| Abstract | With high frequency ultrasound systems becoming more widely available, ultrasonic imaging of the murine heart has attracted increasing interest. Typically, standard gray scale imaging has been used to characterize ventricular morphology and function. Prior studies in large animals and humans based on relatively low frequency insonation have shown dial ultrasonic strain and strain rate imaging can be a more sensitive measure of myocardial function. Therefore, in this study, the feasibility of measuring ultrasonic strain and strain rate in the murine heart was tested. Moreover, normal murine strain and strain rate values were established and the ability of these measures to detect abnormal myocardial function was verified. In both mice with normal and abnormal myocardial function the measurement of strain and strain rate was shown to be feasible. Moreover, these cardiac deformation indices were shown to be more sensitive than standard gray scale measurements for the detection of functional abnormalities. Ultrasonic strain and strain rate imaging thus offers a new and more sensitive approach for the non-invasive assessment of murine myocardial function. |

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.
