OBJECTIVE. The purpose of our study was to identify extrahepatic soft tissue mimicking applicator-tract implantation after percutaneous radiofrequency ablation of hepatic malignancy on triple-phase dynamic CT.
OBJECTIVE. The purpose of this article is to retrospectively evaluate radiologically totally implanted central venous access ports (VAPs) of the upper arm in terms of safety, technical feasibility, and device-related complications.
OBJECTIVE. The purpose of this study was to evaluate the safety of pretreatment with gonadotropin-releasing hormone (GnRH) agonists before uterine artery embolization (UAE) of large fibroids.
OBJECTIVE. The purpose of this article is to assess CT enhancement patterns of hepatocellular carcinoma (HCC) within 1 month after transarterial chemoembolization (TACE) using drug-eluting beads and to determine whether enhancement patterns may be useful for predicting local tumor progression.
OBJECTIVE. The goal of this article is to discuss and show the common complications of biliary and gastrointestinal stents as depicted by MDCT in cancer patients. Major complications include stent misplacement or displacement, bleeding, obstruction, perforation, stent fracture or collapse, and infection. This topic encompasses several relevant issues, including interpretative difficulties, therapeutic decisions, and potential malpractice concerns.
Inferior vena cava (IVC) thrombosis is along the clinical spectrum of deep venous thrombosis (DVT), and largely shares the same predisposing clinical factors in Virchow’s triad: hypercoagulability, venous stasis, and vascular injury. There are many causes of IVC thrombosis, including trauma, infection, and compression secondary to retroperitoneal neoplastic processes.1 Intravascular causes, especially foreign bodies such as IVC filters, have been well documented as potential sources for IVC thrombosis. Although the true incidence of IVC thrombosis is unknown, the rate has likely increased with the introduction of permanent or semipermanent intravascular devices, which are thrombogenic.
Purpose: To assess long-term outcomes of stent grafts in patients with symptomatic central venous stenoses and occlusions ipsilateral to hemodialysis grafts or fistulas.
Purpose: To determine the type and frequency of errors during vascular interventional radiology (VIR) and design and implement an intervention to reduce error and improve efficiency in this setting.
Chronic kidney disease (CKD) is a worldwide public health problem. In the United States, between 1988-1994 and 2005-2010, the overall prevalence estimate for CKD, defined by an estimation of glomerular filtration rate <60 ml/min per 1.73m2 or a urine albumin-to-creatinine ratio ≥30 mg/g, rose from 12.3 to 14.0%. In 2010, overall per person per year costs for patients with CKD reached $22,323 for Medicare patients ≥65 years and older, and the overall Medicare expenditure for CKD was $41.0 billion, which consisted of 17% of the total Medicare dollars allocated.
PURPOSE: We aimed to detect possible differences in microwave ablation (MWA) volumes after different fluid preinjections using magnetic resonance imaging (MRI).
PURPOSE: We aimed to evaluate the feasibility and safety of selective arterial embolization for refractory knee hemarthrosis
PURPOSE: We aimed to investigate the potential benefits of three-dimensional rotational angiography (3DRA) compared to two-dimensional (2D) roadmapping to visualize the uterine artery (UA) origins during uterine artery embolization (UAE) procedures.
PURPOSE: We aimed to investigate prostate cancer detection rate of magnetic resonance imaging (MRI)-guided biopsy and to elucidate possible relations to the number of prior negative transrectal ultrasonography (TRUS)-guided biopsies.
PURPOSE: We aimed to estimate the upgrading rate of core-needle biopsy (CNB)-diagnosed papillary breast lesions to atypical or malignant papillary lesions on subsequent surgery.
In the last decade, advances in the diagnosis and treatment of breast cancer have achieved a significant increase in the general and disease-free survival of affected women but have also increased the complexity of therapeutic decisions. The decision-making process requires agreement between the physicians involved in the management of these patients. Radiologists must understand what other physicians expect and inform them about the usefulness of imaging modalities. This review attempts to provide an update on these subjects.
