The impact of molecular classification based on the transcriptome of pancreatic cancer: from bench to bedside
Chinese Journal of Academic Radiology - Tập 3 - Trang 67-75 - 2020
Yan Deng, Ting Zhou, Jia-long Wu, Yong Chen, Cheng-yi Shen, Mei Zeng, Tianwu Chen, Xiao-Ming Zhang
Pancreatic cancer is a malignancy with a 5-year overall survival rate of less than 10% and is the third leading cause of death among cancers. Total resection is the only potentially curative treatment. Unfortunately, less than 20% of patients are candidates for surgery. High-throughput molecular analysis has revealed the intra- and inter-heterogeneity of pancreatic cancer, leading to a challenge f... hiện toàn bộ
An artificial intelligence-assisted framework for fast and automatic radiofrequency ablation planning of liver tumors in CT images
Chinese Journal of Academic Radiology - - 2024
Ruikun Li, Rui Xin, Shuxin Wang, Guisheng Wang, Lifeng Zhao, Huijie Jiang, Lisheng Wang
To develop and validate an artificial intelligence (AI)-assisted framework for fast and automatic radiofrequency ablation (RFA) planning of liver tumors from CT images. This framework consisted of three steps. First, the abdominal multi-organs related to RFA planning were automatically segmented from CT images using a modified nnU-Net with class-weighted loss function. Then, utilizing the segmente... hiện toàn bộ
Correction to: Evaluation of collateral circulation based on a single time-variant color map of multi-phase CTA and its association with CTP parameters
Chinese Journal of Academic Radiology - - 2021

A confirmatory study of the calibration formula between liver iron concentration (LIC) and R2* values in thalassemia patients
Chinese Journal of Academic Radiology - Tập 6 - Trang 65-72 - 2023
Fengming Xu, Jixing Yi, Cheng Tang, Chaotian Luo, Peng Peng
To explore the maximum LIC range applicable to LIC-R2* calibration formula of different studies. The liver T2* images of 195 thalassemia patients were measured by CMRtools/Thalassemia Tools (CMRtools), and the calculated T2* values were converted into R2* values. The R2* data were calculated according to the calibration formula of different studies to calculate the corresponding liver iron concent... hiện toàn bộ
Pulmonary contusions and lacerations: CT findings that every radiologist must know
Chinese Journal of Academic Radiology - - Trang 1-7 - 2024
Camilo Dallagnol, Juan M. F. Alcala, Rafaelle M. Vargas, Gustavo R. dos Santos, Dante L. Escuissato
Pulmonary contusions and lacerations are the main types of pulmonary parenchymal traumatic lesions. They are responsible for significant morbidity, and mortality. It may be challenging to differentiate them from other causes of pulmonary abnormalities in trauma patients, even using chest radiography. Nevertheless, there are specific computerized tomography findings that allow the better characteri... hiện toàn bộ
A multiparameter MRI-radiomics and clinical nomogram to predict the positive circumferential resection margin of rectal carcinoma
Chinese Journal of Academic Radiology - Tập 6 - Trang 73-81 - 2023
Yanqing Ma, Zheng Guan, Lifeng Qiu, Kaili Shang, Yuguo Wei, Yuan Hang
To construct a predictive nomogram combining multi-parameter MRI-based radiomics and clinical information to evaluate the circumferential resection margin (CRM) of rectal carcinoma (RC). This single-center study retrospectively recruited 301 RC patients including 66 patients with positive CRM status (CRM +) and 235 patients with negative CRM status (CRM−). Patients were randomly divided into train... hiện toàn bộ
Expert consensus on the colorectal cancer annotation of CT and MRI (2020) (translation)
Chinese Journal of Academic Radiology - Tập 4 - Trang 141-149 - 2021
Zhengyu Jin
Colorectal cancer is one of the most common clinical malignancies. The application of artificial intelligence to colorectal cancer can help to detect and diagnose lesions, evaluate curative effects and prognosis, and conduct follow-up, so as to benefit patients. To standardize the marking of colorectal cancer data and promote the better implementation of artificial intelligence in clinical practic... hiện toàn bộ
High signal liver focal lesions on DWI: the differential diagnostic value of morphological characteristics and ADC value
Chinese Journal of Academic Radiology - Tập 4 - Trang 48-55 - 2021
Hongtao Zhang, Fugeng Sheng, Jingjing Pan, Xiaojing Zhang, Wei Xu, Haiyi Wang, Huiyi Ye
To explore the value of DWI morphological characteristics and ADC value in differentiating malignant and benign lesions of the liver at 3.0 T. In this study, 310 patients with the same number of liver lesions confirmed by histopathology with high signal on DWI were collected. For each lesion, two radiologists independently measured the ADC values and evaluated the DWI morphological characteristics... hiện toàn bộ
Imaging features of renal lipid-poor angiomyolipomas: a pictorial review
Chinese Journal of Academic Radiology - Tập 5 - Trang 82-98 - 2022
Ze-Liang Liu, Yan Tan
Renal lipid-poor angiomyolipomas (lipid-poor AMLs) are usually difficult to differentiate from clear-cell renal cell carcinomas (RCCs), papillary RCCs, epithelioid AMLs, and oncocytomas, while the differentiation is important due to different treatments and prognoses. This pictorial review presents clinical, histopathological, and imaging (ultrasound [US], CT, and MRI) features of lipid-poor AMLs ... hiện toàn bộ
Quantitative MRI of liver grafts for assessment of macrovesicular steatosis ex vivo and long-term follow-up outcomes
Chinese Journal of Academic Radiology - - 2023
Gen Chen, Jianzhong Jiang, Xinqiang Wang, Hui Guo, Lifen Zhou, Daoyu Hu, Ihab R. Kamel, Zhishui Chen, Zhen Li
