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. 

alzheimer's disease dementia brain imaging

Machine learning winnows memory-care cohort to only the most appropriate nuc-med patients

An AI-aided way has emerged to confidently select dementia patients who are likely to benefit from amyloid-PET imaging while appropriately de-selecting patients for whom the costly exam would probably be unhelpful.  

PSMA PET/CT shows promise for spotting metastatic disease in patients with renal cell carcinoma

Up to 30% of patients have metastatic disease by the time they are initially diagnosed with renal cell carcinoma, making accurate staging a critical element of treatment planning. 

Investigation into patient's death after contrast injection begins

The man's wife told the court that he had undergone similar scans multiple times before and had never experienced any sort of adverse reaction. 

deep learning algorithm slashes radiation dose during neck CT scans

Deep learning denoising software can cut radiation exposure to 25% of conventional doses during neck CT

And the dose reduction can be achieved without sacrificing image quality, a new analysis shows.

the words "FDA recall" on a board

Dozens of injuries trigger FDA recall of over 50,000 implantable tissue marking devices

The Class I recall, which is the most serious recall the FDA issues, comes after numerous adverse events and complications linked to the radiographic markers were reported.

Machine learning helps experts identify ADHD biomarkers on MRI scans

Experts have identified numerous white matter features, in addition to changes in white matter tracts that occur over time, which they believe are more common among people with ADHD.

mammography mammogram breast cancer

Age, race and density status influence AI performance on mammogram reads

Although studies have shown AI to be effective as a support tool, several have also highlighted issues related to the potential for bias in algorithms that have not been trained on diverse datasets. 

time-delayed MRI phases improve brain tumor visualization

Using multiple MRI phases after contrast injection significantly improves visualization of brain tumors

Researchers are proposing making additional phases beyond the 10-minute mark mandatory when analyzing brain metastases.

These findings present additional evidence that invasive imaging tests are not necessarily more effective when it comes to evaluating patients for chest pain.

Unlike other UEA options, GE HealthCare's Optison does not contain polyethylene glycol. The FDA approved its use for adult patients back in 1997.

The new 1.5T MRI scanner includes a wide bore and key AI features designed to boost the patient experience.
