Magnetic Resonance Visibility, Artifacts, and Overall Safety of the Self-Locating Peritoneal Dialysis Catheter with a Tungsten Tip

Figure 4

(a) Coronal fast-spin echo T1- and (b) T2-weighted images from an unenhanced abdominal MR study showing extensive paramagnetic “blooming” artifact at the lower end (arrow), corresponding to the site of the tip tungsten ballast. Axial T2- (c), coronal T1- (d), sagittal fat-suppressed (e), and T2- (f) weighted images performed to assess osteoporotic vertebral collapses show paramagnetic artifact (arrows) partially obscuring the anterior aspect of the sacrum.
