Clinical TrialFour-dimensional transcatheter intraarterial perfusion MR imaging for monitoring chemoembolization of hepatocellular carcinoma: preliminary results.
Angiographic endpoints for chemoembolization of hepatocellular carcinoma (HCC) are subjective, and optimal endpoints remain unknown. Transcatheter intraarterial perfusion (TRIP) magnetic resonance (MR) imaging, when performed in a combined MR/interventional radiology (MR-IR) suite, offers an objective method to quantify intraprocedural tumor perfusion changes, but was previously limited to two spatial dimensions. This study prospectively tested the hypothesis that a new volumetric acquisition over time, four-dimensional TRIP MR imaging, can measure HCC perfusion changes during chemoembolization. ⋯ Four-dimensional TRIP MR imaging can successfully measure semiquantitative changes in HCC perfusion during MR-IR-monitored chemoembolization. Future studies may correlate changes in these objective functional parameters with tumor response.

Embolic protection devices in patients with renal artery stenosis with chronic renal insufficiency: a clinical study.
To present clinical outcomes with the use of embolic protection devices (EPDs) and renal artery stents in patients with chronic renal insufficiency (CRI) and renal artery stenosis (RAS). ⋯ Renal artery stent placement combined with the use of a SpideRX or FilterWire EZ device is associated with an good clinical outcome with a reasonable safety profile.

Outcomes of rejected Journal of Vascular and Interventional Radiology manuscripts.
To track the publication fate of rejected Journal of Vascular and Interventional Radiology (JVIR) manuscript submissions. ⋯ A majority of rejected JVIR mauscripts were ultimately published. Rejection of a manuscript by JVIR does not preclude publication.
