Structural MRI and Brain Development

2005
Magnetic resonance imaging (MRI) scans provide exceptionally detailed information on how the human brain changes throughout childhood, adolescence, and into old age. We describe several approaches for understanding developmental changes in brain structures based on MRI.

Structured reporting of MRI for perianal fistula

Abdominal Radiology, 2018
The purpose of this article is to review MRI technique, relevant anatomy, and MRI classification systems for the assessment of perianal fistulising disease. We present a stepwise approach to the assessment of perianal fistulas on MRI utilizing a systematic reporting format.MRI is invaluable for the assessment of perianal fistulas.

Structured reporting in knee MRI

Skeletal Radiology
Structured reporting in knee MRI represents a transformative advancement in musculoskeletal radiology, promising enhanced clarity and consistency in evaluating the knee's complex anatomy-menisci, ligaments, cartilage, and bone. This review article explores the foundations, evolution, and clinical applications of structured reporting, with a special ...

MRI to assess renal structure and function

Current Opinion in Nephrology and Hypertension, 2011
In addition to excellent anatomical depiction, MRI techniques have expanded to study functional aspects of renal physiology, such as renal perfusion, glomerular filtration rate (GFR) or tissue oxygenation. This review will focus on current developments with an emphasis on clinical applicability.The method of GFR determination is largely heterogeneous ...

Robust segmentation of brain structures in MRI

2009 IEEE International Symposium on Biomedical Imaging: From Nano to Macro, 2009
A novel method for the segmentation of brain structures combining registration-based and EM-based approaches is proposed. To address the issue of intensity variation within brain structures, we propose a method for creating spatial prior corresponding very well with the new subject anatomy, referred to as subject-specific atlas.

Integrated 4D visualization of MRI and structure

ACM SIGGRAPH 2006 Research posters on - SIGGRAPH '06, 2006
We describe our preliminary research on integrating MRI video with a 3D surface scan of a face. Our approach first extracts contours of a video by using snakes [KWT87, LL93]; then the outline structure of the video is matched with a close matching contour on the 3D face structure.

Mood disorders – review of structural MRI studies

Acta Neuropsychiatrica, 2003
Background: Mood disorders are related to considerable morbidity and mortality, and although there is little doubt that they are brain-based disorders, their neural correlates still remain elusive.

Structural MRI Changes of the Brain in Depression

Clinical EEG and Neuroscience, 2004
For many years, investigators have been trying to identify the neuroanatomical structures responsible for the development of neuropsychiatry disorders, specifically depression and schizophreniform disorders. The available data were based on observations made in neurological patients who developed a psychiatric comorbid disorder following the neurologic

No-Reference Image Quality Metrics for Structural MRI

Neuroinformatics, 2006
Neuroimagery must be visually checked for unacceptable levels of distortion prior to processing. However, inspection is time-consuming, unreliable for detecting subtle distortions and often subjective. With the increasing volume of neuroimagery, objective measures of quality are needed in order to automate screening.

Structural MRI in Alzheimer’s Disease

2020
Abstract Structural magnetic resonance imaging (MRI) is a powerful tool to visualize and quantitate morphological and pathological features of the aging brain. Most work that has used structural MRI to study Alzheimer’s disease (AD) focused on the spatial distribution of atrophic changes associated with disease.
