Overview
About 10 years ago, the clinical usefulness of mechanical thrombectomy (MT) for acute ischemic stroke (AIS) was proven. This revolutionary event significantly changed clinical practice in neuroimaging during the acute stage. In the early period after its introduction in 2014, "Time is brain" was the most common keyword in the treatment strategy of AIS. Shortening of preoperative examination time and rapid decision making for MT was required.
To overcome this issue, many studies have been conducted to develop sophisticated MRI protocols for AIS, and the role of brain MRI has drastically changed throughout the previous decade. As a result, the era of "Imaging is brain" has arrived. Additionally, MRI is already not considered to delay the treatment of AIS.
In line with these transitions in imaging strategies, we have been striving for the past decade to improve our MRI protocols and develop new rapid sequences for AIS. In this talk, we would like to describe the role and knowledge of MRI and introduce our 7-min MRI protocol for acute ischemic stroke.

Target Audience
Radiographers, Physicians, Radiologists, and Scientists.

Educational Objectives
As a result of attending this course, participants should be able to:
Understand the latest advancements in MRI technology and acquire skills that can be immediately applied in clinical practice;
Understand the solutions to the challenges faced by Japanese radiological technologists; and
Understand the role and impact of Japanese radiological technologists in the international innovation of diagnostic technologies.

10:50		10 Years Review, MRI for Acute Ischemic Stroke & Our Works View Presentation Video Oura Daisuke, Riku Ihara, Takumi Yokohama, Yoshimasa Niiya Impact: The 7min-Acute ischemic stroke protocol including ASL, black blood image, chest MRA.
11:20		What is Needed for a Comfortable Musculoskeletal MRI Examination? View Presentation Video Yoshihiro Akatsuka Impact: Musculoskeletal MRI requires high-resolution images, but motion artifacts often degrade image quality. Shorter musculoskeletal MRI exam times improve patient comfort and reduce motion artifacts. I would like to talk about patient positioning skills and exam planning.
