Complicated Acute Appendicitis Conservatively Treated in Two Patients With Crohn's Disease: The Role of Intestinal Ultrasound and Contrast‐Enhanced Ultrasound

Journal of Clinical Ultrasound, EarlyView.
Intestinal ultrasound and contrast‐enhanced ultrasound were used to diagnose, monitor, and guide conservative treatment of complicated acute appendicitis in two patients with Crohn's disease. Serial imaging enabled early identification of treatment response, allowing long‐term surgery‐free outcomes.

Australia's Three System Approach to Mammographic Image Quality Assessment

Journal of Medical Radiation Sciences, EarlyView.
Mammographic image evaluation in Australia remains constrained by the use of fragmented, subjective, and largely unevaluated systems. The continued use of the Perfect (P), Good (G), Moderate (M), Inadequate (I) (PGMI) image evaluation system (IES) framework despite concerns around its validity and reliability reflects a perceived practical utility and ...
