Ultrafast Blood T1 Measurement Using Golden Angle Rotated Spiral k‐t Sparse Parallel Imaging (GASSP): Evaluations in Both Pre‐ and Post‐Contrast Conditions

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Blood T1 is a key parameter for hemodynamic quantification in both non‐contrast‐ and contrast‐enhanced imaging. Individual vessel T1 has been measured using a modified Look–Locker scheme with multi‐shot EPI or FLASH in high spatial resolution, requiring ∼1 min.

Simultaneous Volumetric T1 and T2 Mapping With Blood‐ and Fat‐Suppression in Abdominal Aortic Aneurysms

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and validate a protocol for simultaneous volumetric T1 and T2 mapping with blood‐ and fat‐suppression, and apply it to patients with abdominal aortic aneurysms (AAA) to assess tissue characteristics. Methods A spoiled gradient echo (SPGR) variable flip angle (VFA) acquisition was modified with preparation modules to suppress

Simultaneous Cerebral Blood Flow and Cerebrovascular Reactivity Obtained From Novel Multi‐Band Multi‐Echo Pseudo‐Continuous Arterial Spin Labeling (M2‐PCASL) Sequence: A Test–Retest Reliability Study

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose We aim to assess the reliability of cerebral blood flow (CBF) and cerebrovascular reactivity (CVR) obtained simultaneously from a novel multi‐band pseudo‐continuous arterial spin labeling (M2‐PCASL) sequence and hypercapnic gas challenge, to examine factors influencing CBF variability, and to evaluate the impact of carbon dioxide (CO2)

Physiological Interpretation of the Lactate to Pyruvate AUC Ratio for Hyperpolarized [1‐13C]‐Pyruvate Studies

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To explore the relationship between potentially rate‐limiting steps in lactate production and the lactate area‐under‐the‐curve (AUC) to pyruvate AUC ratio for analysis of hyperpolarized (HP) [1‐13C]‐pyruvate data. Theory and Methods Simplifying assumptions are introduced to a pharmacokinetic (PK) model with three physical compartments ...

Respiration Can Trigger Cerebrovascular Reactivity: A Novel Method to Quantify Cerebrovascular Resistance Dynamics Using Real‐Time Phase‐Contrast MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To directly quantify respiration‐driven cerebrovascular resistance dynamics (CRD) using a gas‐free MRI framework based on the internal‐to‐external artery carotid flow ratio (ratio_Q). Theory and Methods Two independent datasets (n = 10 and n = 17) were used to evaluate repeatability and to compare breathing conditions.
