Inclusion criteria
Inclusion criteria: 1. The cases corresponding to the included cervical lymphatic images must be patients who underwent cervical lymphatic ultrasound imaging in Shanghai Sixth People's Hospital and Shanghai Dongfang Hospital after January 2017, and the ultrasound images of the largest section of cervical lymph at the time of examination were taken; 2. The cervical lymphatic ultrasound image is clear and complete, meets the requirements of ultrasound quality control, the resolution is not less than 480P, and it meets the common conditions of clinical diagnosis; 3. For patients without gender and age ratio requirements, ultrasound images of imaging examination are randomly selected; 4. Ultrasound images contain at least 1 lymph and no more than 3 lymphs; 5. Contain as much as possible normal lymph, abnormal lymph in different states of common conditions; 6.

Exclusion criteria
Exclusion criteria: 1. Cervical lymphatic ultrasound images of patients admitted to the hospital with a history of lymphoma or surgery; 2. In multiple lymphs, or lymphatic overlapping ultrasound images, none of the lymph is completely displayed; each lymph is occluded, unclear, or out of range of the image. In these cases, this ultrasound image should be excluded from the study data; 3. Ultrasound images that are not suitable for clinical research in the judgment of the investigator include but are not limited to the following: the lymphatic region of the ultrasound image is marked, which affects the observation and analysis; Investigator considers it inappropriate to participate in clinical studies due to patient considerations; with other pathologies, conditions that interfere with lymphatic analysis; 4.
