A generalized health index: automated thoracic CT-derived biomarkers predict life expectancy.

Objective: To identify image biomarkers associated with overall life expectancy from low-dose computed tomography and integrate them as an index for assessing an individual's health.

Methods: Two categories of CT image features, body composition tissues and cardiopulmonary vasculature characteristics, were quantified from LDCT scans in the Pittsburgh Lung Screening Study cohort(n = 3,635). Cox proportional-hazards models identified significant image features which were integrated with subject demographics to predict the subject's overall hazard.

XRayWizard: Reconstructing 3-D lung surfaces from a single 2-D chest x-ray image via Vision Transformer.

Background: Chest x-ray is widely utilized for the evaluation of pulmonary conditions due to its technical simplicity, cost-effectiveness, and portability. However, as a two-dimensional (2-D) imaging modality, chest x-ray images depict limited anatomical details and are challenging to interpret.

Purpose: To validate the feasibility of reconstructing three-dimensional (3-D) lungs from a single 2-D chest x-ray image via Vision Transformer (ViT).

Interobserver and Intraobserver Reliability in Sonoelastographic Assessment of Thyroid Nodules.

Background: Thyroid ultrasonography is the first and perhaps most fundamental step for the radiological distinction of benign and malignant nodules. In this study, 2 radiologists reviewed the sonoelastographic and Doppler images of thyroid nodules and evaluated for the intraobserver and interobserver reliability.

Purpose: We aimed to determine confusing nodule identifiers and sonographic features differently defined by observers.

Osteochondral Lesions of the Talus May Cause the Vacuum Phenomenon in the Ankle Joint.

The few reports available on the vacuum phenomenon in the ankle joint refer to osteoarthritic and traumatic lesions. We present the first case concomitant with an osteochondral lesion of the talus. This case report presents computed tomographic images of the ankle.

The role of mean platelet volume in nonalcoholic fatty liver disease without cardiovascular comorbidities, obesity and diabetes mellitus.

Background: While the relation of mean platelet volume (MPV) with inflammatory diseases is obvious, its role in nonalcoholic fatty liver disease (NAFLD) without cardiovascular comorbidities, obesity and diabetes mellitus is not clear.

Methods: A total of 249 patients (nonobese, nondiabetic and not having cardiac diseases) who underwent an abdominal ultrasonography assessment were enrolled. They were divided according to the absence (group 1) or presence (group 2) of hepatic steatosis.

Sclerosing encapsulated peritonitis: typical imaging findings for easy diagnosis.

Unlabelled: Sclerosing encapsulated peritonitis (SEP) is a rare disease characterized by intestinal encasement within a fibrocollagenous membrane. Diagnosis of SEP may be challenging due to a lack of specific symptoms. Demonstration of clustered intestinal segments surrounded by a membranous sac by various imaging modalities is crucial to reveal the presence of SEP.
