Official title
A Preliminary Study of Photoacoustic Imaging to Detect Micrometastases in the Lymph Nodes of Breast Cancer Patients
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
In this spectroscopic photoacoustic imaging study, the investigators will acquire images (only) to: 1. determine if spectroscopic photoacoustic imaging can acquire high fidelity images in a clinical setting, 2. discover if blood oxygen saturation changes are observable in breast cancer patients during early stages of metastatic invasion, and 3. compare the sensitivity and specificity of photoacoustic imaging with ultrasound imaging for the detection of lymph node metastases. The results from imaging will not be used in any decision making process. This study is solely used to test the photoacoustic imaging device and evaluate it against the current standard of care. The device is completely noninvasive and uses only safe levels of energy as determined by the American National Standards Institute (ANSI) and the FDA. The device does not pose a serious to the health, safety, or welfare of the patient.
