2023年5月2日 · Acute interstitial pneumonia (AIP), also known as Hamman-Rich syndrome, is a rapidly progressive non-infectious interstitial lung disease of unknown etiology. It is considered the only acute process among the idiopathic interstitial pneumonias.

Objective: The purpose of this study was to evaluate the relation between pathologic phases and high-resolution CT (HRCT) findings in patients with acute interstitial pneumonia (AIP). Materials and methods: Our retrospective review found 14 patients with …

2013年1月19日 · Acute interstitial pneumonia: high-resolution CT findings correlated with pathology. The purpose of this study was to evaluate the relation between pathologic phases and high-resolution CT (HRCT) findings in patients with acute interstitial pneumonia (AIP). Our retrospective review found 14 patients with AIP who were included in this study.

扫描后生成平均密度 (AIP)和最大密度投影 (MIP)CT, 并进行4D-CT重建。 用Nomos Corvus V8.0放疗计划系统和IBA OmniPro I'mRT软件, 分析靶区在AIP、MIP CT及两个极限呼吸相位4D-CT中的大小及其相互关系; 自制周期运动体模分析窗宽/窗位对平均密度和最大密度投影CT中靶区形态的影响。 结果 AIP CT中靶区大于两个极限相位4D-CT中的靶区, 其比值分别为1.30和1.07;MIP CT中的靶区大于两个极限相位4D-CT中的靶区, 其比值分别为1.57和1.21。 结论 用AIP CT和MIP CT能 …

2005年7月1日 · The diagnosis of idiopathic interstitial pneumonia is made by means of correlation of clinical, imaging, and pathologic features. The characteristic computed tomographic (CT) features of UIP are predominantly basal and peripheral reticular pattern with honeycombing and traction bronchiectasis.

This study compared high-resolution computed tomography (CT) findings between 10 survivors and 21 nonsurvivors of acute interstitial pneumonia and evaluated whether the CT findings were predictive of patients' response to treatment.

2012年11月23日 · AIP is the only idiopathic interstitial pneumonia with an acute onset of symptoms. Patients often report a prodromal illness suggestive of a viral upper respiratory tract infection with symptoms such as fever, chills, myalgias, cough, and dyspnea followed by rapidly progressive severe exertional dyspnea that develops over a few days [1, 2].

2019年7月21日 · Acute interstitial pneumonia: radiographic and CT findings. (A) Chest radiograph shows extensive bilateral areas of consolidation involving mainly the lower lung zones. (B) High-resolution CT scan shows extensive bilateral areas of consolidation with air bronchograms in a peripheral and dependent distribution.

The authors conclude that the radiographic and CT features of AIP are similar to those of adult respiratory distress syndrome and represent acute alveolar damage. AIP differs from the more chronic forms of interstitial pneumonia in clinical presentation and in …

2024年1月1日 · 研究发现，CT平均密度投影（AIP）重建技术可以生成“合成”CX图像，这有望提高CX和CT图像比较的准确性，特别是在检测常见胸膜-实质异常时。 这项研究旨在评估使用合成CX图像在检测常见胸膜-实质异常方面的诊断性能。 研究纳入了进行胸部CT检查和CXR检查的142名患者。 CT被视为参考标准。 三名阅片医生分别在两个独立的阅片会议中回顾了传统CX图像和合成CX图像，检测肺实质浓缩、结节/肿块、线状浓度、网状浓度和胸腔积液的存在。 针对 …
