Purpose: This prospective study aims to present the overall success rate, safety and long-term outcome of vibrational angioplasty technique, in the treatment of chronic total femoropopliteal occlusions in our institute.
Purpose: To investigate the ultrasonographic (US) characteristics for nonpalpable thyroid nodules 1–2cm in diameter and to evaluate the guideline for fine needle aspiration (FNA) in terms of US findings.
Objective: To evaluate the local tumor control and survival data after transarterial chemoembolization with different drug combinations in the palliative treatment of patients with liver metastases of gastric cancer.
OBJECTIVE. Interventional radiology tends to involve long procedures (i.e., long fluoroscopic times). Therefore, radiation protection for interventional radiology staff is an important issue. This study describes the occupational radiation dose for interventional radiology staff, especially nurses, to clarify the present annual dose level for interventional radiology nurses.
OBJECTIVE. The purpose of this article is to review the spectrum of early and delayed normal cross-sectional imaging findings after percutaneous radiofrequency ablation of hepatic tumors.
OBJECTIVE. The purpose of this article is to review the spectrum of early and delayed abnormal cross-sectional imaging findings after radiofrequency ablation (RFA) of hepatic tumors.
OBJECTIVE. The objective of our study was to evaluate and describe CT features that may differentiate inferior vena cava (IVC) leiomyosarcomas from primary retroperitoneal masses.
OBJECTIVE. The purpose of this study is to compare the technical success of transjugular intrahepatic portosystemic shunt (TIPS) in transplanted versus nontransplanted livers and to assess the clinical outcome of TIPS in liver transplant recipients.
PURPOSE: We aimed to identify factors that might help differentiate phyllodes tumors from fibroadenomas among cases in which a fibroepithelial breast lesion was diagnosed from core needle biopsy (CNB) under imaging guidance
PURPOSE: This study was performed to assess the safety, efficacy, and clinical outcomes of transjugular intrahepatic portosystemic shunt (TIPS) creation for treatment of medically refractory ascites and to identify prognostic factors for clinical response, morbidity, and mortality.
Hereditary hemorrhagic telangiectasia (HHT), previously known as Osler–Weber–Rendu syndrome, is an autosomal dominant vascular disorder with a variety of clinical manifestations. Mucocutaneous telangiectasias are characteristic of the entity, producing epistaxis and gastrointestinal bleeding that often result in an iron-deficiency anemia. However, life-threatening conditions such as hemorrhage or stroke are usually attributable to the presence of arteriovenous malformations (AVMs) in the pulmonary, cerebral, or hepatic circulations. Pulmonary arteriovenous malformations (PAVMs) are direct communications between the pulmonary arteries and pulmonary veins without an interposed capillary bed; PAVMs thereby serve as a potential conduit for paradoxical embolism that can cause cerebrovascular ischemia or cerebral abscess formation. Also, because PAVMs serve as a physiologic right-to-left shunt, patients can present with high-output heart failure, dyspnea, platypnea, and/or secondary polycythemia. Finally, the friability of the abnormal vasculature often causes PAVMs to increase in size over time or hemorrhage, resulting in hemoptysis or hemothorax. The technical complexity of PAVM embolotherapy and the clinical depth needed to adequately provide long-term follow-up care for the proband and their affected family members makes PAVM management of HHT patients an especially rewarding aspect of clinical interventional radiology.
Purpose: To retrospectively evaluate the results of endovascular therapy of vascular malformations principally treated with ethanol embolization at a single center.
Purpose: To investigate the impact of radioembolization with yttrium-90 resin microspheres on the regulation of angiogenesis through observation of serial changes in a spectrum of angiogenic markers and other cytokines after therapy.
OBJECTIVE. The purpose of this article is to compare the efficacy and complication rates of percutaneous radiofrequency ablation (RFA) and cryoablation in the treatment of renal masses measuring 3.0 cm and smaller.
OBJECTIVE. The objective of our study was to evaluate the diagnostic performance of dual-source dual-energy CT (DECT) in the detection of endoleaks after thoracic endovascular aortic repair for thoracic aortic aneurysm and to investigate if a double-phase (arterial and dual-energy late delayed phase) or a single-phase (dual-energy late delayed phase) acquisition can replace the standard triphasic protocol.
