Abstract

Interventional radiology, although a relatively new subspecialty of radiology, comes to provide a solution in the modern era where there is a need for minor interventions (such as biopsies and punctures) but not the necessary time and often not even the available resources. It is a widespread method, which can be performed with all imaging methods, making it an accessible and available solution in every corner of the globe and in all social classes, while covering a variety of procedures that reduce the need for major surgery. The purpose of this paper is to investigate interventional procedures, specifically the ones guided by computed tomography, the techniques that are used, the equipment, as well as the benefits over other techniques that are traditionally used. A very important part of the paper concerns the pitfalls which the invasive staff can come across during the execution of an operation. Performing operations without adequate planning can lead to serious side effects and for this reason specific safety measures have been instituted as well as lists of instructions in order to optimize practices. In addition, the received radiation dose is studied, both by the patient and staff. The dose of radiation received is a very important parameter, which must always be taken into account when planning operations based on existing protocols, applicable law and always be patient-oriented. Finally, reference is made regarding the importance of the role of the radiologic technologist in the conduct of invasive procedures.
