Abstract | OBJECTIVE: To evaluate the clinical value of transvaginal elastography (TVES) in diagnosing cervical malignancies by detecting changes of tissue stiffness. METHODS: One hundred and ten consecutive patients with cervical lesions were enrolled. Pathological results were used as the gold standards. TVES was employed to detect the stiffness changes of the cervix. Strain ratio was calculated and compared between the benign and malignant lesions. Depth of invasion into stromas of 56 cases of cervical cancers measured by TVES were recorded and compared with the pathological results. Interclass correlation coefficient (ICC) was used to analyze the reproducibility. RESULTS: Strain ratio of malignant lesions were much higher than that of the benign lesions (8.19±5.66 vs. 2.81±2.24, P<0.01). Area under the curve (AUC) was 0.905 with a 95% CI (0.835-0.976). The best cut-off point of strain ratio value was 4.53. Specificity and sensitivity for the best cut-off point were 0.788 and 0.897, respectively. Mean depth of the 56 malignant lesions was 17.8±7.4mm measured by TVES (range 5.4-43.1mm) and 11.5±8.8mm measured by pathological samples (range 3.7-38.4mm). ICC of the 2 methods were 0.87 (95% CI 0.863-0.947) and 0.931 (95% CI 0.902-0.952) for the 2 observers. CONCLUSIONS: TVES was a useful technique in confirming the diagnoses of cervical cancer and in estimating the infiltrating region. When the strain ratio of a cervical lesion was higher than 4.53, it is confidential to be diagnosed as malignant. |

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.
