Should PET/CT be used in pregnant women with suspected cancer? Experts recommend against it, but some would consider it in carefully selected cases.

June 14, 2021 -- PET imaging with a gallium-68 (Ga-68)-labeled fibroblast activation protein inhibitor (FAPI) shows promise as an effective way to identify and monitor pulmonary fibrosis, according to animal study findings presented at the virtual 2021 Society of Nuclear Medicine and Molecular Imaging (SNMMI) annual meeting. The technique could add molecular imaging to the lung disease toolbox -- and perhaps reduce the number of biopsies, said study lead author Carolina de Aguiar Ferreira, PhD, of the University of Wisconsin-Madison in a statement released June 12 by the SNMMI. "Further valid...

Researchers from the University of Minnesota compared more than five years of data on the effects of three different dietary modifications prior to FDG-PET/CT scans in patients suspected of cardiac sarcoidosis. They found that a 72-hour daytime ketogenic diet resulted in increased myocardium suppression and diagnosis rates. "Two of these dietary modification strategies are mainly applied and recommended by current guidelines and the third one, which performs better, has not been used in the clinical setting despite preclinical evidence to support its use," stated radiologist Dr. Can Ozutemiz...

In a direct comparison with gallium-68 (Ga-68) prostate-specific membrane antigen (PSMA) PET/CT, MR imaging with a ferumoxtran-10 nanoparticle contrast agent (nano-MRI) identified significantly more suspected serious lymph nodes, as well as nodes that were significantly smaller. At the same time, the two approaches were fairly complementary, as they both discovered some lymph nodes the other modality missed. "Although there is no reference standard in this study, the main results mentioned above provide insight into the complementary performance of both modalities by identifying aspects where...

Underwent something called a pet ct which does the job of trying to figure out whether the tumor has spread. thus far the only spots that were seen were four spots on the brain which i should add were considered rather small enough that he might be able to get very localized radiation therapy, rather than getting the whole brain radiated. >> in october he'll turn 91. how does that factor in how does that factor in to the treatment? >> that's a great question. oncologists generally think the tolerance of the drug is pretty good. it can have side effects, joint pain and nausea and rash and diarr...
