2. Specificity: the specificity of a diagnostic method refers to the ability to distinguish between tumor and other non-tumor lesions. High specificity means that the diagnostic method can accurately exclude non-tumor lesions and avoid misdiagnosis.
3. Accuracy: the accuracy of diagnostic methods refers to the ability to accurately determine the tumor type, staging and localization. High accuracy means that the diagnostic methods can provide accurate pathologic information, which is very important for the development of appropriate treatment plans and prognostic assessment.
4. Feasibility: The feasibility of a diagnostic method refers to whether the method is easy, fast and economical to implement, and whether it can be widely used in clinical practice. High feasibility means that the diagnostic method has good operability and universality.
