Molecular Imaging


In a recent editorial published in the November issue of The New England Journal of Medicine (NEJM), Werner Hacke, MD, PhD, DSc, discussed a new era of imaging selections for patients who are looking to benefit from a thrombectomy performed long after the onset of a stroke.

According to a new study published by the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine (AJRCCM), obstructive sleep apnea (OSA) may increase elderly individuals' risk of developing Alzheimer's disease.  

Using PET with the radiotracer 18F-florbetapir, researchers in Sweden have found that the topology of amyloid clusters can help tip off clinicians to the presence and progression of Alzheimer’s disease in patients who don’t yet present symptoms.

Radiology and orthopedics researchers at Stanford have shown the prowess of nuclear imaging for identifying the specific source(s) of pain and reduced mobility in patients with chronic sciatica, a common low-back condition notorious for evading such pinpointing.

The effects of space travel on the human anatomy are extensive to say the least, taking into account the harsh impact zero gravity and the rapid ascension into space have on the bodies of astronauts. Yet, the amount of information detailing the effects spaceflight has on the configuration of astronauts' brains is limited, claimed in a recent study published by The New England Journal of Medicine and funded by the National Aeronautics and Space Administration (NASA).

Triple-organ PET/MR can help manage eventual chemo effects in young cancer survivors

Many pediatric cancer survivors initially evidence no functional signs of chemotherapy damage only to develop serious organ problems months or years later. With this common vexation in mind, Stanford University researchers at Lucile Packard Children’s Hospital have piloted a surveillance protocol using PET/MR to find chemo-induced injuries lurking in the brain, heart and bone in a single imaging session.

Nuclear imaging combo can help predict Parkinson’s

When otherwise normally functioning adults with pronounced sleep problems and a weakened sense of smell also have two imaging biomarkers—reduced dopamine activity on SPECT and Parkinson’s-type pattern expression on FDG-PET—they’re probably headed for full-on Parkinson’s disease.

Amyloid PET makes a strong early showing in IDEAS study

Amyloid PET scans changed clinical care management in some 67.8 percent of 3,979 patients with mild cognitive impairment who are enrolled in the IDEAS study led by the Alzheimer’s Association and managed by the American College of Radiology and ACR’s Radiology Imaging Network.


PET/CT a sharp-eyed ally against comeback thyroid cancer

Postsurgical medullary thyroid cancer patients who have elevated calcitonin levels, which can indicate that the cancer has returned, are well served with follow-up PET/CT using the radiotracer 18F-DOPA (fluorine-18-L-dihydroxyphenylalanine), according to a small study published online May 30 in Nuclear Medicine Communications.

SPECT study shows ‘fish oil’ fatty acids benefiting the brain

A study running in the Journal of Alzheimer’s Disease bears out a correlation between higher concentrations of omega-3 fatty acids in the bloodstream with both better neurocognitive function and increased perfusion in regions of the brain that handle learning, memory, depression and dementia.

Pennsylvania patient area's first to receive ultrasound treatment for essential tremor

John Lukens, 61, who suffered from bilateral essential tremor (ET) for about a decade, recently became the first patient in Pennsylvania to receive MR-guided Focused Ultrasound Treatment (MRgFUS) for ET.

Bipolar individuals have abnormalities in frontal, temporal regions of brain

An international consortium spanning 76 centers published a large MRI study that found abnormalities in brain regions controlling inhibition and emotion in individuals with bipolar disorder.

Neuroimaging data used to construct viable aging biomarker

U.K. and Aussie researchers have introduced a clinically relevant neuroimaging biomarker of aging-related brain deterioration and, in the process, shown how brain age predicts mortality.  

3-modality fusion imaging may illuminate surgical guidance

Researchers at Pohang University in South Korea have demonstrated a three-modality method of fusion imaging that uses a photoacoustic component to deliver high-resolution visualization, suggesting the potential to supply comprehensive image guidance in real time during various surgeries.

Brain MRI shows gender-specific approaches should be considered in treating alcoholism

Researchers at Massachusetts General Hospital and Boston University School of Medicine used brain MRIs in a new study to find the effects of alcoholism on the brain’s reward system may be different in women and men.
