Conceptual framework of venous perfusion source mapping in the superior cerebral veins. Credit: Nature Communications (2025). DOI: 10.1038/s41467-025-59108-3 ...

Introduction: Prolonged venous outflow (PVT+) is a surrogate marker for venous outflow. The PVT is defined as the presence or absence of time-to-maximum >= 10 seconds timing in either the superior ...

Yet, perfusion MRI approaches are not easy to implement for whole-brain research in mice due to their small size. This non-invasive, repeatable, simple hypoxia BOLD-MRI method is capable of ...

However, as many people with splenic vein thrombosis do not present with obvious symptoms, imaging tests may be essential for diagnosis. They allow a healthcare professional to look for blockages ...

Using magnetic resonance imaging in patients with β-thalassemia, researchers confirmed that there’s an increase in cerebral blood perfusion secondary to anemia severity, leading to a new theory ...

Routinely trade-offs between the spatio-temporal resolution, volume coverage and SNR are done in first pass cardiac perfusion MRI due to the restricted imaging acquisition window (usually of the order ...

KTVU 2 Investigates: MRI safety after 'freak accident' A "freak accident" left a nurse crushed by an MRI at the Kaiser Permanente hospital in Redwood City. KTVU 2 Investigates. REDWOOD CITY, Calif.

The emerging advantages of positron-emission tomography (PET) myocardial perfusion imaging (MPI) for coronary artery disease (CAD) diagnosis and assessment of cardiovascular event risk has ...

Doctors may use a heart perfusion imaging scan to check a person's heart health and function. Learn the risks, procedure, and how to prepare for this test.
