Nuclear Medicine & Radiation Therapy

Electronic radiation therapy is a type of cancer treatment that uses high-energy beams of electrons to destroy cancer cells. This therapy is also known as electron beam radiation therapy (EBRT). It works by delivering a focused beam of electrons to the tumor site, which damages the DNA of the cancer cells and prevents them from dividing and growing.

Gamma camera operators are exposed to ionizing radiation on a regular basis due to the nature of their work. Ionizing radiation can have harmful effects on human health, including an increased risk of cancer and genetic damage. Therefore, it is important to evaluate the exposure of gamma camera operators to ionizing radiation and take measures to minimize their exposure.

Electronic Medical Records (EMRs) have revolutionized the healthcare industry in recent years. EMRs refer to the digital versions of patients' medical charts that can be accessed and updated by authorized healthcare providers. The use of EMRs has transformed the way healthcare providers work and has improved the quality of care delivered to patients.

Radiopharmaceuticals are specialized drugs that contain radioactive isotopes and are used in the field of nuclear medicine for both diagnostic and therapeutic purposes. These drugs are designed to interact with specific organs or tissues in the body, allowing for precise imaging and treatment of a wide range of medical conditions.

It was aimed to make a dosimetric comparison by delivering the plans of patients treated with the robotic radiosurgery Cyberknife device using the density-adjusted radiotherapy (IMRT) technique in the treatment of non-small cell lung cancers (NSCLC) to the Helical Tomotherapy device. In cases where stereotactic body radiotherapy (SBRT) treatment cannot be performed in Cyberknife device, it is aimed to offer alternative treatment methods for NSCLC patients with the same cases.

In this study, the plans of 10 patients were evaluated retrospectively. For each of the 2 different techniques (Planned Target Volume), the minimum, maximum and average doses of PTV; homogeneity index and conformity index; the doses taken by the planned risky organs; the data of 20% and 50% isodoses and the statistical analysis of the values taken by the (monitor unit) were compared using the Social Sciences Statistical Package (SPSS) data analysis system. In the treatment of lung cancer patients, it was aimed to protect the critical organs at the maximum level; As Low as Reasonably Achievable principle optimization was achieved by irradiating the lesion at the destructive level.
