1 Signal intensity is dependent on scaling
Signal intensity is dependent on scaling. A patient with a bone cyst following anterior cruciate ligament plasty. Signal intensity is dependent on scaling. A patient with a bone cyst following anterior cruciate ligament plasty. The axial images are obtained with T1-weighted (A), T1-frequency selective fat suppression (B), T1 Gd-chelate enhanced frequency selective fat suppression (C), and subtraction techniques (D). Note that the fluid has high signal intensity on the nonenhanced T1-weighted image with frequency selective fat suppression (B); which is in contrast to the ‘rule of thumb’ that fluid is of low intensity on T1. On the contrast enhanced (C) and subtraction images (D) only a small rim enhancement is seen. The explanation is the use of a grey scale on which the signal intensity of fat has been eliminated (see text). The axial T1- (A) and sagittal T2-weighted frequency selective fat suppressed (E) techniques show the well-known signal characteristics of fluid. Johan L Bloem et al.
