Multispectral imaging: Review of current applications.

Area of Science:

• Ophthalmology
• Medical Imaging
• Retinal Imaging

Background:

• Multispectral imaging (MSI) is a layer-by-layer technique for visualizing retinal and choroidal pathologies.
• It detects reflectance signals from normal and diseased chorioretinal tissues.

Purpose of the Study:

• To summarize the imaging principles and current applications of MSI.
• To review recent technological advancements in the field.

Main Methods:

• MSI detects reflectance signals, differentiating between hyper- and hyporeflectance.
• Analysis of pigment absorption (hemoglobin, melanin) and interface reflections.

Main Results:

• MSI visualizes various pathologies, including retinovascular disorders, RPE changes, and choroidal lesions.
• New techniques create retinal and choroidal oxy-deoxy maps.

Conclusions:

• MSI provides insights into blood oxygen saturation and reflectance phenomena.
• Advances enhance the interpretation of MSI images for diagnosing ocular conditions.
