PURPOSE: This study aimed to evaluate the safety and effectiveness of the combination of DEM-TACE with chemotherapy in treating unresectable intrahepatic cholangiocarcinoma (ICC). MATERIALS AND METHODS: 70 patients diagnosed with unresectable ICC between Jan. 2016 and Dec. 2020 were retrospectively included in this study. Of these, 39 patients received DEM-TACE and first-line chemotherapy (D-TACE+Chemo group) and 31 received chemotherapy alone (Chemo group). Propensity score matching (PSM) was performed to reduce selection bias between the D-TACE+Chemo and the Chemo groups...

PURPOSE: To assess the technical feasibility and safety of image-guided percutaneous biphasic monopolar pulsed electric field (PEF) ablation of primary and metastatic tumors. METHODS AND METHODS: With IRB approval and HIPAA compliance, this retrospective, single-institution study cohort of 17 patients (mean age: 53.5 years, range: 20 - 94 years) with overall progressive disease underwent 26 PEF ablation procedures for 30 metastatic (90%) and primary (10%) target lesions in the thorax (n=20), abdomen (n=7), and head and neck (n=3)...

PURPOSE: To determine adrenal vein sampling (AVS) and post-adrenalectomy outcomes in patients with a non-suppressed plasma renin activity (PRA) and elevated aldosterone-to-renin ratio (ARR). MATERIALS AND METHODS: The study sample included 23 patients with an ARR > 20 and PRA > 1 ng/mL/h ("non-suppressed group") and 69 patients with an ARR > 20 and PRA < 0.6 ng/ml/h ("suppressed group") who underwent AVS from 2006-2023. Data regarding baseline clinical characteristics, AVS results, and outcomes after adrenalectomy were analyzed...

PURPOSE: To evaluate the clinical and imaging outcome of aneurysmal bone cysts (ABC) in children using percutaneous cryoablation as the sole treatment. MATERIAL AND METHODS: This retrospective study included 7 children mean age 8.7 years (range 3.0 to 11.9 years) who received at least one cryoablation for ABC. Cryoablation needles were placed and guided by computer tomography (CT). Imaging follow-up and clinical examination were performed by radiography 1 and 6 months and magnetic resonance imaging (MRI) 3 and 12 months after the procedure...

PURPOSE: To investigate the effect of patient and tumor-specific characteristics on the size of immediate phase lung microwave ablation (MWA) zone and establish a prediction model. METHODS AND MATERIALS: This IRB-approved, HIPAA compliant cohort included 164 lesions from 99 patients who underwent CT-guided lung MWA and the two-dimensional elliptical ground-glass opacity ablation zone was measured. Duration, maximum temperature, tumor depth, presence of emphysema, history of ipsilateral lung ablation, surgery, and radiation were recorded...

Realistic simulation models for interventional radiology procedures are limited, including for placement of double-J stents (DJS). Utilizing a porcine kidney and empty saline bag (bladder), an ex-vivo model aiming to improve operator's knowledge and confidence in performing a DJS procedure was developed. Six faculty and fourteen trainees successfully operated on the model. Mean results for faculty vs. trainees are as follows: 2.2 ± 1.5 vs 2.4 ± 1.9 puncture attempts to access collecting system (p = 0...

PURPOSE: The aim of this study was to use calculated aldosterone concentration in the right adrenal vein (RAV) (cAldoRAV ) for identifying the dominant side of aldosterone secretion in patients with primary aldosteronism undergoing adrenocorticotropic hormone-stimulated adrenal venous sampling (AVS). MATERIALS AND METHODS: Patients with primary aldosteronism who had successful AVS (selectivity index > 3) were studied. Based on the assumption that cortisol production from both adrenal glands is equal, aldosterone concentration in the RAV was calculated by using the data from left adrenal vein (LAV) and inferior vena cava...

PURPOSE: This study aimed to compare the safety and effectiveness N-butyl cyanoacrylate (NBCA)-lipiodol mixture (NL) and NBCA-lipiodol-ethanol mixture (NLE) embolization for Type II endoleak (T2EL) after endovascular aortic repair (EVAR). MATERIALS AND METHODS: This study included 32 patients with 49 procedures who underwent T2EL embolization between January 2008 and June 2022. Cases with no follow-up after embolization, technical failure, treatment with coil only, T1EL at the embolization, and re-embolization were excluded...

This retrospective study evaluates the feasibility, safety, and short-term efficacy of PAE using n-BCA glue embolization in 244 patients from June 2022 through May 2024. Technical success, defined as bilateral glue embolization, was achieved in 95% of cases. The median fluoroscopy time was 22.2 (IQR: 17.1 - 30.0) minutes, and the median radiation dose was 753 (IQR: 417 - 1559) mGy. Compared to baseline, statistically significant improvements were observed at 7.1 weeks for the IPSS (9.5 ± 6.0 [SD] vs. 20...

PURPOSE: To compare the efficacy of two track sealing techniques following CT-guided lung biopsy, using either gelatin sponge slurry (GSS) or saline to reduce the rate of post-biopsy pneumothorax. MATERIALS AND METHODS: In this prospective study, patients referred for a CT-guided lung biopsy, in whom the needle would pass through aerated lung, were randomly assigned to receive either GSS or saline track sealing technique in a 1:1 ratio. All biopsies were performed using a 19-gauge coaxial needle in a tertiary hospital by one of four interventional radiologists with varying levels of experience...

This brief report reviews the clinical, procedural, and imaging data of seven patients with p.Arg4810Lys variant of the ring finger protein 213 gene (RNF213)-related peripheral pulmonary arterial stenosis (PPAS) who underwent percutaneous transluminal pulmonary angioplasties (PTPAs) for demographics, clinical presentation, indications for BPA, and procedural and clinical outcomes. During median follow-up of 64.4 months since the first confirmed diagnosis, PTPA was performed for 62 segmental pulmonary arteries with 38 sessions of the procedure in seven patients...

PURPOSE: This study aimed to validate the correlation between the Global Limb Anatomic Staging System (GLASS) and primary limb-based patency (LBP) and to identify the risk factors associated with LBP loss. MATERIALS AND METHODS: A single-center retrospective analysis was performed on patients with chronic limb-threatening ischemia (CLTI) who underwent endovascular therapy (EVT) between January 2018 and May 2022. All lesions were categorized into three groups (GLASS I, II, and III)...

PURPOSE: To utilize voxel-based dosimetry following radiation segmentectomy to understand microsphere distribution and validate current literature regarding radiologic and pathologic outcomes. METHODS: A retrospective, single-center analysis of solitary HCC patients (n=56) treated with Y90 radiation segmentectomy with glass microspheres (TheraSphere; Boston Scientific, Marlborough, MA, USA) from 2020 to 2022 was performed. Post-treatment voxel-based dosimetry was evaluated using Mirada DBx Build 1...

PURPOSE: To assess immunogenic effects in unembolized contralateral tumor after single lobar Y90-radioembolization (SIRT) of colorectal liver metastases(CRLM). MATERIAL AND METHODS: The analysis comprised 10 patients with microsatellite stable (MSS) CRLM scheduled for staged treatment in the prospective BLINDED trial. Eligibility criteria included bilobar metastatic disease with >5 lesions without any treatment within 3 weeks. Baseline biopsy was followed by initial SIRT treatment of one liver lobe, followed by a second biopsy of yet untreated tumors in the other liver lobe at a median of 13 (4-49) days immediately prior to second treatment...

PURPOSE: To evaluate the feasibility of intraoperative neurophysiological monitoring (IONM) during MRI-guided ablations and identify strategies to reduce IONM electrode radiofrequency (RF)-heating during MRI. MATERIALS AND METHODS: Ex vivo experiments with a porcine tissue phantom simulating a typical high RF-heating risk IONM setup during an MRI-guided ablation procedure on the shoulder were performed on a 1.5 T scanner. Mutual interference between MRI and IONM was evaluated...
