[Diagnostic value of 2-dimentional ultrasonography and color Doppler flow imaging in primary bone tumor].
Zhong Nan da Xue Xue Bao. Yi Xue Ban = Journal of Central South University. Medical Sciences 2006 June
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).
CONCLUSION: 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.
