説明
We read Schindlbeck et al’s1 article on the predictability of contrast extravasation and hematoma expansion through the use of dynamic contrast-enhanced T1 magnetic resonance imaging (MRI) with great interest. Previously, we explored prediction of hematoma enlargement with observations of contrast fluid leakage using both contrast MRI2 and computed tomographic angiography.3 During our research 18 years ago, we2 used a 0.2-T MRI. However, MRI machines have progressed in the examination time. Schindlbeck et al1 used a 3-T MRI and MRI imaging time has decreased; MRI is becoming an appropriate scan for acute stroke patients with varying neurological findings. Compared with computed tomographic angiography, there is no exposure to radiation in contrast MRI, and the frequency of allergies to contrast fluid is low. It may be a safer, more detailed examination …
