Artificial intelligence (AI) algorithms can be trained to recognise tuberculosis-related abnormalities on chest radiographs. Various AI are available commercially, yet there is little impartial evidence how their performance compares with each other and radiologists. We aimed evaluate five commercial for triaging tuberculosis using a large dataset that had not previously been used train any algorithms.Individuals aged 15 years or older presenting referred three screening centres in Dhaka,...

Background GeneXpert MTB/RIF (Xpert) and Genotype MTBDRplus (DRplus) are two World Health Organization (WHO) endorsed probe based molecular drug susceptibility testing (DST) methods for rapid diagnosis of resistant tuberculosis. Both target the same 81 bp Rifampicin Resistance Determining Region (RRDR) bacterial RNA polymerase β subunit (rpoB) detection (RIF) resistance associated mutations using DNA probes. So there is a correspondence probes each other expected similarity binding. Methods...
