Computer-aided ultrasonographic diagnosis of left atrium/left atrial appendage thrombus

Abstract

The invention discloses a computer-aided ultrasonic diagnosis method for left atrium / left atrial appendage thrombus. The technical scheme is: combining data mining technology and pattern recognition theory with medical clinical information, taking gray-scale video and real-time three-dimensional dynamic video as research objects , Accurately obtain all-round information in the image and mine potential disease association rules in the image information, comprehensively analyze multiple types of features, and obtain a detection method for automatic detection and classification of left atrial / left atrial appendage thrombus. The thrombus identification method disclosed in the present invention can avoid missed and misdiagnosed cases caused by subjective reasons such as insufficient experience of doctors or visual fatigue, and enable patients suspected of having left atrium / left atrial appendage thrombus to be diagnosed as early as possible through esophageal ultrasound detection, and the cause of thrombus formation can be ruled out. Patients can receive cardioversion therapy for atrial fibrillation as soon as possible. This method is simple and practical, and has important guiding significance for the diagnosis and treatment of left atrium / left atrial appendage thrombus and atrial fibrillation.

Description

technical field [0001] The invention relates to the technical field of computer-aided diagnosis, in particular to a method for computer-aided ultrasonic diagnosis of left atrium / left atrial appendage thrombus. Background technique [0002] Computer-aided diagnosis technology is referred to as CAD technology (Computer-Aided Diagnosis Technology). Computer-aided diagnosis includes at least two meanings: helping to find lesions and diagnosing lesions. The main advantage of computer-aided diagnosis of medical images lies in fast data processing and accurate quantitative calculation, which can provide clinical auxiliary diagnosis opinions with good consistency, high repeatability, objective and accurate, and reduce problems caused by doctors’ lack of experience or visual fatigue. Misdiagnosis caused by subjective reasons greatly expands the limited personal knowledge and experience of doctors, making the diagnosis more accurate and scientific. Therefore, although CAD is still i...

Problems solved by technology

At present, transesophageal ultrasonography is used clinically. During this process, patients with atrial fibrillation will have obvious spontaneous development, which makes it difficult to distinguish the images of left atrial appendage thrombus and comb muscle. Therefore, suspected left atrium / left atrial appendage thrombus All patients were treated with warfarin (an anticoagulant) for four weeks, and then repeated transesophageal ultrasound to test the authenticity of suspected left atrial / LAA thrombus

On the one hand, this method makes patients who may not have thrombus receive unnecessary anticoagulant therapy, which increases the risk of bleeding (especially for elderly patients); on the other hand, for patients with thrombus, the existence of thrombus cannot be ruled out in time. Persistent atrial fibrillation worsens cardiac structure and function in patients with fibrillation
