We investigated the correlation between color Doppler flow imaging (CDFI) and ultrasound (US)-guided diffuse optical tomography (DOT) for detection of breast tumor angiogenesis. Both CDFI and DOT were performed in 214 breast lesions scheduled for biopsy. The lesions were classified as vascular or nonvascular on CDFI and total hemoglobin concentration (THC) was measured by DOT. Sonographic results were correlated with the THC measurements. Pathologic examination showed 118 breast cancers and 96 benign breast masses. When vascularization on CDFI as a sign of malignancy and a cutoff of 140 μmol/L was used, the sensitivity, specificity and accuracy were 83.9, 50.0 and 68.7% for CDFI and 83.9, 66.7 and 76.2% for DOT, respectively. Thirteen (11.0%) nonvascular breast cancers presented high THC levels. Twenty-five (52.1%) vascular benign tumors demonstrated low THC levels. Mean THC did not differ significantly in malignancies with vascular or without vascular (228.14 ± 85.37 μmol/L vs. 191.42 ± 92.59 μmol/L; p > 0.05). Likewise, for benign lesions, the difference between THC values in vascular lesions and nonvascular lesions was not statistically significant (140.86 ± 79.63 μmol/L vs. 110.13 ± 85.05 μmol/L; p > 0.05). Our results suggest that the addition of DOT to CDFI could be helpful for characterizing CDFI nonvascular lesions that are suspicious for malignancy or vascular lesions that are probably benign.
