Article Synopsis
- This study aims to create a predictive model for osteoporosis and osteopenia by combining deep transfer learning (DTL) and classical radiomics features using dual-energy CT imaging.
- A total of 606 lumbar vertebrae were analyzed, with data split into training (424 vertebrae) and validation (182 vertebrae) groups, utilizing sophisticated feature extraction and classification methods.
- Results showed that the feature fusion model outperformed traditional methods, demonstrating high accuracy and clinical value for identifying both osteoporosis and osteopenia in patients.

Background: With the aging population of society, the incidence rate of osteoporosis is increasing year by year. Early diagnosis of osteoporosis plays a significant role in the progress of disease prevention. As newly developed technology, computed tomography (CT) radiomics could discover radiomic features difficult to recognize visually, providing convenient, comprehensive and accurate osteoporosis diagnosis.

Methods: A total of 119 participants were enrolled in our study (60 males, age: 50.88 ± 17.
Unlabelled: The vertebral compression fractures (VCFs) represent an incidental finding on thoracic and abdominal dual-energy CT examinations (which use STND reconstruction kernel), which are associated with increased mortality. While the BONE reconstruction kernel shows a superior diagnostic accuracy to find fractures. This study showed STND and BONE reconstruction kernel both had excellent diagnostic performance to detect abnormal edema in acute VCFs.

If it can be diagnosed at an early stage, osteoporosis is treatable. Quantitative computed tomography (QCT) is one of the current reference standards of BMD measurement, but dual-energy computed tomography (DECT) is considered to be a potential alternative.

The utility of using HAP-water decomposition technique with fast kilovoltage (KV)-switching dual-energy computed tomography (DECT) to detect abnormal edema in vertebral compression fractures (VCFs) has not been widely reported.
Methods: A total of 31 consecutive patients with 80 VCFs who underwent DECT and magnetic resonance imaging (MRI) of the spine were retrospectively enrolled in our study between October 2018 and January 2019.
