Computer tomography (CT) has produced stunning images and improved diagnosis and treatment of myriad health complications. A German research team has developed an imaging technique called nano-CT that produces images at resolutions up to 100 nanometers, a marketed improvement from the 500 nm in traditional CT methods.

The NIH has announced the formation of a five-year, $70 million effort to organize, coordinate and otherwise accelerate new research into Alzheimer’s disease and other dementias.

Recent research, led by Chris Wu, MD, with the department of ophthalmology at the New York Eye and Ear Infirmary of Mount Sinai in New York, in JAMA Ophthalmology discussed the case of one woman who experienced acute solar retinopathy, where researchers used adaptive optics scanning light ophthalmoscopy to gather high-resolution images of her eye structures.

South Korean researchers have used a budding machine-learning technique to generate high-quality structural MR images from amyloid PET scans of dementia patients’ brains. They were then able to quantify cortical amyloid load from these MR-less images, which may open the door to ordering PET scans alone for numerous imaging scenarios in which PET/MR is now a preferred diagnostic pathway.

Tinnitus—the perception of sound, often ringing, without external noise—can be a difficult condition to treat, because, in many cases, an exact cause cannot be identified. Recent work presented at RSNA 2017 showed promise, though, by using neurofeedback and functional MRI (fMRI) to identify activity in the brain’s auditory cortex.

AI technique turns PET scans into MR images

RSNA 2017: fMRI, neurofeedback may help quiet tinnitus

Tinnitus—the perception of sound, often ringing, without external noise—can be a difficult condition to treat, because, in many cases, an exact cause cannot be identified. Recent work presented at RSNA 2017 showed promise, though, by using neurofeedback and functional MRI (fMRI) to identify activity in the brain’s auditory cortex.

Common characteristics in sonograms of malignant thyroid nodules

Up to two-thirds of thyroid ultrasound examinations will reveal nodules, though only a small percentage prove to be malignant. Fine-needle aspiration cytology (FNAC) can help distinguish between malignant and benign tissue, but the test is not cost-effective in every case.

Could $10 microchip turn standard ultrasound into 3D imaging technique?

Despite what countless click-bait advertisements may promise, “one simple hack” rarely changes your life. But a new imaging technology from Duke University Health System may pack plenty of potential for changing ultrasonic capabilities.

PET staging charts illustrate Alzheimer's progression, amyloid development

A new study conducted by a team of researchers led by Michel Grothe of the German Center for Neurodegenerative Diseases in Rostock, Germany, announced the development of a four-stage model of regional amyloid beta (Aβ) protein deposition that can be found in patients with Alzheimer's, according to an article by Alzforum. 

Gestational age matters in brain development at birth, but preemies can catch up in childhood

Longer gestation during normal pregnancy is associated with significantly greater development of white matter in babies’ brains. However, similar associations are no longer present by the time children are 8 years old. The lack may confirm that white-matter development in the brains of preemies tends to catch up as these children grow.

FDA greenlights Siemens Healthineers’ 7T MRI for clinical use

In a first, the FDA has cleared a powerful 7-tesla MRI scanner for clinical use.
