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. 

3D hologram system for guiding precision surgery gets FDA nod

The FDA has approved an augmented reality system that renders 3D holograms from CT images to guide surgeons operating the spine such that they don’t need to toggle their eyes between the patient and a monitor.

Ultrasound ‘grand challenge’ launches to promote global POCUS proficiency

A nonprofit healthcare-certification organization is challenging every user of medical ultrasound in the world to become proficient and certified in the modality by 2030.

~1 hour a day per radiologist: Time saved by workflow-integrated AI for chest CT

When AI-generated annotations of real-world chest CT images were made available to interpreting radiologists in a randomized prospective study, the assisted rads cut their read times from 421 seconds to 328.

Do race and ethnicity impact the accuracy of diagnostic mammograms?

There are many known disparities in breast imaging that have been found in previous studies, but insight into diagnostic mammography processes is still lacking.

The benefits of preoperative prostate MRI are clear, so why isn't every man getting one?

Preoperative MRI use increased substantially from 2003 to 2016—from 2.9% to 28.2% to be exact—but the modality remained underutilized in certain regions and among specific populations in the United States.

Researchers have designed a new cardiac SPECT imaging system that could potentially deliver images much faster than current models. The team presented its findings at the annual meeting of the Society of Nuclear Medicine and Molecular Imaging (SNMMI), SNMMI 2022.

The need for speed: New-look cardiac SPECT imaging system could be up to 100 times faster than current models

Researchers presented their proposed design of a self-collimating SPECT system at SNMMI 2022.

A comparison of standard 2D mammography (right) and digital breast tomosynthesis (DBT), or 3D mammography (left). The DBT creates a data set of 1 mm slices that the radiologist can look through to see more detail in suspect areas and determine if it dense breast tissue is masking a tumor.

DBT is better for women with increased breast cancer risks

For the research, special attention was paid to women with dense breasts and other factors that raise their risk of a breast cancer diagnosis.

FDA clears 3D print application for head/face and ortho structures

A new system for developing and printing 3D models of tissue and bone from clinical CT images has been regulatorily OK’d for sale in the U.S.
