[Diagnostic value of 2-dimentional ultrasonography and color Doppler flow imaging in primary bone tumor].
OBJECTIVE
To explore the diagnostic value of 2-dimentional ultrasonography and color Doppler flow imaging (CDFI) in primary bone tumor.


METHODS
The hemodynamic parameters such as systolic maximum velocity (Vmax), diastolic minimum velocity (Vmin), resistance index (RI), and pulsatility index (PI) of intratumoral folw in 93 patients with primary bone tumors proved by histopathology were studied using 2-dimentional ultrasonography and CDFI techniques.


RESULTS
The bone destruction periosteum response and soft tissue mass were essentially revealed with 2-dimentional ultrasonography techniques. The intratumoral flow features were clearly shown by CDFI. The Vmax and Vmin in malignant bone tumor were significantly higher than those in benign one (P < 0.01). RI and PI in malignant bone tumor were lower than those in benign one (P < 0.01).


CONCLUSIONS
Observing the features of bone tumor and hemodynamic parameters by 2-dimentional ultrasonography and CDFI has a great clinical value in diagnosing primary bone tumor and distinguishing the malignant and benign bone tumors.
