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.

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.
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.
Contrast-enhanced mammography significantly improves early cancer detection
New trial results suggest CEM could enhance breast cancer detection beyond DBT exams when patients are faced with barriers to obtaining an MRI.
Bayer seeks FDA approval for gadoquatrane, its latest low-dose GBCA
The investigational agent uses 60% less gadolinium without sacrificing image quality, according to recent clinical trial findings.

The approach—called GammaTile—involves placing small radiation seeds at a tumor site during surgery.

New radiation therapy treatment stalls recurrence while sparing healthy tissue in patients with brain cancer

The treatment has the potential to “extend lifespans and improve quality of life” in patients with brain cancer, according to experts at UC San Diego Health.

MRI/PSA combo cuts down on unnecessary biopsies in patients with suspected PCa

The strategy of combining the two tests improved specificity and positive predictive value in detecting clinically significant cancer compared to PSA alone.

Long and longer: Imaging wait times in Canada

Prior to the arrival of COVID-19 in early 2020, Canadian patients waited nearly three months for an MRI and more than 11 weeks for a CT. Things have only gotten worse since then.

A study published this week in the Journal of the American College of Cardiology (JACC): Cardiovascular Imaging shows artificial intelligence (AI) algorithms can more rapidly and objectively determine calcium scores in computed tomographic (CT) and positron emission tomographic (PET) images than physicians.[1] The AI also performed well when the images were obtained from very-low-radiation CT attenuation scans. https://doi.org/10.1016/j.jcmg.2022.06.006

Artificial intelligence can objectively determine cardiac calcium scores faster than doctors

A new study shows artificial intelligence (AI) algorithms can more rapidly and objectively determine calcium scores in CT and PET/CT images than physicians.

Deep learning reconstruction levels playing field between 1.5T and 3T MRI exams

Denoising using deep learning techniques can boost the performance of 1.5T MR brain imaging, resulting in quality comparable or superior to 3T imaging.

'Radiologic serendipity' a common trigger event that ends in thyroid surgery in asymptomatic patients

In this cohort, experts found that just 34% of surgeries were performed on symptomatic patients, which shifted their focus to other potential modes of detection.

FDA clears X-ray system that produces hi-rez cine loops for chiropractors

Konica Minolta Healthcare has received FDA’s go-ahead to market a dynamic digital radiography (DDR) system.

Outreach team builds system to head off screening cancellations

Expanding available hours on top of calling with reminders did the equity-focused job with encouraging effectiveness.
