 Valuation of spinal tuberculosis on 3 Tesla MRI AK study, POTS disease, a tubercular infection of spine was first described in 1779 by preservival POTS is the most common cause of non-promatic papillage in the world, the spinal involvement is usually a result of matrogenous spread of mycobacterium TV virus peritrary tract or intestine into the dense vasculature of cancerous bones or vertebral bodies, involvement of IBD which is also in loss of disk height and collapse of vertebral body result in sharp angulation called as kyphus. According to WHO in 2006, nearly 2 billion people about one third of world's population had tuberculosis. Spinal TB accounts for 2% of all TB cases, 15% of all cases of extra pulmonary TB and 50% of skeletal TB. The clinical presentation of TB spine is variable and in-situ is an onset. The most common symptom of all being low-pacted. Constitutional symptoms such as loss of weight, anorexia, low-grade fever and mildews are more commonly associated with pulmonary TB than with spinal TB. Play next day CT and MRI at the prime modalities to assess the POTS spine. There must be at least 30% destruction of bone mineral loss is needed to show the radial nuisance your next day. CT is an excellent tool for delineating bony details. However, it is inferior to MR for early assessment of neural structures as well as soft tissue extension, so it is not preferred due to radiation exposure. MRI provides excellent details of neural as well as soft tissue extension in spinal TB, therefore beneficial for early diagnosis as well as planning management. Aim of the study is to study the role of 3 Tesla MRI in evaluation of spinal tuberculosis objectives to describe the pattern of occurrence of TB, a spinal TB on MRI, to evaluate the role of MRI in assessing the extent of disease and its correlation with the neurological status of patient of spinal TB. The study was done in the Department of Retrodiagnosant Imaging PT Metisherma PjMS Rotherk, 85 patients were taken irrespective of age and sex, who were clinically suspected to diagnose cases of TB. Inclusion criteria is all clinically suspected or diagnosed cases of spinal TB. Exclusion criteria is previously operated or completely treated patients of spinal TB, any metallic implants, claustrophobia and traumatic and degenerative cases. Parameters to be taken T1-weighted, sagittal and axial, T2-weighted, sagittal and axial images stir sagittal images and post contrast images. Results. The study was carried out on 85 patients out of which 49 were male and 36 were females, the mean age of subjects were 37.2 years, maximum number of patients were between age group of 20 to 30 years. The most common symptoms in this series were back it which was present in 73 out of 85 patients, 85 percent patient had constitutional symptoms, neurological involvement in the form of food pain was present in 32 patients, whereas paracels was present in 23 patients. ESR was raised in 82 out of 85 patients, Montu was done in all 85 patients, found to be positive in 75 of them. Chest X-ray was taken in all patients, PFU, it revealed associated pulmonary TB in 27 patients. Plain X-ray finding were abnormally in 72 out of 85 patients, involvement of body was present in 66 out of 85 patients. Typical picture of tuberculosis spined that is paradiscule was present in 18 out of 85 patients. Osteitis was seen as T1 hyperintensity and T2 hyperintensity. On T1 images 74 out of 85 patients showed hyperintensity signal and 80 percent patients showed hyperintensity signal in T2-weighted images. Stur sequence, stir sequence, 87 patient shows hyperintensity signal intensity, 53 out of 80 patients showed for peripheral in the accident. Maximum number of vertebral body, vertebrae involved in a single patient were 14, minimum work, vertebrae in a single patient. On MR imaging, average number of vertebrae involvement was 3, lumbar spine was the most common site of involvement seen in presence 30, 36 out of 85 patients showed involvement of lumbar spine. Second most common site was dorsal spine with involvement of 27 out of 85 patients. Least common site was cervical dorsal followed by sacral. 47 out of 85 showed epidural collection, 22 out of 85 showed changes in signal intensity of spinal cord. Case 1, 25 year old female with chronic fatigue, low grade fever and bowel and bladder weakness. First image is the frontal radiograph of sacral spine showing blurring of flumbo-sacral region. Second image is the T2-weighted sag showing large pre-vertebral and anterior epidural collection. Second image, 42 year old male with chronic low backache with acute onset weakness in bilateral volume. First image is non-contiguous involvement of tubercular spine. Second image is the typical peripheral enhancement of collection with enhancement of involved vertebrae. Third case, 6 year old child with visible deformity of back and unable to fall. First image is the frontal radiograph showing kyphosoliotid deformity. Second image is the coronal T1-weighted showing peripheral enhancement of the paravirtebral collection. Discussion, the age group of patient range from 2 to 88 years with mean age of subject was 37.2 years. The study population showed slight male pre-dominance with 42.4% female and 57% male. Similar observation was seen in study by Bhatnagar et al and Sainan et al. In our study, most common presenting symptoms was chronic low backache seen in 73 patients. Yandrapati et al also reported backache as the most relevant important history further focused. 14 out of 25 at 26 showed sublesinitis spread of infection. Similar results were seen by Antonio Archie. In our study, contiguous pattern of infection in spread is the most common pattern seen in 79 patients. Similar results were reported by Anil et al and with 95% patient showing contiguous pattern of spread. In present study, common radiographic findings of spine were consistent with spine reverses were vertebral body hand plate erosion seen in 76.77%. Then the antitravir et al reported end plate destruction 43% cases. In present study, the most common site of involvement was lumbar spine followed by dorsal spine. Roth et al reported two most common site of involvement were dorsal and lumbus acral spine. In present study, 87.1% cases showed hyper intense signal on T1 weighted sequence. T2 hyper intensity is noted in 80% of effective vertebra with hyper intense signal on star sequence in 87.1 patients suggesting 80 meters changes due to inflammatory process. These observations comparable to a similar study by Batnaker et al revealed T1 hyper intense signal with hyper intense signal on T2 and star. In our study, epidural collection was seen in 47 patient cases, which was similar to observation by Arsing et al. Janakia et al observed epidural collection in 80% cases with similar finding in study by Anil R et al. Conclusion. Since MRI is noninvasive, highly sensitive and capable of multi-planar imaging, it should be considered as main imaging modality for suspected tuberculosis, spondylitis, intradural extramedular tuberculosis, tubercular erectoiditis, intramedular tuberculosis. The ability of MRI to detect tuberculosis spine earlier than other technique could reduce the bone destruction and deform again, hence need for surgical intervention.
