So far, the major role of the neuroradiology in the management of TBM has been restricted to diagnosis and follow-up of the complications. This study aimed to establish the use of advanced magnetic resonance imaging (MRI) techniques in the early detection of sequelae of TBM like vasculitis and hydrocephalous.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods:<\/jats:title>\n                    <jats:p>In this prospective observational study, 30 patients of TBM were recruited during 1 year at a tertiary care health center of northern India and their serial MRI brain was done.

No significant difference was found between the mean, mean diffusivity (MD), and mean fractional anisotropy (FA) in frontal white matter, basal ganglia, thalamus, pons of cases and controls. A significant difference was seen between mean cerebral blood flow (CBF) in the region of basal ganglia of cases and controls (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.05). No significant difference was seen between mean CBF in frontal white matter, thalamus of cases and controls. Diffusion tensor imaging parameters, MD, and FA were abnormal in the region of infarcts (basal ganglia) in three patients in the first scan, the parameters normalized in one patient (late subacute to chronic infarct in the first scan), and they remained abnormal in two patients.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Advanced MRI techniques (magnetization transfer imaging) is helpful in visualizing hyperintense thickened meninges in basal cisterns and Sylvian fissures on pre-contrast imaging, and in identifying reduced CBF in the region of basal ganglia.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/abr.abr_222_19","type":"journal-article","created":{"date-parts":[[2020,6,22]],"date-time":"2020-06-22T01:11:36Z","timestamp":1592788296000},"update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":4,"title":["Advanced Magnetic Resonance Imaging Techniques in Tuberculous Meningitis"],"prefix":"10.4103","volume":"9","author":[{"given":"Sukriti","family":"Kumar","sequence":"first","affiliation":[{"name":"From the Department of Radiodiagnosis, KGMU, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manish","family":"Gutch","sequence":"additional","affiliation":[{"name":"Department of Endocrinology, Dr. RMLIMS, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2020,5,29]]},"reference":[{"key":"R1-20250805","doi-asserted-by":"crossref","first-page":"938","DOI":"10.1016\/S0140-6736(06)68384-0","article-title":"Global epidemiology of tuberculosis","volume":"367","author":"Dye","year":"2006","journal-title":"Lancet"},{"key":"R2-20250805","doi-asserted-by":"crossref","first-page":"205","DOI":"10.1093\/oxfordjournals.aje.a112675","article-title":"Extrapulmonary tuberculosis in the United States","volume":"109","author":"Farer","year":"1979","journal-title":"Am J Epidemiol"},{"key":"R3-20250805","doi-asserted-by":"crossref","first-page":"668","DOI":"10.1056\/NEJM199203053261004","article-title":"Tuberculous meningitis in patients infected with the human immunodeficiency virus","volume":"326","author":"Berenguer","year":"1992","journal-title":"N Engl J Med"},{"key":"R4-20250805","doi-asserted-by":"crossref","first-page":"1194","DOI":"10.1093\/infdis\/173.5.1194","article-title":"Multinucleated giant cell formation of swine microglia induced by Mycobacterium bovis","volume":"173","author":"Peterson","year":"1996","journal-title":"J Infect Dis"},{"key":"R5-20250805","doi-asserted-by":"crossref","first-page":"29","DOI":"10.1016\/0002-9343(85)90542-X","article-title":"Mycobacterial meningitis.
