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.

Dynamic optical imaging predicts treatment outcomes in breast cancer patients

In patients with early-stage breast cancer, neoadjuvant chemotherapy (NAC) is a common treatment to reduce tumor size before surgery. A team has found dynamic diffuse optical tomography (DDOT) can detect if a tumor has responded to chemotherapy within two weeks of initial treatment—potentially life-saving information for patients. ​​​​​​​

New machine learning algorithm reveals biological networks in human cells

Northwestern University researchers may have uncovered how parts inside human cells interact with each other thanks to a newly developed machine learning algorithm technology.  

New AI imaging from Indian start-up tackles TB diagnosis

Qure.ai, a health tech start-up in Mumbai, India, has developed an artificial intelligence (AI)-powered technology able to analyze x-rays, MRI and CT scans to identify and improve disease diagnosis, according to a report from Livemint.com.

Study: Harms of false-positives in mammography may be exaggerated

False-positive stereotactic vacuum-assisted breast biopsies (SVABs) may not negatively affect subsequent mammographic screenings, according to a recent study published in the Journal of the American College of Radiology (JACR). The harms of false-positives, according to reserachers from the Center for Biomedical Imaging at New York University School of Medicine, may be exaggerated.

Focused ultrasound burns hole in patient's brain, stops essential tremor

The University of Maryland Medical Center is burning holes in the brains of its patients—and for good reason. According to a recent NBC report, the medical center used focused ultrasound thalamotomy on a 60-year-old man to successfully stop palsy-induced essential tremor on the left side of his body.  

Cryo-electron tomography finds cell transport linked to neurological disorders

Researchers from the Scripps Research Institute (TSRI) have provided what they claim is the first 3D visualization of the dynein-dynactin complex bound to microbubbles, which is responsible for cell division and preventing the development of neurological diseases.
