Multiparametric Ultrasound (mpUS) of a Rare Testicular Capillary Hemangioma

Table 1

Time intensity curve analysis using a ROI within the hemangioma and surrounding testicular tissue.

TIC parameter	Hemangioma	Testicular tissue
PI (1.0-5 AU)	45.6	3.4
TTP (s)	4.2	4.4
MTT (s)	7.0	10.1
Slope (1.0-5 AU/s)	13.0	1.0
Area (1.0-5 AU/s)	2007.9	130.0
AreaWI (1.0-5 AU·s)	121.3	9.7
AreaWO (1.0-5 AU·s)	1886.6	120.3

ROI within the capillary hemangioma demonstrated higher PI, shorter MTT, higher slope, and higher wash-in/wash-out rates compared to regular testicular tissue. Abbreviations: ROI: region of interest; PI: peak intensity; TTP: time to peak; MTT: mean transit time; AreaWI: area wash-in; AreaWO: area wash-out.
