Siderotic nodules radiology
WebIn a second phase, the method reproducibility in the detection and quantification of siderotic nodules (A: 1-5 nodules; B: 6-20 nodules; C: > 20 nodules) was evaluated in 30 patients who were submitted to ultrasonography blindly and independently assessed by two observers. Interobserver agreement was measured by kappa statistics. The reason why these nodules concentrate iron is uncertain, but it is attributed to differential iron metabolism in the nodule's cell population from differential transferrin expression 3. Stainable iron occurs in approximately 25% of all regenerative nodules 3. Of note, some prefer the term "iron-rich" … See more nodules are potentially hyperattenuating, but the amount of hyperattenuation may be slight, and the finding is non-specific See more
