概括
状鼻的停止性气动化 (AP) 经常被误诊. 典型的CT和FDG-PET发现有助于区分AP与骨底部病变.
科学领域:
- 放射学 放射学是一门学科.
- 耳鼻喉科 耳鼻喉科 耳鼻喉科
- 头骨底部成像成像 头骨底部成像
背景情况:
- 停止性肺炎 (AP) 是状鼻的一个未被认可的解剖变体.
- AP可以被误认为是瘤或其他病理性病变,导致不必要的后续成像.
研究的目的:
- 通过CT,MRI和FDG-PET研究AP的成像特征.
- 根据成像发现,区分AP与其他头骨底部病变.
主要方法:
- 对442名接受FDG-PET/CT的患者多检测器低剂量CT扫描的回顾性审查.
- 对22名AP患者CT,MRI和FDG-PET/CT发现的分析.
- 对AP成像检测结果与纤维发育不良症,冠状腺瘤,冠状腺瘤,多发性骨髓瘤和鼻癌骨侵袭的比较.
主要成果:
- 在CT上,AP呈现为非扩张性病变,CT上具有精确的硬化边缘.
- 在T1/T2加权的MRI上,AP显示了高信号强度.
- FDG-PET显示在AP中吸收率不显著 (SUVmax:0.85),与其他头骨底部病变中适度至严重的吸收率 (SUVmax:1.8-8.4) 相比.
结论:
- 非扩张性CT发现和PET上缺乏FDG吸收是AP的特征.
- 这些成像特征可以帮助区分AP与其他头骨底部病理,从而避免不必要的调查.

Cranial Bones: Lateral View
2.3K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Sutures of the Skull
6.8K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Pneumothorax-II
170
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

Mitral Stenosis II: Clinical features and Diagnostic Tests
22
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...
