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.

Machine learning model quickly and accurately predicts outcomes for TBI patients

The model combines clinical data with imaging from head CT scans in individuals with severe traumatic brain injuries to quickly predict 6-month outcomes.

Disparities evident as CT stroke imaging rises sharply over 7-year period

Utilization of head CT perfusion (CTP) for imaging stroke patients spiked 428% between 2012 and 2019. Curiously, the uptrend was associated with higher mortality up to a year after discharge.

New MRI technique helps physicians ID multiple sclerosis lesions

By superimposing images of tiny veins in the brain over conventional MRI modules, physicians can identify the distinguishing "central vein sign."

Metastatic breast cancer survival rates are up in Medicaid expansion states

A JAMA Oncology study found a decrease in two-year mortality rates between 2010 and 2015, attributing the findings to a 2014 Medicaid expansion.

The American Society of Nuclear Cardiology (ASNC) is asking Congress to repeal the appropriate use software provision mandate, which physicians say is an obstacle to efficient care.

Randall Thompson, MD, immediate past president of the American Society of Nuclear Cardiology (ASNC), explains the current ASNC lobbying efforts.

CT scans find prone position increases lung recruitment for COVID-19 patients

Using CT scans and EIT, researchers from an Italian hospital shed light on the specific benefits of the prone position for intubated COVID-19 patients.

Maternal social disadvantages linked with reduction in baby brain volumes at birth

Economic hardship was associated with smaller global brain volumes, while maternal psychosocial stress did not reveal any significant impacts.

O-RADS externally validated for differentiating between benign and malignant ovarian lesions

In addition to O-RADS external validation, experts also sought to determine if incorporating acoustic shadowing as a benign finding would improve diagnostic performance.
