2025年3月17日 · Organizing pneumonia (OP) is a histological pattern of alveolar inflammation with varied etiology (including pulmonary infection). The idiopathic form of OP is called cryptogenic organizing pneumonia (COP) and it belongs to …

2022年9月12日 · High-resolution computed tomography (HRCT) of the lungs reveals bilateral patchy peripherally located consolidations or ground-glass opacities, which are often asymmetric. The classic HRCT sign described in COP is the atoll sign or the reverse halo sign.

2012年11月23日 · We conducted a review of serial high-resolution CT (HRCT) findings of cryptogenic organizing pneumonia (COP). MATERIALS AND METHODS. Over the course of 14 years, we saw 32 patients with biopsy-confirmed COP.

High-resolution computed tomography (HRCT) shows a variety of changes in the COP. Typically, the COP is sharply delineated from the surrounding parenchyma with a lobular pattern next to the bronchovascular structures.

2023年9月13日 · 隐源性机化性肺炎（COP）是特发性间质性肺炎（IIP）中的一种，占IIP的4%~12%，病理上以肺泡和肺泡管中肉芽组织栓形成为特征，肉芽组织栓可以延伸到细支气管。 本文通过回顾性分析22例，评估类固醇治疗前后COP患者影像学表现。 放射学特征. 机化性肺炎（OP）主要的HRCT表现包括：实变、磨玻璃影（GGO）、小叶周围不透明影、反晕征、结节或肿块、支气管壁增厚、支气管扩张、纵隔淋巴结肿大和胸腔积液。 COP 的放射学特征可分为 …

We conducted a review of serial high-resolution CT (HRCT) findings of cryptogenic organizing pneumonia (COP). MATERIALS AND METHODS. Over the course of 14 years, we saw 32 patients with biopsy-confirmed COP. Serial HRCT scans were available for only 22 patients (seven men and

2014年12月5日 · The three main characteristic imaging patterns of COP include multiple alveolar opacities (typical COP), solitary opacity (focal COP), and infiltrative opacities (infiltrative COP) that can be accurately discriminated by HRCT .

2017年11月1日 · Objectives: To help differentiate between COP and CEP using high-resolution CT (HRCT). Design: Clinical data and HRCT images of COP and CEP patients referred to Masih Daneshvari Hospital, Tehran, Iran, from 2007 to 2015 were reviewed. Diagnosis of COP or CEP was confirmed using open lung biopsy or a combination of transbronchial biopsy ...

Objective: We conducted a review of serial high-resolution CT (HRCT) findings of cryptogenic organizing pneumonia (COP). Materials and methods: Over the course of 14 years, we saw 32 patients with biopsy-confirmed COP. Serial HRCT scans were available for only 22 patients (seven men and 15 women; mean age, 52 years; median follow-up period, 8 ...

Background and objective: Cryptogenic organizing pneumonia (COP) is corticosteroid responsive but residual computed tomography (CT) chest changes are often noted. The present study examined clinical and HRCT features of COP in which there was incomplete resolution.
