The procedure commonly referred to as angiography among the public is performed both for diagnostic purposes (angiography) and for therapeutic purposes. Angiography refers to the imaging of the body’s blood vessels. In this procedure, a substance known as a contrast agent, which makes the vessels visible, is injected into the bloodstream, and images known as angiograms are obtained. Through angiography, the vessels supplying organs are visualized, allowing for the diagnosis of vascular diseases or for obtaining diagnostically relevant information concerning the organs supplied by these vessels.
The therapeutic form of angiography is classically known as angioplasty. This procedure is performed to reopen narrowed or completely blocked vessels using specialized instruments such as balloons or stents.
In light of these explanations, since neither angiography nor angioplasty involves eating, drinking, or nourishment in any form, undergoing these procedures does not invalidate the fast.
