Although current guidelines recommend radiologists evaluate CAC on all non-gated, non-contrast chest CT scans, the authors of the study note that these guidelines are not consistently followed.
The results of a survey completed by more than 13,000 respondents who were eligible for the cancer screening revealed that less than 2% of eligible participants underwent CTC exams.
A new study found that while the absolute number of imaging studies performed in 2016 was twice the number of studies performed in 2004, the increase is attributable to a doubling in the number of active patients.
HeartFlow’s non-invasive cardiac computed tomography derived fractional flow reserve (FFR-CT) technology enables FFR values for the entire coronary tree of a patient using just a CT scan. This can show the significance of any coronary plaque lesions and if a patient needs to be sent to the cath lab for revascularization, or if they can be treated medically.
Experts have developed an artificial intelligence model that can estimate gestational age with accuracy that rivals that of formally trained sonographers completing fetal biometry scans.
A 46-year-old patient with a strong family history of breast cancer had a screening ultrasound prior to COVID-19 vaccination demonstrating a morphologically normal left axillary lymph node. (B) 25 days following the second dose of the COVID-19 vaccination, the patient presented with a palpable lump in the left axilla and ultrasound demonstrated enlarged lymph nodes with cortex measuring up to 6 mm in thickness (arrow). (C) A follow-up ultrasound 21 weeks following demonstrated stable axillary lymphadenopathy. (D) An ultrasound-guided core biopsy was then recommended and pathology demonstrated lymphoid cells negative for carcinoma. Image courtesy of RSNA
New research shows that persistent lymph node swelling observed on imaging can persist beyond 12 weeks post-vaccination for up to 50% of women.
Despite increases of 250% for CTA and 428% for CTP, researchers observed lower rates of neuroimaging utilization among rural residents, older individuals (80 years and above), women and Black patients.
