Changes in ovarian blood flow during the preovulatory period are essential for ovulation. Doppler ultrasonography has been used in humans and large animals to assess ovarian hemodynamics and perfusion. A protocol is presented for applying Doppler ultrasonography to evaluate ovarian hemodynamics during the preovulatory and periovulatory phases in mice.

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Tools used for visualizing vascular regeneration require methods for contrasting the vascular trees. This film demonstrated a delicate injection technique used to achieve optimal contrasting of the vascular trees and illustrate the potential benefits resulting from a detailed analysis of the resulting specimen using µCT and histological serial sections.
FAQs
These approaches generate vascular information from different measurable properties. Magnetic resonance angiography, computed tomography angiography, and Doppler ultrasound can distinguish vessels or blood flow through differences in blood movement, tissue properties, or injected contrast agents. Their complementary signals allow investigators to examine vascular structure and circulation from different perspectives rather than relying on a single imaging principle.
Contrast agents and flow-sensitive signals improve the separation between vessels, surrounding tissue, and moving blood. In computed tomography angiography, an injected contrast agent contributes to vessel visualization, while other approaches use blood movement or tissue properties. These distinctions help produce maps that support assessment of vascular structure, circulation, and changes in perfusion.
Neurovascular coupling describes the relationship between neural activity and cerebral blood flow. Vascular imaging can investigate this relationship by measuring changes in circulation alongside patterns of brain activity or vascular response. This provides a way to study how blood supply relates to nervous-system function and to examine whether disease alters that relationship.
Measurements can reveal changes in perfusion, vascular structure, and blood flow in the brain or body. In neuroscience, these findings help researchers examine circulation-related abnormalities and follow vascular changes over time. Because the methods support increasingly precise, noninvasive assessment, they can contribute to evaluating brain health and monitoring disease progression or treatment response.
A study can select magnetic resonance angiography, computed tomography angiography, or Doppler ultrasound according to the vascular information it needs, such as vessel mapping, blood-flow assessment, or perfusion changes. The resulting images and measurements are then interpreted in relation to the research question, whether it concerns neural activity, vascular structure, disease, or response to treatment.
It is particularly useful when investigators need to examine stroke, aneurysms, or vascular malformations, as well as broader changes in cerebral circulation. The techniques can support disease-progression studies and treatment-response assessments while also providing context for neurovascular coupling. Together, these applications connect observable vascular changes with brain health and neurological research outcomes.
