Heart valve-tracking algorithm boosts viability of 4D MRI

An automated heart valve-tracking algorithm halved the amount of time and variability involved in blood-flow quantification with 4D MRI, according to an article published online October 30 in Radiology. The improved efficiency may help convince clinicians that cardiac 4D MRI is useful for assessing valvular heart disease.

Road to RSNA 2018: CT Preview

The scientific presentations focusing on CT at this year's RSNA conference speak to the modality's impressive resilience and continued development. Artificial intelligence (AI) algorithms, computer-aided detection (CAD), and updated protocols that are helping to reduce radiation dose, as well as the results from early studies of ultrahigh-resolution CT scanners, will be key topics discussed at the meeting.

PET/CT reveals new infections in ICU patients

F-18 FDG-PET/CT is a valuable approach for diagnosing unknown infections in intensive care unit (ICU) patients.

February 21, 2025

There are several conceivable advantages of F-18 FDG PET/CT over conventional imaging. Image A and B showing an example of the distinctive capability of the F-18 FDG PET/CT. A shows a fusion image of F-18 FDG PET/CT and low-dose CT and B an high resolution chest CT of a patient with an Aspergillus infection. The suspected aspergilloma is concealed on the high resolution CT due to the lung fluids and consolidation. Image C and D (fusion image of F-18 FDG PET/CT and low-dose CT and low-dose CT only, respectively) are examples of the ability to image inflammation while no concurrent abnormalities are visualized, in this case prostatitis (red arrows). Image E, a maximized intensity projection of F-18 FDG PET, shows a patient with lung infections and multiple muscle abscesses after MRSA sepsis. This is an illustrative example of a relevant dissemination investigation.

LUS reliable for care strategies in infants with RDS

By Amerigo Allegretto

Lung ultrasound (LUS) scoring is reliable for determining whether preterm newborns need surfactant for suspected respiratory distress syndrome (RDS).

February 20, 2025

1Each lung has been split into three parts. Each area has been given a score between 0 and 3. Score values are shown in Ultrasonograms to match 4 different patterns. During a longitudinal scan with a high-resolution linear probe, pictures of patterns were taken. The scores are as follows: 0 means A pattern, 1 means B pattern, 2 means severe B pattern, and 3 means extended consolidation.

CT best for diagnosing suspected wooden foreign objects in the eye

By Kate Madden Yee

CT imaging is best for diagnosing suspected intraorbital wooden foreign bodies, although MR imaging does offer valuable supplementary information.

February 20, 2025

A 7-year-old boy, imaged 15 hours post-injury. Axial CT images with soft tissue windows (WW/WL=350/50) (a) reveal a rod-shaped foreign body (white arrow) situated along the course of the right inferior rectus muscle. The soft tissue window demonstrates that the foreign body exhibits attenuation similar to orbital emphysema. Axial CT images (WW/WL=1000/−200) at the same level (b) show that the attenuation of the foreign body (white arrow) is markedly different from that of the air in the sinuses.
