A brief history of positron emission tomography (PET)

Seminars in Nuclear Medicine, 1998
The development of positron emission tomography (PET) illustrates how advances in basic science translates into benefits for human beings. In 1930 Ernest Lawrence and co-workers conceived of the cyclotron. By 1938 Lawrence, Livingston, et al had designed a "medical cyclotron." The subsequent production of C-11, N-13, O-15, and F-18 found many uses in ...

Clinically Informed Intelligent Classification of Ovarian Cancer Cells by Label‐Free Holographic Imaging Flow Cytometry

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Quantitative phase maps of single cells recorded in flow cytometry modality feed a hierarchical architecture of machine learning models for the label‐free identification of subtypes of ovarian cancer. The employment of a priori clinical information improves the classification performance, thus emulating the clinical application of liquid biopsy during ...

Thermal Properties of 18F-FDG Uptake and Imaging in Positron Emission Tomography Scans of Cancerous Cells [PDF]

, 2021
Positron Emission Tomography (PET) scans can utilize a radioactive tracer, in this case 2-deoxy2-[fluorine-18] fluoro-D-glucose (18F-FDG), to visualize malignant tumors in cancer patients.

A Hybrid Transfer Learning Framework for Brain Tumor Diagnosis

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
A novel hybrid transfer learning approach for brain tumor classification achieves 99.47% accuracy using magnetic resonance imaging (MRI) images. By combining image preprocessing, ensemble deep learning, and explainable artificial intelligence (XAI) techniques like gradient‐weighted class activation mapping and SHapley Additive exPlanations (SHAP), the ...

The Role of Glutamatergic and Dopaminergic Genes in Resistant Schizophrenia: A Systematic Review

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Psychosis is a heterogeneous disorder, with approximately one‐third of patients experiencing treatment resistance, predominantly among individuals diagnosed with Schizophrenia. Treatment‐resistant schizophrenia (TRS) may stem from a distinct biological signature, involving abnormalities in the dopaminergic and glutamatergic systems.

Nasal Tuft Cell Markers Are Predictive of Overall Survival in Sinonasal Neuroendocrine and Sinonasal Undifferentiated Carcinomas

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Sinonasal neuroendocrine carcinoma (SNEC) and sinonasal undifferentiated carcinoma (SNUC) are rare aggressive malignancies with no established prognostic markers. Because features of POU2F3+ small cell lung carcinomas have been identified in both tumors, we evaluated immunostaining for POU2F3, a tuft cell transcription factor, and ...

PSMA PET in Favourable Intermediate-Risk Prostate Cancer? Gold Mine or Money Pit

Société Internationale d’Urologie Journal
Background/Objectives: Since the proPSMA trial, prostate-specific membrane antigen (PSMA) positron emission tomography (PET) scan has primarily replaced conventional imaging for staging newly diagnosed prostate cancer. The objective of this commentary is
