Summary: This study aimed to validate the advantages of using orthogonal methods to measure left atrium volume and compare them with the simple maximal axial area. The results showed that the orthogonal methods, especially 3 diameters LAV and 3 areas LAV, had better correlation with the reference standard and higher reproducibility.

Summary: This study evaluated the association between left atrial epicardial fat and left atrial volume in patients with different types of atrial fibrillation (AF). The results showed that left atrial epicardial fat was larger in patients with paroxysmal AF, while larger left atrial volumes were associated with persistent/permanent AF.

Summary: The study aimed to differentiate left atrial appendage thrombus from circulatory stasis in patients with valvular heart disease using quantitative radiomic features from cardiac CT. The radiomic features extracted from early-phase CT showed potential diagnostic value in distinguishing thrombus from stasis, outperforming CT attenuation ratios.

Summary: This study found a significant correlation between the degree of pancreatic fibrosis and the extracellular volume fraction (ECV). The ECV was identified as a potential biomarker for pancreatic cancer with good diagnostic accuracy. It was suggested that the ECV reflects the progression of pancreatic fibrosis and may help predict the development of pancreatic cancer.

Summary: By analyzing preoperative contrast-enhanced CT images of 113 patients with ICC or HCC, it was found that tumor extracellular volume fraction (fECV) plays an important role in differentiating between these two tumors. The fECV value of ICC patients was significantly higher than that of HCC patients, and it can be used as an independent factor for differentiation.

Summary: In this feasibility study, optimized virtual contrast enhancement through generative adversarial networks (GAN) was successfully used to reduce the dose of iodine-based contrast medium (CM) during abdominal computed tomography (CT) in a large animal model. The results showed that the amount of CM for abdominal CT can be reduced by approximately 70% by GAN-based contrast enhancement with satisfactory image quality.

Summary: There is a significant correlation between the left atrial AP diameter measured on echocardiography and the volume measured on CT, suggesting that the AP diameter may be sufficient in predicting cardiovascular outcomes associated with increased atrial volume.

Summary: The efficacy of quantitative parameters derived from dual-energy computed tomography (DECT) for the preoperative prediction of early recurrence (ER) in patients with esophageal squamous cell carcinoma (ESCC) was assessed in this study. The results showed that arterial phase normalized iodine concentration (A-NIC) and pathological grade (PG) were identified as significant risk predictors of ER. A-NIC can be used to noninvasively predict preoperative ER in patients with ESCC, with an efficacy comparable to that of pathological grade.

Summary: The study aimed to determine a personalized and optimized contrast injection protocol for liver parenchymal enhancement. Results showed that the protocol based on 600 mgI/kg FFM achieved diagnostically optimized liver enhancement, improved patient-to-patient enhancement uniformity, and significantly reduced iodine load.

Summary: The study indicates that VRS can differentiate patients with UIP histological features from non-IPF diagnosis in CT images, showing predictive value. The sensitivity and specificity of VRS in predicting pathological UIP are comparable to standard qualitative CT assessment.

Summary: This study aimed to quantify lung parenchyma and airway wall enhancement using a single contrast-enhanced spectral detector CT. The results showed that lung density was higher at 40 keV compared to 100 keV, and wall thickness and enhancement were higher at 40 keV for arterial phases. Spectral CT can quantify lung parenchyma and airway wall enhancement, and further studies are needed to analyze inflammatory airway diseases.

Summary: This study evaluated the accuracy of an artificial neural network for automated detection of iodinated contrast agent in MDCT scans and the effect of contrast correction for osteoporosis screening. The results showed that the 2D DenseNet model with anatomy-guided slice selection outperformed others and successfully reduced the bias in bone mineral density measurements after contrast application.

Summary: This study found that left atrial (LA) size only affects 1-year recurrence rate after catheter ablation in the highest tertile group, while pulmonary vein (PV) to LA volume ratio (PV/LA%vol) can predict 1-year recurrence rate in all LA size groups. Patients with lower PV/LA%vol have a higher AF recurrence rate, and in patients with smaller LA size, PV/LA%vol is more accurate in predicting AF recurrence rate compared to LA dimension (LAD). Additionally, PV/LA%vol is associated with the PITX2 gene.
