Digital mammograms yield more info for radiomics than synthetic images

By Amerigo Allegretto

Digital mammograms may be best for informing radiomics models that assess breast density.

Delineation workflow: The various steps of the contouring process: (a) the nipple is manually annotated (b) a reference point is placed 30 mm behind the nipple (c) 10 random theta/displacement values are selected to obtain the central point of each ROI (d) Regions of interest are placed on the image. (e) The resulting 10 ROIs obtained for a representative subject (viewing window [0 10000]). Images are published under a Creative Commons license (CC BY-NC-ND 4.0).

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.

PSMA-PET tracer performs well in clinical trial

PET/CT imaging with a new gallium-68-based prostate cancer radiotracer shows promise for detecting recurrent metastatic disease.

February 20, 2025

(A) Representative maximum-intensity projection and selected PET/CT images (fused, PET and CT only) of patient with metastatic prostate cancer at 1 hour after injection. (B and C) Low uptake of Ga-68 PSMA-R2 in salivary and submandibular glands is also demonstrated. (D) Images show heterogeneous uptake of Ga-68 PSMA-R2 with varying degrees of intensity in multiple spine bone lesions (vertebral sclerotic lesion with intense PSMA-R2 expression at its periphery indicated with red arrow).

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.
