Microbubble contrast-enhanced uses contrast media of encapsulated inert structures, highly reflected by the apparatus that improve the color and spectral Doppler signal (9).
"We are especially excited to offer innovative technology such as the Thera-Clean MicroBubble baths--a special product/service specifically designed for dogs to help with shedding, hip dysplasia, senior dogs and allergy and skin issues," Senafe said.
Color Doppler ultrasound, tissue harmonic imaging, and the newly introduced microbubble contrast agents considerably contribute to the characterization of such lesions (2,4,6,7).
Computed tomography is less suitable for MI since its sensitivity is at the millimolar scale, which is significantly lower than MRI (micromolar range), US (single microbubble), or nuclear medicine (picomolar range).
The use of microbubble contrast agent as vascular tracer and enhancer allows the functional imaging of hepatic microvascular perfusion before morphological changes of tissues can be detected, which is advantageous compared to traditional ultrasound imaging (5-7).
