perfusionsMRICT

perfusionsMRICT refers to Magnetic Resonance Imaging (MRI) perfusion with contrast enhancement. This advanced neuroimaging technique is primarily used to assess blood flow within the brain and to detect areas of reduced perfusion, which can indicate a lack of oxygenated blood. The procedure involves injecting a contrast agent, typically gadolinium-based, intravenously during the MRI scan. As the contrast agent circulates through the brain's blood vessels, the MRI scanner captures images that track its passage and distribution.

The data generated by perfusionsMRICT allows clinicians to quantify parameters such as cerebral blood volume (CBV), cerebral blood flow (CBF), mean transit time (MTT), and time to peak (TTP). These quantitative measurements are crucial for diagnosing and managing conditions like acute ischemic stroke, where rapid identification of affected brain tissue is vital for timely treatment. It can also be used in the evaluation of brain tumors to assess their vascularity and response to therapy, and in the investigation of other cerebrovascular diseases. The contrast-enhanced nature of the imaging provides valuable information about the integrity of the blood-brain barrier and the patency of blood vessels.
