Purpose: To demonstrate the feasibility of four-dimensional (4D)–flow magnetic resonance (MR) imaging for noninvasive longitudinal hemodynamic monitoring of hepatic blood flow before and after transjugular intrahepatic portosystemic shunt (TIPS) placement.
Purpose: To characterize vessel occlusion rates and their role in local tumor progression in patients with hepatocellular carcinoma (HCC) who underwent microwave tumor ablation.
Purpose: To evaluate the long-term biochemical, clinical, and recurrence outcomes of radiofrequency (RF) ablation in treating primary aldosteronism due to aldosterone-producing adenoma (APA).
Background: Globally, hepatocellular carcinoma (HCC) is the third most frequent cause of cancer-related mortality. In recent years, transarterial chemoembolization, radiofrequency ablation, and microwave ablation (MWA) have been accepted as treatment modalities for patients with surgically unresectable HCC.
Background & Aims: Sustained virological response following interferon-based antiviral treatment of chronic hepatitis C is associated with decreased long-term risk of hepatocellular carcinoma (HCC) in advanced liver fibrosis. An unexpected high rate of HCC recurrence following antiviral treatment using direct-acting antiviral (DAA) has recently been reported.
Background & Aims: Hepatocellular carcinoma (HCC) represents a serious complication of HCV-related cirrhosis. New direct-acting antivirals (DAA) cure HCV infection in over 90% of patients. The aim of this study was to evaluate the early occurrence and recurrence of HCC in cirrhotic patients treated with DAA.
OBJECTIVE. The purpose of this study was to assess whether implementing emergency department (ED) physician performance feedback reports improves adherence to evidence-based guidelines for use of CT for evaluation of pulmonary embolism (PE) beyond that achieved with clinical decision support (CDS) alone.
OBJECTIVE. The American College of Radiology (ACR) Appropriateness Criteria panel has recommended that patients with prostate cancer who have received treatment undergo imaging only after suspected cancer recurrence. We examined whether local physicians followed this recommendation and what types of imaging examinations were ordered in a cohort of patients with local prostate cancer.
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.
OBJECTIVE. Checklists are tools commonly used to help confirm that certain tasks of a process are completed. Within the health care industry, medical checklists are recognized as a means to improve patient safety.
