Abstract Objective: To investigate the distribution of deep medullary vein(DMV) in the transient ischemic attack(TIA) patients by using susceptibility-weighted imaging(SWI). Methods: MR images of 118 TIA patients and 32 healthy volunteers were double-blinded analyzed retrospectively. Two senior radiologists evaluated the image quality and DMVs symmetry at the same time, but evaluated DMV types respectively. DMVs showed identical areas in the lateral ventricles, amounts difference less than 5 and expanded similarly were defined symmetry. Kappa test were analyzed DMV types by two radiologists respectively. Contrasting superficial cerebral veins(SCV), DMV were defined in three types: type Ⅰ no visible DMVs; type Ⅱ DMVs<SCVs; type Ⅲ DMVs=SCVs. Thirteen volunteers of the control group had carried on the comparative study between two MR scanners(Siemens Verio 3.0T and GE Discover 750 3.0T). Results: The value of Kappa was 0.855 by two radiologists. By using Man-Whitney test, there was significant difference between DMV types of the TIA and the control groups(P=0.000, P
<0.05), there was also no significant difference between two groups of TIA(P=0.633, P>0.05). Fisher’s exact probabilities in 2×2 table was analyzed DMV symmetry of two groups(TIA and the health)(P=0.04, P<0.05). There was no difference in determining the DMV types between two MR scanners(χ2=0.5, P>0.05). Conclusions: DMV judgement of TIA patients had good consistency. DMV in the TIA could be asymmetric distribution and its diameter was much smaller than or close to SCV.
