Objective: Image-guided diagnosis and treatment of lung lesions is an active area of research. With the growing number of solutions proposed, there is also a growing need to establish a standard for the evaluation of these solutions. Thus, realistic phantom and preclinical environments must be established.

Methods: We retrospectively examined the MRI of 34 torsed adnexa of 34 cases. We specifically examined the peripherally displaced follicle sign, stromal edema, lack of stromal contrast enhancement, follicular rim sign, T2 hypointense rim sign, uterine deviation, adnexal displacement, whirlpool sign, T2 hypointense dot sign, and tubal thickening.
Violence risk is a major challenge among acute psychiatric inpatients. The study aimed to predict violent behavior risk in an acute psychiatric ward using video recordings from the emergency department. 69 videos of the emergency department recording the first ten minutes following patients' arrivals were included.

- GM1-gangliosidosis (GM1) causes significant brain degeneration, making it difficult to use automated MRI techniques for brain volume analysis. An effective standardized segmentation protocol was created to analyze MRIs from patients with type II GM1.
- A study involving 25 MRIs from 22 patients assessed the reliability of this segmentation method, focusing on various brain structures and evaluating the consistency between different raters.
- Results showed that the technique had good inter- and intra-rater reliability, especially for juvenile patients, which can enhance future research and understanding of the disease's progression over time.
Objectives: To determine whether idiopathic intracranial hypertension (IIH) may affect white matter integrity and optic pathways by using diffusion tensor imaging (DTI) and to correlate the DTI metrics with intracranial pressure (ICP).
Methods: This study is a retrospective case-control study. A total of 42 patients who underwent lumbar puncture and those with elevated ICP, meeting the diagnostic criteria for IIH, were included in the study.
