Imaging software enables label-free CT imaging, improves lung diagnosis
Imaging showing close similarities between areas of lung function obtained on same patient with CTFI and Spect. A single-photon emission computerised tomography (Spect) scan uses a radioactive substance and a special camera to create lung images. CT-derived functional imaging (CTFI) does not require inhalation of special gas or injection of contrast. Image: Corewell Health
The CT-Derived Functional Imaging (CTFI) technique is a computed-tomography software program that uses the Integrated Jacobian Formulation to quickly calculate major changes in lung volume as a patient breathes in and out – without contrast dye
