Diagnosis of intrathoracic masses by transesophageal color Doppler echocardiography.
OBJECTIVE
To evaluate the value of transesophageal color Doppler echocardiography in the diagnosis of intrathoracic masses.


METHODS
Twenty patients with intrathoracic masses were examined by transesophageal echocardiography (TEE), including 12 patients with central lung masses and 8 with mediastinal masses. The neoplasms were explored by two-dimensional realtime ultrasonography, Doppler color flow imaging (DCFI) and pulsed Doppler (PD). The results were compared with computed tomography (CT), operative and pathological examination findings.


RESULTS
We were able to identify the size, structure (solid or cystic), anatomic relationship, metastatic lymph nodes and venous carcinoembolus of the masses. Furthermore, the hemodynamic data in the vasculature inside the masses were detected.


CONCLUSIONS
As a new method, TEE with Doppler technique is not only valuable in differentiating malignant and benign neoplasms but also useful for preoperative evaluation of the mass resectability in patients with intrathoracic neoplasms.
