Magnetic resonance imaging (MRI) as a clinical investigation became available in the early 1980s. Since then this method has proven to be a valuable additional diagnostic tool in the recognition and delineation of space-occupying lesions of the brain (1, 2, 3, 5). In the present study the...
Magnetization-transfer MRI provides proton-density contrast in brain while saturating extracellular free water protons.(a)Comparison of M0map (M0), proton-density-weighted MRI with MT (α15MT), R1map (R1), T1-weighted MRI without (α70) and with MT (α70MT), MT ratio map (α70MTR).(b...
Brain tumor detection using MRI images has been a focal point of research due to MRI’s capability to provide detailed and high-contrast images. Various traditional image processing techniques, including segmentation and feature extraction, have been employed to differentiate between normal and abnormal ...
For the initial imaging of an acute or progressively worsening mental status change in a patient with a known intracranial process (mass, recent hemorrhage, recent infarct, central nervous system infection, etc), CT head without IV contrast, MRI head without and with IV contrast, or MRI head ...
For each animal, the fUS imaging experiment (without contrast agents) was first performed. The ULM experiment was then performed in exactly the same imaging plane. ULM acquisition and processing ULM acquisitions were performed similarly to the methods described previously28, but using a continuous inj...

MR spectroscopy may be useful even when the routine MRI is normal. Proton MR spectroscopy of the brain is abnormal in neonates exposed to HIV in utero, although this does not differentiate infected children from uninfected children. A non-specific amino acid peak in the 2.1–2.6 ppm area ...
Recently, imparied meningeal lymphatic drainage in patients with idiopathic Parkinson’s disease has been described with contrast enhanced MR35. While MRI can allow for noninvasive in vivo evaluation of MLVs for these pathologies29, this has previously been achieved only through use of intravenous ...
Decision-makers objectively commit to a definitive choice, yet at the subjective level, human decisions appear to be associated with a degree of uncertainty. Whether decisions are definitive (i.e., concluding in all-or-none choices), or whether the under
