Summary: This study proposes a straightforward simulation approach based on superposed Wave (s-Wave) to accelerate photoacoustic simulation. By manipulating the phase and amplitude of sensor data, the computation time is significantly reduced. The results show that s-Wave exhibits a speed improvement >2000 times compared with k-Wave in a sparse system configuration, and in terms of optimization-based image reconstruction, the reconstruction time is reduced by approximately 50 times.

Summary: This study introduces a fully automated, real-time method for measuring left atrial volume in echocardiography using a neural network to identify key time points and segmentation techniques. The results show that this method provides comparable accuracy to manual measurements while saving time and reducing operator variability, with an average volume difference of 2.9 mL for 2-D and 7.8 mL for 3-D imaging. The application of pseudo-labeling improves the stability of volume curves and the accuracy of end-systole measurement.

Summary: Hepatic arterial infusion pumps allow selective administration of chemotherapy to the liver, maximizing its effects while minimizing systemic toxicity. Radiologists play a crucial role in pre-operative planning, treatment response assessment, and evaluation of potential complications. This article aims to familiarize radiologists with various aspects of HAI pumps.

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 evaluated and compared the diagnostic value of diffusion-related texture analysis parameters from different magnetic resonance diffusion models in predicting the clinical response to chemotherapy in patients with colorectal liver metastases. Among the models, DKI-derived parameters showed the best performance for early prediction, followed by IVIM-derived parameters and DWI baseline features.

Summary: This study compared the performance of the current PotD strategy with non-adaptive and fully online-adaptive techniques in the treatment of cervical cancer patients. The findings show that the PotD protocol is effective in improving normal tissue sparing compared to no adaptation, while fully online-adaptive approaches can further reduce target volume but come with a more complex workflow.

Summary: This paper analyzes the correlation between imaging features and ECG features in patients with coronary artery fistula (CAF). The study finds significant differences in ECG characteristics between coronary-cameral fistula (CCF) and coronary-pulmonary artery fistula (CPAF). Surgical treatment can improve ECG findings in some patients.

Summary: Survival analysis is a valuable tool in healthcare for predicting the time to specific events. This paper introduces CenTime, a novel approach that directly estimates the time to event. The method performs well with censored data and can be easily integrated with deep learning models. Compared to standard methods, CenTime offers superior performance in predicting event time while maintaining comparable ranking performance.

Summary: This study examines the use of GPT-4 in monitoring radiation toxicity during prostate cancer treatments. Two methods, summarization and chatbot interface, were tested. Radiation oncologists surveyed preferred the summarization method for its accuracy and potential for adoption, and both methods saved time.

Summary: This study investigated the accuracy and limitations of theoretical corrections in neutron-induced reactions on isotopically enriched Ge targets. Experimental cross-section measurements were conducted on several reactions using Ge-nat and isotopically enriched Ge targets. The results showed that the methodology using isotopically enriched targets provided accurate results without the need for theoretical corrections.

Summary: PI-RADSv2.1 made important modifications for the assessment of category 3 lesions, with a small impact. The combination of PSAD is the most likely approach to aid in clinical decision making for PI-RADS 3 category. Commercially available fluidic markers are being used to supplement this, but further evidence is needed to improve the accuracy of PI-RADS alone in detecting csPCa.
