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.

fMRI shows how music activates brain regions untouched by Alzheimer's

Using functional MRI (fMRI), researchers at the University of Utah Health found that music activates regions of the brain spared from memory loss caused by Alzheimer's disease.

Brain tumor biomarkers could help eliminate surgical biopsies

A team from Washington University in St. Louis developed a proof-of-concept technique to detect tumor biomarkers via a blood test using noninvasive focused ultrasound. The method could potentially eliminate surgical biopsies, according to a study in Scientific Reports.

MRI may expand tPA treatment to include unwitnessed stroke patients

Recent study findings from Massachusetts General Hospital (MGH) researchers may increase the number of stroke patients who can safely be treated with tissue plasminogen activator (tPA), or alteplase, according to an MGH release.

'Erasable' MRI contrast agents could simplify diagnostic imaging, disease detection

Researchers at CalTech are developing "erasable" contrast agents that can "blink off" on command during an MRI to reveal their exact location inside the body, according to a press release from the California Institute of Technology.

First-ever rhino CT scan may be life-saving

A sinus infection is no fun for most—but when 7-year-old Layla, a 2,300-pound black rhinoceros, was suffering from the condition, veterinarians needed a better understanding of her skull to guide treatment.

Image reconstruction algorithm, MRI-derived heart strain values can aid prognosis in amyloidosis patients

Recent research found strain parameters taken from a cine MRI-based deformable registration algorithm (DRA) can determine the severity of amyloid buildup in the heart and may provide prognostic information on patients with light-chain (AL) amyloidosis.

False-positives increase follow-up screening participation

Patients who receive a false-positive breast or prostate cancer screening are more likely to continually participate in follow-up screenings, according to a study published in Cancer.

RBMA President Peter Moffatt discusses declining reimbursement rates, recruiting challenges and the role of artificial intelligence in transforming the industry.

Deepak Bhatt, MD, director of the Mount Sinai Fuster Heart Hospital and principal investigator of the TRANSFORM trial, explains an emerging technique for cardiac screening: combining coronary CT angiography with artificial intelligence for plaque analysis to create an approach similar to mammography.

A total of 16 cardiology practices from 12 states settled with the DOJ to resolve allegations they overbilled Medicare for imaging agents used to diagnose cardiovascular disease.
