Abstract		Purpose: The aim of this study was to determine the volume and vascularisation of tumours by three-dimensional (3D) power Doppler ultrasound in patients with "tumours of the oral cavity". Materials and Methods: Three-dimensional (3D) power Doppler ultrasound investigation was performed pre-operatively on 49 patients with carcinomas of the oral cavity. Digitally-stored data were analysed with 3D View program software, a part of which is the "VOCAL-Imaging program". By using VOCAL, the borders of a structure (tumour) can be determined and its volume calculated. The vascularisation of the tumour was determined by analysing three-dimensional colour histograms, and the vascularisation indices were calculated. Results: Vascularisation indices VI and VFI were significantly higher in patients with neck metastases. The differences between the vascularisation indices in N+ and N0 necks were statistically significant (p < 0.05). The flow index (FI) values between N+ and N0 necks were not statistically different. Conclusion: The volume and vascularisation of tumours of the oral cavity could be determined effectively by three-dimensional power Doppler ultrasound. Tumour vascularisation is higher in metastatic than in non-metastatic tumours.
