MRI in pregnant patients with suspected abdominal and pelvic cancer: a practical guide for radiologists

open access: yesDiagnostic and Interventional Radiology, 2020
The incidence of abdominal and pelvic cancer in pregnancy is low, but it is rising as the population of pregnant women gets older. Depending on disease stage, gestational age and patient’s preference, active surveillance as well as surgery and ...

A case of a small-sized cavernous hemangioma in the right ventricle - an incidental finding

open access: yesRadiology Case Reports, 2022
A cardiac cavernous hemangioma is a rare, primary, benign tumor that is usually diagnosed in young or middle-aged patients. In this article, we report the case of a 71-year-old male patient whose doctors incidentally discovered a heart tumor on his ...

Evolutionary interplay between viruses and R‐loops

open access: yesFEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Mammography breast density assessment with Quantra artificial intelligence software: intra- and interobserver agreement with radiologists

open access: yesJournal of the Mexican Federation of Radiology and Imaging
Introduction. A new version of Quantra v.2.2.2 artificial intelligence (AI) software is used for mammography breast density (MBD) assessment. This study aimed to determine the intraobserver agreement of radiologists (human readers, HRs) and the ...

Biological and technical complexities in analyzing extracellular vesicle immune interactions in B‐cell malignancies

open access: yesFEBS Letters, EarlyView.
Extracellular vesicles (EVs) mediate intercellular communication in tumor immune microenvironments. However, their role in B‐cell malignancies remains poorly defined, owing to biological complexity and technical challenges in EV isolation and analysis.

Towards Standardized Language to Describe the Pathological Enhancement of the Nipple in NAC-Infiltrating Breast Tumors: A Retrospective Case Series Study

open access: yesDiagnostics
Background: The normal pattern of nipple enhancement on magnetic resonance imaging (MRI) is defined based on healthy individuals, as it correlates with the structural anatomy of the nipple–areola complex (NAC).

Immunotargeting of Integrin αβ for Single-Photon Emission Computed Tomography and Near-Infrared Fluorescence Imaging in a Pancreatic Cancer Model

open access: yesMolecular Imaging, 2016
To explore suitable imaging probes for early and specific detection of pancreatic cancer, we demonstrated that α 6 β 4 integrin is a good target and employed single-photon emission computed tomography (SPECT) or near-infrared (NIR) imaging for ...

Diagnostic Imaging in COPD [PDF]

open access: yesSeminars in Respiratory and Critical Care Medicine, 2010
Chronic obstructive pulmonary disease (COPD) is a pathological pulmonary condition characterized by expiratory airflow obstruction due to emphysematous destruction of the lung parenchyma and small airways remodeling. Although spirometry is a very useful diagnostic tool for screening large groups of smokers, it cannot readily differentiate the ...

The epithelial barrier theory proposes a comprehensive explanation for the origins of allergic and other chronic noncommunicable diseases

open access: yesFEBS Letters, EarlyView.
Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...
