Among the common groups of ophthalmologic disease, fluorescein angiography can detect diabetic retinopathy (neovascularization), vein occlusions, retinal artery occlusions, [4] edema of the optic disc, and tumors. Additionally, the transit time (the period between injection of the dye and when it appears in the examined blood vessels) can ...
Fluoroscopy is also used in airport security scanners to check for hidden weapons or bombs. These machines use lower doses of radiation than medical fluoroscopy. [ 12 ] The reason for higher doses in medical applications is that they are more demanding about tissue contrast, and for the same reason they sometimes require contrast media .
Intravenous or oral fluorescein is used in fluorescein angiography in research and to diagnose and categorize vascular disorders including retinal disease, macular degeneration, diabetic retinopathy, inflammatory intraocular conditions, and intraocular tumors. It is also being used increasingly during surgery for brain and spine tumors. [24]
Digital subtraction angiography (DSA) is a fluoroscopy technique used in interventional radiology to clearly visualize blood vessels in a bony or dense soft tissue environment. Images are produced using contrast medium by subtracting a "pre-contrast image" or mask from subsequent images, once the contrast medium has been introduced into a ...
Sulfonylureas, a class of type 2 diabetes medications, are associated with higher risk of impaired awareness of hypoglycemia when used over the long term in a new study.
Two forms of radiographic images are in use in medical imaging. Projection radiography and fluoroscopy, with the latter being useful for catheter guidance. These 2D techniques are still in wide use despite the advance of 3D tomography due to the low cost, high resolution, and depending on the application, lower radiation dosages with 2D technique.
French fries are particularly bad for diabetics as the combination of carbs in the potatoes and trans fats in the oil will cause a huge spike in blood sugar.
The catheter of choice to cannulate this area is pigtail catheter with multiple side holes. Contrast injection rate of 20 to 25ml/sec is given with total volume of 40 to 50 ml of contrast. The frame rate of fluoroscopy is 4 to 6 frames per second. [8] The image is taken in with the x-ray tube in left anterior oblique position. [8]
