Objective To explore the impact of deep learning image reconstruction(DLIR)algorithms on image quality of chest CT,detection rate of lung nodule and reproducibility of lung nodule radiomics feature data compared with adaptive statistical iterative reconstruction V(ASIR-V)algorithms.Methods Seventy-five patients with 211 lung nodules who underwent both ultra-low-dose CT(ULD-CT)and standard-dose CT(SDCT)were prospectively enrolled.ULD-CT images were reconstructed using different algorithms,namely high-level DLIR(DLIR-H),medium-level DLIR(DLIR-M)and 50%ASIR-V(50%ASIR-V),while SDCT images were reconstructed by 50%ASIR-V.Image noise was represented by the standard deviation(SD)of lung parenchyma CT values within identical ROI in both ULD-CT and SDCT images,and signal-to-noise ratio(SNR)were calculated.The detection rate of lung nodule were obtained and compared among different images.Radiomics features of lung nodules in chest 50%ASIR-V SDCT and each ULD-CT were extracted based on automatic segmentation methods,and intra-class correlation coefficients(ICC)of each ULD-CT and 50%ASIR-V SDCT were calculated respectively,and then compared among different ULD-CT algorithms.Results Compared with SDCT images reconstructed with 50%ASIR-V algorithm,all ULD-CT images reconstructed by different algorithms showed higher SD and lower SNR(all P<0.05).ULD-CT images reconstructed by DLIR-H,DLIR-M and 50%ASIR-V exhibited progressively increasing SD and decreasing SNR(all adjusted P<0.05).Taken 50%ASIR-V SDCT images as standards,ULD-CT by DLIR-H,DLIR-M and 50%ASIR-V each detected 207 lung nodules(207/211,98.10%),respectively.In chest ULD-CT images,the reproducibility with 50%ASIR-V SDCT for texture feature data of lung nodules on ULD-CT reconstructed by 50%ASIR-V algorithm was lower than that by DLIR-H and DLIR-M(both adjusted P<0.05),while no significant difference was found between the latter two with 50%ASIR-V SDCT(adjusted P>0.05).The first order and shape feature data of lung nodules on ULD-CT reconstructed by all 3 algorithms showed good reproducibility with 50%ASIR-V SDCT(median ICC>0.75),and no significant difference was detected among them(all P>0.05).Conclusion Compared with 50%ASIR-V ULD-CT,both DLIR-H and DLIR-M ULD-CT could significantly reduce image noise and improve image quality,as well as maintain reproducibility of radiomics features in lung nodules in a certain degree,especially DLIR-H.

Objective:To compare the efficacy of hepatic artery infusion chemotherapy (HAIC) combined with targeted therapy and immunnotherapy and transarterial chemoembolization (TACE) combined with targeted therapy and immunnotherapy in the treatment of unresectable hepatocellular carcinoma HCC.Methods:We retrospectively analyzed the clinical data of 40 patients with unresectable HCC treated with HAIC combined with targeted therapy and immunnotherapy and TACE combined with targeted therapy and immunnotherapy in Tongde Hospital of Zhejiang Province and Zhejiang Provincial People's Hospital.The patients were divided into HAIC group ( n=14) and TACE group ( n=26) according to the different treatment methods. Baseline data, surgical conversion and intraoperative situation, tumor response, portal vein cancer thrombus control rate, leukocyte reduction rate, platelet reduction rate, incidence of liver function abnormalities, objective remission rate, and disease control rate were compared between the two groups. Results:The HAIC group had a later baseline tumor staging than the TACE group (higher percentage of portal vein cancer thrombus, CNLC stage Ⅲa).The surgical conversion rate of the HAIC and TACE groups were 28.6%(4/14) and 26.9%(7/26), respectively, with the difference of no statistical significance ( P>0.05);The operation time and intraoperative bleeding were (329.5±19.9) min vs.(413.4±26.4) min, (272.2±49.9) ml vs.(536.0±123.6) ml, and the differences were statistically significant ( P<0. 05); The maximum tumor diameter reduction rate [(30.7%±15.1%) vs.(7.2%±12.6%)] and portal vein cancer thrombus control rate [100% (12/12) vs. 64.3% (9/14)], the differences were statistically significant ( P<0.05);The incidences of leukocyte and platelet decrease in the two groups during the course of treatment were 71.4%(10/14) vs. 34.6%(9/26)、78.5%(11/14) vs. 38.5%(10/26), and the incidences of liver function abnormalities were 35.7%(5/14) vs. 69.2%(18/26), the differences were statistically significant ( P<0.05);The objective response rate and disease control rate were 57.1%(8/14) vs. 30.8% (8/26)、71.4% (10/14) vs. 53.8%(14/26), all statistically significant. Conclusion:HAIC combined with targeted therapy and immunnotherapy is a safe and effective treatment for middle and advanced HCC, especially suitable for patients with portal vein tumor thrombus(PVTT), large tumor, or poor liver function.
