Breast MRI offers clinicians a way to objectively measure BPE

By Kate Madden Yee

Breast MRI offers clinicians a way to objectively measure background parenchymal enhancement, or BPE -- which has been linked to increased breast cancer risk.

September 26, 2023

Examples of automatic fibroglandular tissue (FGT) segmentations on the precontrast (T1) non-fat saturated series and background parenchymal enhancement (BPE) extent on the postcontrast (T2) series for four control participants. For each participant, the left image shows the automated whole-breast segmentation (green line) and FGT segmentation (purple shading). The right image shows the areas of enhancement (red shading) within the FGT, defined as all voxels with 20% or more enhancement from the precontrast to postcontrast series. For each series, the middle section is presented. Example images were selected randomly within four categories defined by quantitative FGT volume (Vol) and BPE extent, where “low” refers to participants with measures in the bottom tertile and “high” refers to participants with measures in the top tertile. (A) Low FGT volume and low BPE extent in a 50-year-old premenopausal control participant. (B) Low FGT volume and high BPE extent in a 50-year-old control participant with a history of bilateral oophorectomy. (C) High FGT volume and low BPE extent in a 39-year-old premenopausal control participant. (D) High FGT volume and high BPE extent in a 44-year-old premenopausal control participant.

Radiologists outperform chest x-ray AI

Radiologists outperformed four commercially available AI algorithms when diagnosing lung diseases on chest x-rays.

Rare finding detected on PSMA-PET: A nonprostatic lung tumor

A group in Australia has described a rare finding during a prostate cancer restaging PET/CT scan – a pulmonary tumor embolism.

September 25, 2023

Hybrid contrast-enhanced CT (with iodinated contrast bolus timed to maximize pulmonary arterial visualization) and F-18 DCFPyL PSMA-PET images. Contrast CT images (A, B) show an eccentric filling defect in the superior lingula segmental artery of the left lung upper lobe (red arrow). This is concordant with moderately intense PSMA radiotracer expression (black arrows on axial PET-only images, C, and on whole-body maximum intensity projection image, E). Fused PET and contrast-enhanced CT axial image (D) also confirm the lesion (red arrow). No other site of PSMA expressing metastasis is evident on whole-body imaging (E).
