Brain Imaging

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Imaging Studies for Cardiovascular System V: CT

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Imaging Studies for Cardiovascular System IV: CMRI

Imaging Studies for Cardiovascular System IV: CMRI

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Critical Care Medicine

Background:

Patients surviving cardiac arrest often experience disorders of consciousness post-resuscitation.
Predicting long-term neurological outcome necessitates comprehensive assessments, with brain imaging being crucial.

Approach:

This review provides an overview of neuroimaging modalities like computed tomography (CT) and magnetic resonance imaging (MRI).
It examines the current uses and limitations of both qualitative and quantitative imaging techniques for outcome prediction.

Key Points:

Qualitative CT and MRI interpretation is common but suffers from low inter-rater reliability and specificity.
Quantitative methods, such as CT gray-white ratio and MRI diffusion-weighted imaging, show potential but need standardization.
Further research is essential to refine and standardize imaging analysis for improved accuracy.

Conclusions:

Brain imaging is vital for assessing neurological injury severity following cardiac arrest.
Standardization of qualitative and quantitative imaging analysis is a critical future direction.
Emerging imaging techniques and analytical methods promise advancements in predicting patient outcomes.
