Rapid technical advances in medical imaging, including its growing application to
drug/gene therapy and invasive/interventional procedures, have attracted significant
interest in close integration of research in life sciences, medicine, physical sciences
and engineering. This is motivated by the clinical and basic science research requirement
of obtaining more detailed physiological and pathological information about the
body for establishing localized genesis and progression of diseases.
The prefrontal network plays an important role in behaviors that require an integration of thought with emotion and motivation. There is no simple formula for summarizing the diverse functional affiliations of the prefrontal network. Its integrity appears important for the simultaneous awareness of context, options, consequences, relevance, and emotional impact so as to allow the formulation of adaptive inferences, decisions, and actions.
(BQ) Part 2 book "Brain Imaging with MRI and CT" presents the following contents: Abnormalities without significant mass effect, primarily extra axial focal space occupying lesions, primarily intra axial masses, intracranial calcifications.
Brain Abscess (See also Chap. 376) Brain abscess often occurs without systemic signs. Almost half of patients are afebrile, and presentations are more consistent with a space-occupying lesion in the brain; 70% of patients have headache, 50% have focal neurologic signs, and 25% have papilledema. Abscesses can present as single or multiple lesions resulting from contiguous foci or hematogenous infection, such as endocarditis. The infection progresses over several days from cerebritis to an abscess with a mature capsule.
