About POCUS Corner
Each topic page reviews the diagnostic evidence for point-of-care ultrasound in a specific clinical scenario. Sensitivity and specificity are reported against a reference standard (CT, formal echo, catheterization, or biopsy). Limitations are discussed with equal weight as benefits — including operator dependence, acoustic window constraints, and conditions that reduce specificity. Comparison tables summarize POCUS vs. chest X-ray, CT, and MRI where data exist.
