BASICS OF CONTRAST Flashcards
(33 cards)
WHAT IS THE ATOMIC NUMBER OR BARIUM
BARIUM 56
POSITIVE CONTRAST MEDIA APPEARS
WHITE / RADIOPAQUE
EXAMPLES OF POSITIVE CONTRAST MEDIA
BaS04 AND IODINATED CM
NEGATIVE CONTRAST MEDIA APPEARS
RADIOLUCENT OR BLACK
EXAMPLES OF NEGATIVE CONTRAST MEDIA
AIR, O2 AND CO2 GAS
MOST COMMON CM USED FOR THE VISUALIZATION OF GI TRACT
BARIUM SULFATE
PRIMARY MAIN SOURCE OF BARIUM
BARITE OR BARYTE
ADDITIVES USED IN BARIUM
GUM OF ACACIA
2 TYPES OF BARIUM PREPARATION
- COLLOIDAL PREPARATION
- SUSPENDED OR FLOCCULATION RESISTANT PREPARATION
DISPERSING AGENT THAT PREVENTS FLOCCULATION
SODIM CARBONATE OR SODIUM CITRATE
CHEMICALS THAT PREVENTS FOAMING OF CM
SIMETHICONE AND POLYSORBATE
CONTRAINDICATIONS OF BARIUM SULFATE
Ethel BOOBA
2 TYPES OF BaS04
- PLAIN BaS04
- COMMERCIAL BaS04
ATOMIC NUMBER OF IODINE
IODINE 53
CM THAT IS USED PRIMARILY FOR ANGIOGRAPHY, BILIARY, UROGRAPHIC PROCEDURES
IODINATED WATER SOLUBLE CM
IT ALSO USED IN GIT WHEN BaS04 is contraindicated
IODINATED WATER SOLUBLE CM
A TYPE OF IODINATED WATER SOLUBLE CM THAT HAS A HIGHER OSMOLALITY AND HAS A GREATER CHANCE OF REACTION
IONIC CM
CONTAINED IN IONIC CM, IT INCREASES THE SOLUBILITY OF THE CONTRAST MEDIA
CATION ( SODIUM AND MEGLUMINE)
HOW MUCH OSMOLALITY DOES IONIC CM HAS COMPARED TO BLOOD PLASMA
6 TO 8 TIMES HIGHER
CONTAINED IN IONIC CM, IT STABILIZES THE CONTRAST MEDIA COMPOUND
ANION (DIATRIZOATE, IOTHALAMATE, IOXAGLATE AND METRIZOATE) midi-ate
BLOOD PLASMA OSMOLALITY
290-295 MILLIOSMOLES/KG
TYPE OF IODINATED WATER SOLUBLE CM THAT HAS LOWER OSMOLALITY AND HAS LESSER CHANCE OF REACTION AND HAS LOWER OSMOLALITY
NON-IONIC CM
HOW MUCH OSMOLARITY DOES NON IONIC CM HAS COMPARED TO BLOOD PLASMA
2-3 TIMES HIGHER OSMALIRITY THAN BLOOD PLASMA
TYPE OF CONTRAST THAT HAS AN EQUAL OSMOLALITY TO BLOOD PLASMA
ISO OSMOLAR CONTRAST MEDIA
