Volumetric Analysis: Effect on Diagnosis and Management of Indeterminate Solid Pulmonary Nodules in Routine Clinical...

Area of Science:

• Pulmonology
• Radiology
• Oncology

Background:

• Indeterminate solid pulmonary nodules require careful evaluation for malignancy.
• Accurate diagnosis and timely management are crucial for patient outcomes.

Purpose of the Study:

• To assess the impact of volumetric analysis on the diagnosis and management of indeterminate solid pulmonary nodules in clinical practice.

Main Methods:

• Retrospective review of 107 computed tomography (CT) cases with solid pulmonary nodules (6-15 mm).
• Inclusion of 57 malignancies and 50 benign nodules across 309 CT scans.
• Nine radiologists evaluated nodules with and without volumetric data, assessing malignancy suspicion and management recommendations.

Main Results:

• Volumetric analysis significantly improved sensitivity for detecting malignant nodules (P = 0.009).
• It facilitated earlier recognition of malignancies (P < 0.05) and improved interobserver agreement (P = 0.004).
• Management recommendations were influenced by volumetric data, particularly in experienced radiologists.

Conclusions:

• Volumetric analysis enhances the sensitivity and timeliness of malignant pulmonary nodule identification.
• Its effect on management is variable and depends on the reader's experience level.
