Summary: Features including age <= 5 years, elevated serum AFP, larger size, ill-defined border, calcification, absence of haemorrhage, intratumoural vessel, peripancreatic vessel invasion, distant metastasis, and lower ADC value can help differentiate PB from SPN in children. SPNs have higher ADC values compared to PB. There were no significant differences in terms of tumour capsule, pancreatic duct dilatation, or cystic degeneration area over 50% of the tumour volume between the two groups.

Summary: This study provides a quantitative meta-analysis of pancreatic CT perfusion studies, investigating the choice of study parameters, the ability to differentiate pancreatic diseases quantitatively, and the influence of acquisition and reconstruction parameters on reported results. The results showed significant differences in perfusion measurements between different pathologies despite the heterogeneity of study parameters. Statistical analysis identified the most influential parameters for future optimization and standardization of acquisition protocols.

Summary: A precision tissue sampling technique using radiomic habitats for ultrasound-guided targeted biopsies was successfully developed for patients with HGSOC. The CT/US fusion accuracy was high for larger pelvic tumours, but lower for smaller omental metastases. This technique can be seamlessly integrated into the clinical routine for HGSOC patients.

Summary: Recent epidemiological studies have reported increased risks of central nervous system (CNS) tumors and leukemia associated with computed tomography (CT) exposure during childhood. However, a previous analysis of the French CT cohort did not provide evidence of increased risks. This study, with an updated cohort and a longer follow-up, confirms the increased risks.

Summary: This study aimed to examine how often radiologists miss or detect incidental breast cancers on chest CT and compare the CT features between the two groups. By evaluating chest CT scans and medical records of breast cancer patients, it was found that 64.3% of incidental breast cancer lesions were missed by radiologists. Smaller lesions and those with lower enhancement ratios were more likely to be missed. However, when radiologists re-read the CTs with a focus on the breast area, they had higher accuracy in detecting breast cancers (90.1%, 87.9%, and 81.3%).

Summary: This study aimed to identify quantitative CT features for distinguishing well-differentiated pancreatic neuroendocrine tumors (PNETs) from poorly differentiated pancreatic neuroendocrine carcinomas (PNECs). The results showed that arterial/portal absolute enhancements were independent predictors with good diagnostic accuracy for differentiating between PNETs and PNECs. Arterial lesion enhancement had the highest diagnostic performance.

Summary: This study compared the differences between conventional CT images and virtual monoenergetic images (VMI) at dual-layer dual-energy CT (dlDECT) in CRC patients. The results showed that VMI40 had the highest quantitative image parameters, and adding VMI40 to conventional CT images improved the diagnostic performance for detecting CRC.

Summary: DECT parameters play an important role in distinguishing between metastatic and benign lung nodules in thyroid cancer. The study found that specific cutoff values for IC, NIC, lambda HU, NICPA, and Z(eff) can aid in diagnosing metastases.

Summary: The study found that low-dose neck CT scans from [F-18]-FDG PET-CT can provide comparable results to diagnostic neck CT scans in head and neck cancer patients. This enables SMI analysis in patients without a diagnostic neck CT but with a [F-18]-FDG PET-CT scan.

Summary: This study developed a CT-based method to quantify tracheal shape and evaluate its ability to distinguish between cases with or without tracheal invasion in patients with thyroid carcinoma. By selecting appropriate slices and features, this method can reliably identify tracheal invasion in DTC patients.

Summary: This study compared the accuracy of PET/CT parameters with CT parameters for directing bone biopsies. It found that metabolic 2-[F-18]FDG PET/CT parameters have more clinical impact for planning bone biopsies than CT parameters, with SUVmax and lesion size being important factors in detecting malignancy.

Summary: This study aimed to characterize thyroid nodules seen on Spectral Detector computed tomography (SDCT) and compare them with their Thyroid Imaging Reporting and Data System (TI-RADS) category on Ultrasound (US). The results showed that the spectral results of SDCT can assist in differentiating thyroid nodules of different risk levels.

Summary: The purpose of this study was to investigate the associations between cardiac magnetic resonance feature-tracking-derived myocardial strain parameters and volumetric function and hemodynamic parameters in patients with pulmonary hypertension. The results showed that impairment of myocardial strains was more strongly associated with alterations in ventricular function parameters than elevated pulmonary arterial pressure, limiting the diagnostic information of myocardial strain parameters in pulmonary hypertension.

Summary: The purpose of this study was to investigate the imaging characteristics and prognostic factors for the long-term survival of Behcet's disease (BD) with arterial involvement. The results showed that arterial lesions associated with BD usually involve multiple arteries and manifest differently in different types of arteries. Cardiac involvement and pulmonary artery aneurysm/dilation were independent prognostic factors for the survival of BD patients with arterial involvement.

Summary: This study investigated the potential of tin prefiltration and virtual monoenergetic imaging (VMI) in suppressing metal artifacts in high-resolution CT images of the lower extremities. The results showed that VMI reconstructions had better artifact reduction compared to T3D. VMI110keV had the least image noise. In terms of image quality, interpretability of bone-metal interface, and overall image quality, VMI110keV performed the best.

Summary: This study aimed to develop CT radiomics models to preoperatively identify lymph node (LN) status in resectable esophageal squamous cell carcinoma (ESCC) patients. The results showed that the combined model, integrating ESCC and LN radiomics features with clinical features, had the highest predictive ability among the three models. The combined model's predictive ability was validated in both the test and external validation cohorts.
