Introduction: In this diploma thesis we explored the principles of CT guided microwave ablation. We described an example of how the procedure is performed at the Clinic Golnik. Reviewing the literature on the topic, we discovered that the role of the radiological technologist is poorly defined, so our aim was to research the technologists purpose and tasks during the procedure, as well as their knowledge requrements. Purpose: The purpose of this thesis is describing the process of microwave ablation of a primary pulmonary tumour, based on a systematic review of literature as well as presenting a clinical case. Methods: We combined a systematic review of literature and descriptive method. We searched the following databases: Digital library of Slovenia, Digital library of University of Ljubljana, Cobiss, Google Scholar, Science Direct, PubMed, and Springer link. We expanded our knowledge about the procedure and the radiographer's role with a qualitative method, a correspondance with the radiographers working at Clinic Golnik. Results: With the intention of a better understanding of the procedure, we presented a clinical case of a patient, that was due to their underlying medical condition, an appropriate candidate for MWA. We provided the patient's history as well as documented procedure steps. We included images created during the procedure, as well as follow up CT images. Discussion and conclusion: We came to a conclusion that the procedure protocol at the Clinic Golnik is very similar to the procedures described in the literature. The main similarities are the preparation of the patient, patient selection, complications after the procedure and follow up care and imaging. We found some differences comparing technical parameters, use of ablation devices. The radiographer's role is assuring quality and safety of the ablation procedure, responsibility for the technological aspect, preparation of the patient for the procedure as well as assisting the radiologist during the procedure.
