  • Evaluation of Image Quality of Overweight and Obese Patients in CT Using High Data Rate Detectors
    Item type: Journal Article
    Feldmane, Idana; Gampp, Christian; Hausmann, Daniel; et al. (2023)
    In Vivo
    Background/Aim: To evaluate the impact of high data rate and sampling frequency detector technology compared to standard scan equipment on the image quality in abdominal computed tomography (CT) of overweight and obese patients. Patients and Methods: A total of 173 patients were retrospectively included in this study. Objective image quality in abdominal CT was evaluated using comparative analysis with new detector technology prior to market launch and standard CT equipment. Contrast noise ratio (CNR), image noise, volumetric computed tomography dose index (CTDIVol), and figures of merit (Q and Q1) were assessed for all patients. Results: Image quality was superior in the new detector technology for all parameters evaluated. The dose dependent parameters Q and Q1 showed a significant difference (p<0.001). Conclusion: A significant increase in objective image quality could be demonstrated using a new generation detector setup with increased frequency transfer in abdominal CT of overweight patients.
  • Can dynamic contrast-enhanced mri contribute to improved assessment of rectosigmoid involvement in deep infiltrating endometriosis?
    Item type: Journal Article
    Hausmann, Daniel; Perignon, Vasiliki; Grabherr, Regula; et al. (2021)
    In Vivo
    Background/Aim: To determine whether a prototypical compressed-sensing volume-interpolated breath-hold (csVIBE) provides diagnostic value in detecting rectosigmoid infiltration in deep infiltrating endometriosis (DIE). Patients and Methods: csVIBE was employed in 151 women undergoing pelvic magnetic resonance imaging, of whom 43 had undergone surgery for suspected endometriosis. The accuracy of T2-weighted BLADE and BLADE/csVIBE, additional diagnostic value of csVIBE, and diagnostic confidence were rated by two readers. Additionally, the presence of the “mushroom cap sign” was assessed on BLADE and csVIBE. Results: The diagnostic accuracy, sensitivity, and specificity of BLADE and BLADE/csVIBE were not significantly different between Readers A and B. For both readers, the confidence in the diagnosis increased with csVIBE, but this increase in the odds ratio was not significant for both readers. Both readers preferred csVIBE over BLADE with regard to detection of the “mushroom cap sign.” Conclusion: csVIBE.
