Summary
A deep convolutional neural network (DCNN) computer-assisted diagnosis (CAD) system accurately detected osteoporosis on panoramic radiographs. This AI tool shows high agreement with expert radiologists, aiding early detection in dental settings.
Area of Science:
- Dentistry
- Radiology
- Artificial Intelligence in Medicine
Background:
- Osteoporosis diagnosis often relies on clinical assessment and bone density scans.
- Panoramic radiographs offer a readily available imaging modality for dental patients.
- Early detection of osteoporosis can prevent fractures and improve patient outcomes.
Purpose of the Study:
- To evaluate the diagnostic performance of a deep convolutional neural network (DCNN)-based computer-assisted diagnosis (CAD) system for osteoporosis detection.
- To compare the DCNN-CAD system's accuracy against diagnoses made by experienced oral and maxillofacial radiologists.
- To assess the potential of DCNN-CAD for early osteoporosis identification in dental practice.
Main Methods:
- 1268 female patients' panoramic radiographs were analyzed.
- Radiologists diagnosed osteoporosis based on mandibular inferior cortex erosion.
- Three DCNN models (SC-DCNN, SC-DCNN Augment, MC-DCNN) were applied to 200 radiographs for performance testing.
- Receiver operating characteristic (ROC) analysis was used to assess diagnostic performance.
Main Results:
- The area under the curve (AUC) values for the DCNN models were: SC-DCNN (0.9763), SC-DCNN Augment (0.9991), and MC-DCNN (0.9987).
- All tested DCNN models demonstrated high diagnostic accuracy in detecting osteoporosis.
- The DCNN-based CAD system showed strong agreement with expert radiologists' diagnoses.
Conclusions:
- The DCNN-based CAD system exhibits high diagnostic performance for osteoporosis detection on panoramic radiographs.
- This AI tool can assist dentists in the early identification of osteoporosis.
- Facilitating early referral of asymptomatic osteoporosis patients to medical professionals is a key benefit.

Convolution Properties II
590
The important convolution properties include width, area, differentiation, and integration properties.
The width property indicates that if the durations of input signals are T1 and T2, then the width of the output response equals the sum of both durations, irrespective of the shapes of the two functions. For instance, convolving two rectangular pulses with durations of 2 seconds and 1 second results in a function with a width of 3 seconds.
The area property asserts that the area under the...

Protein Networks
4.6K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
