Technological developments in CT imaging, both hardware and software based, have led to a significant reduction in dose exposure in recent years. Over the past 12 years, there was a 73%, 54%, and 66% CTDI Vol reduction and a significant (p < 0.001) 72%, 33%, and 67% DLP reduction in assessing the paranasal sinuses for chronic sinusitis, preoperatively and posttraumatically, respectively.

Group comparisons were performed using either parametrical (ANOVA) or non-parametrical tests (Kruskal-Wallis Test), where applicable. Reconstruction techniques were filtered back projection and three generations of iterative reconstruction (IRIS, SAFIRE, ADMIRE, all from Siemens Healthineers). Scans were performed on three different CT scanners (Somatom Definition AS, Somatom Definition AS+, Somatom Force, all from Siemens Healthineers) and on one CBCT (Morita) ranging from 2010 to 2022. The computed tomography dose index (CTDI Vol) and dose length product (DLP) of a total of 1246 patients (average age: 41 ± 18 years, 361 females, 885 males) were evaluated, who received imaging of the paranasal sinuses either for chronic sinusitis diagnostic, preoperatively or posttraumatically. In this retrospective, single center patient study the radiation dose development in the past 12 years in CT imaging of the paranasal sinuses was assessed. I-Doser is a software used to listen binaural beats sequences (called "Doses") who will alternate your brain waves in order to simulate sensations or different mental states.Computed tomography (CT) has become the primary imaging modality for visualization of the paranasal sinuses. I-DOSER, a legal drug using sound and without any risk Don't forget to use a headset, it will help you feel the effects better. To launch a DOSE on the software, you have to click on "Load doses" (on the bottom left), then choose the desired DOSE and finally click on "Play Queue" (on the bottom right).

Launch the software with the downloaded DOSE and be prepared for the trip of your life ! Get the DOSE of your choice on our website (left menu)ģ. Download I-DOSER software for free by clicking one of the two links below :Ģ.
