About

Primary purpose of the study is to show wether computed tomography with photon counting detector has a diagnostic image quality as good as, or better than classic computed tomography in investigations concerning stroke work-up.

Full description

Images of the skull/brain at the level of the inner ear/temporal bone and the level of nucleus lentiformis will be compared with the same patients routine brain done in TIA (transient ischemic attack)/stroke workup.

Images of the carotid plaque will be compared with the same patients routine CT-angiogram done in TIA/stroke workup.

Enrollment: 10 estimated patients

Sex: All

Ages: 50+ years old
