Adjuvant Therapy for Intermediate Risk HER2 Positive, Lymph Node Negative Early Breast Cancer With Chemotherapy Combined Target Therapy
Human epidermal growth factor receptor 2 (HER2) positive breast cancer is a molecular subtype with high malignancy and easy recurrence and metastasis. The emergence of HER2 targeted drugs has greatly improved the prognosis and survival of such patients. At present, for HER2 positive breast cancer patients with negative lymph nodes, …
Research on Key Technology Development and Clinical Application of Small Interactive Spinal Endoscopic Surgery Robot
The aim of the study was to investigate the correlation between the extent of decompression and patient follow-up metrics at 1 year postoperatively by analysing data from a real-world, multicentre cohort of patients, and to clarify the precise extent of decompression for endoscopic spine surgery.
Deep Learning for Automated Discrimination Between Stage T1-T2 and T3 Renal Cell Carcinoma on Contrast-Enhanced CT
This study aims to develop and validate a contrast-enhanced CT-based deep-learning model for automatic and accurate preoperative discrimination between T1-T2 and T3 renal cell carcinoma. By quantifying the model's diagnostic performance on an independent test set-using AUC, sensitivity, specificity, positive/negative predictive values, and decision-curve analysis-we will establish a decision-support tool …
Automated Bone Age Estimation From Noncontrast Abdominal CT Using Deep Learning
This study is a retrospective analysis that uses abdominal CT scans, which were originally taken for other medical reasons, to estimate bone age. By applying advanced deep learning methods, we aim to develop a tool that can evaluate bone health and detect early signs of osteoporosis without requiring additional scans …
New Screening and Diagnostic Cut-off Points of PA Patients
This study aims to establish the screening and diagnostic cut-off points for primary aldosteronism patients by a novel small molecule "sandwich method" aldosterone and renin chemiluminescent immunoassay.
The Development and Validation of MRI-AI-based Predictive Models for CsPCa
This study retrospectively included patients who underwent prostate magnetic resonance imaging (MRI) and subsequent ultrasound-guided prostate biopsy at Peking University First Hospital from January 2019 to December 2023, and prospectively enrolls patients from January 2024 to December 2029. Clinical information such as age, PSA levels, PI-RADS scores, and digital rectal …
Chronic Airway Disease and Multimorbidity Cohort
Background: Chronic airway diseases (CAD), including chronic obstructive pulmonary disease (COPD), asthma and bronchiectasis, are highly prevalent and cause serious disease burden. Multimorbidity is recognized to influence treatment decision and prognosis of patients with stable CAD. The impact of multimorbidity on exacerbation CAD is under investigated. Methods: The Chronic Airway …
Chinese PE Multimodality Imaging Artificial Intelligence Study
The CHinese pulmOnary Embolism Multimodality Imaging-artifiCial intelligencE Study (CHOICE) is a prospective observational multi-center study that will collect imaging text data and raw data of patients with pulmonary embolism (PE) in China. By combining artificial intelligence technology, it aims to identify imaging markers to assist in early diagnosis, differential diagnosis, …
ICAS Screen Based on RIC
Intracranial atherosclerosis stenosis (ICAS) is a leading cause of ischemic stroke worldwide and increase the global burden of stroke, especially in the Asian population. Compared with the other stroke subtypes, patients with ICAS had more severe stroke, stayed longer in the hospital and higher risk of recurrent ischemic events. Thus, …
Application of QDSA Platform in Cerebrovascular Diseases
Cerebrovascular diseases pose a major global public health challenge, characterized by exceptionally high mortality and disability rates, with their pathogenesis closely linked to hemodynamic abnormalities. The quantitative digital subtraction angiography (QDSA) analysis platform, leveraging its advantages of vessel modeling-free operation, high computational efficiency, and DSA-equivalent sensitivity, has emerged as a …
