An MRI dynamic angiography (also known as dynamic contrast-enhanced MR angiography) is performed to visualize blood vessels and assess blood flow in real-time. It uses a contrast agent and takes a series of rapid images over time, allowing radiologists to observe how blood moves through vessels and organs.

Here’s why it's done:
- Assess Vascular Health: It helps in diagnosing conditions related to blood flow, such as aneurysms, arterial blockages, or vascular malformations.
- Detect Arterial Stenosis: It can detect narrowing of blood vessels (stenosis), which can cause a reduction in blood supply to organs and tissues.
- Aneurysm Evaluation: It helps in detecting and characterizing aneurysms in blood vessels by showing how blood flows into the affected area.
- Pre-surgical Planning: Surgeons can use the dynamic angiography to plan interventions by understanding the exact anatomy of blood vessels.
- Tumor Assessment: In cancer cases, dynamic MRI can show how tumors are vascularized, giving information about the tumor’s aggressiveness and response to treatments.
Since it's non-invasive and provides detailed real-time imaging of blood flow, it is a preferred method in many cases over conventional angiography.
