Abstract

The most common age group for PLC was 60–70 years, with males accounting for 69.4%.
In the groups of completely or partially solid, cavitary tumors, the mean Delta HU in the BAP  was significantly higher than in the PAP (34.26 ± 17.6 vs. 23.03 ± 19.6; 58.73 ± 16.0 vs. 45.91 ± 28.3; 45.91 ± 28.3 vs. 34.00 ± 15.4; P < 0.1).The degree of contrast enhancement was correlated with tissue density, being greater in the BAP than in the PAP. The difference between histopathological types and enhancement degree was not statistically significant (p = 0.522). The study showed that in both BAP and PAP, the strongly enhancing tumors had higher post-contrast HU values than the weakly enhancing ones (arterial phase: 83.23 ± 26.4 vs. 51.08 ± 9.4 HU; venous phase: 93.00 ± 23.5 vs. 66.15 ± 13.5 HU; p < 0.001). Among them, the BAP demonstrated a more pronounced and prolonged enhancement, with higher Delta HU compared to the PAP.
