Enhanced color flows in XXXX .

@entity157 @entity99 @entity4383 @entity2695
BACKGROUND/AIMS: The study was to utilize both color Doppler sonography and power Doppler sonography to analyze the enhancement characteristics of @entity99 known to have a clinical or histologically confirmed diagnosis of @entity157 , @entity2695 , or @entity4383 . METHODOLOGY: Twenty-two @entity157 , 6 @entity2695 , and 2 @entity4383 were observed with color Doppler sonography and power Doppler sonography before and after contrast agent (Levovist) administration. Color Doppler sonography and power Doppler sonography were used to detect the intratumoral vasculature and their sensitivity would be evaluated. RESULTS: Significant improvement in the detection of color flow signals was obtained in @entity157 after administering Levovist (32% (7/22) vs. 91% (20/22); p = 0.0002), but it was not significant in @entity2695 (0% (0/6) vs. 33% (2/6); p = 0.454). Power Doppler sonography was more sensitive than color Doppler sonography in the detection of flow signals in @entity157 after administering Levovist (91% (20/22) vs. 50% (11/22); p = 0.008). Eighty percent (16/20) of @entity157 had signals of curvilinear type versus spotty type (p = 0.0005), the detected signal in both @entity2695 was iris diaphragm phenomenon. The typical spoke-wheel appearance of @entity4383 was more easily demonstrated after administering Levovist. The @entity157 with absent baseline flow (1.2-5.6 cm, mean: 3.1 +/- 1.0 cm) tended to be @entity157 with baseline flows (2.3-8.3 cm, mean: 4.9 +/- 2.2 cm) (p = 0.06). The 9 @entity157 (largest diameter: 1.2-3.8 cm, mean: 2.6 +/- 0.8 cm) with enhanced flows only observed by power Doppler sonography was smaller than the 11 @entity157 (largest diameter: 2.3-8.3 cm, mean: 4.5 +/- 1.8 cm) with enhanced flows observed by color Doppler sonography and power Doppler sonography (p = 0.01). CONCLUSIONS: Enhanced color flow study may aid in the detection of flow signals or sonographic differentiation of @entity99 .
