Official title
The Role of Ultrasound-Guided Photoacoustic Imaging in Detection of Metastases in Inguinal Lymph Nodes
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This early phase I trial studies how well ultrasound-guided photoacoustic imaging works in telling the difference between healthy and cancerous inguinal (groin) lymph nodes and how well it can detect certain features of lymph nodes, including size and shape in patients with cancer. Ultrasound-guided photoacoustic is a non-invasive imaging method that can detect and display characteristics of lymph nodes based on the level of oxygen in the cells. This imaging method may provide more accurate tumor staging and prevent unnecessary surgical interventions.
