  Native Tissue Harmonic Imaging may be as significant a development in the history of ultrasound as color Doppler , said Philip W. Ralls , MD , professor of radiology , Los Angeles County/University of Southern California Medical Center.He said that the technology provides images superior to conventional ultrasound in about 80 to 90 % of patients , especially difficult-to-image patients. Acuson estimates that these patients may comprise 20 to 30 % of those referred for ultrasound studies.
  
  Microsonography performed with high-resolution transducer.
  
  Acuson also displayed its 15L8w , part of the MICROSON high-resolution transducer family , as a work-in-progress.

  Yes, said Dr. Philip Ralls, professor of radiology at the Keck School of Medicine, University of Southern California in Los Angeles.
  
  "Why would you go for ultrasound, an insensitive test that is technically difficult, versus CT scanning, which is a sensitive test that requires less expertise?"Ralls asked.
  
  Ralls noted ultrasound's lack of sensitivity; a negative FAST ultrasound scan does not exclude pathology, he said.A patient initially imaged with ultrasound will likely remain in the hospital for observation and will still have to undergo a CT scan if their condition worsens -- an expensive proposition compared to immediate CT scanning, which clears many patients for discharge, Ralls said.
  
  While Ralls and McGahan agreed that there is a role for FAST ultrasound in the modern trauma center, for the time being, physician preference will determine which modality is used first.
