This month’s journal-based CME article is titled "CT foot perfusion examination for evaluation of percutaneous transluminal angioplasty outcome in patients with critical limb ischemia: A feasibility study."
In this study, the authors investigate foot perfusion in patients with critical limb ischemia (CLI) using quantitative perfusion multidetector-row computed tomography and estimate perfusion parameters changes before and after percutaneous transluminal angioplasty (PTA).This study provides valuable data on CTFP, its reproducibility and is a technique which may be useful for the estimation of PTA outcomes. Restitution of perfusion parameters after successful revascularization can help identify patients with successful clinical outcomes from those who require amputation.
This program is designed to meet the educational needs of interventional radiologists, vascular surgeons, vascular medicine, cardiologists, nurses, techs, and trainees at all levels with special interest in peripheral arterial disease.
To receive CME credit for this journal-based CME activity, participants must read the journal article and score 75% or better on the post test. Participants will have three opportunities to score 75% or better.
After participating in this journal-based CME activity, learners should be able to:
Describe the changes in perfusion parameters before and after technically successful PTA.
Identify the differences in perfusion parameter changes in patients with clinical improvement after PTA (Group A) compared to patients without any clinical improvement despite PTA (Group B).
Understand the sensitivity and specificity of perfusion parameters to predict the need for amputation.

This activity has been planned and implemented in accordance with the Essentials and Standards of the Accreditation Council for Continuing Medical Education (ACCME).
The Society of Interventional Radiology (SIR) is accredited by the ACCME to provide continuing medical education for physicians. SIR designates this education activity for a maximum of 1 AMA PRA Category 1 Credit™. Physicians should claim only the credit commensurate with the extent of their participation in the activity.
This program is approved for 1 self-assessment CME credit (SA-CME) by the Society of Interventional Radiology (SIR) - approved March 1, 2019. SIR is awarded Deemed Status by the American Board of Radiology (ABR). The SA-CME credit offered for this enduring activity meets the ABR’s criteria for self-assessment toward the purpose of fulfilling requirements in the ABR Maintenance of Certification (MOC) Program.
