Ventilation Imaging of the Lung at 0.55T With Continuous Slice Cycling

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To propose and evaluate a novel method for pulmonary ventilation imaging, offering considerably improved SNR. Methods A continuous slice cycling (CSC) acquisition scheme is proposed to exclusively capture signal modulations from respiratory motion with increased SNR.

Next‐Generation Paleopathology: Using Commercial AI in Bioarchaeological Diagnosis

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Artificial intelligence encompasses computational systems capable of performing cognitive functions such as learning, reasoning, and problem‐solving. Within this domain, generative AI and large language models such as ChatGPT, Gemini, and Copilot have shown significant potential in clinical diagnostics.

Adult Langerhans cell histiocytosis with pulmonary and colorectoanal involvement: a case report

Journal of Medical Case Reports, 2017
Background Langerhans cell histiocytosis is a rare systemic disease characterized by the abnormal overproduction of histiocytes that tend to infiltrate single or multiple organ systems leading to significant tissue damage. It mainly affects – by order of

Genetic analysis of primary lung interdigitating dendritic cell sarcomas

The Journal of Pathology, EarlyView.
Abstract Interdigitating dendritic cell sarcomas (IDCSs) are rare tumors that commonly arise in the hematopoietic system and rarely outside. The genetic drivers of IDCS carcinogenesis are unknown; therefore, therapeutic options are limited. We investigated somatic gene mutations and copy‐number alterations (CNAs) in nine IDCSs arising in the lung by ...

Histiocytosis development and clinical variation through the lens of genomics

The Journal of Pathology, EarlyView.
Abstract Histiocytic neoplasms are rare haematologic diseases characterised by clonal expansions of cells with a monocyte, macrophage or dendritic cell phenotype. Their clinical manifestations are diverse, ranging from indolent lesions to aggressive systemic disease.

Genetic landscape of adult Langerhans cell histiocytosis with lung involvement

European Respiratory Journal, 2019
The clinical significance of the BRAFV600E mutation in adult Langerhans cell histiocytosis (LCH), including pulmonary Langerhans cell histiocytosis (PLCH), is not well understood. Similarly, the spectrum of molecular alterations involved in adult LCH has

Elderly male patient presenting with jaundice and cholangitis brings an unexpected histopathological finding, case report

Heliyon
In this report, we present a case of the first-time manifestation of Langerhans cell histiocytosis in the biliary tract of a 79-year-old male patient. Cholangiocarcinoma was the suspected diagnosis, based on the patient's painless jaundice.
