PURPOSE: To report results of renal denervation (RDN) with the first catheter-based, non-balloon occlusion ultrasonic system in patients with resistant hypertension. MATERIALS AND METHODS: In a multicenter, single-arm trial, 39 patients with resistant hypertension (defined as uncontrolled hypertension while taking ≥ 3 antihypertensive medications) were treated. The cohort consisted of 4 groups: severe resistant hypertension (office systolic blood pressure [OSBP] ≥ 160 mm Hg) treated with a unidirectional catheter (group 1; n = 14); severe resistant hypertension treated with a multidirectional catheter (group 2; n = 18); moderate resistant hypertension (OSBP 140-159 mm Hg) treated with a multidirectional catheter (group 3; n = 5); and recurrent severe resistant hypertension, after an initial response to RF RDN (group 4; n = 2)...

PURPOSE: To assess feasibility and efficacy of CKD-516, a vascular disrupting agent, in transarterial chemoembolization in a liver tumor model. MATERIALS AND METHODS: A VX2 carcinoma strain was implanted in rabbit liver (n = 40) and incubated for 2 weeks. After confirmation of tumor growth using computed tomography, transarterial chemoembolization was performed. CKD-516 was dissolved in ethiodized oil, and animals were allocated to 4 treatment groups (n = 10 in each): group A, ethiodized oil; group B, ethiodized oil/CKD-516; group C, ethiodized oil + doxorubicin; group D, ethiodized oil/CKD-516 + doxorubicin...

PURPOSE: To evaluate clinical outcomes and possible MR imaging predictors of clinical success after prostatic artery embolization (PAE) with 250-μm hydrogel particles. MATERIALS AND METHODS: During a span of 1.5 years, 30 patients with moderate to severe lower urinary tract symptoms were included in a prospective, nonrandomized study. Embolization of at least one prostatic artery was considered as technical success. International Prostate Symptom Score (IPSS), quality of life (QOL), peak urinary flow rate (Qmax ), residual urine volume, prostate volume, prostate-specific antigen level, and International Index of Erectile Function (IIEF) were recorded at baseline and at 1, 3, and 6 months after PAE...

PURPOSE: To evaluate treatment outcomes with percutaneous cryoablation (PCA) based on renal cell carcinoma (RCC) histology. METHODS AND MATERIALS: Patients treated with PCA for a solitary, sporadic stage T1a RCC from 2003 to 2016 were identified from a single institution's renal ablation registry. Patients with multiple tumors, history of RCC, or genetic syndromes associated with RCC (n = 60); no specific RCC subtype determined from core biopsy (n = 66); RCC subtype other than clear-cell or papillary (n = 7); or less than 3 mo of follow-up imaging (n = 5) were excluded...

PURPOSE: This study used the Oncopig Cancer Model (OCM) to develop alcohol-induced fibrosis in a porcine model capable of developing hepatocellular carcinoma. MATERIALS AND METHODS: Liver injury was induced in 8-week-old Oncopigs (n = 10) via hepatic transarterial infusion of 0.75 mL/kg ethanol-ethiodized oil (1:3 v/v). Feasibility was assessed in an initial Oncopig cohort (n = 5) by histologic analysis at 8 weeks after induction, and METAVIR results were compared to age- and sex-matched healthy controls (n = 5)...

PURPOSE: To evaluate the efficacy and safety of thrombectomy using myocardial biopsy forceps for the treatment of acute limb ischemia (ALI). MATERIALS AND METHODS: A retrospective review of 11 ALI patients (12 affected limbs, 18 affected vessels) who underwent thrombectomy using biopsy forceps between November 2011 and April 2016 was performed. Of the 12 affected limbs, 2 limbs had stent thrombosis, 1 limb had thrombotic occlusion at a de novo stenosis site, and 9 limbs had embolic ALI...

PURPOSE: To employ bioluminescence imaging (BLI) as a quantitative imaging biomarker to assess preclinical evaluation of cryoablation in a murine model. MATERIALS AND METHODS: In vitro, Colon26-Luc (C26-Luc) cells were seeded at 6 different concentrations in 35-mm dishes. These were divided into 6 groups: group 0 (G0), a control group without treatment; and groups 1-5 (G1-G5) according to the number of freeze-thaw cycles, with each cycle consisting of freezing at -80°C for 10 min followed by thawing at room temperature for 5 minutes...

PURPOSE: To assess the feasibility of validating the position of the needle in groin lymph nodes using injection of ultrasound (US) contrast prior to magnetic resonance (MR) lymphangiography. MATERIALS AND METHODS: In 28 patients (average age, 52 y; 15 women, 13 men), 25G needles were placed in bilateral groin lymph nodes using US guidance outside the MR suite. The confirmation of the position of the needles in lymph nodes and efferent lymphatic flow was performed by injecting 1 mL of the US contrast agent (Lumason) mixed with 2 mL of lidocaine and observing contrast enhancement of the efferent lymphatic ducts leading to the pelvis from the lymph node...

PURPOSE: To analyze whether primary venous stent placement into 1 dominant inflow vein peripheral to the common femoral vein (CFV) confluence is feasible. MATERIALS AND METHODS: Retrospective review was performed of 14 consecutive patients who underwent primary venous stent placement into veins peripheral to the CFV between 2013 and 2016. Mean patient age was 49 years; 6 (43%) patients were women. All patients had successful deep venous stent placement with brisk contrast flow through the stent...

PURPOSE: To evaluate the safety and efficacy of iodine-125 (125 I) seed strand implantation in combination with transarterial chemoembolization for the treatment of hepatitis B-related unresectable hepatocellular carcinoma (HCC) with portal vein invasion. MATERIALS AND METHODS: From January 2013 to June 2016, 76 HCC patients with type II tumor thrombus were included in this single-center retrospective study. Twenty patients underwent 125 I seed strand implantation combined with transarterial chemoembolization (group A; n = 20), while 56 patients underwent transarterial chemoembolization alone (group B; n = 56)...

Seven patients with pulmonary arteriovenous malformations (PAVMs) not well suited to coil and/or plug treatment were treated with expanded polytetrafluoroethylene-covered stents. Mean diameter of treated arteries was 6 mm. Complete technical success was achieved in 7 of 8 PAVMs, 6 using only covered stents and 1 using both a covered and a bare stent owing to endoleak. In 1 patient, the parent vessel was sacrificed after identification of additional feeding vessels following stent graft placement. In 6 patients with median imaging follow-up of 8 months (range, 1-121 months), all stent grafts were patent, and all treated PAVMs were completely excluded without persistence...

Current imaging technologies are capable of acquiring volumetric data, but they are limited by the flat 2-dimensional representation of complex 3-dimensional data. This pictorial report illustrates the potential role of interactive virtual reality (VR) that enables physicians to visualize and interact with image data as if they were real physical objects. Increasing availability of tools that make the VR environment a possibility could potentially be valuable in the interventional radiology suite.
