Still not convinced?
Standardized imaging protocols and storage of all exam information are routine in virtually all imaging modalities except general ultrasound (US).
For technical reasons, clinicians and radiologists of the past have been limited to the examiners bedside perception of pathology, still images based on this perception, and written reports.
For reasons of traditions, US is still performed the same way almost everywhere despite the technical developments in recent years.
It is well known that the lack of strict exam standardization and selective still imaging - regardless of the amount of still images per exam - is a severe obstacle to dependable re-evaluation of exams.
Without complete standardized cine documentation, comparison with previous exams is in effect restricted to comparison with the previous reports!
Nobody would dream of scrolling through CT exams at the monitor at the CT lab, saving a few slices, erasing the rest and then writing a report. But this is exactly what is done in the US departments.
Our experience since 1999, when we began developing Sonodynamics, has proven to us that all US examiners occasionally overlook important information that is conspicuous on the machine's monitor - information that can be preserved and discovered by the use of a strict and regular cine documentation technique.
Contrast enhanced ultrasound (CEUS) really pinpoints the shortcomings above by introducing a new aspect: The time factor.
In addition to the large amount of information that actually is in conventional US, CEUS also provides information that rapidly changes with the circulatory phases of the target organ.
With CEUS it becomes evident that US documentation needs to be taken to a more dependable level than that of still images and paper reports alone, for the full utility of this marvellous modality!
