- Original description
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 novel hemodynamic assessment method with significant clinical potential. This study aims to establish a cerebrovascular disease cohort incorporating QDSA parameters to systematically validate the clinical value of this technology in preoperative evaluation and surgical planning, thereby providing evidence-based insights for optimizing diagnostic and therapeutic strategies.Read full original descriptionShow less
Research on the Application of Quantitative Digital Subtraction Angiography Hemodynamic Analysis 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 novel hemodynamic assessment method with significant clinical potential. This study aims to establish a cerebrovascular disease cohort incorporating QDSA parameters to systematically validate the clinical value of this technology in preoperative evaluation and surgical planning, thereby providing evidence-based insights for optimizing diagnostic and therapeutic strategies.
Inclusion: Cerebrovascular diseases diagnosed and assessed by DSA for related risks and treatment options; The DSA acquisition protocol complies with the standard procedure; DSA images must include complete anteroposterior and lateral views; Raw data must be available in DICOM format; Image quality and pixel resolution must support data analysis; Patients must undergo regular follow-ups.
Exclusion: Cerebrovascular diseases not diagnosed or risk-assessed using DSA; Severe organ diseases with an expected survival period of less than 2 years; Other conditions deemed by the investigator as unsuitable for participation in this trial; Patients with DSA image quality insufficient for image analysis and processing; Inability to cooperate with treatment and follow-up; Participation in other clinical trials within the past 6 months.
