Comparative Study
Correlation between MRI and double-balloon urethrography findings in the diagnosis of female periurethral lesions.
This study aims to evaluate the correlation of MRI findings with double-balloon urethrography (DBU) in diagnosing female urethral diverticula and other periurethral lesions. In this retrospective study, females with clinically suspected periurethral lesions who underwent both MRI and DBU between 2008 and 2012 were evaluated. MRI was performed on a 1.5 Tesla unit using a pelvic phased array coil. ⋯ No periurethral lesion was found by either modality in 2 cases. The correlation between MRI and DBU in diagnosing female periurethral lesions is very good for anatomical delineation of diverticula. MRI, which does not involve radiation, may also indicate alternative diagnoses that can contribute to proper patient management.

To validate Fourier decomposition (FD) magnetic resonance (MR) imaging in cystic fibrosis (CF) patients with dynamic contrast-enhanced (DCE) MR imaging. ⋯ FD MR imaging provides equivalent diagnostic information to DCE MR imaging in CF patients. Automated assessment of regional perfusion defects using FD and DCE MR imaging is comparable to visual scoring but allows for percentage-based analysis.

Randomized Controlled Trial
Radiation dose reduction in soft tissue neck CT using adaptive statistical iterative reconstruction (ASIR).
To compare objective and subjective image quality in neck CT images acquired at different tube current-time products (275 mAs and 340 mAs) and reconstructed with filtered-back-projection (FBP) and adaptive statistical iterative reconstruction (ASIR). ⋯ Adapting ASIR into neck CT protocols reduced effective dose by 17% without compromising image quality.

Randomized Controlled Trial Comparative Study
Prospective randomized study of contrast reaction management curricula: computer-based interactive simulation versus high-fidelity hands-on simulation.
We developed a computer-based interactive simulation program for teaching contrast reaction management to radiology trainees and compared its effectiveness to high-fidelity hands-on simulation training. ⋯ It is feasible to develop a computer-based interactive simulation program to teach contrast reaction management. Trainees that underwent computer-based simulation training scored similarly on written tests and on a hands-on high-fidelity severe contrast reaction scenario performance test as those trained with hands-on high-fidelity simulation.
