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.

Why would 41% of women with dense breasts avoid supplemental breast MRIs?

More than 41 percent of women with dense breasts will choose to forgo supplemental breast MRI after receiving a negative mammography screening, according to a study recently published in Clinical Radiology.

Cardiac MRI effective in diagnosing rare 'broken heart syndrome'

Australian researchers found cardiac MRI an accurate method of diagnosing mid-cavity variant Takotsubo cardiomyopathy (TCM)—a rare acute coronary syndrome also known as "broken heart syndrome"—in a case study published in Current Problems in Diagnostic Radiology.

Research finds talking with radiographer calms patients before MRI

Nerves before an MRI are normal—up to 37 percent of patients report either moderate or high levels of anxiety leading up to an exam—and this apprehension can have physical consequences that render an entire scanning experience useless, first author J.R. Tugwell and colleagues wrote in Radiography this month.

Radiomics differentiates luminal A breast cancer, benign lesions from MRI dataset

Researchers have found that quantitative radiomics can better distinguish between benign lesions and luminal A breast cancers than using maximum linear size alone, according to a study published May 10 in Academic Radiology.

Extracting radiomic features from MR images helps with breast lesion classification

Extracting radiomic features from MR images can help radiologists distinguish between benign breast lesions and luminal A breast cancers, according to a new study published by Academic Radiology.

Canadian particle accelerator produces Tc-99m isotopes

A team at the University of Alberta in Canada has devised a method utilizing a cyclotron particle accelerator to produce the radioactive tracer technetium-99m—the parent of Molybdenum-99. It may be able to produce enough radioactive isotope for the entire province, CBC.ca reports.

Machine learning objectively contours CT scans, saves time for radiation oncologists

Contouring is an instrumental process for radiation oncologists and their patients—but the method is highly subjective. Researchers found their deep neural network algorithm could result in massive time savings for providers.

No-shows in radiology most common for mammogram, ultrasound appointments

Around 3 percent of radiology patients miss pre-scheduled imaging appointments at any given time, researchers out of the University of Washington report in the Journal of the American College of Radiology—but mammography and ultrasound see no-show rates more than double that.
