Magnetic resonance imaging for assessing treatment response in bone marrow metastases

Abstract

Cancer metastasis to bone is a frequent observation in malignancy that may result in complications such as pathological fractures and spinal cord compression. Monitoring treatment effects is the main concern in oncology; however, the evaluation of treatment response in bone is particularly challenging as it lacks well-established criteria. In addition, bone metastases have traditionally been considered non-measurable manifestations of cancer. Magnetic resonance imaging (MRI) is one of the most specific and sensitive methods for imaging skeletal metastases. The aim of this article is to highlight the diagnostic performance of MRI in the treatment monitoring of bone metastases, to review the current literature, and to provide an overview of recommendations for the evaluation of treatment response in bone.

Diffusion-Weighted Magnetic Resonance Imaging of Spine

“…항암화학요법이나 방사선치료 후 치료 효과 판정을 위한 영상검사방법 중 T1WI를 중심으로 한 고식적 MRI가 중요한 역할을 한다( 41 ). 이는 골수 내 병변의 크기와 부피를 정확하게 측정할 수 있는 재현성 높은 방법이다.…”

Multiparametric Magnetic Resonance Imaging of Penile Cancer: A Pictorial Review

“…Finally, contrast-enhanced imaging, both for dynamic and static applications, can be performed using the Dixon technique, which allows for homogeneous, fat-free imaging, even in the presence of magnetic susceptibility [48]. High-resolution DCE-MRI has previously been shown to detect superficial, tumor-like skin lesions as small as 1-2 mm, and can be beneficial in the work-up of penile cancers [49].…”
