The psychological anxiety of radiologists, as well as the patients, is growing with the increasing use of CT contrast agent side effects and the process of extravasation. In this study, a satisfaction survey was conducted regarding the wireless signal device after CT examination in patients and radiologists by employing a wireless signal device during a contrast-enhanced CT examination in order to determine its usefulness to the relieve psychological anxiety, such as anxiety and fear, of patients and radiologists when using contrast agents. The use of a wireless signal device was also intended to help radiologists in dealing with the side effects of contrast agents that may occur during a CT examination and preventing extravasation. Patients aged 20 years or older, who visited the C university hospital in Jeonnam province for 4 months from August to November in 2017, were surveyed. A total number of 90 patients (57 males and 33 females),who agreed to the study after CT examination, were included in the questionnaire survey. Meanwhile, 15 radiologists, who were working at a CT room and had an experience in using a wireless signal device, were surveyed. Patient satisfaction was 6.01±0.88 before the use of a wireless signal device and 8.20±1.06 after use, thereby showing an increased satisfaction after its use. Radiologist satisfaction was 8.46±1.06 after use, thereby not showing a big difference from the mean patient satisfaction. The satisfaction was high at over 8 points in both groups. The contribution to psychological stability with the use of a wireless signal device was 8.98±0.65 in patients with prior experience of side effects and 8.00±1.21 in patients without prior experience of side effects. In conclusion, it is considered to improve satisfaction with the examination by helping the radiologists in taking immediate action with calling via the wireless signal device and providing the patients and radiologists with psychological stability by reducing their anxiety.
