Value of Transvaginal Two-Dimensional Contrast-Enhanced Ultrasonography in Diagnosing Atypical Ovarian Corpus Luteum Hematoma
Table 2
Grading perfusion intensity by contrast-enhanced ultrasound.
Grade 1
Slight enhancement
Perfusion within the mass but significantly lower enhancement compared with surrounding tissues
Grade2
Moderate enhancement
Perfusion within the mass with similar enhancement compared with surrounding tissues
Grade 3
High enhancement
Perfusion within the mass and significantly higher enhancement compared with surrounding tissues, similar to or higher than the perfusion intensity of iliac vessels
