A practical protocol for shortening reconstruction time of volumetric data and imaging bilateral middle cerebral arteries for thrombectomy in acute ischemic stroke using an 80-row computed tomography scanner

摘要

Time-consuming reconstruction of volumetric data by area-detector-computed tomography (ADCT) scanning and narrow coverage of small-row ADCT may hinder volumetric scanning in acute stroke stage. To design a practical protocol of volumetric scanning for thrombectomy using an 80-row ADCT. An imaging protocol that focuses on the middle cerebral arteries by tilting the gantry of an 80-row ADCT with 0.5-mm-thick detectors can shorten the reconstruction time by 1.0-mm thickness scanning without subtraction. The reconstruction time of small volumetric data was 69 second. This practical protocol is applicable before thrombectomy in different stroke centres with narrow-coverage ADCT scanners.
