The investigator has conducted extensive research on ICAD by transcranial Doppler ultrasound, CT angiography and perfusion studies, magnetic resonance imaging (MRI) and digital subtraction angiography (DSA) respectively. Currently, the investigator applied 3-dimensional rotational angiogram (3DRA), a selective intra-arterial catheter-based imaging technique that had a superior spatial resolution compared with CT, MRI or DSA in depicting minute (<3mm) angio-architecture. Through 3DRA, the investigator could appreciate the ICAD patho-anatomy from a near-infinite number of planes, analyzing the stroke mechanisms and morphological changes with much improved precision. A neuro-radiologist and a stroke neurologist blind to time sequence will measure the geometric parameters and the luminal narrowing by WASID method.
