Abstract: | We studied the role of colour Doppler energy (CDE) (or power Doppler)
imaging in the differentiation between endometriomas and other adnexal
masses in premenopausal non-pregnant women. A total of 170 consecutive
patients with persistent adnexal masses was submitted to B-mode
transvaginal ultrasonography associated with CDE imaging evaluation. Plasma
concentrations of CA125 were measured before surgery. Using CDE imaging
evaluation of vessel distribution, the occurrence of one of the following
findings was considered to indicate the likely presence of endometrioma:
(i) a round-shaped homogeneous hypoechoic 'tissue' of low- level echoes
without papillary proliferations associated with 'poor' vascularization;
(ii) a round-shaped homogeneous hypoechoic 'tissue' of low-level echoes
with an echogenic portion in which no flow was detected. The overall
agreement between the test result and the actual outcome was calculated
using the k index. The CDE imaging evaluation was more accurate in the
diagnosis of endometriomas compared with B- mode ultrasonography alone (k =
0.88 and 0.80 respectively). According to the logistic regression equation
obtained, the probability of the presence of endometrioma varied between a
minimum of 1.4% for patients with no risk factors to a maximum of 95.6% for
patients with two risk factors (CDE result and value of CA125 >25
IU/ml).
