Medical Imaging

Physicians utilize medical imaging to see inside the body to diagnose and treat patients. This includes computed tomography (CT), magnetic resonance imaging (MRI), X-ray, ultrasound, fluoroscopy, angiography,  and the nuclear imaging modalities of PET and SPECT.

Major teaching hospital finds half its on-call abdominal ultrasounds call utilization into question

The investigators encourage radiologists to consider the numbers and take steps to “reinforce their gatekeeper function” to help cut ultrasound overutilization.

Lung cancer risk increases with emphysema severity

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.

Deep learning and rads comprise an ‘efficient pipeline’ for detecting, classifying thyroid nodules

Competing to classify thyroid nodules on ultrasound images as either malignant or benign, three deep learning models have essentially drawn a tie with four radiologists.

DL networks augment radiologist performance for thyroid cancer detection

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.

New x-ray technique for checking tube placement cuts radiation dose 80%

Radiologists have developed an abdominal x-ray protocol that quantifies patient “thickness” to yield images of high quality while reducing radiation dose by 80%.

Study urges radiologists to report CAC findings on all chest CTs, regardless of clinical indication

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.
