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. 

Altered mental status and head CT: Study suggests the exam is overutilized at the expense of patients

The meta-analysis included 25 studies and nearly 80,000 patient cases. Experts found that while 94% of those patients with acute atraumatic AMS underwent non-contrast head CT scans, just 11% of those exams yielded positive results. 

Examples of breast imaging. What does breast imaging look like? What does breast cancer look like? What do radiologists look for on mammograms?

New findings ‘challenge the use of imaging surveillance’ after any mastectomy

Regardless of whether or not they received reconstructive surgery, post-mastectomy patients probably need no follow-up imaging for breast cancer.

'Crash course' on COVID cases benefits residents less experienced with thoracic CT

Following the course, experts observed nearly perfect agreement between less experienced residents and chest-devoted radiologists.

Philips MRI

Amid looming helium shortage, Philips enters research agreement to study alternative cooling methods for MRI scanners

The healthcare industry accounts for close to 30% of global helium consumption, with MRI equipment needs accounting for a significant portion of that figure.

AI generates imitation lung X-rays replete with diagnosable pathologies

Stanford researchers have created synthetic yet highly realistic chest X-rays by customizing an open-source AI model called Stable Diffusion for rendering text as images.

MRI data reveal how pandemic-related stress physically aged the brains of teens

Researchers involved in the study suggested that, until now, this sort of growth acceleration in adolescents had only been observed in children who had experienced extreme adversity, such as violence, neglect and family dysfunction.
