Prostate Artery Embolization (PAE) with Small Beads for the Treatment of Benign Prostatic Hyperplasia (BPH).

Benign Prostatic Hyperplasia (BPH) is the most frequent cause of Lower Urinary Tract Symptoms (LUTSs) in elderly populations. Minimally invasive treatments of BPH are safe and effective and are gaining popularity among both professionals and patients. Prostate Artery Embolization (PAE) has proven to be effective in Trans-Urethral Resection of the Prostate (TURP) in terms of prostate volume reduction and LUTS relief.

Robotics in Interventional Radiology: Review of Current and Future Applications.

This review is a brief overview of the current status and the potential role of robotics in interventional radiology. Literature published in the last decades, with an emphasis on the last 5 years, was reviewed and the technical developments in robotics and navigational systems using CT-, MR- and US-image guidance were analyzed. Potential benefits and disadvantages of their current and future use were evaluated.

Ablative Therapies for Breast Cancer: State of Art.

Breast cancer (BC) is the most frequently diagnosed malignancy among women. In the past two decades, new technologies and BC screening have led to the diagnosis of smaller and earlier-stage BC (ESBC). Therefore, percutaneous minimally invasive techniques (PMIT) were adopted to treat patients unfit for surgery, women who refuse it, or elderly patients with comorbidities that could make surgery a difficult and life-threatening treatment.

Magnetic Resonance Visibility, Artifacts, and Overall Safety of the Self-Locating Peritoneal Dialysis Catheter with a Tungsten Tip.

Background: The self-locating peritoneal dialysis (PD) catheter, contains a tungsten tip. The effects of magnetic resonance (MR) on the catheter were evaluated, emphasizing its MR signal, artifacts, ferromagnetism, and possible heating production during the MR sequences.

Methods: The catheter was studied in an ex vivo model using a 1.

Etiologic reclassification of cryptogenic stroke after implantable cardiac monitoring and computed tomography angiography re-assessment.

Introduction: Different mechanisms may underlie cryptogenic stroke, including subclinical atrial fibrillation (AF), nonstenotic carotid plaques (NCP), and aortic arch atherosclerosis (AAA). In a cohort of cryptogenic stroke patients, we aimed to: (1) evaluate the prevalence of subclinical AF, NCP, and AAA, and reclassify the etiology accordingly; (2) compare the clinical features of patients with reclassified etiology with those with confirmed cryptogenic stroke.

Methods: Data of patients hospitalized for cryptogenic stroke between January 2018 and February 2021 were retrospectively analyzed.

Effects of Prone Position on Lung Recruitment and Ventilation-Perfusion Matching in Patients With COVID-19 Acute Respiratory Distress Syndrome: A Combined CT Scan/Electrical Impedance Tomography Study.

Objectives: Prone positioning allows to improve oxygenation and decrease mortality rate in COVID-19-associated acute respiratory distress syndrome (C-ARDS). However, the mechanisms leading to these effects are not fully understood. The aim of this study is to assess the physiologic effects of pronation by the means of CT scan and electrical impedance tomography (EIT).

Chest X-ray findings in a large cohort of 1117 patients with SARS-CoV-2 infection: a multicenter study during COVID-19 outbreak in Italy.

To describe radiographic key patterns on Chest X-ray (CXR) in patients with SARS-CoV-2 infection, assessing the prevalence of radiographic signs of interstitial pneumonia. To evaluate pattern variation between a baseline and a follow-up CXR. 1117 patients tested positive for SARS-CoV-2 infection were retrospectively enrolled from four centers in Lombardy region.

Myths and facts about artificial intelligence: why machine- and deep-learning will not replace interventional radiologists.

Artificial intelligence (AI) is revolutionizing healthcare and transforming the clinical practice of physicians across the world. Radiology has a strong affinity for machine learning and is at the forefront of the paradigm shift, as machines compete with humans for cognitive abilities. AI is a computer science simulation of the human mind that utilizes algorithms based on collective human knowledge and the best available evidence to process various forms of inputs and deliver desired outcomes, such as clinical diagnoses and optimal treatment options.

Endovascular treatment of a ruptured pulmonary artery aneurysm in a patient with Behçet's disease using the Amplatzer Vascular Plug 4.

A pulmonary artery aneurysm is a common manifestation and the leading cause of mortality in Behçet's disease. We describe a case of spontaneous rupture of a pulmonary artery aneurysm that, due to the inadequacy of medical therapy and the disadvantages of surgery, became the ideal candidate for endovascular management and was successfully performed by using the Amplatzer Vascular Plug 4.

Plasma-mediated radiofrequency ablation followed by percutaneous cementoplasty under fluoro-CT guidance: a case report.

We report a case of a 81-year-old Caucasian man with colorectal carcinoma, treated by surgery in 1998, referred for palliative treatment of a refractory painful caused by osteolytic metastases of 2.5 cm in back-upper ilium spine. Plasma-mediated radiofrequency ablation was performed under conscious sedation, using Fluoroscopic Computer Tomography guidance.

Percutaneous radiofrequency thermal ablation of renal cell carcinoma: is it possible a day-hospital treatment?

Purpose: The aim of this study is to evaluate the feasibility of the procedure in day-hospital and discuss prognostic factors, efficacy and complications of percutaneous radiofrequency ablation in the treatment of renal cell carcinoma.

Materials And Methods: Between January 2003 and August 2008, 26 patients (mean age 79, range 70-87 years, 15 men and 11 women) affected by 27 kidney tumoral lesions, 25 RCC and two renal oncocitome (one patient was affected by two RCC), undergo 29 treatments of RFA (three patients underwent two treatments due to residual tumor at the CT performed 1 month after the first treatment). Three out of 26 patients had only one kidney due to progressed nephrectomy because of RCC; three/26 patients were carriers of oncological comorbidity while four/26 patients were carriers of medical comorbidity.

Radiofrequency thermal ablation for pain control in patients with single painful bone metastasis from hepatocellular carcinoma.

Objective: The aim of this study was to assess the safety and the efficacy of radiofrequency thermal ablation (RFA) for pain relief and analgesics use reduction in two patients with painful bone metastases from hepatocellular carcinoma (HCC).

Materials And Methods: Two patients with lytic metastases from HCC located at the left superior ileo-pubic branch and at the middle arch of VII rib, performed RFA displacing a LeVeen Needle (3.5 and 4.

Emergency percutaneous treatment in surgical bile duct injury.

The aim of this study is to evaluate the efficacy of emergency percutaneous treatment in patients with surgical bile duct injury (SBDI). From May 2004 to May 2007, 11 patients (five men, six women; age range 26-80 years; mean age 58 years) with a critical clinical picture (severe jaundice, bile peritonitis, septic state) due to SBDI secondary to surgical or laparoscopic procedures were treated by percutaneous procedures.
