Apollo is an AI-based solution designed to detect critical brain findings such as brain ischemia, hemorrhage, and tumors in real time throughmagnetic resonance imaging (MRI). In resource-constrained and primarily outpatient driven markets like India, AI tools such as Apollo can significantly impact the treatment turn around times for critical patients. In particular, stroke patients may be routed faster to treatment centers if they get access to outpatientradiological clinics [1, 2]. With this in mind, we aimed to assess Apollo’s impact in such an outpatientclinic in...

Apollo brain is a deep-learning based algorithm that was trained over 1500 manually annotated MRIs obtained from multiples sites across the world. Apollo detection tool uses diffusion weighte images (DWI), fluid attenuated inversion recovery (FLAIR), and T2* or susceptibility weighted imaging (SWI) sequences for the detection of infarcts, tumors, and hemorrhages. In this study, we focused on the ability of Apollo to detect acute and subacute ischemia in brain MRIs. Individuals included in this pilot study were consecutive patients over 4 weeks with a clinical...

A total of 43 patients were eligible for this study. Of these, n=16 showed acute non-lacunarinfarcts and n=27 showed either lacunar or chronic infarcts. Of the 16 non-lacunar acuteinfarcts, Apollo was able to flag 13 cases (diagnostic accuracy 81%). On average, all patientshad 9 sequences acquired. This number could be reduced to 4 with Apollo smart protocoling.The mean radiological reporting time for each patient was 4 hrs and 1 min, with 14% of casesreported after 6hrs. With Apollo’s flagging of potentially critical findings, the reporting...

Apollo stroke triage tool reduces significantly brain MRI acquisition times and reporting times ofacute cerebral infarctions.
