CT depicts how COVID-19 abnormalities change over time
March 20, 2020 -- CT scans revealed rapid progression of abnormalities in COVID-19 patients, typically peaking on the 10th day from symptom onset, in a new study published March 19 in Radiology. The persistence of CT abnormalities through the final stages of disease underscores the need to monitor patients well after discharge.  Discuss
AI differentiates COVID-19 from other pneumonia
March 20, 2020 -- Researchers from China have developed an artificial intelligence (AI) algorithm that accurately detects COVID-19 and differentiates it from community-acquired pneumonia and other lung diseases.

Seattle: COVID-19 patients compromised by comorbidities
March 20, 2020 -- Elderly Seattle area patients who developed COVID-19 in February were made more vulnerable by comorbidities -- and 95% had abnormal imaging findings on admission to the hospital, according to a research letter published online March 19 in JAMA.  Discuss
CT details effect of COVID-19 on pregnant women
March 20, 2020 -- Does COVID-19 have a more devastating effect on pregnant women? Is the disease passed down to newborns after birth? What's the best management strategy for this vulnerable population? Researchers from China addressed these and similar questions in a March 18 study published in the American Journal of Roentgenology.  Discuss
Breast MRI works as presurgical tool
March 20, 2020 -- Breast MRI may improve surgical success for women with breast cancer, according to a study published on March 17 in Radiology. Patients who underwent presurgical MRI had fewer positive surgical margins and repeat surgeries than those who did not.  Discuss
CE-MRI with CT extends life for patients with liver cancer
March 20, 2020 -- Combining CT with contrast-enhanced MRI (CE-MRI) can help extend survival for patients with hepatocellular carcinoma (HCC) by expediting more appropriate treatment decisions, according to a study published in the April issue of Radiology.  Discuss
Ultrasound can be used for patients with COVID-19
March 19, 2020 -- Ultrasound scans show promise for helping to monitor patients with COVID-19, according to a letter published on March 12 in Intensive Care Medicine. The researchers used lung ultrasonography to monitor more than a dozen patients in China with COVID-19 infections.  Discuss
7T MRI sheds new light on risks associated with stroke
March 19, 2020 -- Using 7-tesla MRI, Dutch researchers have identified the three most influential intracranial atherosclerotic risk factors associated with intracranial vessel wall lesions that lead to ischemic stroke, according to a study published in the April issue of Radiology.  Discuss
Women have more chest pain despite less stenosis on CCTA
March 19, 2020 -- Women with coronary artery disease are much more likely to have frequent chest pain than men, despite having less extensive disease on coronary CT angiography (CCTA) and less severe ischemia on stress imaging, according to a study.  Discuss
MRI helps create measures for normal fetal development
March 19, 2020 -- Using MRI, Israeli researchers have established a set of benchmark measurements for fetal facial and cranial structures to help chart development over multiple gestation weeks. Their findings were published on March 12 in the European Journal of Radiology.  Discuss
