Jesi Kim, MD discusses an important article that demonstrates a national increase in utilization of CT scans for trauma-related ED encounters from 2011 to 2018 with a potential relatively greater increased utilization of CT scans in minor traumas.

AI algorithm application to contrast-enhanced chest CT, in comparison with clinical reports, resulted in high negative predictive value and moderate positive predictive value with high number of false positives in incidental pulmonary embolism detection, which raises the question: help or hindrance? Rachana Borkar MBBS, DMRD, DNB discusses potential benefits include second reads, worklist triage in high volume settings, and expedited treatment of incidentally detected pulmonary embolisms.

In this episode, John Do, MD speaks with PAVM expert Michael Taddonio, MD, interventional radiologist and director of the HHT program at the University of California San Diego, to discuss the results of a recently published study in AJR that supports the use of Micro Vascular Plugs as the preferred agent for pulmonary arteriovenous malformations embolotherapy over embolic coils and Amplatzer Plugs.

This podcast with Stephany Mazur, MD and Rebekah Anders, MD covers new literature on multiple architectural distortions (ADs) and the rates of benign, high risk, and malignant pathology on stereotactic biopsy of ADs. Given the higher rate of high-risk lesions in the setting of multiple ADs, biopsy of each site may be warranted.

Aruj Chawla, DO discusses how a CT-based algorithmic approach provides hope that centers with scarce MRI table time availability can provide an alternative characterization with comparable predictive value.

Eymen Ucisik, MD discusses a recently published AJR article aiming to explore the potential uses of MR Elastography in the diagnosis and monitoring of idiopathic intracranial hypertension. 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.

Adrenal adenomas are common due in part to increased utilization of cross-sectional imaging, there is a growing need to evaluate the utility of CT washout for small homogenous adrenal nodules (10 and without history of cancer given the prevalence of malignancy in true incidentalomas is low. 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.

There is not great evidence on what to do when a small lesion of less than 10 mm is detected on surveillance examinations, also known as US-2 subthreshold category. Hyunjoong William Kim, MD discusses a paper that tackles this grey area.

In this podcast, Shambo Guha Roy, MD discusses an AJR article in which the authors tried to evaluate the yield of short-term follow-up CT in demonstrating growth among malignant nodules detected on low dose screening CT.

In this podcast, Mostafa Alabousi, MD discusses a prospective study which compared the performance of contrast-enhancement mammography and breast MRI in assessing neoadjuvant therapy treatment response for patients with breast cancer.
