An octreotide scan, also known as an octreotide scintigraphy or somatostatin receptor scan, is a type of nuclear medicine imaging test used to evaluate certain types of tumors, particularly neuroendocrine tumors. The procedure involves the use of a radiolabeled form of octreotide, a synthetic version of the natural hormone somatostatin, which binds to somatostatin receptors that are often overexpressed in neuroendocrine tumors.

Optical Coherence Elastography (OCE) is an advanced imaging technique that combines principles of optical coherence tomography (OCT) with elastography to assess the mechanical properties of biological tissues. This technology is particularly useful in the field of medical diagnostics as it provides both structural and functional information about tissues. ### Key Features of Optical Coherence Elastography: 1. **Imaging Technique**: OCE utilizes light to derive images of tissue microstructures at very high resolutions.

Orthanc is an open-source DICOM (Digital Imaging and Communications in Medicine) server designed for the storage, retrieval, and management of medical imaging data. It is developed to provide a lightweight, flexible, and high-performance solution for handling DICOM files and related resources. Here are some key features and characteristics of Orthanc: 1. **Open-Source**: Orthanc is available under an open-source license, allowing users to download, modify, and contribute to its development.

Orthogonal Polarization Spectral (OPS) imaging is a technique used primarily in biomedical imaging to obtain high-resolution images of biological tissues. It is particularly valuable in the visualization of microvascular structures and dynamic processes in living tissues. The key features of OPS imaging include: 1. **Polarization**: OPS imaging utilizes polarized light to enhance contrast and reduce background noise. By using two orthogonal polarization states of light, the technique can differentiate between various types of tissue structures based on their optical properties.

PI-RADS, or the Prostate Imaging Reporting and Data System, is a standardized system used to assess and report the findings of prostate magnetic resonance imaging (MRI). Developed by the American College of Radiology (ACR) and the European Society of Urogenital Radiology (ESUR), PI-RADS aims to provide a consistent method for interpreting prostate MRI to aid in the detection and characterization of prostate cancer.

Particle-induced gamma emission (PIGE) is a nuclear analytical technique used to study the composition of materials by analyzing the gamma rays emitted when a target material is bombarded with high-energy particles, typically protons or alpha particles. The technique is based on the principle that when the high-energy particles collide with the nuclei of the atoms in the target material, they can cause nuclear reactions that result in the emission of gamma rays.
