Full article: https://www.ajronline.org/doi/abs/10.2214/AJR.21.27147 Early diagnosis and treatment of pulmonary hypertension are crucial to prevent chronic progression and a poor prognosis. The nonspecific presenting symptoms and need for right heart catheterization may contribute to a delay in diagnosis. In this episode, Sara Tedla MD, discusses a recently published study in AJR, which evaluates the utility of cardiac chamber volumetric measurements based on non-gated CT pulmonary angiography and the updated 2018 pulmonary hypertension criteria.

This study incentivizes the use of automated MR Elastography to screen for hepatic fibrosis in nonalcoholic hepatosteatotitis.

Liu, MD discusses an article that assesses the utility of preoperative shear wave elastography measurements of the supraspinatus muscle to predict successful rotator cuff repair, including comparison with MRI-based measures.

Liwei Jiang, MD, discusses a new study that links cirrhosis with the severity of post-embolization syndrome after bland hepatic artery embolization. The findings may help select patients for early discharge after the procedure.

Clinical providers, including radiologists, may find diagnostic value to consider incorporating whole-spine MRI in cases of possible abusive head trauma as many spinal injuries are localized to the thoracolumbar spine, in addition to the cervical spine.

Awareness of these factors are opportunities for improved practices and quality assurance measures.

This study supports the widespread utilization of 1.5-T MRI to further explore the clinical utility of a novel MR marker in multiple sclerosis patients.

The conclusions include that a low-energy mammographic finding with associated enhancement, or a finding with sonographic or MRI correlate, predicts a true-positive result. Calcifications with associated enhancement had a high malignancy rate. Nonetheless, half of true-positive lesions enhanced on iodine images without a mammographic finding on low-energy images. These observations inform radiologists' management of abnormalities detected on screening CEDM.
