans both other...
With the increasing use of multidetector computed tomography (MDCT), number incidentally detected ventricular septal aneurysms (VSAs) in adults has increased. However, to date, there are not sufficient well-organized data regarding VSAs on MDCT.To evaluate CT findings and correlate with clinical features.We performed a retrospective review cardiac reports our electronic database 3402 patients who underwent ECG-gated scans using 64-slice or dual-source from October 2006 December 2009 at...
OBJECTIVE We investigated the efficacy of coronary computed tomography angiography (CCTA) in predicting long-term risks asymptomatic patients with type 2 diabetes and compared it traditional risk factors. RESEARCH DESIGN AND METHODS analyzed 933 who underwent CCTA. Stenosis was considered obstructive (≥50%) each artery segment using The extent severity scores for disease (CAD) were evaluated. primary end point major adverse cardiovascular events (MACE), including all-cause mortality,...
Background The risk of developing tuberculosis (TB) in allogeneic hematopoietic stem cell transplantation (HSCT) recipients is expected to be relatively high an intermediate TB burden country. This single-center retrospective study was conducted investigate factors and the incidence after HSCT. Methods From January 2004 March 2011, 845 adult patients were enrolled. Starting April 2009, given isoniazid (INH) prophylaxis based on interferon-γ release assay results. analyzed before compared it...
An artificial intelligence (AI) model using chest radiography (CXR) may provide good performance in making prognoses for COVID-19.We aimed to develop and validate a prediction CXR based on an AI clinical variables predict outcomes patients with COVID-19.This retrospective longitudinal study included hospitalized COVID-19 at multiple medical centers between February 2020 October 2020. Patients Boramae Medical Center were randomly classified into training, validation, internal testing sets (at...
The treatment of acute promyelocytic leukemia with all-trans-retinoic acid (ATRA) sometimes results in a syndrome characterized by fever, respiratory distress, weight gain, pleural and pericardial effusion, pulmonary infiltrates. We report the radiologic features ATRA syndrome.During past 5 years, 69 patients were treated ATRA. Of this group, 15 developed syndrome. Serial chest radiographs evaluated retrospectively for presence nodules, consolidation, ground-glass opacity, septal lines,...
Korea is one of the highest indium-consuming countries worldwide. The present study aims to determine relationship between interstitial lung disorders and indium exposure in Korea.In 50 workers from seven plants, effect serum on lungs was determined using laboratory tests, spirometry, high-resolution computed tomography (HRCT).Higher Krebs von den Lungen-6 (KL-6) levels were associated with HRCT-detected changes. Workers high (≥3 µg/L) had longer durations a higher prevalence KL-6 surfactant...
To evaluate the natural course of coronary-to-pulmonary artery fistula (CPAF) detected on coronary computed tomography angiography (CCTA) and to propose potential treatment strategies.In this retrospective multicenter study, we assessed CCTA reports 188 CPAF patients evaluated between March 2009 June 2016. Fifty-seven were excluded because their follow-up (FU) periods less than 2 years. Information regarding demographic characteristics, past history, method, occurrence major adverse cardiac...
