Physical aspects of MRI tissue suppression after breast augmentation surgery
- Georgiev, V. Ivanov, G. Kirova, P. Ilieva
Magnetic resonance imaging of the breast implants has been shown to be highly accurate in detecting complications and superimposed disease into the surrounding breast parenchyma. However, there are some clinical problems with these patients – a lack of accurate information on the materials used for breast implants because of the long interval between implantation and MRI and cross-signal intensity of the pathological tissue, based on the conventional T1 and T2 sequences. The aim of the article is to explain the physical aspects of some specific MR sequences, focused on the selective tissue characterization. The main principles of the different water-, silicone- and fat suppression techniques are presented with some image and case selective illustrations.
