METHOD FOR THE X-RAY VISULIZATION OF BODY CAVITIES WHICH COMPRISES ADMINISTERING TO THE BODY OF THE TEST OBJECT A PREPARATION WHICH CONTAINS A MEMBER SELECTED FROM THE GROUP OF POLYMERS BEING BUILT UP OF ALTERNATING 2,4,6-TRIIODOBENZOIC ACID DERIVATIVE GROUPS AND INTERMEDIATE ALIPHATIC HYDROXYL GROUP-CONTAINING BRIDGES, AND PHYSIOLOGICAL ACCEPTABLE SALTS THEREOF, AND THE PREPARATIONS SUITABLE FOR CARRYING OUT THE METHOD.
摘要:
A barium sulfate contrast medium which comprises a barium sulfate aqueous suspension having a barium sulfate concentration of 750 to 1,200 grams per liter of the suspension and containing carbon dioxide in combination with a suspending agent, said carbon dioxide being contained in the range of 0.2 to 4 gas volume.
WHEREIN Z AND Z'' ARE EACH EITHER AMINO GROUPS OF THE FORMULA
-NR1R2
WHEREIN R1 AND R2 ARE EACH HYDROGEN OR A LOWER ALKYL HAVING NO MORE THAN 5 CARBON ATOMS; OR Z AND Z'' ARE EACH AMINO GROUPS OF THE FORMULA
-N WHEREIN R1 AND R2 ARE LINKED TOGETHER INTO A HETEROCYCLIC RING SYSTEM; AND R3 AND R''3 ARE EACH A LOWER ACYL HAVING NO MORE THAN 5 CARBON ATOMS; AND WHEREIN A IS AN ALKYLENE GROUP SUBSTITUTED BY AT LEAST ONE SUBSTITUENT OF THE FORMULA -O-R4, WHEREIN R4 IS EITHER HYDROGEN; LOWER ALKYL; OR LOWER ACYL HAVING NO MORE THAN 5 CARBON ATOMS, THE ALKYLENE GROUP CONTAINING 3-20 CARBON ATOMS, AND BEING OPTIONALLY BROKEN BY ONE OR MORE OXYGEN BRIDGES, OR A PHYSIOLOGICALLY ACCEPTABLE SALT THEREOF. SUCH COMPOSITIONS ARE USEFUL AS X-RAY CONTRAST COMPOSITIONS AND ARE ADMINISTERED TO THE BODY OF THE TEST OBJECT FOR THE X-RAY VISUALIZATION OF THE BODY CAVITY.
