Imaging techniques reliably predict treatment outcomes for TB patients

Two medical imaging techniques, called positron emission tomography and computed tomography, could be used in combination as a biomarker to predict the effectiveness of antibiotic drug regimens being tested to treat tuberculosis patients, according to researchers. With multidrug-resistant tuberculosis and extensively drug-resistant tuberculosis on the rise worldwide, new biomarkers are needed to determine whether a particular TB drug regimen is effective.
