DCE-MRI determines women at high recurrence risk of breast cancer

By Amerigo Allegretto

DCE-MRI can help distinguish women with high recurrence risk of breast cancer from those with low recurrence risk.

January 24, 2024

Examples of quantification of background parenchymal enhancement (BPE) over fibroglandular tissue (FGT) on breast DCE-MRI scans from three patients. Images from left to right are the first postcontrast T1-weighted images, automated segmentation of the right and left breasts (red contours) and semiautomated tumor segmentation (yellow), automated segmentation of FGT (green), and quantification of BPE (purple) over the FGT regions. (A) Images of a 48-year-old woman diagnosed with invasive ductal carcinoma and assigned a low-risk Oncotype DX distant recurrence risk score (score, 13). The BPE measures at 20% cutoff value were ipsilateral absolute BPE within FGT relative to FGT volume (%BPEF/F) of 9.8% and contralateral %BPEF/F of 9.5%. (B) Images of a 60-year-old woman diagnosed with invasive ductal carcinoma and assigned an intermediate-risk Oncotype DX distant recurrence risk score (score, 19). The BPE measures at 20% cutoff value were as follows: ipsilateral %BPEF/F of 13.3% and contralateral %BPEF/F of 14.7%. (C) Images of a 54-year-old woman diagnosed with invasive ductal carcinoma and assigned a high-risk Oncotype DX distant recurrence risk score (score, 30). The BPE measures at 20% cutoff value were as follows: ipsilateral %BPEF/F of 34.1% and contralateral %BPEF/F of 14.5%. Image courtesy of the RSNA.

Elastography tracks stiffness changes in breast implants

By Amerigo Allegretto

Shear-wave elastography could be used as an indicator of breast implant rupture risk.

January 23, 2024

(A) Examples of B-mode images for the measurement of membrane thickness of implants from each of the four types of implants. Images are presented at the same scale. Membrane thicknesses (B) and then shear moduli measured by ARFI method (C) are compared without dissociation as a function of prosthesis age or implantation time. (NS: p-value > 0.05, *: p-value < 0.05, **: p-value < 0.01, ***: p-value < 0.001).

PET/CT improves diagnostic biopsy rates in lung cancer patients

PET/CT imaging can serve as a metabolic guide to increase the accuracy of needle biopsies in patients with suspicious lung nodules.

Patient with extensive lung and pleural disease. (2a) The PET/CT was available prior to the biopsy showing heterogeneous F-18 FDG radiotracer uptake and delineating the most accessible area of increased metabolic activity. (2b) The biopsy was targeted to the area of increased activity area and was positive for malignant diagnosis. Image courtesy of the European Journal of Radiology.
