안녕하세요 영상의학과 이지은입니다. 2020년 겨울부터 쓰기 시작한 제 책이 드디어 출간되었습니다. 이미지가 워낙 많고, 동영상 QR코드가 수 백개이다보니 1년이 넘게 걸렸네요. (군자출판사와 제가 13차 수정까지 했더라구요) 제 책을 기다려 주신 선생님들에게 생각보다 오래 걸려서 죄송하다는 말씀을 드리고 싶습니다. 제 책의 여러 판매처 중 몇 군데만 링크를 아래 달아두겠습니다. 부족할 수 있지만, 최선을 다한 책이니 많은 관심 가져주시면 감사드리겠습니다 ^^ MRI 자신감 키우기: 족부편 네이버 책: MRI 자신감 키우기 2020년 봄, 개인 유튜브 채널을 통해 정리하며 공부하던 것을 동료, 후배 선생님들께 도 움이 되는 부끄럽지 않은 책으로 만들어보자는 생각에 계속된 수정과 내용 추가를 반복하 다보니..

In regard to shape, the morphology of the normal labrum demonstrates considerable variability on standard MR images. The cross-sectional shape of the labrum is triangular in most cases (anterior, 64%; posterior, 47%), followed by rounded (anterior, 17%; posterior, 33%). However, in a minority of cases the normal labral shape can be blunted, cleaved, notched, or even flat. The anterior and inferi..

The abduction external rotation (ABER) view is excellent for assessing the anteroinferior labrum at the 3-6 o'clock position, where most labral tears are located. In the ABER position, the inferior glenohumeral ligament is stretched resulting in tension on the anteroinferior labrum, allowing intra-articular contrast to get between the labral tear and the glenoid. The labrum is in the 3-6 o'clock..

Knowledge of the normal anatomy and physiology of the glenoid labrum is important for understanding the pathogenesis of labral tears. Let's see how flexible the labrum is. You might think that the labrum is rigid. Early authors thought the labrum was uniformly rigid in shape. The labrum is predominantly composed of moderately dense bundles of fibrous tissue and therefore is quite flexible. The c..

Meniscal ramp lesions can be defined as longitudinal vertical and/or oblique peripheral tears in the posterior horn of medial meniscus, in a mediolateral direction of less than 2.0 cm, that may lead to meniscocapsular or meniscotibial disruption with a concomitant ACL injury. There are few classifications regarding meniscal ramp lesions. Thaunat et al. approached a more comprehensive classificat..

The subtype 4A is a complete longitudinal vertical tear of the red-red zone of the meniscus, The subtype 4B involves a complete tear of the junction itself where the meniscocapsular and meniscotibial fibers attach to the posterior horn. A very peripheral meniscal tear(ramp type 4A lesion) can mimic ramp type 4B lesion. (Type 4B ramp lesion) There are edema and irregularity of the meniscocapsular..

https://youtu.be/HLYXPEdQ9Mc The perimeniscal fluid, edema of the posterior capsule, or even normal structures can be mistaken for a ramp lesion. Let's look at the normal meniscocapsular junction and find out the difference between these lesions and ramp lesions. The meniscocapsular junction of the posterior horn of medial meniscus is composed of the meniscocapsular ligament superiorly and the m..

Finally, look at the type 5 ramp lesion. In this tear pattern, there are two separate tears within the red- red zone of the meniscus. So this is called a double tear. Type 5 ramp lesions are similar to type 4a. The subtype 4A is a complete longitudinal vertical tear of the red-red zone of the meniscus, with the meniscocapsular and meniscotibial ligaments intact but connected to a portion of the ..
