Purpose To estimate and discuss the feasibility of the threshold value of the internal tumor volume (ITV) of lung cancer based on the standardized uptake value (SUV) of the background.Materials and Methods The phantom was designed with 3 vacuous models fixed at the bottom of a barrel. The 3 vacuous models were filled with18F-FDG (55.0 kBq/ml) which represented a tumor and the barrel was filled with18F-FDG (5.9 kBq/ml), which represented the background of the lung. The barrel moved sinusoidally with distances of 10.9 mm, 21.8 mm, and 43.7 mm to simulate breathing, and then the phantom 2D PET/CT data were acquired. The SUV in the background was recorded as ±SD, and+3SD was regarded as threshold value to obtain the measured ITVs. The Dice similarity coefficient (DSC) and volume recovery coefficient (VRC) were used to evaluate the accuracy of the ITVs measured by seven methods, including that by SUV 2.5, 35% SUVmax, 41% SUVmax, a×mSUV70+b×, 0.42×(SUVmax+) and Riegel et al. computed threshold value followed the gross tumor volume, tumor-to-nontumor ratio and motion extent.Results Nine ITVs of three lung cancer models were 134.3 ml, 166.1 ml, 223.5 ml, 86.6 ml, 108.5 ml, 150.7 ml, 32.3 ml, 43.8 ml and 63.6 ml, respectively. The ITV measured by Riegel et al. showed no difference with the real ITV (t=-0.48,P>0.05). The ITVs measured by the other six methods were significantly different from the real ITVs (t=-5.11-2.76,P<0.05). The DSC of the ITV measured by+3SD and the method of Riegel et al. were 0.75-0.92 and 0.69-0.93, respectively; and the VRC were 0.82-0.97 and 0.74-0.96, respectively (differences without significance:t=-0.73,P>0.05). Moreover, they surpassed the results of the other five methods.Conclusion The threshold value (+3SD) of the SUV determined by the background has potential value in the description of the ITV of lung cancer, so as to provide reference for radiotherapy.
