Deep-learning model characterizes PET/CT findings
November 1, 2019 -- An artificial intelligence algorithm shows a promising level of accuracy for identifying normal and abnormal results on FDG-PET/CT exams, and it could potentially help radiologists avoid missed findings, according to research published online October 28 in the Journal of Digital Imaging.

CEDM, MBI outperform MRI for breast cancer staging
October 31, 2019 -- Contrast-enhanced digital mammography (CEDM) and molecular breast imaging (MBI) are comparable to breast MRI when it comes to identifying breast cancer, but CEDM and MBI outperform breast MRI when it comes to treatment staging, according to a study published online October 29 in Radiology.

Is PET really necessary to predict oncoming Alzheimer's?
October 21, 2019 -- Can a person's progression from mild cognitive impairment to Alzheimer's disease be reliably predicted without PET imaging? A new study published online October 18 in the Journal of Nuclear Medicine lists several nonimaging methods that could offer a better prognosis than the modality. Read More
Image processing shows potential to reduce MBI dose
October 10, 2019 -- Postprocessing software shows promise for reducing the radiation dose of molecular breast imaging (MBI) -- making way for more widespread adoption of the modality for breast cancer screening in women at higher risk or with dense breast tissue, according to a study published online October 9 in the American Journal of Roentgenology.

Automated bone scan software proves worth with radium-223
October 10, 2019 -- An automated bone scan algorithm has shown its value in determining the response to radium-223 (Ra-223) treatment for patients with metastatic castration-resistant prostate cancer, according to a study published online October 4 in the Journal of Nuclear Medicine. Read More
Ga-68 PSMA-11 PET interpretation criteria need work
October 2, 2019 -- Interpretation criteria for gallium-68 (Ga-68) prostate-specific membrane antigen-11 (PSMA-11) PET with CT or MRI for prostate cancer can bolster interreader agreement, but some performance issues remain, according to a study published online September 27 in the Journal of Nuclear Medicine.

MBI useful in particular breast screening scenarios
October 1, 2019 -- Molecular breast imaging (MBI) is outperformed by mammography in most breast cancer screening scenarios, but it still belongs in the breast cancer screening arsenal, according to a literature review published September 27 in the new journal Radiology: Imaging Cancer. Read More
PET/CT beats SPECT for neuroendocrine tumors
September 27, 2019 -- PET/CT performed better than planar scintigraphy or SPECT for determining which patients with neuroendocrine tumors are most likely to benefit from peptide receptor radionuclide therapy, in a study published in the September issue of the Journal of Nuclear Medicine. Read More
Rethinking Ga-68 PSMA-11 PET/CT for bone metastases
September 26, 2019 -- Researchers from the University of California, Los Angeles say it is time to reconsider guidelines in favor of broader use of gallium-68 (Ga-68) prostate-specific membrane antigen-11 (PSMA-11) PET/CT to detect bone metastases in prostate cancer patients, based on findings in their study published September 20 in the Journal of Nuclear Medicine.
