Johannes Kaesmacher, MD, and Siemens Healthineers

Siemens Healthineers and Cercare Medical will collaborate globally to accelerate the adoption of conebeam CT (CBCT) perfusion imaging in acute stroke care.

The effort combines Cercare Medical's Neurosuite -- an automated perfusion analysis platform for CT, MRI, and CBCT -- with Siemens’ Syngo DynaCT Multiphase, a 3D acquisition protocol supporting up to 10 CBCT angiography phases. Together, the tools enable perfusion and metabolic imaging directly in the angiography suite, which reduces the need to transfer stroke patients to a separate imaging room during interventions, according to an announcement from the companies.

The platform supports assessment of tissue viability during and after thrombectomy, including detection of distal occlusions and microvascular disturbances, the companies said.

Exemplary cases from the ESCAPE-MeVO trial illustrating good, moderate, and poor collateral status at baseline multiphase CT angiography (CTA). (A) Sagittal image shows a left anterior middle cerebral artery medium-vessel occlusion (MeVO) with a calcified thrombus (arrow). (B–D) Axial images show the (B) arterial, (C) peak venous, and (D) delayed venous phases of the baseline multiphase CTA examination. The affected brain parenchyma is highlighted by the dashed outline. The collateral status is good, with early filling of more than 50% of the leptomeningeal collaterals compared with the contralateral side in the arterial phase (B), and there is no delayed washout in the peak venous (C) or delayed venous phase (D). (E) Sagittal image shows a left anterior middle cerebral artery MeVO (arrow). (F–H) Axial images show the (F) arterial, (G) peak venous, and (H) delayed venous phases of the baseline multiphase CTA examination. The affected brain parenchyma is highlighted by the dashed outline. The collateral status is moderate (more than 25% but less than 50% filling of the leptomeningeal collaterals in the affected territory compared with the contralateral side) on the arterial (F) and peak venous (G) phase, and there is delayed washout in the late venous phase (H). (I) Sagittal image shows a posterior dominant middle cerebral artery MeVO (arrow). (J–L) Axial images show the (J) arterial, (K) peak venous, and (L) delayed venous phases of the baseline multiphase CTA examination. The affected brain parenchyma is highlighted by the dashed outline. The collateral status is poor, with almost no collateral filling.

Case example of a false-negative AI result. An 85-year-old female presented to the emergency department with dyspnea. Axial 0.625-mm from CT pulmonary angiography examination with contrast (CTPA) images demonstrate a thin, linear right-sided filling defect extending from the right interlobar pulmonary artery (A and B, red arrows) into the right middle lobar artery (B, yellow arrow), consistent with acute pulmonary embolism (PE). The finding was described in the radiology report; however, the AI result was negative for PE. Adjudication was consistent with acute PE.
