背景情况:
- 评估骨密度对于牙植入成功至关重要.
- 圆束计算断层扫描 (CBCT) 提供灰色值 (GVs) 作为骨密度的间接测量.
- 植入物放置期间的平均扭矩读数为骨密度提供了直接的机械评估.
研究的目的:
- 评估平均扭矩读数与CBCT衍生的灰色值 (GVs) 之间的相关性,以评估骨密度.
- 为了比较不同类型的骨 (聚氨泡块和牛肋骨) 中的平均扭矩和GV的有效性.
- 确定平均扭矩是否可以作为骨密度评估中CBCT的补充工具.
主要方法:
- 从聚氨泡块和牛肋骨收集的平均扭矩数据.
- 在感兴趣的区域 (ROI) 中获得了测试材料的CBCT扫描和分析的灰色值 (GVs).
- 进行了相关性分析,以调查平均扭矩和重量级之间的关系.
主要成果:
- 在聚氨泡块中的平均扭矩和GV之间观察到强烈的相关性 (r = 0.94).

Bone Structure

Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.

Compact Bone
22.4K
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

Spongy Bone

All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT
973
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
