Level of Evidence: Case Series
This study compares indocyanine green (ICG) angiography and multispectral reflectance imaging (MSRI) to determine tissue viability in breast reconstruction surgery patients.
The study found that ICG angiography overpredicted postoperative necrosis in comparison to MSRI. MSRI accurately predicted viability in almost all patients, while ICG angiography incorrectly predicted necrosis in many cases.
The study suggests that MSRI may be a better option for plastic surgeons in determining the likelihood of postoperative necrosis.

The article compares MSRI and ICG angiography for tissue perfusion assessment in breast reconstruction surgery. The authors suggest that angiography may overpredict tissue necrosis, while MSRI is a non-invasive method that can analyze tissue oxygenation without any tracer or dye.
