Medicina Nuclear e Radioterapia

Nuclear medicine often contain regions with limited oxygen supply (hypoxia), which are more resistant to radiation. Radiosensitizers can help overcome this resistance by improving oxygen levels in tumor tissues The meticulously analyse of the images to identify the tumor's precise location and the location of critical structures. After identifying the target volume and critical structures, dosimetrists use specialized software to calculate the optimal distribution of radiation dose.

Molecular imaging represents a paradigm shift in the realm of medical diagnostics, offering a deeper understanding of cellular activity in health and disease. In nuclear medicine, this cutting-edge approach utilizes radiopharmaceuticals and advanced imaging techniques to visualize molecular processes within the body. This article explores the significance of molecular imaging, its applications and the transformative impact it has on healthcare. The foundation of molecular imaging lies in radiopharmaceuticals compounds that combine a radioactive isotope with a biologically active molecule. These molecules can selectively bind to specific cellular targets, allowing the visualization of molecular processes.

Radioactive tracers make them powerful tools in medical diagnostics, offering insights into the function, structure and metabolism of organs and tissues. Unlike traditional imaging methods that focus on anatomy, nuclear medicine primarily provides functional information. Radioactive tracers can be designed to target specific tissues or organs based on their physiological characteristics. This targeted approach enhances the specificity of diagnostic imaging, providing detailed information about the area of interest. Radiopharmaceuticals are used to detect abnormalities or changes in the function of organs and tissues This article explores the significance of molecular imaging, its applications and the transformative impact it has on healthcare. The foundation of molecular imaging lies in radiopharmaceuticals compounds that combine a radioactive isotope with a biologically active molecule. These molecules can selectively bind to specific cellular targets, allowing the visualization of molecular processes.

Multidisciplinary healthcare involves professionals from various fields working together to develop personalized treatment plans for each patient. In the context of cancer, this often includes medical oncologists, surgical oncologists, radiation oncologists, radiologists, pathologists and other specialists. Before initiating radiation therapy, a thorough assessment of the patient's medical history, diagnostic imaging and pathology results is essential. The meticulously analyse of the images to identify the tumor's precise location and the location of critical structures. After identifying the target volume and critical structures, dosimetrists use specialized software to calculate the optimal distribution of radiation dose.
