Comparative Study
Comparison of intravoxel incoherent motion diffusion-weighted imaging between turbo spin-echo and echo-planar imaging of the head and neck.
To compare image quality, apparent diffusion coefficient (ADC), and intravoxel incoherent motion (IVIM)-derived parameters between turbo spin-echo (TSE)-diffusion-weighted imaging (DWI) and echo-planar imaging (EPI)-DWI of the head and neck. ⋯ • Head and neck DWI is especially sensitive to magnetic inhomogeneity. • The distortion of images was less with TSE-DWI than with EPI-DWI. • TSE-DWI can possibly exhibit higher ADC and IVIM-derived parameters than EPI-DWI. • Bland-Altman analysis showed unacceptable LoA in quantitative analysis between TSE-DWI and EPI-DWI. • It is not recommended to use both TSE-DWI and EPI-DWI for follow-up.

This study aimed to develop a test with validity evidence for abdominal diagnostic ultrasound with a pass/fail-standard to facilitate mastery learning. ⋯ • Ultrasound training can benefit from competency-based education based on reliable tests. • This simulation-based test can differentiate between competency levels of ultrasound examiners. • This test is suitable for competency-based education, e.g. mastery learning. • We provide a pass/fail standard without false-negative or false-positive scores.

To analyse the incidence and type of epidural steroid injection (ESI)-related adverse events, including procedure-related complications and drug-related systemic effects requiring hospitalisation or emergency room (ER) visits. ⋯ • The incidence of ESI-related events requiring hospitalisation was 0.46%. • The incidence of procedure-related complications was 0.026%. • The incidence of drug-related systemic effects was 0.11%. • The incidence of major complication of ESI was 0.011%. • The major complications were spine infection, haematoma, and sepsis.
