This retrospective study suggests that in patients with HCC tumours of ≥ 3 cm, treatment with TACE + SBRT provides a survival advantage over treatment with only TACE. Confirmation of this observation requires that the concept be tested in a prospective, randomized clinical trial.
The novel coronavirus disease 2019 (COVID-19) has had a major impact on the education of trainees in the radiology environment. The precipitous drop in patient volumes and sequestering of faculty and trainees to maintain social distancing affects experiential learning. The shift of nearly all teaching settings to a virtual environment has been challenging but may also allow more interaction during teaching sessions than traditional readout sessions or didactic lectures. Faculty development is key in ensuring competence and confidence in this new environment. Recruitment of trainees using a virtual platform will require communication of opportunities as well as the culture of the department and institution as well as the community. Delay of the board examinations has caused angst as well as disruption of the timing of clinical rotations but may ultimately result in a shift of how the examinations are administered. The exceptional disruption of the COVID-19 pandemic allows us to reconsider how the educational aspects of imaging can emerge as improved in the years to come.
Contrast-enhanced US has a high likelihood of definitively classifying a renal lesion that is indeterminate by computed tomography, magnetic resonance imaging, or conventional US.
Doppler ultrasound plays an important role in the postoperative management of hepatic transplantation, by enabling early detection and treatment of various vascular complications. This article describes the normal Doppler findings following liver transplantation and reviews the imaging appearances of various vascular complications associated with it. The article also discusses transient waveform abnormalities, often seen on a post-transplant Doppler examination, and the importance of differentiating them from findings suggestive of ominous vascular complications.
Nonenhancing renal cysts, including hyperattenuating cysts, can be discriminated from enhancing masses on effective atomic number maps generated from dual-energy contrast-enhanced CT data. This technique may be of clinical usefulness when a CT protocol for comprehensive assessment of renal masses is not available.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
