Abnormalities in the blood circulation within organs such as the heart, liver and kidneys can be revealed with the use of contrast echography.
(PhysOrg. com) -- Contrast echography is a commonly used medical imaging technique that is used to show up abnormal blood circulation in organs and tumours.
This explains the sensitivity of contrast echography.
Until now it was assumed that this layer limited the echo, but now Marlies Overvelde of the University of Twente, The Netherlands, has shown that it is precisely the shell that determines the sensitivity of contrast echography.
Transvaginal echography is employed not only for diagnosing the pregnancy, but also for identifying abnormalities.
Viewing the Fetus: visual identification of the baby can occur via transvaginal echography at week six of the pregnancy, or through the abdomen at week eight.
Several robots equipped with preliminary versions of the robuBOX were already deployed: Estelle, the robot of tele-echography is in operation in 4 French hospitals, robuCAB, an automatic vehicle guided by GPS, as well as generic mobile platforms like the robuLAB10 for the assistance at home or the robuROC for safety.
Quantification of muscle volume by echography: Comparison with MRI data on subjects in long-term bed rest.
Recent studies have shown that transient echography or MRI elastography provide ways to assess liver fibrosis by non-invasively measuring liver stiffness in adult patients
• Imaging Studies: • If the media opacity prevents an appropriate fundus examination, echography with A-scan and B-scan may be helpful when evaluating the posterior pole.
