Brain tumor multi classification and segmentation in MRI images using deep learning [PDF]
arXiv, 2023 This study proposes a deep learning model for the classification and segmentation of brain tumors from magnetic resonance imaging (MRI) scans. The classification model is based on the EfficientNetB1 architecture and is trained to classify images into four classes: meningioma, glioma, pituitary adenoma, and no tumor.

Recurrent Acromegaly in a Patient With a CHEK2 Mutation
AACE Clinical Case Reports, 2022 Background/Objective: CHEK2 is a cell-cycle checkpoint kinase and is part of the ATM-CHEK2-p53 cascade, which is protective against carcinogenesis. We describe a germline CHEK2 mutation in a patient with acromegaly and other tumors.

Pituitary tumors contain a side population with tumor stem cell-associated characteristics.
Endocrine-Related Cancer, 2015 Pituitary adenomas cause significant endocrine and mass-related morbidity. Little is known about the mechanisms that underlie pituitary tumor pathogenesis.

Preoperative Volume Determination for Pituitary Adenoma [PDF]
, 2016 The most common sellar lesion is the pituitary adenoma, and sellar tumors are approximately 10-15% of all intracranial neoplasms. Manual slice-by-slice segmentation takes quite some time that can be reduced by using the appropriate algorithms. In this contribution, we present a segmentation method for pituitary adenoma.

Template-Cut: A Pattern-Based Segmentation Paradigm [PDF]
, 2012 We present a scale-invariant, template-based segmentation paradigm that sets up a graph and performs a graph cut to separate an object from the background. Typically graph-based schemes distribute the nodes of the graph uniformly and equidistantly on the

Incident Angle Study for Designing an Endoscopic Tool for Intraoperative Brain Tumor Detection [PDF]
arXiv, 2023 In neurosurgical procedures maximizing the resection of tumor tissue while avoiding healthy tissue is of paramount importance and a difficult task due to many factors, such as surrounding eloquent brain. Swiftly identifying tumor tissue for removal could increase surgical outcomes.

How to Classify Pituitary Neuroendocrine Tumors (PitNET)s in 2020
Cancers, 2020 Adenohypophyseal tumors, which were recently renamed pituitary neuroendocrine tumors (PitNET), are mostly benign, but may present various behaviors: invasive, “aggressive” and malignant with metastases.

QuickTumorNet: Fast Automatic Multi-Class Segmentation of Brain Tumors [PDF]
arXiv, 2020 Non-invasive techniques such as magnetic resonance imaging (MRI) are widely employed in brain tumor diagnostics. However, manual segmentation of brain tumors from 3D MRI volumes is a time-consuming task that requires trained expert radiologists. Due to the subjectivity of manual segmentation, there is low inter-rater reliability which can result in ...
