Journal ArticleDOI
Large artery ischaemic stroke in severe acute respiratory syndrome (SARS).
T. Umapathi,Ai Ching Kor,Narayanaswamy Venketasubramanian,C. C. Tchoyoson Lim,Boon Chuan Pang,Tseng Tsai Yeo,Cheng Chuan Lee,Poh Lian Lim,Poh Lian Lim,Kuperan Ponnudurai,Khoon Leong Chuah,Puay Hoon Tan,Dessmon Y.H. Tai,Sze Peng Brenda Ang +13 more
TL;DR: It is believed that increased vigilance against stroke and other thrombotic complications among critically-ill SARS patients in future outbreaks is needed, especially if treatment such as intravenous immunoglobulin, that increases pro-thrombosis tendency, is contemplated.
Journal ArticleDOI
Differential diagnosis for bilateral abnormalities of the basal ganglia and thalamus.
TL;DR: In this paper, the authors used confirmatory neuroimaging investigations, especially diffusion-weighted imaging, MR angiography, MR venography, and MR spectroscopy during the same examination, to help improve characterization of these abnormalities and help narrow the differential diagnosis.
Journal ArticleDOI
Territorial arterial spin labeling in the assessment of collateral circulation: comparison with digital subtraction angiography.
TL;DR: Combined territorial ASL and MR angiography against DSA provided radiological information comparable to DSA on collateral flow, with the advantage that it could be performed during routine MRI studies.
Journal ArticleDOI
Comparison of magnetic resonance spectroscopy and perfusion-weighted imaging in presurgical grading of oligodendroglial tumors.
Maosheng Xu,Siew Ju See,Wai Hoe Ng,Earnest Arul,Michael Back,Tseng Tsai Yeo,C. C. Tchoyoson Lim +6 more
TL;DR: MRSI measurements are more accurate than perfusion-weighted magnetic resonance imaging or conventional contrast enhancement in differentiating oligodendroglial tumor grade in these inherently vascular tumors and may be better than measures of neovascularity in presurgical grading.
Journal Article

C. C. Tchoyoson Lim,Yih Yian Sitoh,Francis Hui,Kim En Lee,Brenda Ang,Erle C.H. Lim,Winston Eng Hoe Lim,Helen M. L. Oh,Paul A. Tambyah,Jill S. L. Wong,Chai Beng Tan,Thomas S. G. Chee +11 more
TL;DR: The brain MR findings in patients infected with the newly discovered Nipah paramyxovirus are different from those of patients with Japanese encephalitis, a striking difference in the appearance and distribution of lesions is useful in differentiating these diseases in a zoonotic epidemic.
