Superb microvascular imaging (SMI) is a relatively recently developed ultrasound diagnostic technology that aims to visualize blood flow in blood vessels at low velocity and small diameter. Unlike conventional Color/ Power Doppler imaging, SMI can suppress the noise caused by motion artifacts without removing the weak signal from small blood flow, thus achieving higher sensitivity than duplex scanning. A clinical case of a 33-year-old woman who has been unsuccessfully treated for 6 months for non-lactational mastitis caused by a small-sized mixed fibroadenoma that compresses and involves the gland duct is presented. Repeatedly performed ultrasound in B-mode + duplex scanning made it possible to diagnose dilation of the duct with its inhomogeneous contents, however, due to the resolving capabilities of the ultrasound scanner, it didn’t allow visualizing the tumor. And only the use of SMI technology made it possible to intraductally localize the area of hypervascularization from microvessels, suspicious of neoplastic blood flow, which was later confirmed intraoperatively and morphologically verified as a tumor. |
