Nearly 40% of MEDLINE-indexed radiology journals do not provide guidelines for AI generated content.

AI software improves diagnosis of lung conditions when contrast cannot be used

The machine learning-based software uses a formula called the Integrated Jacobian Formulation to calculate lung volume based on metrics derived from imaging taken during inhalation and exhalation. 

In individuals who have not completed a DEXA scan, head CT conducted for other reasons can offer insight into patients’ frontal bone density, a potential marker of osteoporosis.

depression and alcohol lead to impairment in functional connectivity of the brain

Alcohol dependence and depression are known to affect the functional connectivity of the brain, but when the two co-occur, connectivity between certain regions is significantly worse, new MRI study shows.

medical imaging carbon emissions climate change

Medical imaging machinery uses a lot of power, and the extent to which it quickens the pace of global warming is becoming clearer.

The curriculum consisted of sessions on movement, mindfulness, stress reduction, fulfillment in medicine, cognitive behavioral therapy, acupuncture, nutrition and cooking, free gym memberships and more.

gadolinium, GBCAs

The type of gadolinium-based agent administered could also increase the risk of reaction, a new study suggests.

breast radiologist breast cancer mammography

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

An international panel of experts recently developed and validated a reporting assessment scoring system that analyzes the location and extent of prostate cancer recurrence. 

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. #SNMMI22 #snmmi #SNMMI2022

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.

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

The new research, presented during ARRS 2024 in Boston, suggests CVD risk models may need to include certain findings identified in routine mammograms. 

PAD patients evaluated with HeartFlow's noninvasive FFRCT Analysis technology prior to surgery experienced much better outcomes, including a 63% lower risk of all-cause mortality after five years. 

The combination of AI and CT helped Nehal Mehta, MD, and colleagues track the performance of a new drug designed to target coronary inflammation.
