Do more CT scans lead to more kidney surgeries?
The higher the number of chest or abdominal CT exams in a hospital referral region, the greater the probability that patients will undergo a renal procedure, likely due to the incidental detection of renal masses, according to a study published online December 26 in JAMA Internal Medicine.

Doctors who order fewer CTPA scans detect more PE
Turns out that less really is more. Canadian researchers are reporting that doctors who order fewer CT pulmonary angiography (CTPA) scans for pulmonary embolism (PE) actually have a higher rate of successfully detecting the condition, according to a letter published online January 8 in JAMA Internal Medicine.

Risk-based lung cancer screening tops USPSTF guidelines
Using individual risk-based criteria to determine eligibility for CT lung cancer screening may avert more deaths from cancer than using current U.S. Preventive Services Task Force (USPSTF) guidelines, according to research published online January 1 in the Annals of Internal Medicine.

Gadolinium in fetuses almost entirely cleared via placenta
Only trace amounts of the gadolinium administered to pregnant monkeys cross the placenta and enter the fetuses, and most of this gadolinium quickly returns back to the mother's bloodstream for excretion, according to research published in the January issue of Radiology.

How often are lung nodules missed on CAC scoring scans?
If an incidental lung nodule is present on a CT coronary artery calcium (CAC) scoring scan, how often is that nodule actually detected and worked up? Not as often as one might expect, according to researchers who analyzed the reasons why nodules might be missed in a presentation at RSNA 2017.

FFR-CT algorithm guides management of revascularization
A deep-learning algorithm that analyzes fractional flow reserve CT (FFR-CT) scans was able to determine almost as well as invasive FFR which patients suspected of having coronary artery disease should be referred for revascularization. The finding could lead to better, less-invasive care, according to a presentation at RSNA 2017.

MRI links long-COVID brain fog to lung function
By Will Morton
MRI shows that lower pulmonary gas exchange in the lungs of long-COVID patients may be associated with cognitive symptoms.
November 26, 2024
Individuals in the study were plotted with the x-axis being rank of pulmonary gas exchange. The black dots show the pulmonary gas exchange ratio (red blood cell to tissue plasma ratio, RBC:mem) on the left y-axis and the blue dots are the cognition scores on the right y-axis. Gas exchange maps of three representative patients from a low, medium, and high pulmonary gas exchange. Image courtesy of RSNA.
