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.

AMA resolution backs expanded low-dose CT screenings for lung cancer, heart risk
Dana Smetherman, MD, CEO of the American College of Radiology, discusses the policy, which urges for more robust promotion of low-dose CT as a public health tool.
First AI-enabled POCUS app for detecting pleural effusion and atelectasis earns FDA clearance
The apps are embedded into the Exo Iris transducer, which can be plugged directly into a smartphone, utilized anywhere and without the internet.
Symptom-detected breast cancers more likely to require mastectomy, chemotherapy
New research adds to the “strong evidence” supporting screening guidelines and highlights the importance of women adhering to clinical recommendations.
3 industry partnerships, 1 clinical aim: Enriching the global supply chain of medical isotopes
Nuclear medicine operations may soon enjoy steadier flows of certain in-demand radioisotopes. If so, much credit will go to companies that had the strategic sense to collaborate with each other.
Shoulder ultrasound effectively detects insulin resistance, even before abnormal labs
POCUS could represent a quick, easy and affordable way to detect signs of insulin resistance before it progresses into diabetes, researchers suggest.

New MRI technique a ‘virtual biopsy’ for surveilling transplanted hearts

Researchers have developed a novel cardiovascular MRI protocol as an option to the invasive gold standard, endomyocardial biopsy, for monitoring heart-transplant patients at risk of suffering organ rejection.

AI inspects endotracheal tube placement on chest X-rays

Radiology researchers have demonstrated the reliability of an AI system they developed to automatically check placement of endotracheal tubes on chest X-rays.

Diffusion-weighted MRI boosts detection of locally recurrent pancreatic cancer

MRI with DWI images showed higher sensitivity in detecting local recurrence after PDAC resection.

PET/CT contrast debate: ‘Time to unleash the full power’ vs. ‘More is not always better’

Hybrid PET/CT enhanced with intravenous CT contrast deserves wider acceptance and adoption, as diagnostically optimized CT can complement PET—and vice versa—for a variety of potential indications. That’s one opinion on the matter.

ACR working with FDA and HHS to help address imaging contrast shortage

The American College of Radiology (ACR) announced this week its government relations staff has been engaging federal agencies in an effort to improve product availability and hasten resolution of the ongoing iodine contrast shortage.

New imaging technique detects post-COVID lung abnormalities

Conventional imaging did not detect the abnormalities, which MRI scans identified up to one year after infection.

Primary care POCUS on the Old Continent: Guidance needed, but at least 1 use case deemed ‘useful and feasible’

Two European studies illustrate opportunities and challenges presented by the growing appeal of point-of-care ultrasound to primary care practices.

The American Society fo Nuclear Cardiology (ASNC) did not support the 2021 Chest Pain Guidelines because of the high support for cardiac CT and FFR-CT.
