DIOSMS is an acronym that stands for "Direct Intra-Operative Single-Photon Emission Computed Tomography," referring to a medical imaging technique used during surgical procedures. It combines two methods, namely single-photon emission computed tomography (SPECT) and intra-operative localization, to provide real-time imaging of physiological processes and functional information within the body.
The DIOSMS technique involves injecting a radioactive tracer into the patient's bloodstream, which selectively accumulates in the target tissue. During the surgical procedure, a specialized gamma camera is used to detect the emitted gamma rays from the tracer. These gamma rays are then converted into detailed three-dimensional images using computed tomography (CT). This allows surgeons to visualize the target tissue and surrounding structures, aiding in precise identification, localization, and assessment of the area of interest during the operation.
The real-time imaging capabilities of DIOSMS enable surgeons to make informed decisions, such as determining the exact location and extent of tumors, assessing blood flow, and evaluating tissue viability. It enhances surgical accuracy and reduces the likelihood of complications by providing valuable live feedback during the procedure.
DIOSMS has particularly proven useful in various fields of surgery, including neurosurgery, cardiovascular surgery, and oncology. Its ability to provide functional imaging helps improve surgical outcomes, minimize damage to healthy tissue, and potentially shorten the duration of operations.
In summary, DIOSMS is a medical imaging technique that integrates SPECT and intra-operative localization, offering real-time functional imaging during surgeries and assisting surgeons in accurate tissue identification and assessment.
