The long-term efficacy of radiofrequency ablation (RFA) for the treatment benign thyroid nodules remains unclear. We aimed to evaluate efficacy, emphasizing single-session RFA, and identify factors associated with cases requiring additional RFA sessions achieve a comparable volume reduction rates (VRR). retrospectively evaluated treated between 2008 2018. Treatment at 5- 10-year follow-ups was analyzed. Additionally, subgroup analysis comparing technique such as final VRR, single-...

A study was performed to evaluate the relationship between imaging features and clinical presentation of vertebral artery (VA) dissection. Twenty-two patients with 24 VA dissections at angiography evaluation also underwent computed tomography magnetic resonance imaging. The angiographic patterns dissection were categorized as aneurysmal (n = 10) or steno-occlusive 14). All 10 (10 lesions) pattern had in V4 (intradural) segment presented headache 5), neurologic deficit 2), dizziness altered...

We evaluated the diagnostic role of ultrasonography-guided core needle biopsy (CNB) according to ultrasonography features thyroid nodules that had inconclusive fine-needle aspiration (FNA) results.A total 88 in patients who underwent CNB because previous FNA results were evaluated. The classified into three groups based on findings: Group A, which was suspicious for papillary carcinoma (PTC); B, follicular (Hurthle cell) neoplasm; and C, lymphoma. final diagnoses determined by surgical...

Neointimal hyperplasia is a major complication of endovascular stent placement with consequent in-stent restenosis or occlusion. Improvements in the biocompatibility designs could reduce stent-associated thrombosis and restenosis. We hypothesised that use diamond-like carbon (DLC)-coated nitinol polyethylene glycol (PEG)-DLC-coated formation neointimal hyperplasia, thereby improving patency improved biocompatibility.A total 24 stents were implanted, under general anaesthesia, into iliac...

This study aimed to compare therapeutic efficacy and technical outcomes between adjustable electrode (AE) conventional fixed (FE) for radiofrequency ablation (RFA) of benign thyroid nodules.

<h3>BACKGROUND AND PURPOSE:</h3> Spinal epidural arteriovenous fistulas are rare vascular malformations. We present 13 patients with spinal fistulas, noting the various presenting symptom patterns, imaging findings related to bone involvement, and outcomes. <h3>MATERIALS METHODS:</h3> Among 111 malformations in institutional data base from 1993 2017, thirteen (11.7%) had fistulas. evaluated symptoms findings, including involvement mode of treatment. To assess treatment outcome, we compared...

Disease progression of ankylosing spondylitis has been considered irreversible. However, we report a case spontaneous regression syndesmophyte development following allogeneic peripheral blood stem cell transplantation in patient with acute myeloid leukemia, who was also diagnosed as having spondylitis. To the best our knowledge, this is first presenting partial radiologic syndesmophytes.A 39-year-old man active achieved clinical remission and radiological cervical spine syndesmophytes for...

Purpose: To compare the clinical efficacy, duration of effect, and safety Dysport Botox for patients with essential blepharospasm using functional disability scale. Methods: Patients a confirmed diagnosis who had received (Allergan, USA) from September 2006 to May 2007 were enrolled in this study. We switched (Ipsen, UK) after botulinum effect previous injection disappeared compared efficacy two drugs. used 2.5:1 Dysport:Botox conversion ratio. The drugs treatment was evaluated Results:...

The purpose of this study was to evaluate the utility and efficacy combined low-dose, time-resolved (TR) single-phase high-resolution (HR) contrast-enhanced MRA (CE-MRA) as a pre-angiographic for spinal vascular disease.Seventeen consecutive patients with suspected disease were retrospectively reviewed. All underwent low-dose TR CE-MRA three-dimensional HR at 3 Tesla, followed by conventional digital subtraction angiography (DSA) within 90 days. Six additional DSA treatment follow-up. Spinal...

Purpose: To measure the orbital volume from facial CT scans using a semi-automatic computer program. Methods: Axial and coronal slices of 35 were used to volume. The cross-sectional area was determined each slice semi-automated program (MATLAB 2009a). Next, calculated serial reconstruction cross-sections. Results: measured value in males 26.34 ± 3.09 cm right orbit 26.30 3.21 left axial scans, 26.58 2.76 26.59 2.75 scans. In females, values 23.84 2.29 23.89 2.33 24.06 2.90 24.10 2.82 There...

Objective Endovascular mechanical thrombectomy for the treatment of cerebral venous sinus thrombosis is not always successful. We present our experience using self-expanding stents to facilitate effective recanalization persistent lateral refractory endovascular thrombectomy. Methods Data from patients who underwent acute symptomatic between August 2015 and July 2018 were evaluated. Patient demographics, procedural techniques, devices used follow-up outcomes assessed. Results A total 14...

(1) To find strategies to improve diagnostic performance of ultrasound-guided biopsy intermediate and high suspicion thyroid nodules with macrocalcifications. (2) malignancy rates macrocalcification.From 2018 2022, fine-needle aspiration (FNAB) core needle (CNB) were retrospectively evaluated. Macrocalcifications categorized into three types: intra-nodular, rim entirely calcified. Diagnostic was compared between modes (FNAB vs. CNB) FNAB techniques (to-and-fro whirling). Multivariate...

Purpose: The purpose of this study is to improve the qualitative and quantitative image quality time-resolved angiography with interleaved stochastic trajectories technique (4D-TWIST-MRA) using deep neural network (DNN)-based MR reconstruction software.
