Comparison of diffusion-weighted whole-body magnetic resonance imaging and abdominal ultrasonography versus contrast-enhanced computed tomography in diagnosing acute focal bacterial nephritis: a retrospective cohort study

DWIBS demonstrated promising diagnostic accuracy for AFBN compared with abdominal ultrasonography, suggesting it could be a valuable diagnostic tool for this condition. Given its diagnostic accuracy, DWIBS may be considered over abdominal ultrasonography in patients who are unable to undergo contrast-enhanced CT due to allergies or pregnancy. However, further prospective studies with larger sample sizes are necessary to validate these findings.
