PURPOSE: Transarterial chemoembolization (TACE) is an established treatment for intermediate stage hepatocellular carcinoma (HCC). The aim of this retrospective study was to evaluate the power of lesion vascularization criteria based on computed tomography for prognosis of overall survival before initiation of treatment.
PURPOSE: We aimed to evaluate the safety and effectiveness of fluoroscopy-guided gastroduodenal metallic stent placement with different approaches in malignant obstruction.
PURPOSE: Transjugular intrahepatic portosystemic shunt (TIPS) creation is used to treat portal hypertension complications. Often the most challenging and time-consuming step in the procedure is the portal vein (PV) puncture. TIPS procedures are associated with prolonged fluoroscopy time and high patient radiation exposures. We measured the impact of transabdominal ultrasound guidance for PV puncture on duration of fluoroscopy time and dose.
OBJECTIVE. The purpose of this article is to describe the indications for and approach to catheter-based treatment of acute venous thromboembolism (VTE).
OBJECTIVE. The purpose of this study was to examine risks of cancer incidence and mortality among U.S. radiation technologists performing or assisting with fluoroscopically guided interventional procedures.
OBJECTIVE. The purpose of this study was to compare manual and battery-powered bone biopsy systems for diagnostic yield and procedural factors during core needle biopsy of sclerotic bone lesions.
OBJECTIVE. Palpable subcutaneous masses present in various shapes and sizes in the pediatric population and, accordingly, represent a variety of underlying causes. Lymphatic and venous malformations are among the most common pediatric subcutaneous lesions. However, there are congenital and acquired, as well as benign and malignant, soft-tissue masses that can mimic them clinically and at imaging.
OBJECTIVE. The purpose of this article is to review the unusual clinical and radiographic features of venous malformations that can give rise to diagnostic confusion. Entities that can have overlapping clinical and imaging features with venous malformations are also reviewed.
OBJECTIVE. The purpose of this study was to evaluate the diagnostic accuracy and safety of ultrasound (US)–guided transvaginal core biopsy of pelvic masses.
OBJECTIVE. Given the recent classification of hepatic adenoma (HA) into subtypes and recognition of imperfect specificity of MRI to differentiate HA from focal nodular hyperplasia (FNH), there is a resurgent interest in the role of biopsy to diagnose HA. The purpose of this study was to determine the safety and outcomes of biopsy of HAs.
OBJECTIVE. The purpose of this study is to investigate when repeat ultrasound (US)–guided fine-needle aspiration (FNA) for thyroid nodules 10 mm or larger with initial nondiagnostic results due to inadequate or unsatisfactory specimen could be performed.
OBJECTIVE. The objective of our study was to assess the incidence of contrast-induced nephropathy (CIN), dialysis, and graft loss after direct intraarterial infusion of iodine-based contrast medium (CM) in renal allograft recipients.
Purpose: To evaluate the safety and efficacy of transcatheter arterial embolization with N-butyl cyanoacrylate (NBCA) for the treatment of gastrointestinal (GI) bleeding via a meta-analysis of published studies.
Purpose: To determine all-cause readmission rates for 12 IR procedures and association of time to readmission with risk-adjusted 90-day mortality.
Purpose: To determine if coil embolization is a safe adjunctive measure to prevent nontarget embolization during prostatic artery embolization (PAE).
