this is used to know the pathology & anatomy

contrast media

indication of contrast media is to:?

-identify the anatomy and pathology process in the blood vessels
-to evaluate claudication
-to look for vascular stenosis or occlusion (blockage/hollow organ)
-to detect and verify the existence & exact position an intracranial vascular lesion (brain)

what are the co-indications:?

-creatinine/ BUN
-blood pressure (hypertensive/hypotensive)
-pregnant
-patient refusal
-undergoing other procedures (e.g. kemotherapy)

an agent used before as a contrast media

chalk

who produced the first radiograph of the blood vessels of an amputated hand?

Haschek & Linderthal

when was the first radiograph of the blood vessels of an amputated hand produced?

January 1896

what year did researchers used sodium iodide as contrast media in lower limb?

1920

what year when contrast medium injected through a needle that punctured the vessel/ through a catheter inserted through a peripherally exposed vessel

1950s

when was the development of a flexible thin-walled catheter was made?

1952

what is called to the development of a flexible thin-walled catheter

Seldinger technique

refers to the developement of casette changes, roll film changer, cut film changer and line & serial spot filming/ digital devices

serial imaging

refer to as organic iodide solutions

contrast media

what is the effect of a contrast media

-peripheral vasodilation -decreased blood pressure -cardio toxicity -may also produce nausea and an uncomfortable burning sensation -may involve an allergic reaction

an effect in contrast media that has a slightly difficulty in breathing

minor

an effect of contrast media that has effect of shock and loss of conciousness

severe

what is the typical amount of iodine concentrations used in cerebral and limb angiography?

30%

it distribute oxygenated blood i the body

arteries

concentration for visceral angiography

35%

concentration of lower of peripheral renography

30%

agents that has higher concentration

iodine agents

agents that are more viscous and produce greater resistance in the catheter during injection

non-ionic agents

it is less radiopaque than blood and appears as a negative or void in angiographic imaging

CO2

presence of air or gas in the abdominal (peritoneal cavity)

pneumoperitoneum

may be used as an alternative contrast media

gadolinium

the primary contrast agent in MRI

gadolinium

contrast media that is less radiopaque than iodine

gadolinium

narrow window are used

digital subtraction angiography
