Objectives: To compare the average number of culprit arteries per patient, clinical success rate, and hemoptysis-free survival rate between hemoptysis patients with multidetector computed tomography (MDCT) angiography prior to bronchial artery embolization (BAE) and those without preprocedural MDCT angiography METHODS: This retrospective study was approved by the institutional review board with waiver of patient informed consent. From September 2012 to March 2017, 157 consecutive hemoptysis patients had been undergoing BAE. Among them, 106 patients received preprocedural MDCT angiography (MDCT group), while 51 patients did not receive preprocedural MDCT angiography (control group). The average number of culprit arteries per patient, clinical success rate, and hemoptysis-free survival rate were compared between the two groups.
Results: The average number of culprit ectopic bronchial arteries and that of non-bronchial systemic arteries originating from the subclavian and internal mammary arteries per patient in the MDCT group were both significantly higher than those in the control group (0.15 ± 0.51 vs 0.04 ± 0.20, p = 0.022, and 0.17 ± 0.56 vs 0.08 ± 0.39, p = 0.040, respectively). The clinical success rate of BAE with preprocedural MDCT angiography tended to be higher than that without MDCT angiography (97.2 vs 88.2%, p = 0.057). Importantly, patients in the MDCT group had a significantly higher hemoptysis-free early survival rate compared to those in the control group (96.1 vs 86.7%, p = 0.031).
Conclusions: Preprocedural MDCT angiography helps detect culprit ectopic bronchial arteries and non-bronchial systemic arteries originating from subclavian and internal mammary arteries during BAE, and can improve the hemoptysis-free early survival rate, which could be recommended as a regular examination prior to BAE in patients with hemoptysis.
Key Points: • Preprocedural MDCT angiography helps detect culprit ectopic bronchial arteries and NBSAs originating from subclavian and internal mammary arteries during BAE. • Conducting MDCT angiography prior to BAE can improve hemoptysis-free early survival rate in hemoptysis patients.

Objectives: This study aimed to evaluate the feasibility and accuracy of non-electrocardiogram (ECG)-triggered chest low-dose computed tomography (LDCT) with a kV-independent reconstruction algorithm in assessing coronary artery calcification (CAC) degree and cardiovascular disease risk in patients receiving maintenance hemodialysis (MHD).
Methods: In total, 181 patients receiving MHD who needed chest CT and coronary artery calcium score (CACS) scannings sequentially underwent non-ECG-triggered, automated tube voltage selection, high-pitch chest LDCT with a kV-independent reconstruction algorithm and ECG-triggered standard CACS scannings. Then, the image quality, radiation doses, Agatston scores (ASs), and cardiac risk classifications of the two scans were compared.

Background: Hyperdense middle cerebral artery sign (HMCAS) on a non-enhanced multidetector computed tomography (MDCT) scan is considered an important radiological marker in detecting acute arterial thrombotic occlusion, and it is one of the earliest signs of ischemic cerebrovascular accident (CVA). This finding has been observed within 90 min of symptom onset. Modern approaches to patients with cerebral infarction emphasize early diagnosis and management.

Background: The purpose of our study was to investigate the association between non-alcoholic fatty liver disease (NAFLD) and abdominal aortic aneurysms (AAA) progression using non-enhanced computed tomography (CT) and CT angiography (CTA).
Methods: Patients with AAA and age- and sex-matched healthy subjects who underwent abdominal CTA and non-enhanced CT examination between January 2015 and January 2023 from four hospitals were retrospectively analyzed. Patients with AAA were divided into progression (growth rate > 10 mL/year) and non-progression groups, as well as those with NAFLD and without NAFLD, based on abdominal CT results.

Objectives: This study aimed to investigate the impact of changing inspiratory depth from end- to mid-inspiratory level on the iodine concentration of lung parenchyma and main pulmonary artery in dual-energy CT pulmonary angiography.
Methods: This retrospective study included patients who underwent dual-energy CT pulmonary angiography from July 2020 to June 2023. Patients were instructed to hold their breath at end- and mid-inspiratory levels before and after January 2022, respectively.

Background: The personalized, free-breathing, heart rate-dependent computed tomography angiography (CTA) protocol can significantly reduce the utilization of contrast medium (CM). This proves especially beneficial for patients with chronic obstructive pulmonary disease (COPD) undergoing coronary artery CTA examinations.
Objective: The aim of this study was to evaluate the feasibility of a personalized CT scanning protocol that was tailored to patients' heart rate and free-breathing for coronary CTA of patients with COPD.
