Purpose: To use network meta-analysis (NMA) to determine the optimal endovascular strategy for management of femoropopliteal peripheral artery disease (PAD) given the lack of multiple prospective randomized trials to guide treatment decisions.
Purpose: To determine the predictors of restenosis, major adverse limb events (MALEs), postoperative death (POD), and all-cause mortality after repeat endovascular treatment of superficial femoral artery (SFA) restenosis.
Purpose: To determine incidence, predictors, and clinical outcomes of postcontrast acute kidney injury (PC-AKI) following renal artery stent placement for atherosclerotic renal artery stenosis.
OBJECTIVE. Colorectal liver metastases (CLM) have a variable response to radioembolization. This may be due at least partly to differences in tumor arterial perfusion. The present study examines whether quantitative measurements of enhancement on preprocedure triphasic CT can be used to predict the response of CLM to radioembolization.
OBJECTIVE. The purpose of the present study is to evaluate Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, tumor attenuation criteria, Choi criteria, and European Organization for Research and Treatment of Cancer (EORTC) PET criteria as measures of response and subsequent predictors of liver progression-free survival (PFS) after radioembolization (RE) of colorectal liver metastases (CLM). The study also assesses interobserver variability for measuring tumor attenuation using a single 2D ROI on a simple PACS workstation.
Radiation exposure caused by scatter radiation from the patient is more intense on the backscatter (i.e., x-ray tube) side than on the forward scatter (i.e., image receptor) side. Placing the x-ray tube underneath the patient decreases the amount of backscatter radiation to which the radiation-sensitive organs of personnel in the fluoroscopy room are exposed.
OBJECTIVE. The purpose of this article is to review the current guidelines and recommendations for percutaneous image-guided treatment of musculoskeletal tumors.
OBJECTIVE. Peripheral nerves are well seen using ultrasound (US) imaging, making US an ideal modality for image-guided nerve injections. This article provides a technical guide for common upper and lower extremity peripheral nerve injections, including the median, ulnar, and radial nerves in the upper extremity and the lateral femoral cutaneous, sciatic, common peroneal, tibial, and sural nerves in the lower extremity.
OBJECTIVE. The purpose of this article is to review currently available tendon treatments, especially those performed with sonographic guidance.
OBJECTIVE. CT plays a crucial role in the evaluation of stable patients with blunt and penetrating trauma in the emergency department. Among the more severe injuries that may occur in penetrating and blunt trauma are those to the inferior vena cava (IVC). The purpose of this study was to evaluate and differentiate the CT findings associated with penetrating versus blunt trauma to the IVC to aid the radiologist in diagnosing IVC injuries.
OBJECTIVE. The aim of this article is to provide an overview of peripheral nerve blocks, the use of peripheral nerve block within and outside interventional radiology, and the complications of peripheral nerve block.
OBJECTIVE. We discuss three health care trends that will have a profound impact on interventional radiology (IR) in the next decade.
OBJECTIVE. Recent articles discussing cases of brain cancer in interventionalists have raised concerns regarding the hazards of occupational exposure to ionizing radiation. We review the basics of radiation dose and the potential radiation effects, particularly as they pertain to the operator. Then we present the data regarding the risk of each type of radiation effect to the fluoroscopy operator and staff, with special attention on cancer induction, radiation-induced cataracts, and the pregnant operator.
OBJECTIVE. The purposes of this article are to review available data regarding the range of protection devices and garments with a focus on eye protection and to summarize techniques for reducing scatter radiation exposure.
OBJECTIVE. The objective of this study is to discuss the use of MRI-guided and MRI-directed prostate biopsy techniques, describe how interventional MRI focal therapies are used for the treatment of prostate cancer, and predict future directions in prostate interventional MRI. The prospect of establishing a center for prostate imaging, diagnosis, and treatment is also discussed.
