Indication and contraindication of contrast radiography in animals

Indication and contraindication of Contrast radiography in animals will be explained in this post.

Indication of contrast radiography

Structures or organs can be evaluated more effectively for their size, shape and position by use of contrast radiography.

Valuable information can be gained regarding serosal and mucosal surfaces of hollow organs or their contents which otherwise not apparent on plain radiography.

In some instances some idea on function of organ can be formed by use of contrast radiography.

Contraindication of contrast radiography

Contrast radiography agents may be chemotaxic or local reaction. it may be cause allergic responses, urticaria, head jecks, muscle fasciculations etc. Hyper osmolarity of tri-iodinated compounds is the major contributing factor.

Systemic or hypersensitive reaction may be caused. these may occur even in small dose of contrast agent but increasing the dose increases the incidence.  Mediator release or Histamine release, antigen-antibody reaction or due to involvement of acute activation system. Patients with preexisting cardiac or renal abnormalities, diabetes mellitus and dehydration are at high risk. Premeditation with steroids reduces the adverse effects.
