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 study suggests link between birth defects and preconception CT imaging
The findings raise concerns about women who are planning on becoming pregnant and imaging-related radiation exposure in the weeks leading up to conception.
Radiation exposure during imaging may be causing some pediatric cancer cases
Although the risk of developing cancer due to radiation exposure during medical imaging is small, there are clear associations between the two.
Company building novel portable stroke MR imaging platform seeks investors
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.

Telerobotic ultrasound improves imaging access to underserved communities

Most examinations successfully answered clinical questions, doctors reported in the Journal of the American College of Radiology.

Abbreviated MRI outperforms DBT for detecting secondary breast cancer

“Our study results suggest that AB-MRI could potentially be sufficient for post-treatment surveillance,” experts suggested Thursday in Academic Radiology.

Researchers are developing a modified MRI protocol to help treat brain hemorrhages

“We are studying whether MRI can provide more complete information which could alter the clinical management of patients with hemorrhagic stroke," an expert involved in the trial explained.

Machine learning combined with PET/CT can predict heart attack risk

“We showed that risk prediction does not depend on cardiovascular risk scores, stenosis severity or CT calcium scoring," researchers said in the Journal of Nuclear Medicine.

Doctors suggest performing whole-spine MRI scans for suspected child abuse victims

Replacing cervical spine exams with whole-spine MRIs can reveal "major findings," investigators explained recently.

Fatigue impacts inexperienced breast radiologists’ performance, underlining importance of regular breaks

Physicians with five or fewer years of experience are more likely to order additional imaging when reading DBT exams later in the day.

Deep learning decreases CT radiation dose by 65% in patients with liver metastases

Scans using a smaller dose were accurate when detecting lesions 0.5 cm or larger but more research into low-contrast lesions is still necessary, experts cautioned.

Cutting CT overuse for appendicitis: 4 factors that distinguish high-performing hospitals

The role of a “radiation reduction champion," often filled by a radiologist, is pivotal to these efforts, experts wrote in the Journal of Pediatric Surgery.
