Researchers analyzed a total of 21 studies that included more than 107,000 patients who had undergone CT assessments to examine associations between emphysema and lung cancer.
After being presented with more than 15,000 images, each DL network yielded results comparable to that of four seasoned radiologists, authors of a new EJR study said.
Although current guidelines recommend radiologists evaluate CAC on all non-gated, non-contrast chest CT scans, the authors of the study note that these guidelines are not consistently followed.
The results of a survey completed by more than 13,000 respondents who were eligible for the cancer screening revealed that less than 2% of eligible participants underwent CTC exams.
A new study found that while the absolute number of imaging studies performed in 2016 was twice the number of studies performed in 2004, the increase is attributable to a doubling in the number of active patients.
HeartFlow’s non-invasive cardiac computed tomography derived fractional flow reserve (FFR-CT) technology enables FFR values for the entire coronary tree of a patient using just a CT scan. This can show the significance of any coronary plaque lesions and if a patient needs to be sent to the cath lab for revascularization, or if they can be treated medically.
Experts have developed an artificial intelligence model that can estimate gestational age with accuracy that rivals that of formally trained sonographers completing fetal biometry scans.
