AI can be used to expand the role of chest X-ray imaging in COVID-19 diagnosis

According to a recent report by Johns Hopkins Medicine researchers, artificial intelligence (AI) should be used to expand the role of chest X-ray imaging -- using computed tomography, or CT -- in diagnosing and assessing coronavirus infection so that it can be more than just a means of screening for signs of COVID-19 in a patient's lungs.

Guidance for assessing bone density and microarchitecture in vivo with HR-pQCT

The use of high-resolution peripheral quantitative computed tomography (HR-pQCT) to assess bone microarchitecture in clinical studies has continued to grow rapidly. Thus, there is an urgent need for guidance and consensus on the methods for and reporting of HR-pQCT imaging so that different studies can be compared to each other.

Anesthetic drug Ketamine uses serotonin receptors to relieve depression

Ketamine is a drug used to induce general anesthesia. It has also been found to act rapidly to relieve depression that has failed to respond to two other rounds of medication. A new study published in the journal Translational Psychiatry in May 2020 reports the mechanism of action of the drug, which was hitherto unknown. This could help find new ways to treat this debilitating and sometimes fatal condition.
