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.

New Zealand-based Wellumio in January announced its expansion into the U.S., laying the groundwork for local clinical trials to test its device.
Breast ultrasound finding may signal invasive cancer, research suggests
Though this finding is relatively uncommon, it is expected that the BI-RADS 6th edition ultrasound lexicon will include it as a feature associated with malignancy.
AI model nearly halves false positive rates for lung cancer CT screenings
Reducing false positives could decrease the frequency of unnecessary procedures, lower the associated costs and also ease patient anxiety concerning CT results.
A robot may soon be handling patients' ultrasounds in a Wisconsin health system
The machine will be operated remotely by a sonographer who has been trained to conduct remote ultrasound exams.
ED pivots to virtual radiology service, slashing CT turnaround times and lengths of stay
Syracuse, New York-based Upstate Medical University had previously relied on rad residents to handle initial reads, with attendings finalizing interpretation in the a.m.

There were several point-of-care ultrasound (POCUS) systems on display by vendors at ACC 2022. Here are two of them.

FDA greenlights portable, wearable 3D breast POCUS

The patient wears the device while the machine essentially operates itself.

Most states' breast cancer screening plans do not comply with USPSTF guidelines

Of the 51 plans, just 31% were consistent with the USPSTF recommendations pertaining to the starting age and frequency of screening women who are at average risk of developing breast cancer.

Major teaching hospital finds half its on-call abdominal ultrasounds call utilization into question

The investigators encourage radiologists to consider the numbers and take steps to “reinforce their gatekeeper function” to help cut ultrasound overutilization.

American Indian/Alaskan Native tribes three times more likely to get lung or colorectal cancer

This week presenters at the annual ARRS meeting discussed barriers these populations face when trying access vital cancer screenings.

Lung cancer risk increases with emphysema severity

Researchers analyzed a total of 21 studies that included more than 107,000 patients who had undergone CT assessments to examine associations between emphysema and lung cancer.

Deep learning and rads comprise an ‘efficient pipeline’ for detecting, classifying thyroid nodules

Competing to classify thyroid nodules on ultrasound images as either malignant or benign, three deep learning models have essentially drawn a tie with four radiologists.
