Postoperatively, surveillance of neck nodes allows for early detection of disease recurrence. Neck sonography, by virtue of its ease of use and ability to screen the neck for abnormal lymph nodes, is the primary imaging modality employed for screening, mapping, and surveying neck lymph nodes in ...
Presence of abnormal lymph nodes overrides US features of thyroid nodule(s) and should prompt US-guided FNA or biopsy of lymph node and/or ipsilateral nodule. EditLiver EditAnatomy Hover over image for legend Ligamentum teres → obliterated umbilical vein Ligamentum venosum → remnant of ductus ...

the doctor can visualize the esophagus, mediastinum, stomach, duodenum, pancreas, parts of liver and kidneys, gallbladder, spleen, left adrenal gland, and all surrounding lymph nodes. A “lower EUS” usually refers to a c...
Abnormal lymph nodes, calcifications, and visibility of posterior border were marked as present or absent. Using a system 0–48 based on similar characteristics, A. Hočevar and colleagues determined that a cut-off score of 17 resulted in a specificity of 98.7% and a sensitivity of 58.8% [...
Cancer: Ultrasound can be used to identify masses within the abdomen, enlarged lymph nodes, and other changes that may suggest the pet has cancer. Chronic vomiting and/or diarrhea: The gastrointestinal tract may be scanned to look for causes of vomiting and diarrhea. Urinary tract issues: The ...
Examine internal organs and tissues (eg the appendix, bladder, gallbladder, kidneys, liver, lymph nodes, ovaries, pancreas, testes and thyroid gland) to diagnose a condition — an ultrasound scan can determine whether an abnormal lump is a solid tumour or fluid-filled cyst and can also detect...
Patients with abnormal lymph nodes (LN) detected on grey-scale ultrasound were not included. Patients whose initial SLN core biopsy was benign were compared with those who had a malignant SLN core biopsy. Results 555 patients with invasive breast cancer had SLN successfully identified and core ...
After 31 months (range 14-49 months), a high-resolution AU was performed for 107 patients with a negative sentinel node during surgery and without axillary dissection, to visualize any abnormal lymph nodes in the axilla. If necessary, large core biopsies were undertaken to obtain histology of ...
The most common malignant cause of abnormal axillary lymph nodes is breast cancer (3). In addition, other primary tumors can cause axillary lymph node metastases (e.g., malignant melanoma, stomach, lung or ovarian carcinomas) (4). Invasive methods such as fine needle aspiration, biopsy or ex...
