A Retrospective, Multicenter, Controlled Clinical Trail: to Evaluate the Clinical Efficiency of Intracranial Aneurysm Assistive Software in the Morphological Measurement

March 27, 2023 updated by: Wang Shuo, Beijing Tiantan Hospital
the goal of this clinical trail is to evaluate the clinical efficiency of intracranial aneurysm assistive software in the morphological measurement. The trail is designed as retrospective, multicenter, controlled clinical trail. Collecting probable cases images retrospectively according to inclusion criteria and exclusion criteria strictly. Controlling bias strictly, to make sure the measurement of intracranial aneurysm assistive software is evaluated reliably and precisely. In our trail, six physicions were recruited, containing three neuroradiologists, two radiologists and a residents. Software-assistant planning controls against no software-assisant planning，which aims to evaluate the improvement of morphological measurement efficiency of physicians.
