Summary: This study found that there were almost no significant differences in the detectability and visibility of cystic lesions between low-dose CBCT imaging and the standard protocol. Both imaging protocols showed similar performance in lesion size assessment, but with an underestimation of the actual size.

Summary: A significant reduction in effective dose for CBCT-DCG in healthy volunteers is achievable by decreasing the scanning field of view (FOV) without compromising diagnostic capability. CBCT-DCG is a potential first-line imaging test for evaluating the lacrimal drainage system, allowing for functional assessment of lacrimal drainage.

Summary: The purpose of this study was to determine a conversion formula between dose-area product (DAP) and effective dose (E) for dental CBCT. They simulated CBCT exposures of an adult phantom and used multiple linear regression to fit the formula. The formulas showed high accuracy and could be categorized based on the size of the field of view (FOV).

Summary: We propose a motion estimation and motion correction approach for oral and maxillofacial cone beam CT scans based solely on 2D projection images. This algorithm improves the visualization quality of motion impaired scans, eliminating the need for re-scans and reducing radiation dosage for patients.

Summary: This study evaluated the diagnostic accuracy of fused CBCT images for patients with condylar bone resorption of temporomandibular joint osteoarthrosis. The results showed that fused CBCT images can intuitively display the condylar bone resorption and significantly improve the diagnostic accuracy.

Summary: The study analyzed the variation in orthodontic diagnostic measurements on lateral cephalograms reconstructed from ULD-LD CBCT scans compared to standard lateral cephalograms. Results showed that there were small differences in variation between the two imaging methods, supporting the use of ULD-LD CBCT with reconstructed lateral cephalograms for orthodontic diagnostic purposes due to the lower radiation dose.

Summary: This study retrospectively reviewed 336 cone-beam CT-guided percutaneous transthoracic needle biopsy procedures in 326 patients and found that the target lesion size was the only significant predictor of diagnostic failure, while complications occurred at a reasonable rate.

Summary: This study compared the image quality produced by equivalent low-dose and default imaging protocols of a conventional dental CBCT scanner, an extremity CBCT scanner, and a clinical MDCT scanner. The results showed that the dental CBCT had superior performance over the extremity CBCT in all studied parameters, while the MDCT had better contrast-to-noise ratio, low contrast visibility, and image uniformity than the CBCT scanners. However, the CBCT scanners had better resolution compared to the MDCT. The accuracy of HU values was similar between the dental CBCT and MDCT, but the extremity CBCT had substantially poorer performance.

Summary: This study evaluated the accuracy of an optimized CBCT protocol for the detection of intraoperative endodontic complications. The results showed that there were no significant differences in accuracy, sensitivity, specificity, and area under the receiver operating characteristic curve between the dose protocols, regardless of the presence of metallic materials.

Summary: This report investigated the image reject rates of intra-oral, extra-oral, and CBCT imaging, finding different rejection rates for different types of images, with positioning error and patient movement being the main reasons for rejection. The study suggests that future reject analysis studies should report more radiographic parameters to improve the reference values for quality assurance programs.

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: The ability of pretreatment PET parameters and peripheral blood biomarkers to predict PFS and OS in NSCLC patients treated with ICIT was assessed. The study found that MTV and the number of SOI were independent risk factors for progression and overall survival, and the combination of these factors improved risk stratification.

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.
