Syncope
Fainting, or syncope, is a very mild form of shock that sometimes occurs when fright, pain, or unpleasant events are beyond the coping ability of the patient's nervous system.
Anaphylactic
Allergic shock, also called anaphylaxis or anaphylactic shock, occurs when individuals are exposed to foreign substances to which they are sensitized

Ionic Media vs. Non-Ionic Media?
non-ionic contrasts have low osmolarity, with low iodine concentration and when injected are less toxic and are less likely to result in adverse reactions
Toxicity of a contrast medium is related to:
