Summary: The study aimed to explore the effects of total-body PET/CT with half-dose F-18-FDG activity on image quality, and found that the image quality in the half-dose group was better than in the full-dose group. Through subjective and objective analyses, it was discovered that the image quality scores were higher in the half-dose group, and the liver signal-to-noise ratio was significantly higher as well.

Summary: The role of dual-phase FDG PET/CT in predicting the prognosis of operable breast cancer patients was investigated in this study. The combined parameters of SUVmax1 and RI on dual-phase FDG PET/CT were found to be useful for predicting disease-free survival and overall survival in breast cancer patients. Patients with a high SUVmax1 and a negative time course of FDG uptake had a favorable prognosis.

Summary: This study demonstrated that using Ga-68-PSMA-PET/CT for metastasis-directed treatment (MDT) of oligoprogressive lesions in CRPC patients with SBRT is effective and well-tolerated, prolonging the effectiveness of ADT by delaying the need for next-line systemic treatment (NEST).

Summary: This study evaluated the performance of FDG-PET-CT in distinguishing between local recurrence and post-radiation changes in patients with early-stage non-small cell lung cancer treated with stereotactic ablative radiotherapy. The positive predictive value of FDG-PET-CT in identifying local recurrence was found to be relatively low, especially at early post-treatment timepoints.

Summary: Background pre-treatment FDG-PET/CT scans were analyzed using machine learning to predict the progression and overall survival of lung malignancies. The study found that CNN models trained with FDG-PET/CT data performed well in predicting malignancy progression and overall survival. The prognostic models could potentially improve patient care and treatment options.

Summary: This study analyzed the clinical accuracy of F-18-FDG PET/CT in assessing treatment response in Burkitt lymphoma at the end of therapy. The results showed that using Deauville 5-point score as a cutoff point significantly related to progression-free survival and overall survival, with DS 5 being a better cutoff point for predicting recurrence or progression.

Summary: This study developed an automated lung tumor segmentation method for radiation therapy planning using deep learning and dual-modality PET-CT images. A 3D convolutional neural network was constructed to extract features and segment tumors based on PET and CT images. The network achieved clinically acceptable results on physician review after training and validation with a large dataset.

Summary: Radiomic models offer potential for improving the assessment of oesophageal adenocarcinoma through quantitative medical image analysis. However, the selection and generalizability of these models remain challenges. Although radiomic models show promise in predicting and distinguishing clinical features of oesophageal adenocarcinoma, further improvements in sensitivity and generalizability are needed. Future research should prioritize the prospective validation of proposed models to facilitate their clinical translation.

Summary: Dual-time-point F-18-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) can accurately differentiate a benign hemangioma from a metastasis. We present a case of a 70-year-old woman with a history of cervical carcinoma who underwent PET/CT to examine a chest wall tumor. The imaging showed moderate uptake of FDG in the tumor, which decreased in the delayed-phase scanning, indicating a benign hemangioma rather than a metastasis.

Summary: This study evaluated the prognostic value of F-18-fluorodeoxyglucose positron emission tomography with integrated computed tomography (F-18-FDG PET/CT) performed before and after concurrent chemoradiotherapy (CCRT) in esophageal cancer. The results showed that maximum SUV of PET/CT is useful in predicting prognosis of esophageal cancer patients treated with CCRT, especially when the initial SUV max exceeds 10. Small metabolic tumor volume and total lesion of glycolysis were also related to good prognosis. Efforts to find more effective treatments for patients at high risk of progression are still warranted.

Summary: This study aimed to investigate the prognostic significance of PET/CT-based radiomics signatures and clinical features in predicting local recurrence-free survival (LRFS) in nasopharyngeal carcinoma (NPC). A radiomics-clinical nomogram was developed using PET/CT images and clinical data from 726 patients. The nomogram showed good performance in predicting LRFS and distinguishing high-risk patients.

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.
