Join us as we count down to 2021 with a SANS question every day this month. Test your knowledge and learn something new each day as you participate. Questions will be posted to Twitter daily.
What is the most likely appearance of a chronic subdural hematoma on MRI (in terms of intensity)?
Hyper on T1, hypo on T2
Hypo on T1, hyper on T2
Hyper on both T1 and T2
Hypo on both T1 and T2
The correct answer is Hyper on both T1 and T2.
Typically, a chronic subdural hematoma is hyperintense on both T1 and T2 weighted images, but about 30% of them may be either isointense or hypointense on T1 weighted images.
