Which radiology procedure allows visualization of blood flow in the brain?

Cerebral angiography is a specialized radiology procedure that provides detailed images of the blood vessels in the brain, allowing for visualization of blood flow. This technique involves the injection of a contrast agent into the blood vessels, usually through a catheter that is threaded from a larger artery. This contrast material enhances the visibility of the arteries in imaging studies, enabling the detection of abnormalities such as blockages, aneurysms, or malformations.

The procedure is critical for diagnosing various cerebrovascular conditions and for planning further treatment options. The multi-dimensional images obtained during cerebral angiography allow for an accurate assessment of the vascular anatomy and pathology in the brain, which is essential for effective patient management.

Other options listed involve procedures related to vascular interventions but do not directly correspond to visualizing blood flow specifically in the brain. Thrombolytic therapy is a treatment aimed at dissolving blood clots but does not visualize blood flow. Endovascular coiling is used to treat aneurysms by placing coils within them rather than imaging blood flow directly. Carotid angioplasty focuses on the carotid arteries leading to the brain, but does not provide the comprehensive visualization of cerebral vasculature that cerebral angiography offers.
