Hardly, any data are available regarding the number of clinical trials and their methodological quality that are conducted in allied fields of medicine. OBJECTIVE The present study was envisaged to assess methodological quality of trials in allied medical fields. MATERIALS AND METHODS(More)
Neural networks are a computational paradigm model of the human brain that has become popular in recent years. We have tried to address the problem of Gliomaby creating a more accurate classifier which can act as an expert assistant to medical practitioners. Brain stem gliomas are now recognized as a heterogenous group of tumors. In this paper, proposed a(More)
A b s t r a c t Most of the image retrieval systems are still incapable of providing retrieval result with high retrieval accuracy and less computational complexity. Image Retrieval technique to retrieve similar and relevant Computed Tomography (CT) images of lung from a large database of images. During the process of retrieval, a query image which contains(More)
Magnetic resonance (MR) images are a very useful tool to detect the tumor growth in brain but precise brain image segmentation is a difficult and time consuming process. Manual segmentation of brain tumors from MR images is a challenging and time consuming task. In this paper our approach has been discussed to detect the volume of brain tumor cells using(More)

INTRODUCTION Pilot studies play a pivotal role in deciding whether a main study can be undertaken thereby helping in appropriate framing of time, cost and study methods. However, they cannot be employed for testing a hypothesis and are underpowered in detecting clinically significant differences between the treatment arms. Literature from the west has shown(More)
Obtaining negative or contradicting results, whereas conducting a study has always been overlooked as inadequacies on the part of the researcher. Many-a-times, negative results are arrived at even after conducting the study with great care and effort. This cannot be considered, a flaw, always. Contradicting results may be arrived at because of various(More)
