Development and validation of a CT-based comprehensive nomogram for differentiating benign from malignant subcentimeter solid nodules

This study confirms that MPVR-maximum diameter is an independent factor for predicting the malignancy of SSPN. By comparing various radiological models constructed based on high-resolution CT (HRCT) images, it is found that the nomogram integrating the IntraPeri3mm model and MPVR-maximum diameter has the optimal predictive efficiency. The above results provide an important scientific basis for the early diagnosis and treatment of SSPN.
