FAPI-PET shows promise in head and neck cancer patients

In a comparative imaging trial, FAPI-PET/CT outperformed FDG-PET/CT in detecting primary tumors in patients with head and neck cancer.

PET/CT and MR images of a 72-year-old woman. (A) F-18 FDG-PET images (left and top) and PET/CT images (bottom) shown in coronal, sagittal, and axial views (from left to right), demonstrated a metastatic lymph node of the right neck with intensive metabolic activity (black arrow, SUVmax, 30.1) but presented no evidence for primary tumor. (B) Ga-68 FAPI-PET images (top and right) and PET/CT images (bottom), shown in axial, sagittal, and coronal views (from left to right), also detected metastatic lymph node with high Ga-68 FAPI tracer activity (black arrow, SUVmax, 16.3). There was intensive uptake of Ga-68 FAPI in palate (red arrow, SUVmax, 11.3). (C) T1-weighted, T2-weighted, and contrast-enhanced T1-weighted MRI also presented no evidence for primary tumor. Subsequent surgery confirmed mucoepidermoid carcinoma of palate. Image courtesy of the Journal of Nuclear Medicine.

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).
