The "extended vision" approach to ultrasound evaluation calls for searching beyond predefined boundaries or specific organs in cases in which there is evidence of a pathologic condition that in itself is not sufficient for diagnosis. In a study of 300 consecutive cases referred for evaluation of a specific organ or area, the "extended vision" approach revealed unexpected findings in 34 cases, or 11% of the sample. Six of the cases are cited, demonstrating adult and fetal conditions unmasked by "extended vision" ultrasound, and practical considerations related to implementing a broad screening approach are discussed.
