Ultrasound revealed a 2 cm echogenic mass in the urinary bladder, avascular by both color and power Doppler [Figure 1]. With superb microvascular imaging (SMI), blood flow was clearly seen in the lesion [Figure 2 and Video 1] making the diagnosis of tumor more likely.
The same patient in Figure 1, superb microvascular imaging shows clearly the vessels in the mass (the white dots are the vessels).

SMI, however, demonstrated numerous blood vessels within the pannus [Figure 6 and Video 2] , consistent with active disease.

Transabdominal ultrasound performed by the gynecology team showed a 2.5 cm cyst of the right ovary with no flow in the ovary by color and power Doppler, findings suspicious for ovarian torsion [Figure 3a]. With using SMI, flow was easily depicted in the ovary, and torsion was ruled out [Figure 3b].

A 16-year-old previously healthy girl presented with right lower abdominal pain and vomiting of 10 h duration. (a) Power Doppler of ovary shows no flow and (b) using Doppler superb microvascular imaging the flow is clearly seen rolling out torsion of ovary.

A 17-year-old girl presented with right lower quadrant pain and vomiting which began the day before. (a) Power color failed to show flow in ovary mass that is adjacent to ovary mass and (b) superb microvascular imaging also failed to show flow that encouraged us to do the diagnosis of ovary torsion which was confirmed surgically.

The pannus was avascular according to color and power Doppler [Figure 5].
A 43-year-old man with rheumatoid arthritis presented with pain and swelling of the right knee. Power color show a pannus in the suprapatellar bursa without flow.

Ultrasound showed a 2.5 cm mass in the lower pole of the left kidney [Figure 7a]. With SMI, the mass lesion showed normal-cortical vasculature [Figure 7b], confirming the diagnosis of dromedary hump.
