Lung involvement in systemic disease may be a manifestation of the underlying pathological process, may be a complication of the underlying disease or may be related to the treatment. Lung pathology is dominant in certain diseases, such as in Wegener’s granulomatosis, but may be only rarely present, for example in Henoch-Schönlein purpura. However, lung involvement has a profound eVect on progn...

Arachnoid granulations are rarely seen on high-resolution CT (HRCT) at the posterior temporal bone wall, where they appear as erosions, without bone spicules and often with a lobulated surface. Differential diagnosis includes endolymphatic sac tumor, paraganglioma, chordoma, and chondromatous and metastatic tumors. MR imaging can confirm the diagnosis because arachnoid granulations behave like ...

conclusions hrct is helpful in the diagnosis of invasive pulmonary aspergillosis in patients with lung-heart transplant. methods we reviewed the data of lung-heart transplant recipients within a 5 year period at our center. the inclusion criterion was confirmed invasive pulmonary aspergillosis. demographic, clinical, radiologic and laboratory characteristics of the patients were retrieved from ...

BACKGROUND A progressive lung disease and a worse survival have been observed in patients with systemic sclerosis and alveolitis. The objective of this study was to define the functional, radiological and biological markers of alveolitis in SSc patients. METHODS 100 SSc patients (76 with limited and 24 with diffuse disease) underwent a multistep assessment of cardiopulmonary system: pulmonary...

The identification of bronchi on High-resolution CT (HRCT) images of the lung provides valuable clinical information in patients with suspected airways diseases such as bronchiectasis. This paper presents a new method for automatic detection of bronchi for sparse HRCT data. Using sparse instead of volumetric data helps reduce the amount of data needed to be processed and stored. However, additi...

Kartagener's syndrome (KS) is characterised by bronchiectasis, paranasal sinusitis and situs inversus totalis (SIT). Association of diffuse bronchiolitis (DB) with KS has been documented from Japan only. Fourteen patients with SIT were seen in one unit over 7 years. All patients underwent a similar work up which included high resolution computed-tomography (HRCT) of thorax and CT-paranasal sinu...

Pulmonary Alveolar Proteinosis (PAP) is a rare syndrome in the paediatric age group and characterized by intra-alveolar accumulation of proteinaceous phospholipid-laden material called surfactant. The diagnosis is made by High Resolution Computed Tomography (HRCT) chest which shows characteristic crazy paving appearance and diagnosis confirmed by Bronchoalveolar Lavage (BAL). We report two case...

Cyst is described on high-resolution computed tomography (HRCT) as focal round area of parenchymal hyperlucency with a well-defined interface with normal lung. A relatively small subset of lung diseases should be suspected when cystic pattern is seen on HRCT. In particular, the differential diagnosis of this pattern relies upon features such as: cranio-caudal distribution, cystic shape, and coe...

This paper introduces a novel approach for automatic detection of a type of diffuse lung pattern, known as honeycombing, from high resolution computed tomography (HRCT) scans of the lung. The algorithm, which is based on frequency spectrum analysis of the HRCT image, assesses and combines outputs from a pre-defined Gabor filter bank to form a preliminary lesion detection mask. Several morpholog...
