UltraCon: Microflow imaging on par with CEUS for guiding tumor ablation
AUSTIN -- Microflow imaging performs just as well as contrast-enhanced ultrasound (CEUS) for guiding tumor ablation and may be an economical alternative, according to research presented April 8 at UltraCon.
In her talk, Ziyue Hu, MD, from Sichuan Cancer Hospital in China highlighted findings showing that along with yielding comparable performance in treating thyroid nodules, microflow imaging in this area is less costly and invasive than CEUS.
“We found that in the microwave ablation procedure for thyroid nodules that … microflow imaging offers the advantages of reducing surgical expenses, which lessens the economic ...

French-led team unveils 11.7 tesla MRI scans of human brain
A research group based in Saclay, near Paris, has taken the wraps off what it claims are the world's first MRI scans of the human brain in vivo taken at a field strength of 11.7 tesla. President Emmanuel Macron has congratulated the researchers on social media.
"The first images surpassed our expectations, giving after just four minutes, mind-blowing brain images without any artifacts, with superb tissue contrast and resolution, which represents a volume equivalent to a few thousand neurons," Denis Le Bihan, PhD, founding director of the NeuroSpin research facility and founder of Iseult Project of the French Alternative E...

SPECT/CT algorithm predicts heart failure hospitalizations
This study represents the first evidence, to our knowledge, demonstrating that integrating SPECT MPI into an AI-based risk assessment algorithm significantly improves the prediction of hospitalizations due to [heart failure],” the group wrote. The research was published March 28 in the Journal of Nuclear Medicine.Heart failure is a major cause of morbidity and mortality in the United States and worldwide, with prevalence projected to increase by almost 50% from 2012 to 2030, the authors wrote. They noted that identifying patients who are at risk for heart failure exacerbation can open opportunities for prevention strateg...

PET/MRI may improve diagnosis of Cushing disease
PET/MRI could become the diagnostic method of choice over MRI alone for identifying small pituitary tumors associated with Cushing disease, according to a study published March 21 in the Journal of Nuclear Medicine.
In patients diagnosed with the disease yet who had inconclusive MRI results, PET/MRI was positive in 100% of cases, noted lead author Ilanah Pruis, a doctoral student at Erasmus University Medical Center in Rotterdam, Netherlands.
“This multimodal imaging technique provides a welcome improvement for diagnosis, planning of surgery, and clinical outcome in patients with Cushing disease,” the authors wrote.

Can cardiac PET/CT ‘revolutionize’ heart care?
PET/CT is poised to become a key tool for imaging the coronary arteries – a clinical imaging exam that can reveal early warning signs of fatal conditions when patients present with symptoms of chest pain, experts say.
The “hybrid” scan – which combines molecular PET and anatomical CT images – may have its highest potential in visualizing early signs of so-called “perfusion deficits” (regions of obstructed blood flow), said Marcelo Di Carli, MD, a professor of radiology and medicine at Harvard Medical School, in a recent interview with AuntMinnie.com.
“[PET/CT] helps us differentiate a patient who has ches...

Imaging Biometrics touts study on DSC-FTB mapping
Imaging Biometrics, a wholly owned subsidiary of IQ-AI, is highlighting results from a recent study published in the American Journal of Neuroradiology.
The study, led by Michael Iv, MD, from the Stanford University Medical Center, found that dynamic susceptibility contrast (DSC) MR perfusion improved interreader agreement and confidence in neuroradiologist interpretation. The company touted that its DSC-fractional tumor burden (FTB) resulted in the highest agreement in BT-RADS scores among all raters as well as the highest confidence scores for interpretation.
The company also noted the high level of agreement with the ...

EVT valuable in patients requiring transit to stroke centers
In this study, the researchers conducted a subgroup analysis using data from a recently completed clinical trial that compared EVT to standard medical management at 31 centers across North America, Europe, Australia, and New Zealand. In the trial, hospitals without neurointerventional teams transferred participating patients to EVT-capable centers.
The group culled data on these patients and assessed EVT treatment effects, as well as associations between transfer times and neuroimaging changes.
Out of 352 enrolled patients (median age, 66.5 years old), a total of 211 patients were transfers, of whom 108 (51.2%) received ...

Music calms patients undergoing imaging procedures
Music can be calming for patients undergoing medical imaging, an article published February 7 in Radiography suggests.
A team led by Lina Viera, PhD, from the Lisbon Polytechnic Institute in Portugal found that musical interventions, whether they be classical songs or sounds of nature, can reduce anxiety and heart rate outcomes in patients. This includes imaging procedures such as MRI, mammography, and PET among others.
“Musical intervention arises as a painless, reliable, low-cost, and side-effect-free strategy, presenting imaging departments with a practical means to enhance patient comfort and mitigate anxiety and s...

EVT improves outcomes in stroke patients
Endovascular thrombectomy (EVT) may improve outcomes in stroke patients compared to medical management – importantly, even when imaging suggests varying ranges of brain injury, according to a study published February 7 in JAMA.
In a clinical trial, EVT improved clinical outcomes after 90 days in patients with a wide spectrum of infarct volumes (stroke sizes) assessed either by CT or MRI imaging at baseline, noted a group led by Amrou Sarraj, MD, of Case Western Reserve University in Cleveland, OH.
“EVT treatment effects and outcomes may differ by imaging selection modalities and are not well characterized in patients...

Use CT first to triage chest pain patients for revascularization
A "CT first" strategy is an effective way to determine if patients with stable chest pain need revascularization with invasive coronary angiography (ICA), researchers have found. The results could improve patient care by helping them avoid unnecessary ICA -- and could curb healthcare costs, said senior study author Markus Scherer, MD, of Atrium Health-Sanger Heart and Vascular Institute in Charlotte, NC. The study findings were presented February 1 at the American College of Cardiology (ACC) Cardiovascular Summit, underway in Washington, DC."While care must be individualized, for patients with unknown or unestablished ...
