Identifying Ultrasonic Diagnostic Characteristics of Cervical Lymphadenopathy: A Retrospective, Multicenter Study
Identifying Ultrasonic Diagnostic Characteristics of Cervical Lymphadenopathy: A Retrospective, Multicenter Study
The observed indexes of the four cervical lymph node diseases were identified by informatics
 methods, and the differences in the diagnosis of the four diseases were evaluated, so as to
 improve the clinical diagnosis rate and provide a research basis for the ultrasonic
 evaluation of the surgical indications of cervical lymph node diseases in the future.
Inclusion Criteria:

 -  Patients with one of these four diseases

 Exclusion Criteria:

 -  1. Patients with severe heart and brain diseases and poor coagulation function. 2.
 Undiagnosed patients are not included in the statistical analysis. 3. Image distortion
 of CEUS acquisition cannot be analyzed.
