Context 1
... glucose was 7.8 mmol/L and other metabolic/electrolytes work-up were essentially normal. Non-contrast CT revealed a large region of encephalomalacia and gliosis of the left frontal and anterior temporal lobes (Figure 1). CT angiography showed focal occlusion of the anterior superior left M2 branch of the middle cerebral artery, abutting the anterior aspect of the aforementioned encephalomalacia (Figure 2). ...
Context 2
... arterial input and venous output functions placement and curves were good. Furthermore, cerebral blood volume (CBV) and cerebral blood flow (CBF) were decreased, and mean transit time (MTT) and time to drain (TTD) were increased ( Figure 3B-3E and Videos 1-4). These perfusion maps were noted to be widespread beyond the region of the suggested vascular occlusion seen on the CT angiography. ...
