Researchers use novel three-dimensional imaging technique
October 26, 2006FINDINGS: Using an innovative three-dimensional imaging technique, a team of UCLA researchers have tracked how Alzheimer's disease spreads through the hippocampus - the area of the brain linked with memory - in a pattern consistent with the known trajectory of neurofibrilliary tangle dissemination, an accumulation of diseased proteins in the brain cells. They found that three areas within the hippocampus of Alzheimer's patients show more atrophy compared with those in patients having amnestic mild cognitive impairment (MCI), a recently defined condition characterized by memory decline but that leaves other daily living activities unimpaired, and which immediately precedes Alzheimer's.
IMPACT: The technique is significant because it makes it possible to track the progression of Alzheimer's disease in live patients. This will be crucial in evaluating the effectiveness of drugs that fight Alzheimer's when they become available for clinical trials.

Imaging Technique Current Events and Imaging Technique News RSSThe humble beginnings of a king
Tyrannosaurus rex and related large carnivorous dinosaurs together form the family Tyrannosauridae. A long forgotten fossil skull in the collections of the Natural History Museum in London has now provided crucial clues to the early stages of the lengthy evolutionary history of these fearsome predators.
Adapting Space-Industry Technology to Treat Breast Cancer
Researchers at Rush University Medical Center and Argonne National Laboratory are collaborating on a study to determine if an imaging technique used by NASA to inspect the space shuttle can be used to predict tissue damage often experienced by breast cancer patients undergoing radiation therapy.
Researchers develop innovative imaging system to study sudden cardiac arrest
A research team at Vanderbilt University has developed an innovative optical system to simultaneously image electrical activity and metabolic properties in the same region of a heart, to study the complex mechanisms that lead to sudden cardiac arrest.
Faulty 'wiring' in the brain triggers onset of schizophrenia
A new study by researchers at the Institute of Psychiatry (IoP), King's College London has discovered abnormalities in the white matter of the brain that seem to be critical for the timing of schizophrenia.
Regulating emotion after experiencing a sexual assault
After exposure to extreme life stresses, what distinguishes the individuals who do and do not develop posttraumatic stress disorder (PTSD)?
Lung scintigraphy more reliable than CTA in excluding pulmonary embolism in pregnant patients
A medical imaging procedure known as lung scintigraphy may be more reliable than pulmonary CT angiography (CTA) for identifying or excluding pulmonary embolism (PE) in pregnant patients.
tudy: The new buzz on detecting tinnitus
It's a ringing, a buzzing, a hissing or a clicking - and the patient is the only one who can hear it. Complicating matters, physicians can rarely pinpoint the source of tinnitus, a chronic ringing of the head or ears that can be as quiet as a whisper or as loud as a jackhammer.
Combination of PET/CT tests can expedite diagnosis of lung cancer in a fast-track setting
Research published in the October 2009 issue of the Journal of Thoracic Oncology has found an effective combination of positron emission tomography (PET)/computed tomography (CT) (PET/CT) tests to diagnose lung cancer in a "fast-tracked" outpatient setting.
Molecular imaging holds promise for early intervention in common uterine cancer
A promising new molecular imaging technique may provide physicians and patients with a noninvasive way to learn more information about a type of cancer of the uterus lining called "endometrial carcinoma"-one of the most common malignant female tumors.
Pancreatic fat levels may help predict diabetes, UT Southwestern researchers say
Researchers have long suspected that overweight people tend to have large fat deposits in their pancreases, but they've been unable to confirm or calculate how much fat resides there because of the organ's location. Until now.

Introduction to Functional Magnetic Resonance Imaging: Principles and Techniques by Richard B. Buxton (Author) Functional Magnetic Resonance Imaging (fMRI) has become a standard tool for mapping the working brain's activation patterns, both in health and in disease. It is an interdisciplinary field and crosses the borders of neuroscience, psychology, psychiatry, radiology, mathematics, physics and engineering. Developments in techniques, procedures and our understanding of this field are expanding rapidly. In this second edition of Introduction to Functional Magnetic Resonance Imaging, Richard Buxton - a leading authority on fMRI - provides an invaluable guide to how fMRI works, from introducing the basic ideas and principles to the underlying physics and physiology. He covers the relationship between fMRI and other imaging techniques and includes a guide to the statistical analysis of fMRI data.... |

Hyperspectral Imaging: Techniques for Spectral Detection and Classification by Chein-I Chang (Author) Hyperspectral Imaging: Techniques for Spectral Detection and Classification is an outgrowth of the research conducted over the years in the Remote Sensing Signal and Image Processing Laboratory (RSSIPL) at the University of Maryland, Baltimore County. It explores applications of statistical signal processing to hyperspectral imaging and further develops non-literal (spectral) techniques for subpixel detection and mixed pixel classification. This text is the first of its kind on the topic and can be considered a recipe book offering various techniques for hyperspectral data exploitation. In particular, some known techniques, such as OSP (Orthogonal Subspace Projection) and CEM (Constrained Energy Minimization) that were previously developed in the RSSIPL, are discussed in great detail.... |
