Article Synopsis
- The study assessed how well pre-trained deep learning models can grade hepatic steatosis (HS) in patients with Non-Alcoholic Fatty Liver Disease (NAFLD) using ultrasound images of the liver and kidney.
- A total of 112 NAFLD patients underwent ultrasound examinations, and various deep learning models (like InceptionV3 and DenseNet201) were trained and tested on cropped images that were either augmented or not.
- The models showed high accuracy in HS grading, particularly DenseNet201 with augmented data, which may serve as a useful tool for diagnosing and grading NAFLD alongside radiologist assessments.
Background Digital subtraction angiography and thrill palpation demonstrate limitations when used to assess the outcomes of angioplasty in autologous arteriovenous fistulas (AVFs). Purpose To investigate a new functional quantifiable index of successful angioplasty for failing AVFs using intraprocedural percutaneous US volume flow (VF) measurements. Materials and Methods This prospective, multicenter, single-arm, cohort clinical trial included consecutive patients with indications for fluoroscopically guided balloon angioplasty due to AVF dysfunction between June 2020 and May 2022.

- Intracranial atherosclerotic disease (ICAD) is a major cause of ischemic stroke globally, with rising detection rates across various racial and ethnic groups, shifting our understanding of its epidemiology.
- The disease is characterized by the buildup of plaques in major intracranial arteries, with diagnosis relying on the degree of luminal narrowing, which can now be detected earlier using advanced imaging techniques like high-resolution vessel wall MRI.
- Recent studies show that while historically certain racial groups had higher ICAD prevalence, there is an increasing recognition of the condition among White patients, raising the need for tailored management strategies that address risk factors and emerging treatments.
Vascular access is the initial, very important, step of endovascular procedures. Various access sites include the common femoral artery, brachial artery, radial artery, popliteal artery, and distal tibial vessels (pedal arteries). Successful arterial access requires advanced knowledge of anatomy, as well as proper training and experience.

When it becomes necessary to cover the supra-aortic vessels, maintaining blood supply through the supra-aortic branches can be achieved by performing in situ needle fenestration. We present a case of a 65-year-old man with a type B aortic dissection that extended from the origin of the left subclavian artery.
