Prognostic value of CT-derived fractional flow reserve and fat attenuation index in patients with suspected coronary artery disease: a sex-disaggregated analyses.

Background: There are sex differences in many risk factors associated with coronary artery disease (CAD). CT-derived fractional flow reserve (CT-FFR) and fat attenuation index (FAI) have been shown to independently predict cardiovascular events. We aimed to examine the impact of sex on the prognostic value of CT-FFR and FAI in suspected CAD patients, and to examine the incremental prognostic value of FAI over CT-FFR in both sex.

CT imaging features regarding ground-glass nodules and solid lesions reflect prognostication of synchronous multiple lung adenocarcinoma.

The prognosis of synchronous multiple lung adenocarcinoma (SMLA) dramatically differs due to its nature of multiple primaries or intrapulmonary metastases. This study aimed to assess computed tomography (CT)-reflected SMLA features regarding ground-glass nodules (GGNs) and solid lesions and their correlation with prognostication. One seventy eight SMLA patients who underwent surgical resection were reviewed.

The Efficacy of Fosbretabulin Disodium Combined with Radiofrequency Ablation in Lung Cancer.

Radiofrequency ablation (RFA) is a technology that uses radiofrequency thermal effect to induce coagulation necrosis of tumor tissue under the guidance of imaging. However, distant metastasis of tumor cells caused by tumor angiogenesis can lead to incomplete tumor clearing. In this study, LLC1 cell line was used for the construction of subcutaneous xenografts.

Correlation Analysis of Computed Tomography Features and Pathological Types of Multifocal Ground-Glass Nodular Lung Adenocarcinoma.

To investigate the correlation between computed tomography (CT) image characteristics of multiple lung ground-glass nodules (GGNs) and pathological classification, the CT image data of multiple lung GGN patients confirmed by pathology ( = 132) in our hospital were collected. The imaging features of GGNs were analyzed by qualified physicians, including lesion size (diameter, volume, and mass), location, CT values (mean and relative CT values), lesion morphology (round and irregular), marginal structure (pagination and burr), internal structure (bronchial inflation sign), and adjacent structure (pleural depression). CT imaging analysis was performed for the subtype of infiltrating adenocarcinoma (IAC).

The risk factors for the failure of hook wire localization of ground glass nodules prior to thoracoscopic surgery.

Objectives: To retrospectively analyse the potential influencing factors of CT-guided hook wire localization failure prior to thoracoscopic resection surgery of ground glass nodules (GGNs), and determine the main risk elements for localization failure.

Methods: In all, 372 patients were included in this study, with 21 patients showing localization failure. The related parameters of patients, GGNs, and localization were analysed through univariate and multiple logistic regression analysis to determine the risk factors of localization failure.

Carotid web and ischemic stroke: a CT angiography study.

Objectives: We sought to explore the prevalence, demographics, clinical and imaging features of the Carotid web (CaW) on CT angiography (CTA) in patients with cryptogenic and non-cryptogenic stroke through a large-scale retrospective study.

Materials And Methods: A total of 1662 patients with ischemic stroke and had a neck CTA were retrospectively reviewed. An extensive clinical workup was performed to identify patients with cryptogenic stroke.
