Gross tumour volume comparison in oropharynx carcinomas using different intelligent imaging software. A retrospective analysis.

Purpose: To compare gross tumour volume (GTV) in oropharynx carcinomas using different intelligent imaging software and to evaluate which method is more reliable for tumour volume definition in comparison with 3D ProSoma software.

Material And Methods: We retrospectively studied 32 patients with histopathologically confirmed oropharynx carcinomas on dual-source computed tomography (CT) (all patients underwent multislice CT examination after applying 75 ml iodinated non-ionic contrast media). One radiologist calculated the tumour volume - manually measuring tumour length (L), width (W), and height (H) - and then calculated the tumour volume using the formula 0.
