How high a price for incidental lung nodules on CT?
January 19, 2021 -- A new study published January 19 in JAMA Internal Medicine links overtreatment of incidental lung nodules found on CT with more radiation, adverse events, and higher health system costs. However, researchers couldn't determine whether or not it also resulted in earlier cancer diagnosis.  Discuss
FDA proposal to relax 510(k) rules on AI raises eyebrows
January 19, 2021 -- A proposal by the U.S. Food and Drug Administration (FDA) to eliminate 510(k) review for a number of artificial intelligence (AI) software applications is raising eyebrows in the radiology industry. The question is whether the proposal will be implemented after the Trump Administration ends this week.  Discuss
HIV drugs correlate with lower brain volumes on MRI
January 19, 2021 -- One of the largest-ever neuroimaging studies of individuals with HIV used MRI to reveal that lower current CD4+ T-cell counts were associated with smaller hippocampal and thalamic volumes in the brain. Also, the subset of participants not receiving treatment had smaller putamen volumes, according to findings published January 15 in JAMA Network Open.  Discuss
AI, radiomics predicts prostate cancer recurrence
January 19, 2021 -- A diagnostic model that incorporates artificial intelligence (AI) analysis of radiomics features on multiparametric MRI can predict the likelihood of prostate cancer recurrence prior to surgical treatment, enabling preoperative risk stratification of patients, according to research published in the January issue of EBioMedicine.  Discuss
CMS unveils final rule to speed up coverage of advanced tech
January 19, 2021 -- The U.S. Centers for Medicare and Medicaid Services (CMS) has issued a final rule designed to speed up Medicare coverage of innovative devices that have undergone prioritized regulatory review.  Discuss
Can MRI-guided breast biopsy evaluate chemo response?
January 19, 2021 -- MRI-guided breast biopsy looks like a promising method to evaluate complete response to neoadjuvant chemotherapy in women with breast cancer, according to the findings of a pilot study published January 15 in JAMA Network Open.  Discuss
Radiomics, AI can guide NSCLC treatment decisions
January 15, 2021 -- Radiomics and artificial intelligence (AI) can be used to guide treatment of non-small cell lung cancer (NSCLC) without the need for a biopsy, according to research presented January 13 at the American Association for Cancer Research Virtual Special Conference on Artificial Intelligence, Diagnosis, and Imaging.  Discuss
Report charts 80% drop in cardiac SPECT during COVID-19
January 15, 2021 -- A hospital in Alabama saw an 80% drop in the volume of SPECT myocardial perfusion imaging studies during the peak of the COVID-19 pandemic in spring 2020 as patients postponed nonessential procedures.  Discuss
CT radiomics classifies small nodules found in CT lung screening
January 15, 2021 -- A machine-learning algorithm can be highly accurate for classifying very small lung nodules found in low-dose CT lung screening programs, according to a poster presentation at this week's American Association for Cancer Research Virtual Special Conference on Artificial Intelligence, Diagnosis, and Imaging.  Discuss
Mammograms for inpatients could boost screening rates
January 15, 2021 -- Offering mammograms to low-income patients during an inpatient hospital stay could boost screening rates, according to the findings of a small pilot study published on January 11 in the Annals of Family Medicine.  Discuss
