Summary: A novel joint histogram equalization (JHE) based technique is proposed in this research to improve the contrast of an image by utilizing the information among each pixel and its neighbors. The experimental analysis shows that this method outperforms the state-of-the-art histogram equalization algorithms in contrast enhancement, even for images with a narrow dynamic range.

Summary: In this article, an AI-powered radiomics algorithm based on slice pooling (AI-RASP) is proposed for glioma grading computer-aided diagnosis (CAD) system. AI-RASP generates compressed images for radiologists to manually segment, significantly reducing the time of manual segmentation. The results show that AI-RASP outperforms traditional manual segmentation in terms of performance and is over five times faster.

Summary: The study aimed to determine the role of ADC histogram analysis in identifying MYCN-amplification status in neuroblastomas. The results showed that ADC histogram analysis can differentiate between tumors with and without MYCN amplification, and can help identify areas for targeted biopsies or predict subtypes of high-risk tumors before biopsy results are available.

Summary: This study investigated the use of chest CT-based texture analysis in predicting overall survival (OS) in 98 patients with inflammatory breast cancer (IBC). Lower mean attenuation, MPP, and entropy on chest CT images were found to be significantly associated with worse OS, independent of clinicopathologic variables like M1 stage. These findings suggest that CT-based texture analysis could provide additional predictors for OS in IBC patients.

Summary: In this study, we propose an expert knowledge guided manifold representation learning (ENROL) framework for accurate glioma grading without relying on segmentation maps during testing. The framework constructs low-dimensional manifolds of handcrafted features and learned features to explore the implicit relationship between radiomics and deep learning, and to generate mutual consent representation for glioma grades. Results show that our framework can achieve promising glioma grading performance.

Summary: A method based on image histogram is proposed for quality inspection of 3D film images, which calculates the width of pixels for a specific height and classifies them based on a threshold. Experimental results show that the position of the height section of the image histogram achieves the highest classification accuracy. The proposed method demonstrates excellent classification accuracy for 3D film image classification compared to conventional algorithms.

Summary: Intracerebral hemorrhage is considered a major neurologic and neurosurgical emergency that requires timely diagnosis and treatment. A rare occurrence can involve an aneurysmal rupture presenting with isolated ICH. This study presents a case of a 48-year-old woman with ICH and MCA occlusion, ultimately uncovering a large MCA aneurysm treated with clipping.

Summary: This study found few modifiable risk factors for preventing cerebrospinal fluid leakage (CSFL) after intradural spine surgery. Patients with previous surgery at the index level had a higher risk of CSFL. The occurrence of CSFL resulted in more wound healing disorders and surgical site infections, requiring further treatment.

Summary: The management of asymptomatic intracranial meningiomas is controversial. This study aimed to assess growth predictors and develop clinical pathways for their management. The presence of calcifications and iso-/hyperintensity on T2-weighted imaging can stratify meningiomas as low, intermediate, or high risk, allowing for longer follow-up intervals for low and intermediate-risk tumors.

Summary: A standardized in vitro model was developed to test different grafts and suture techniques for watertight dural closure. The study found that there was no significant difference between running and simple interrupted suture techniques. Adding a patch or sealant resulted in higher hydrostatic burst pressure. The highest pressure was achieved with the combination of specific grafts and sealants.
