| Abstract | Despite the progress in fast scan MRI techniques, it has not been possible to routinely image the heart rapidly enough so as to collect all image data during one breath-hold. Cardiac images are therefore degraded by respiratory motion during several minutes of data acquisition. Fast scan images also have limited SNR and inadequate myocardium-to-chamber contrast. The purpose of this work was to address these limitations by blood suppression, centric or centric-like view ordering, and data acquisition in diastole with 2DFT and 3DFT gradient echo acquisition. High resolution black-blood cardiac images were acquired. The endocardial surface is very well delineated. In a series of 13 volunteer studies these methods have consistently provided superior quality visualization of intraventricular structures. The authors believe the images are a significant improvement over previous results generated with gradient echo and echo-planar techniques, and rival high quality gated spin-echo results.< |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
