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.

Release the 'Krakencoder': New algorithm gives scientists unprecedented insight into neural function
Researchers are hopeful that a new technology named after a tentacled folklore sea monster can help scientists better understand the anatomy of the brain.
Ultrasound-guided thermal ablation safer, as effective as surgery for papillary thyroid cancer
Though surgery is the current standard of care, experts believe ablative strategies "may become the primary choice for PTC treatment" in the future.
ACC backs AMA resolution to boost lung cancer and heart disease screenings in smokers with low-dose CT scans
Former American College of Cardiology president Kim Allan Williams, Sr., MD, an ACC delegate to the American Medical Association House of Delegates, discusses an AMA resolution aimed at improving public awareness of low-dose CT lung cancer exams that can screen for coronary artery calcium at the same time.
AI prediction reduces radiologists' prostate MRI-related workloads by 20%
With prostate MRI assessments now being utilized more frequently, experts suggest AI could offer a more sustainable approach to managing growing workloads.
Single emergency department charts 90% uptick in CT use since 2015
The uptick came during a time when the number of ED episodes increased by only 8% at the same institution, with defensive medicine one possible driver.

PET/MR: still struggling to solidify clinical practice

There are two main questions that remain on the minds of those evaluating PET/MR for clinical practice: Is PET/CT just as good? If yes, isn’t PET/CT cheaper? These questions are answered with a resounding ‘sometimes,’ according to a review published Feb. 20 in the Journal of Nuclear Medicine.

Biomolecule optical imaging trumps fluorescence for the small

Imaging small biomolecules in living cells and animals just took a huge leap over the conventional restrictions of fluorescence imaging. Scientists at Columbia University in New York City have developed a means of observing miniscule molecular materials using novel chemistry and physics.

Alzheimer’s research: Culprit of deadly tau aggregation found

Understanding tau behavior in Alzheimer’s disease could alter the course of diagnostics and therapy development. Research conducted in part by scientists at the Technische Universitat Munchen (TUM) has revealed an essential mechanism of tau deposition and neurodegenerative disease, the institution announced today.

Aptamer-based molecular agents have arrived

Biomarkers built upon aptamers rather than peptides and antibodies offer multiple advantages for molecular imaging and several are currently under development, according to a review published Feb. 13 in the Journal of Nuclear Medicine.

ASNC now taking abstracts for 2014 scientific session

The American Society of Nuclear Cardiology (ASNC) announced Feb. 27 that abstract submissions are now being taken for the upcoming ASNC 2014 meeting scheduled for Sept. 18-21 at the Seaport World Trade Center in Boston.

SPECT tracks colorectal tumor-sniping chemoradiotherapy

A treatment strategy for colon cancer combining molecular imaging, a radioimmunotherapy that seeks colon-specific anatomy and concomitant chemotherapy is being bundled as chemoradiotherapy to take out more metastatic disease, according to a study published online Feb. 20 in the Journal of Nuclear Medicine.

PET parameter is better than a visual read for Hodgkin's lymphoma

A reduction of the FDG maximum standardized uptake value is superior to visual analysis for the evaluation of treatment response in patients with Hodgkin's lymphoma, according to a study published online Feb. 24 in the Journal of Nuclear Medicine.
