The process of converting very light nuclei into heavier nuclei is also accompanied by the conversion of mass into large amounts of energy, a process called fusion. The principal source of energy in the sun is a net fusion reaction in which four hydrogen nuclei fuse and ultimately produce one helium nucleus and two positrons. A helium nucleus has a mass that is 0.7% less than that of four hydrogen nuclei; this lost mass is converted into energy during the fusion. This reaction produces about...

Functional Neuroimaging Using Ultrasonic Blood-brain Barrier Disruption and Manganese-enhanced MRI

A technique is described for broadly opening the blood-brain barrier in the mouse using microbubbles and ultrasound. Using this technique, manganese can be administered to the mouse brain. Because manganese is an MRI contrast agent that accumulates in depolarized neurons, this approach enables imaging of neuronal activity.
FAQs
The system uses spatial tracking to relate the position of the ultrasound view to the patient’s anatomy, then co-registers that live information with a previously acquired MRI scan. This alignment lets the operator identify where an MRI-suspicious region corresponds to the current ultrasound examination, supporting more precise localization during assessment or intervention.
MRI contributes high-contrast anatomical information, while ultrasound supplies real-time visualization during the examination or procedure. Their combination allows clinicians to interpret a suspicious region in the context of both detailed prior imaging and current anatomy. This complementary workflow can support procedural targeting and planning more effectively than depending on either information source alone.
Spatial tracking provides the positional information needed to connect the moving ultrasound view with the corresponding location on the MRI scan. Without this relationship, an operator could not reliably correlate a previously identified abnormality with the patient’s anatomy during the live examination. The tracking component therefore supports accurate localization and guides attention toward the relevant region.
During a targeted prostate biopsy, the clinician uses MRI-visible lesions as the focus for sampling rather than relying only on systematic needle placement. Previously acquired MRI information is correlated with live ultrasound, allowing the operator to direct the biopsy toward the suspicious region. This approach is intended to improve diagnostic precision by linking imaging findings with tissue sampling.
The approach is particularly relevant when MRI identifies a lesion that requires focused evaluation. By directing sampling toward that MRI-visible target, the clinician can use the suspicious imaging finding to guide needle placement instead of relying solely on a systematic distribution. Its value lies in connecting lesion localization with the biopsy procedure and supporting more targeted diagnostic assessment.
The technique also supports image-guided interventions and broader procedural planning. Correlating MRI anatomy with live ultrasound can help clinicians localize abnormalities while working with current visual information, rather than interpreting the MRI separately from the procedure. In this context, the method may contribute to diagnostic precision and more personalized patient care across image-guided medical workflows.
