Background: Depersonalization-Derealization Disorder (DPRD) presents challenges in understanding its neurobiological underpinnings. Several neuroimaging studies have revealed altered brain function and structure in DPRD. However, the knowledge about large-scale dysfunctional brain networks in DPRD remains unknown.

The uncommon growth of cells in the brain is termed as brain tumor. To identify chronic nerve problems, like strokes, brain tumors, multiple sclerosis, and dementia, brain magnetic resonance imaging (MRI) is normally utilized. Identifying the tumor on early stage can improve the patient's survival rate.

Background: Sometimes, the identification of ground-glass opacities (GGOs), small or deep pulmonary nodules can be difficult also in expert hands. Usually for these lesions pulmonary lobectomy is an overtreatment, so we developed a technique to identify easily these nodules. The objective of this research is to assess the effectiveness and safety of using preoperative cone beam computed tomography (CBCT) to guide the placement of micro-coils in the lung parenchyma near GGO and small lesions.

Introduction: Radiography and medical students (RMS), upon graduation, require capabilities to provide life-saving care through identification and communication of urgent findings on radiological imaging. This preliminary study investigated RMS' ability to identify and categorise urgent findings on CT examinations. It also explored their experiences of image interpretation education.

Brats-Toolkit and DeepBraTumIA generally provide accurate segmentations, particularly for the most common round-shaped or well-demarked tumors, where: (1) gross tumor segmentation correctly includes necrosis and contrast enhanced tumor in 100% and 97.
