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.

Company building novel portable stroke MR imaging platform seeks investors
New Zealand-based Wellumio in January announced its expansion into the U.S., laying the groundwork for local clinical trials to test its device.
Breast ultrasound finding may signal invasive cancer, research suggests
Though this finding is relatively uncommon, it is expected that the BI-RADS 6th edition ultrasound lexicon will include it as a feature associated with malignancy.
AI model nearly halves false positive rates for lung cancer CT screenings
Reducing false positives could decrease the frequency of unnecessary procedures, lower the associated costs and also ease patient anxiety concerning CT results.
A robot may soon be handling patients' ultrasounds in a Wisconsin health system
The machine will be operated remotely by a sonographer who has been trained to conduct remote ultrasound exams.
ED pivots to virtual radiology service, slashing CT turnaround times and lengths of stay
Syracuse, New York-based Upstate Medical University had previously relied on rad residents to handle initial reads, with attendings finalizing interpretation in the a.m.

Connectivity abnormalities observed on MRIs of insomnia patients

The authors explained that the increased connectivity observed in those with insomnia could lead to hypersensitivity to external stimulation, which might result in a state of hyperarousal.

Be prepared: IV contrast media shortage could last up to 8 weeks

All formulations and concentrations of GE Healthcare’s Omnipaque (iohexol) are expected to be in short supply until mid-June due to COVID lockdowns where the contrast is manufactured.

Radiologists should be aware of amyloid-related imaging abnormalities for patients taking Alzheimer's drug

Safety information for patients taking Aduhelm has been updated by the FDA to include the addition of two MRI scans during the first year of treatment.

A dedicated Cardiac MRI scanner. The presence of myocardial fibrosis on cardiac MRI can help anticipate adverse arrhythmic events and may offer a way to improve patient selection for cardiac implantable electronic devices (CIEDs). This is a dedicated cardiac MRI system at Baylor Scott White.

Could cardiac MRI become the reference standard for diagnosing heart failure?

Cardiac MRI may offer a more accurate and less invasive method for diagnosing heart failure, a new study published in the European Heart Journal shows.

FDA clears spinal-tap test that could challenge PET in Alzheimer’s diagnostics

The FDA has approved a lab test for evaluating cognitively impaired adults who may be in the early stages of Alzheimer’s disease.

COVID-19 vaccine associated myocarditis on short-axis 1.5T MRI images of a 19-year-old man who presented with chest pain three days following the second dose of an mRNA COVID-19 vaccine.

New cardiac MRI analysis offers updated insight into long-term impact of vaccine-related myocarditis

Months after their initial myocarditis diagnosis, late gadolinium enhancement (LGE) was observed in 62% of patients on follow-up cardiac MRI.

Foot ultrasound bested foot MRI on pooled sensitivity while lagging on specificity

MRI beats ultrasound at grading common foot injury, but tables turn for up-or-down diagnostics

Injuries of the plantar plate—the cluster of ligaments underneath the four smaller “knuckles” of the toes—are better assessed with MRI than with ultrasound scans.

Cardiac implantable electronic devices can be safely reprogrammed to MRI-safe mode via remote operator

In 209 study participants, the remote reprogramming resulted in a successful, event-free MRI scan for every patient.
