It is relevant for the radiology audience since MR elastography may potentially provide a noninvasive alternative to lumbar puncture in the evaluation of the intracranial pressure, although further studies are needed to support this proposal.

Mohanned Alnammi, MD discusses an article that found evaluating true incidentalomas with HU >10 with CT washout and showed suboptimal diagnostic performance and that the 60% washout threshold may be of limited utility in those without a history of cancer.

Hyunjoong William Kim, MD discusses a paper that tackles this grey area.

Abdul Khan, MD, discusses a recently published AJR article in which investigators evaluated the diagnostic performance of biopsy of occult osseous lesions and analyze the various malignant and benign diagnosis.

Alexandra Millet, MD discusses a new study that observed a prolonged duration to resolution of unilateral ipsilateral axillary lymphadenopathy suspected to be related to COVID 19 vaccination. Administration of the Moderna vaccine, receipt of a second vaccine dose after the initial lymphadenopathy presentation, and greater cortical thickness at initial presentation were independently associated with a longer time to resolution following presentation. The findings support a follow up interval of at least 12 weeks for suspected vaccination-related lymphadenopathy as well as not delaying screening mammography due to recent vaccination.

This validation study bolsters the value of multiparametric MRI to predict pathologic diagnosis of incidentally detected renal cell carcinoma.

By more accurately reporting these scores, large groups of patients may greater benefit from preventative treatment of coronary disease.
