The testis is a richly vascularized organ supplied by low-flow thin caliber vessels that are only partially detected by traditional Doppler systems,
such as color and power Doppler.
:
However, in the vascular representation, these techniques determine, albeit to different extents, a cut of the weak vessels due to the necessary
application of wall filters that cut the disturbing frequencies responsible for artifacts generated by pulsations of the vascular walls and surrounding
tissues.
:
These filters cut a specific range of disturbing frequencies, regardless of whether they may be generated by low-flow vessels.
:
Recently, a new technology, called Ultrasound Microvascular Imaging (MicroV) has been developed, which is particularly sensitive to slow flows.
This new mode is based on new algorithms capable of better selecting the low frequencies according to the source of origin and cutting only the
disturbing ones, saving the frequencies originating from really weak flows.
:
When Ultrasound microvascular imaging is used, the vascular map is more detailed and composed of macro and microvasculature, with more
subdivision branches, facilitating the interpretation of the normal and, consequently, the pathological.
:
This review aims to describe the vascular architecture of the testis with Ultrasound Microvascular Imaging (MicroV) in healthy testis, compared to
traditional color/power Doppler, related to normal anatomy.
