Non-cardiac imaging
The following non-cardiac contrast acquisition applications are
available.
• Vascular Contrast imaging: optimized to visualize
contrast in larger vessels, e.g. carotid artery. Requires the
Vascular/Abdominal Contrast option enabled.
• Abdominal Contrast imaging: optimized to visualize
contrast in abdominal organs, e.g. liver and kidneys.
Requires the Vascular/Abdominal Contrast option enabled.
Data acquisition
Left Ventricular Contrast Imaging
The Left Ventricular (LV) Contrast application has an optimized
system preset for Left ventricular opacification, optimal
resolution of endocardial borders delineationand for optimal
assessment of wall motion.
The LV Contrast application may help to identify LV thrombus
and evaluate wall motion.
WARNING
Abdominal and Vascular Contrast applications are for research
purposes only. Diagnosis must not be based on results achieved
by contrast analysis alone.
WARNING
Misdiagnosis based on image artifacts
Misdiagnosis in ultrasound contrast images may be caused by
several artifacts, most importantly:
Motion artifacts: gives rise to signals independently of contrast
presence. This may be caused by patient movement; including
respiration, or by probe movement influenced by the operator.
Regional drop outs: caused by unintentional destruction of the
contrast agent, too low concentration of contrast agent, poor
acoustic penetration due to rib/lung shadows or system failing to
detect the contrast agent due to erroneous settings induced by
the operator.
Tissue harmonics: gives contrast-like signals independently of
the presence of contrast agent.
