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.

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.

AAIC 2014 convenes in Copenhagen

The Alzheimer's Association International Conference is schedule to be held July 12-17 at the Bella Center in Copenhagen, Denmark. The meeting will feature many scientific sessions, plenary sessions and symposia dedicated to the most up-to-date Alzheimer's disease research.

Data uncover genomic signatures of most common lung cancer

Specific genetic mutations in an ear-marked pathway now have been implicated in the development of lung adenocarcinoma, the most prevalent subtype of lung cancer, according to a study published online July 9 in Nature. The discovery of these mutations could hone drug targets for new therapies down the road.
