Physical and Technical Constraints The most significant ultrasound limitations stem from the physics of sound wave propagation. Image quality is also directly dependent on the depth of the target; as the beam travels deeper, resolution decreases, potentially obscuring fine details in larger patients.

These ambiguities necessitate follow-up testing or correlation with other imaging modalities. Unlike radiation-based imaging, sound waves travel poorly through air and gas, creating significant artifacts when visualizing structures behind the lungs or bowel.
There is no standardized "autopilot" setting that guarantees consistent results across different operators. However, when the acoustic windows are poor or the clinical suspicion remains high despite a negative scan, clinicians must be prepared to utilize CT, MRI, or laboratory tests to reach a definitive conclusion.

Results heavily influenced by patient body habitus. The lungs and brain are generally inaccessible to standard external ultrasound because of the rib cage and skull, respectively.
