Radiology reports for incidental thyroid nodules on CT and MRI: high variability across subspecialties

Area of Science:

• Radiology
• Medical Imaging
• Endocrinology

Background:

• Variability in reporting incidental thyroid nodules on CT and MR imaging leads to inconsistent patient care.
• Standardized reporting is needed for incidental thyroid nodules.

Purpose of the Study:

• To describe radiologist reporting practices for incidental thyroid nodules on CT and MR imaging.
• To identify factors influencing these reporting styles.

Main Methods:

• Retrospective study of 375 patients with incidental thyroid nodules on CT/MR imaging (2011).
• Radiology reports analyzed for nodule reporting in "Findings" vs. "Impression" sections.
• Multivariate analysis to identify factors influencing reporting styles.

Main Results:

• 37% of incidental thyroid nodules were reported in the "Impression" section.
• Radiologist subspecialty and nodule size influenced reporting in "Impression".
• Higher variability in reporting was observed for nodules measuring 10-19 mm.

Conclusions:

• Nodule size and radiologist subspecialty are key factors in reporting incidental thyroid nodules.
• Variable reporting for 10-19 mm nodules highlights the need for standardized guidelines.
• Standardized reporting can improve consistency and quality of patient care.
