Magnetic resonance imaging is emerging as a valuable tool for the urgent evaluation of patients with acute stroke. This review focuses on the applications of magnetic resonance imaging in the diagnosis and management of intracranial hemorrhage. The biophysical properties of blood in the neuroaxis and the magnetic resonance imaging evolution of intracranial bleeding are reviewed. The potential applications of magnetic resonance imaging in the evaluation and therapy of specific types of intracranial hemorrhage are discussed. Emphasis is made on the superiority of magnetic resonance imaging in detecting intracranial hemorrhage and ischemic stroke. Although there is some hesitation to perform magnetic resonance imaging to evaluate acute intracranial hemorrhage, there is strong evidence that magnetic resonance imaging is not inferior to computerized tomography in this clinical setting. In the era of acute stroke intervention, magnetic resonance imaging offers significant advantages over computed tomography.

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

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 Stimulation (TMS).

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,...

Imaging Studies IV: Magnetic Resonance Imaging

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...
