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.

Deep learning model accurately detects COVID-19 on chest X-ray images

Is it pneumonia or COVID-19? With the help of artificial intelligence, a chest X-ray can reveal the answer.

Deep learning algorithm predicts emphysema mortality

Authors of the study noted that using the algorithm eliminates the issue of subjectivity and time-consuming visual assessments of emphysema.

A comparison of standard 2D mammography (right) and digital breast tomosynthesis (DBT), or 3D mammography (left). The DBT creates a data set of 1 mm slices that the radiologist can look through to see more detail in suspect areas and determine if it dense breast tissue is masking a tumor.

DBT not the superior modality for assessing BI-RADS 4 breast lesions

Assessing more than 11,000 patients with lesions designated as BI-RADS 4, radiologists using digital breast tomosynthesis found no significant diagnostic advantages over standard 2D mammography.

Alan Matsumoto explains gadolinium as substitute for iodine contrast during shortage

VIDEO: Gadolinium being substituted for iodine contrast in some procedures due to shortage

Alan H. Matsumoto, MD, chair of the department of radiology at the University of Virginia, vice chair of the American College of Radiology (ACR) Board of Chancellors, and chairman of the ACR Commission on Interventional and Cardiovascular Radiology, explains that the iodine contrast shortage has led to use of MRI gadolinium contrast agents in some cases.

Measurements from functional MRI scans offer non-invasive boost in liver disease assessment

By using a combination of functional liver imaging scores (FLIS) derived from gadoxetic acid (GA)-enhanced MRI and splenic diameter measured on MRI, the experts were able to non-invasively assess liver impairment.

VIDEO: How the iodine contrast shortage is impacting interventional cath labs

Kirk Garratt, MD, medical director of the Center for Heart and Vascular Health, ChristianaCare, and a past president of SCAI, explains what this shortage means for interventional cardiologists.

Imaging features were also examined as predictive time to resolution factors, with cortical thickness of the nodes being of particular interest.

Addressing contrast media shortage in the short, mid and long term

“We need to commit to changing the supply chain so that a single event in a faraway country does not put us in this predicament again," experts wrote in a new special report shared by Radiology.
