Little is known concerning the corresponding diagnostic value of fluid-attenuated inversion recovery (FLAIR), echo-planar T2* susceptibility-weighted imaging (T2*SW) or diffusion-weighted images (DWI).\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>\n              <jats:italic>Methods\u2014<\/jats:italic>\n            <\/jats:bold>\n            We performed a retrospective analysis of 114 MRI examinations from 39 patients with CVT using a structured assessment. The time course of sensitivity in the detection of clot (n=166 clots) was analyzed for different MR sequences using a multilevel logistic model. The sensitivity of different MR sequences for diagnosis of cortical venous thrombosis was tested separately (n=38 clots).\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>\n              <jats:italic>Results\u2014<\/jats:italic>\n            <\/jats:bold>\n            The sensitivity of T2*SW and T1-weighted spin echo image (T1SE) sequences to detect clot in the sinuses or veins was estimated at 90% and 71% between day 1 and day 3, which was much higher than that of T2SE, FLAIR or DWI during the first week of clinical onset. The sensitivity of T2*SW was stable in the first week. After this period, the sensitivity of T2*SW decreased less than that of T1SE. Thrombosed cortical veins, even in the absence of visible occlusion on magnetic resonance venography, were detected more frequently with T2*SW (97%) and T1SE (78%) than with FLAIR or DWI (&lt;40%).\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>\n              <jats:italic>Conclusions\u2014<\/jats:italic>\n            <\/jats:bold>\n            T2*SW imaging appears to be of additional diagnostic value in CVT. The T2*SW sequence may be particularly useful during the acute phase of CVT when the sensitivity of the other sequences is incomplete and for the diagnosis of isolated cortical venous thrombosis.\n          <\/jats:p>","DOI":"10.1161\/01.str.0000206282.85610.ae","type":"journal-article","created":{"date-parts":[[2006,2,17]],"date-time":"2006-02-17T01:54:26Z","timestamp":1140141266000},"page":"991-995","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":206,"title":["MRI of Clot in Cerebral Venous Thrombosis"],"prefix":"10.1161","volume":"37","author":[{"given":"Ahmed","family":"Idbaih","sequence":"first","affiliation":[{"name":"From the Department of Neurology (A.I., I.C., M.-G.B., H.C.) and Department of Neuroradiology (M.B.), Hopital Lariboisie\u0300re, Paris, France; the Department of Biostatistics (R.P.), Ho\u0302pital Saint-Louis, Paris, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Monique","family":"Boukobza","sequence":"additional","affiliation":[{"name":"From the Department of Neurology (A.I., I.C., M.-G.B., H.C.) and Department of Neuroradiology (M.B.), Hopital Lariboisie\u0300re, Paris, France; the Department of Biostatistics (R.P.), Ho\u0302pital Saint-Louis, Paris, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isabelle","family":"Crassard","sequence":"additional","affiliation":[{"name":"From the Department of Neurology (A.I., I.C., M.-G.B., H.C.) and Department of Neuroradiology (M.B.), Hopital Lariboisie\u0300re, Paris, France; the Department of Biostatistics (R.P.), Ho\u0302pital Saint-Louis, Paris, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raphae\u0308l","family":"Porcher","sequence":"additional","affiliation":[{"name":"From the Department of Neurology (A.I., I.C., M.-G.B., H.C.) and Department of Neuroradiology (M.B.), Hopital Lariboisie\u0300re, Paris, France; the Department of Biostatistics (R.P.), Ho\u0302pital Saint-Louis, Paris, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marie-Germaine","family":"Bousser","sequence":"additional","affiliation":[{"name":"From the Department of Neurology (A.I., I.C., M.-G.B., H.C.) and Department of Neuroradiology (M.B.), Hopital Lariboisie\u0300re, Paris, France; the Department of Biostatistics (R.P.), Ho\u0302pital Saint-Louis, Paris, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hugues","family":"Chabriat","sequence":"additional","affiliation":[{"name":"From the Department of Neurology (A.I., I.C., M.-G.B., H.C.) and Department of Neuroradiology (M.B.), Hopital Lariboisie\u0300re, Paris, France; the Department of Biostatistics (R.P.), Ho\u0302pital Saint-Louis, Paris, France."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_1_1_2","doi-asserted-by":"publisher","DOI":"10.1161\/str.16.2.3975957"},{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0733-8619(18)30235-4"},{"key":"e_1_3_1_3_2","doi-asserted-by":"crossref","unstructured":"Bousser MG Russell R.
