Computed Tomography01:10

Computed Tomography

9.2K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Imaging Biological Samples with Optical Microscopy

11.9K
Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.
In optical microscopy, the specimen to be viewed is placed on a glass slide and clipped on the stage...

    Summary
    This summary is machine-generated.

    Optical coherence tomography (OCT) remains vital for evaluating diabetic retinopathy, aiding in the diagnosis and management of diabetic macular edema and other related retinal changes. OCT provides detailed insights into both non-proliferative and proliferative retinopathies, supporting comprehensive patient care.

    Area of Science:

    • Ophthalmology
    • Medical Imaging
    • Diabetology

    Background:

    • Diabetic retinopathy (DR) affects the posterior segment of the eye.
    • Optical coherence tomography (OCT) has been used for nearly 25 years in evaluating DR.
    • OCT is crucial for assessing pathological changes induced by diabetes.

    Purpose of the Study:

    • To provide an extensive overview of posterior segment pathological changes in diabetic retinopathy characterized using OCT.
    • To highlight the role of OCT in diagnosing, characterizing, and following up on diabetic macular edema (DME).
    • To detail the utility of OCT in identifying various lesions in non-proliferative and proliferative diabetic retinopathy.

    Main Methods:

    • Review of existing literature and clinical applications of OCT in diabetic retinopathy.
    • Qualitative assessment of retinal changes using OCT (e.g., DME pattern, cysts, fluid, layer integrity).
    • Quantitative assessment of retinal changes using OCT (e.g., macula volume, retinal thickness).

    Main Results:

    • OCT is essential for qualitative and quantitative assessment of diabetic macular edema (DME).
    • OCT aids in investigating structural changes associated with diabetic macular ischemia.
    • OCT identifies numerous lesions in non-proliferative (e.g., hyperreflective spots, microaneurysms) and proliferative (e.g., neovascularization, retinal detachment) diabetic retinopathy.

    Conclusions:

    • OCT is indispensable for the diagnosis, characterization, and follow-up of DME.
    • OCT provides valuable information on various ocular structures, including the vitreo-retinal interface, retinal layers, and choroid.
    • OCT significantly contributes to the comprehensive evaluation of diabetic retinopathy and its complications.
