Abstract

Objective: Diffusion tensor imaging may aid brain ischemia assessment but is more time consuming than conventional diffusion-weighted imaging (DWI). We compared 3-gradient direction DWI (3DWI) and 20-gradient direction DWI (20DWI) standard vendor protocols in a hospital-based prospective cohort of patients with transient ischemic attack (TIA) for lesion detection, lesion brightness, predictability of persisting infarction, and final infarct size.

Methods: We performed 3T-magnetic resonance imaging including diffusion and T2-fluid attenuated inversion recovery (FLAIR) within 72 h and 8 weeks after ictus. Qualitative lesion brightness was assessed by visual inspection. We measured lesion area and brightness with manual regions of interest and compared with homologous normal tissue.

Results: 117 patients with clinical TIA showed 78 DWI lesions. 2 lesions showed only on 3DWI. No lesions were uniquely 20DWI positive. 3DWI was visually brightest for 34 lesions. 12 lesions were brightest on 20DWI. The median 3DWI lesion area was larger for lesions equally bright, or brightest on 20DWI [median (IQR) 39 (18-95) versus 18 (10-34) mm2, P = 0.007]. 3DWI showed highest measured relative lesion signal intensity [median (IQR) 0.77 (0.48-1.17) versus 0.58 (0.34-0.81), P = 0.0006]. 3DWI relative lesion signal intensity was not correlated to absolute signal intensity, but 20DWI performed less well for low-contrast lesions. 3DWI lesion size was an independent predictor of persistent infarction. 3-gradient direction apparent diffusion coefficient areas were closest to 8-week FLAIR infarct size.

Conclusion: 3DWI detected more lesions and had higher relative lesion SI than 20DWI. 20DWI appeared blurred and did not add information.

Other contained patients with peripheral nerve compression (2), ophthalmological symptoms (2), trigeminal neuralgy (1), normal pressure hydrocephalus (1), hyperventilation (1), paresthesia secondary to anemia (1), peripheral extremity embolus (1), food poisoning (1), and secondary refusal (1). Reasons for lack of 20DWI/apparent diffusion coefficient (ADC) were technician error (3), incomplete examination due to restless patient (1), and technical error (1).

Figure 4
Comparison of relative lesion signal intensity (rSI) on 3-gradient direction DWI (3DWI) and 20DWI, N = 76. rSI is the normalized difference between signal intensities in lesions and contralateral homologous normal tissue, i, ipsilateral (lesion); c, contralateral. 3- and 20DWI sequences’ relative lesion signal intensity shows linear correlation. Best linear model fit has 0.7 incline implying that 3DWI has 30% higher relative lesion signal intensity than 20DWI. The dashed reference line has slope 1 indicating where rSI3 = rSI20.

Comparison of difference in relative signal intensity (%SI) to absolute signal intensities on 3-gradient direction DWI (3DWI)- and 20DWI, linear model regression lines with equations, N = 76. Difference in relative signal intensity is uniform for absolute 3DWI lesion signal intensities, but lower for low-signal lesions on 20DWI.

Distribution of lesions according to size measured on 3-gradient direction DWI (3DWI), and the two sequences’ difference in relative signal intensity (%SI), N = 76. The dashed reference line indicates where rSI3 = rSI20. Small lesions show highest variation in the two sequences’ difference in relative signal intensity (%SI), and predominantly highest relative signal intensity on 3DWI (i.e., %SI is negative).

Initial lesions’ median deviation from 8-week infarction area. This figure presents the median deviation between the initial lesion area on the respective sequences, and the area of the final infarction on 8-week magnetic resonance imaging. The smallest deviation (initial 3ADC) is significantly smaller than the deviation yielded by 3-gradient direction DWI (3DWI) or 20DWI. 20ADC and fluid attenuated inversion recovery (FLAIR) yielded deviations not significantly different from 3ADC.
