Cerebral sparganosis in children is an extremely rare disease of central nervous system, and caused by a tapeworm larva from the genus of Spirometra. In this study, we discussed and summarized epidemiological, clinical and MR imaging characteristics of eighteen children with cerebral sparganosis for a better diagnosis and treatment of the disease.

MRI has been increasingly used for detailed visualization of the fetus in utero as well as pregnancy structures. Yet, the familiarity of radiologists and clinicians with fetal MRI is still limited. This article provides a practical approach to fetal MR imaging. Fetal MRI is an interactive scanning of the moving fetus owed to the use of fast sequences. Single-shot fast spin-echo (SSFSE) T2-weighted imaging is a standard sequence. T1-weighted sequences are primarily used to demonstrate fat, calcification and hemorrhage.

The Sixth Edition of Dr. Haines's best-selling neuroanatomy atlas features a stronger clinical emphasis, with significantly expanded clinical information and correlations. More than 110 new images--including MRI, CT, MR angiography, color line drawings, and brain specimens--highlight anatomical-clinical correlations. Internal spinal cord and brainstem morphology are presented in a new format that shows images in both anatomical and clinical orientations, correlating this anatomy exactly with how the brain and its functional systems are viewed in the clinical setting.

Cerebrovascular diseases have an enormous and increasing impact on societies: they rank among the leading causes of death, are often associated with chronic handicap, and cause high costs for primary treatment, rehabilitation and chronic care. The advent of treatment options such as reperfusion therapies and, to a lesser degree, neuroprotective strategies on the one hand, and growing means to enhance rehabilitation and functional plasticity on the other hand, urges physicians to diagnose stroke subtypes as early and precisely as possible.

Since the advent of magnetic resonance (MR) imaging, systems with amagnetic field intensity of 1.5 tesla (T) have been deemed the gold standard for different clinical applications in all body areas. Ongoing advances in hardware and software have made theseMRsystems increasingly compact, powerful and versatile, leading to the development of higher magnetic field strength MRsystems (3.0 T) for use in clinical practice and for research purposes. As usually occurs with a new technology, 3.0 T MR imaging units will probably follow the same development trends in the years to come....

This book is the result of many years of clinical and academic interest in diffusion-weighted MR (DW) imaging of the brain. Researchers and clinicians at the University of Rochester started to collect DW images of a spectrum of abnormalities affecting the brain immediately after this technique became available. Several case series with clinical and radiographic correlations have been presented at the annual meetings of the American Society of Neuroradiology and the Radiological Society of North America via posters and scientific reports....

In Chapter 1 we present in detail a framework for fully automated brain tissue classification. The framework consists of a sequence of fully automated state of the art image registration (both rigid and nonrigid) and image segmentation algorithms. Models of the spatial distribution of brain tissues are combined with models of expected tissue intensities, including correction of MR bias fields and estimation of partial voluming. We also demonstrate how this framework can be applied in the presence of lesions....

In this experiment, there was one type of real brain MR images. In order to evaluate the performance of the UVSRG, the widely used c-means method (also known as k-means) is used for comparative analysis. The reason to select the c-means method is because it is a spatial-based pattern classification technique. In order to make a fair comparison, the implemented c-means method always designates the desired target signature d as one of its class means with d fixed during iterations.

The algorithm of K-means clustering was employed to mainly classify the results of region segmentation in the previous stage. The brain MR images were classified into three categories, respectively GM, WM, and CSF. Because there were many fragmentary regions, it was necessary to classify all the regions, in which all the regions were divided into three categories, it was assumed that K=3, and the region was regarded as a unit to conduct the algorithm of K-means clustering.

Magnetic resonance spectroscopy (MRS), unlike conventional magnetic resonance imaging (MRI), provides information on the brain’s chemical environment (rather than neuroanatomical structure) and the data are most commonly presented as line spectra. This capacity for determining brain metabolite concentrations provides the basis for clinical investigation of, and differentiation between, neurological and neurosurgical conditions.

Congenital heart disease in newborns is associated with global impairment in development. We characterized brain metabolism and microstructure, as measures of brain maturation, in newborns with congenital heart disease before they underwent heart surgery. Methods We studied 41 term newborns with congenital heart disease — 29 who had transposition of the great arteries and 12 who had single-ventricle physiology — with the use of magnetic resonance imaging (MRI), magnetic resonance spectroscopy (MRS), and diffusion tensor imaging (DTI) before cardiac surgery....
