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.

FDA issues recall of Philips interventional imaging system due to safety risks
A communication error within the system can reportedly cause loss of imaging functionality mid-procedure.
FDA-cleared software increases throughput for flurpiridaz back-to-back rest-stress imaging
The new F-18 flurpiridaz radiotracer is expected to help drive cardiac PET growth, but it requires waiting between rest and stress scans. Software from MultiFunctional Imaging can help care teams combat that problem.
A new payer tactic: Using AI to curtail routine radiology claims, after imaging is already delivered
“Unlike [prior authorization], this model does not delay patient care and does not hold members liable to pay for unneeded exams,” writes radiologist Mark Hiatt, MD, MBA.
'Promising' new PET agent for brain metastases put on FDA's Fast Track
Clinical trial results thus far have been promising, representing a significant step forward for the hundreds of thousands of patients affected by brain metastases.
Cardiac imaging pioneer remembered for his joy and enthusiasm
Former American Society of Echocardiography president and well-known cardiac ultrasound pioneer Roberto Lang, MD, died at the age of 73. He helped develop 3D echo technology that is now used by care teams on a daily basis.

Construction of NorthStar’s new radioisotope facility is underway

NorthStar Medical Radioisotopes announced July 16 that the company had broken ground on the 50,000-square-foot production facility and headquarters in Beloit, Wis.

Proton detectors for better therapy

A cutting-edge detector developed by researchers in the United Kingdom and South Africa stands to spark more effective proton therapy for cancer patients.

PET imaging for myocardial innervation expands with F-18 labeled agent

First-in-human study of an investigational radiotracer, F-18 LMI1195, shows clear imaging of myocardial innervation via the norepinephrine transporter system—tipping off potential adverse cardiac events, according to a study published July 3 in the Journal of Nuclear Medicine.

Dementia numbers falling in some countries and underestimated in others

New cases of dementia are diminished in developed nations, which could be a sign of the successes of preventative care and reduced risk factors. On the other hand, dementia may have been sorely underestimated in countries with lower and middle incomes, according to research presented during the current Alzheimer’s Association International Conference (AAIC) in Copenhagen, Denmark.

AAIC 2014: Alzheimer’s risk factors in sharper relief

A number of factors are standing out as promoters for and protectors against the development of Alzheimer’s disease, according to research presented during the 2014 Alzheimer’s Association International Conference (AAIC) being held July 12-17 at the Bella Center in Copenhagen, Denmark.

Amino-acid PET imaging of gliomas in the spotlight

Amino-acid biomarkers have undergone an evolution in the imaging of gliomas. Several agents have shown to be particularly useful, most notably C-11 MET, F-18 FDOPA, FLT and FET, according to a review of amino-acid imaging published July 8 in the Journal of Nuclear Medicine.

FET-PET may monitor treatment response in glioblastoma

Preliminary research shows that O-(2-[18F]-fluoroethyl)-L-tyrosine (FET) could be used as a biomarker for response to chemoradiotherapy in glioblastoma patients, the University of West Australia School of Medicine announced last week.

Novel optical imaging system tracks toxicity via DNA accumulation

A preclinical imaging system that takes conventional microscopy and transforms it into a molecular imaging platform uses fluorescence and luminescence as well as radioisotope biomarkers and high resolution x-ray. The technique is called intravital microscopy, according to a study published online July 12 in Hepatology.
