Abstract：Objective To analyze the application value of CT perfusion imaging combined with dynamic enhancement in the dif-ferential diagnosis of solitary pulmonary nodules ( SPN) . Methods 75 cases of SPN patients admitted to our hospital were randomly selected as the research objects and were given the same layer dynamic CT enhanced scanning. According to the results of the scan, time density curve (TDC) was established, and statistically analyzed. Results (1) Compared with inflammatory nodules and small cell lung carcinoma, tuberculoma BV, BF and PS were significantly lower (P<0. 05). (2) After the enhanced scanning, compared with tuberculoma, inflammatory nodules and small lung cancer CT values were significantly higher ( P<0. 05 ) . ( 3 ) After the en-hanced scanning, the tuberculosis group had flat manifestation, the inflammatory nodule group showed a rising trend, and the small lung cancer group was in a state of dynamic equilibrium. Conclusion CT perfusion imaging combined with dynamic enhanced scan can improve the diagnostic accuracy in the differential diagnosis of SPN.
