Advanced MRI techniques

Ebook "BetaSys: Systems biology of regulated exocytosis in pancreatic β-cells" gives a snapshot of the field at the threshold of a possible explosion in knowledge. We introduce recent advances in observational techniques, ranging from genetic epidemiology via proteomics to multi-parameter cell sensoring, MRI, ET and nanoparticle-based cell imaging.

Conventional fat quantification methods for rotator cuff muscles have various limitations, such as inconsistent reliabilities of the Goutallier grades and need for advanced techniques in quantitative MRI sequences. We aimed to examine a threshold-based fat quantification method in the supraspinatus muscle on standard T1- weighted MR images and compare the threshold-based method with Goutallier grades and MR spectroscopy.

Although radiotherapy is a key component of curative-intent treatment for locally advanced, unresectable non-small cell lung cancer (NSCLC), it can be associated with substantial pulmonary toxicity in some patients. Current radiotherapy planning techniques aim to minimize the radiation dose to the lungs, without accounting for regional variations in lung function.

The methylation status of oxygen 6-methylguanine-DNA methyltransferase (MGMT) promoter has been associated with treatment response in glioblastoma(GBM). Using pre-operative MRI techniques to predict MGMT promoter methylation status remains inconclusive.

Definitive chemoradiotherapy is standard of care in locally advanced cervical cancer (LACC). Both toxicity and local relapse remain major concerns in this treatment. We hypothesize that a magnetic resonance imaging (MRI) based redefining of the radiotherapeutic target volume will lead to a reduction of acute and late toxicity.

Functional Magnetic Resonance Imaging of brain is typically called fMRI. It has become a fundamental modality of imaging at any MRI suite of service center or hospital. Our book has been compiled with the aim of incorporating a wide range of applied neuropsychological evaluation methods. It is aimed at those who are embarking on neuropsychological research projects, as well as relatively experienced psychologists and neuroscientists who might wish to further develop their experiments.

Scientists have long relied on the power of imaging techniques to help them see things invisible to the naked eye and thus advance scientific knowledge. In medicine, X-ray imaging and magnetic resonance imaging (MRI) have added a level of insight beyond traditional lab tests into the workings of the human body and identification of disease at its earliest stages. Microscopy, which has been in use since the sixteenth century, is now powerful enough to detect, identify, track, and manipulate single molecules on surfaces, in solutions, and even inside living cells....

Computed tomography (CT) is the mainstay of cancer imaging outside of the central nervous system. Advances in multidetector CT (MDCT) technology have had a profound impact on its diagnostic capabilities. Such techniques as multiphase, single breath-hold imaging, CT angiography (CTA), volume rendering and virtual colonography owe their success to the development of multidetector arrays with continuously moving gantries.

The first edition of Handbook of MRI Technique was a resounding success. The rapidly increasing number of radiographers and technologists entering the modality, coupled with the development of education and training courses worldwide, has resulted in an increased demand for MRI books of any shape and size. The education of radiographers, technologists and radiologists often lags behind the rapid technological advances in MR.

Functional magnetic resonance imaging (fMRI) represents one of the most advanced and enlightening functional imaging techniques that has ever been developed. The past ten years (1990–2000) of scientific research has been designated the decade of the brain and has led to numerous technological developments and the establishment of fundamental clinical protocols to understand brain functions. The next decade, the beginning of the 21st century, will continue the great momentum of brain research.

The goals of experimental neuroscience research are fundamentally to gain mechanistic understanding of the pathology of disease in order to identify appropriate targets for potential pharmacological intervention and evaluation of putative therapies. With the advances in gene manipulation and transgene technologies, we have unprecedented ability to generate animal models of disease that more closely mimic the clinical conditions. Noninvasive techniques capable of investigating altered pathophysiologies are now of paramount importance.

Medical imaging has been transformed over the past 30 years by the advent of computerized tomography (CT), magnetic resonance imaging (MRI), and various advances in x-ray and ultrasonic techniques. An enabling force behind this progress has been the (so far) exponentially increasing power of computers, which has made it practical to explore fundamentally new approaches.

The history of the development of prostate biopsy has changed significantly from random biopsies, to systematic to extended biopsy schemes. Systematic sextant biopsies, even when laterally directed, do not provide adequate sampling of the prostate. Ultimately the sextant biopsy technique has now become obsolete in favour of more extended biopsy protocols. To date there is no consensus on the optimal number of cores without significantly increasing morbidity but it has been shown that as prostate gland size increases, the yield of sextant biopsy has decreased (Karakiewicz et al.

Consequently, it is necessary to integrate the information of all the spectral images to classify tissues. Multi-spectral image processing techniques [1-3] are hence employed to collect spectral information for classification and of clinically critical values. In this paper, a new classification approach was proposed, it is called unsupervised Vector Seeded Region Growing (UVSRG). The UVSRG mainly select seed pixel vectors by means of standard deviation and relative Euclidean distance.

Velocity encoded phase-contrast magnetic resonance imaging (VE-PC MRI) is another imaging technique used to noninvasively measure Achilles tendon strain and changes in its force-displacement relationship concomitant with chronic unloading and subsequent recuperation. This technique will be reviewed in terms of its ability to quantify the Achilles tendon Young’s modulus (MPa) from a stress-strain curve.
