Automatic Tumor Segmentation via False Positive Reduction Network for Whole-Body Multi-Modal PET/CT Images [PDF]
arXiv, 2022 Multi-modality Fluorodeoxyglucose (FDG) positron emission tomography / computed tomography (PET/CT) has been routinely used in the assessment of common cancers, such as lung cancer, lymphoma, and melanoma. This is mainly attributed to the fact that PET/CT combines the high sensitivity for tumor detection of PET and anatomical information from CT.

SDHD gene mutation in Mexican population with carotid body tumor.
Cirugía y Cirujanos, 2019 Introduction Among the U.S. population, the p81L SDHD (11q23) gene mutation is present in 6-36% of patients with sporadic carotid body tumor (CBT), but in familial cases is high as 80%.

Advanced Science, EarlyView.The present study shows that macrophage WEE1 drives NF‐κB activation and inflammatory atherosclerosis by directly phosphorylating p65 at S536. This finding illustrates a macrophage‐specific WEE1‐p65 axis in regulating inflammatory atherosclerosis and points out new directions to broaden the clinical applications for WEE1 inhibitors in atherosclerosis ...

A Localization-to-Segmentation Framework for Automatic Tumor Segmentation in Whole-Body PET/CT Images [PDF]
arXiv, 2023 Fluorodeoxyglucose (FDG) positron emission tomography (PET) combined with computed tomography (CT) is considered the primary solution for detecting some cancers, such as lung cancer and melanoma. Automatic segmentation of tumors in PET/CT images can help reduce doctors' workload, thereby improving diagnostic quality. However, precise tumor segmentation

Clonal Hematopoiesis and Thrombosis
American Journal of Hematology, EarlyView.ABSTRACT Clonal hematopoiesis (CH) has been the focus of many research efforts in the last years and has emerged as a risk modifier for cardiovascular disease morbidity and mortality. While substantial evidence has accumulated regarding its impact on arterial system diseases, the connection with venous thrombosis has only recently been explored.

Segmentation of brain tumor on magnetic resonance imaging using a convolutional architecture [PDF]
arXiv, 2020 The brain is a complex organ controlling cognitive process and physical functions. Tumors in the brain are accelerated cell growths affecting the normal function and processes in the brain. MRI scans provides detailed images of the body being one of the most common tests to diagnose brain tumors.

Alzheimer's &Dementia, EarlyView.Abstract US clinical practice guidelines for the diagnostic evaluation of cognitive impairment due to Alzheimer's disease (AD) or AD and related dementias (ADRD) are decades old and aimed at specialists. This evidence‐based guideline was developed to empower all—including primary care—clinicians to implement a structured approach for evaluating a ...

A cascaded deep network for automated tumor detection and segmentation in clinical PET imaging of diffuse large B-cell lymphoma [PDF]
Proc. SPIE 12032, Medical Imaging 2022: Image Processing, 120323M
(4 April 2022)Accurate detection and segmentation of diffuse large B-cell lymphoma (DLBCL) from PET images has important implications for estimation of total metabolic tumor volume, radiomics analysis, surgical intervention and radiotherapy. Manual segmentation of tumors in whole-body PET images is time-consuming, labor-intensive and operator-dependent. In this work,

Impact of hyperoxia and phenylephrine on cerebral oxygenation: An experimental clinical study
Acta Anaesthesiologica Scandinavica, Volume 67, Issue 1, Page 57-65, January 2023., 2023 Abstract Background Oxygen supply to the brain is of special importance during intracranial surgery because it may be compromised by intracranial pathology. A high arterial blood pressure (mean arterial pressure above 80 mmHg) and a high arterial oxygen tension (PaO2 above 12 kPa) is therefore often targeted in these patients, when for example ...
