Novel 3D MRI technique could improve brain metastases detection
Monday, December 2 | 10:30 a.m.-10:40 a.m. | SSC11-01 | Room N226Japanese researchers have developed a new 3D MR technique that can simultaneously acquire images with and without blood vessel suppression and may help detect brain metastases.

DWI, PET/CT help in rectal cancer detection and assessment
Sunday, December 1 | 12:05 p.m.-12:15 p.m. | SSA07-09 | Room E450AItalian researchers have found that diffusion-weighted MRI (DWI-MRI) offers higher specificity than PET/CT in rectal cancer patients, especially in cases of active inflammatory tissue, but PET/CT has a higher sensitivity and can detect distant metastasis.

US confirmation of suspect breast MRI means aggressive cancer
Wednesday, December 4 | 3:10 p.m.-3:20 p.m. | SSM02-02 | Room E451AWhen a suspicious breast MRI lesion has an ultrasound correlate, it is more likely to be an aggressive cancer, according to a study to be presented during this Wednesday afternoon session.

PET/MRI could be alternative to PET/CT for liver lesions
PET/MRI is more than adequate in characterizing liver lesions and provides greater lesion conspicuity than PET/CT, offering clinicians a powerful alternative for oncology imaging, according to a German study published in the November issue of the European Journal of Radiology.

FDA approves GE's Vizamyl PET radiotracer for dementia
U.S. physicians looking to detect early signs of Alzheimer's disease now have a second tool in their arsenal with the U.S. Food and Drug Administration's approval of Vizamyl (flutemetamol F-18 injection), a radiopharmaceutical from GE Healthcare for use with PET imaging of the brain in adults being evaluated for Alzheimer's and dementia.

FAPI-PET shows promise in head and neck cancer patients
By Will Morton
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.

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.
