An example of measurement on plain anterior-posterior x-rays used in the study: canal-bone-ratio CBR-7 cm (Cm/Cc) and CBR-10 cm (Dm/Dc), canal-calcar ratio CCR (Dm/Bm); canal flare index CFI (A/Dm). Image courtesy of Scientific Reports.
Functional MRI shows brain activity prompted by fanaticism
By Kate Madden Yee
Functional MRI shows brain activity sparked by fanaticism, according to a presentation to be delivered at the upcoming RSNA meeting.
November 21, 2023
The contrast of winning and losing in the 'good fanatic brain.' The image shows in warm colors the activity related to a significant victory. The blue scale represents the activation related to a significant loss; this pattern is congruent with the Mentalization Network, which suggests a rationalization process of the pain evoked by the losing scenario.

FAPI-PET shows promise for detecting pancreatic cancer
By Will Morton
FAPI-PET imaging may become a powerful diagnostic tool for detecting pancreatic cancer.
November 20, 2023
A male patient with suspected recurrent pancreatic cancer. Contrast-enhanced CT shows mass around superior mesenteric artery after pancreatectomy. F-18 FDG only shows discrete uptake of lesion (SUVmax, 3.8), whereas Ga-68 FAPI clearly visualizes recurrent tumor. Patient received adjuvant chemotherapy after Ga-68 FAPI. Patient denied recommended chemotherapy. Increase of CA19-9 levels (from 240 U/mL to 767 U/mL) and follow-up imaging eight months later validated progression of mesenteric mass as well as increased F-18 FDG uptake (SUVmax, 5.3).
