Abstract
We have noted a new characteristic colour Doppler (CD) appearance on liver ultrasound after giving the echo-enhancing agent Levovist (Schering Health Care). Levovist is an intravenous microbubble ultrasound contrast agent which improves a Doppler study by increasing the signal intensity from blood vessels by 10–25 dB; the duration of useful enhancement lasts 1-5 min.1,2 It is not regarded as producing parenchymal enhancement, but while doing Levovist ultrasound studies of the abdomen, we noted strong, transient, wide-frequency CD signals in the liver parenchyma, appearing on real-time colour Doppler scanning as flashes of polychromatic colour for several minutes after intravenous injection.
