Background: Intrinsic differences between magnetic susceptibility of tissues can be used to generate a unique type of contrast in Magnetic Resonance Imaging (MRI), particularly to characterize tissues and improve the sensitivity for certain lesions, most notably hemorrhagic foci or calcification. Methods: A blinded retrospective review of all brain imaging studies done at our centre between March 2014 and February 2016. One of them reviewed the MR images with exclusion of SWI, while the other radiologist reviewed the entire set of images including SWI. Their findings were then compared to study the efficacy of SWI in better detection and characterization of lesions. Results: The study included 3710 patients with different brain lesions. SWI revealed positive lesions in at least 619 of these patients which were not picked up by the radiologist interpreting the conventional MRI protocol without SWI sequence. 21 patients with traumatic brain injury, 32 patients with cerebral microbleeds, 78 patients with brain tumors, 27 patients with venous malformations, 128 patients with intra-cranial calcifications, 277 patients with infarcts and 56 patients with extra-axial hemorrhage. Out of the 619 lesions, SWI played a significant role in lesion characterization in at least 198 patients which is about 5.33% of our total cohort of 3710 patients. Conclusion: SWI images are fast sequences requiring no more than a total scan time of about 3 minutes. Inclusion of this sequence as a part of brain pathology can play an important role in diagnosing different brain lesions without missing hemorrhagic lesions thus avoiding inappropriate therapeutic regimens with catastrophic results.

Background: Computed radiography (CR) has presently proven to be both efficient and cost effective as against conventional radiography. Cost benefit and cost effectiveness analysis of a newly installed computerized radiography system in comparison with Conventional radiography set-up in a tertiary care hospital.Methods: Costs incurred under major heads were calculated and compared for both Computerized and Conventional radiography systems. A brief survey regarding the overall clinician and patients response towards the newly installed CR system was carried out and results were calculated.Results: CR system proves to be highly efficient tool in the department of radiology to provide not only better quality images and faster means of image acquisition and archiving but also higher rates of satisfaction amongst radiology staff, clinicians and patients. Overall cost-effectiveness as well as the consumer satisfaction of the new technology is good as compared to conventional radiography. CR reduces repetition of images due to artifacts caused by dark room procedures and due to the provision of multiple images on a single film an average reduction in film expenditure. It reduces waiting period for patients and increases level of satisfaction in clinicians working in critical care dept. and A&E dept. due to early processing of urgent films.Conclusions: cost benefit analysis of CR over conventional radiography proved overall running costs are comparable to the conventional system with a breakeven point achievement in a couple of years since installation especially in a high turnover tertiary care health setup.

Introduction: Osteoarthritis is a disorder of the diarthrodial joint, a slow degenerative disease clinically characterized by pain, loss of range of motion. On x-ray seen as reduced joint space, formation of osteophytes and deformity. Manual therapy has been proved to be an effective treatment method in knee osteoarthritis (OA), but there is a need to investigate the effectiveness of MIMG manual therapy technique. There is limited evidence on the effect of MIMG protocol in knee OA. Aim: To find the effectiveness of MIMG protocol on pain and range of motion in knee osteoarthritis. Methodology- 38 subjects with the diagnosis of knee OA stage II and III on Kellegren Lawrence classification were recruited from Shree K.K. Sheth physiotherapy Centre, Rajkot, Gujarat. An interventional study was conducted on 38 subjects. Result: The outcome measures MIMG protocol is effective as conventional exercises in treating OA knee. Conclusion: MIMG can be suggested as one of the treatment protocol.
