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.

Lung Association finds low-dose CT screenings underused but cancer survival improving

More than 16% of eligible individuals get screened for lung cancer in Massachusetts. Only 1% do so in California. The national average is unfortunately closer to the latter extreme, at 5.8%.

FDA expands indications for neuroimaging radiotracer

An established radiopharmaceutical can now be applied with the FDA’s blessing when symptoms of cognitive decline point to the second most common form of degenerative dementia (after only Alzheimer’s disease).  

FDA greenlights intracranial hemorrhage AI

RapidAI has been cleared for U.S. marketing of updated AI-outfitted software that quickly detects or rules out acute brain hemorrhage on unenhanced CT.

Lyme disease neuroimaging uncovers compensatory brain repair

Lyme disease patients treated for “brain fog” may develop compensatory alterations in white matter that show up on MRI and correspond—unexpectedly—with slow but sound cognitive performance.

James Udelson, MD, from Tufts and an investiogator in the PRECISE trial, explains how FFR-CT combined with coronary CT outperformed the standard of care in patients with stable chest pain, or low-risk patients with suspected coronary involvement.

VIDEO: PRECISE trial shows cardiac CT with FFR-CT significantly improves patient outcomes

James Udelson, MD, an investigator involved with the PRECISE trial, explained how patient outcomes were improved by 70% from the current standard of care.

Neuroimaging recedes behind other cost compilers in stroke care

Contrary to older research that showed neuroimaging emerging as the single most dominating cost contributor in ischemic stroke care for older Americans, a new study shows treatment and other line items account for bigger slices of the bill.

Pandemic anxiety in mothers-to-be shows up in fetal neuroimaging

Pregnant women who felt stressed by healthcare disruptions caused by the COVID-19 pandemic radiated the unease to their developing offspring. The effects were observable on fetal MRI of both brainstem structure and functional activity.

MRI system advances include helium-free MRI systems (left is Philips version of this system), and compressed sensing (right, GE's version of this technology), which can greatly reduce scan times. Both technologies were mentioned in an overview by Signet Research of new tech that will be at RSNA 2022.

VIDEO: Overview of MRI market and technology trends

Bhvita Jani, research manager, Signify Research, explains some key trends and technology advances in the magnetic resonance imaging (MRI) market leading into the Radiological Society of North America (RSNA) 2022 meeting.

The ACR hopes these changes, including the addition of diagnostic performance feedback, will help reduce the number of patients with incidental nodules lost to follow-up each year.

And it can do so with almost 100% accuracy as a first reader, according to a new large-scale analysis.

The patient, who was being cared for in the ICU, was not accompanied or monitored by nursing staff during his exam, despite being sedated.
