In a recent interview, Takeshi Tsuda, M.D., discussed new study findings that show the viability of integrated wall stress as a key diagnostic marker for detecting preclinical cardiomyopathy in patients with Duchenne muscular dystrophy.
For myocardial extracellular volume quantification, single-phase and dual-phase photon-counting CT provided over 20 percent higher correlation with cardiac MRI in contrast to dual-phase energy-integrating detector CT, according to new research findings.
In a recent interview, Zeeshan Shah, M.D., discussed the challenges of addressing rising breast imaging volume amid the radiologist shortage, the potential of emerging AI solutions for bolstering efficient triage and an increasing incidence of breast cancer presentations in younger patients.
Offering the capability to convert a non-contrast chest CT into quantitative ventilation perfusion mapping, use of the CT:VQ software allows for additional Category III CPT reimbursement beyond the chest CT.
While the AI software offered nearly equivalent negative predictive value (NPV) to radiologist interpretation of digital mammograms and digital breast tomosynthesis (DBT) images, researchers noted that AI had significantly higher recall rates and false-positive results in patients with intermediate risk.
