PURPOSE We aimed to perform an imaging analysis of interlobar fissures and their variations using thin-section computed tomography (CT). METHODS Volumetric thin-section CT scanning was performed in 208 subjects. Interlobar fissures were observed on axial images, and reconstructed coronal and sagittal images were observed by multiplanar reformatting (MPR). The vessel distributions were verifie...

Anatomical variations of lungs are common in clinical practice; however, they are sometimes overlooked in routine imaging. Surgical anatomy of the lung is complex and many variations are known to occur. A defective pulmonary development gives rise to variations in lobes and fissures. Morphological presentation is of clinical importance and profound knowledge of the organogenesis and functional ...

The lungs are divided by the fissures into different lobes. The oblique fissure divides the left lung in to two lobes namely the upper and lower lobes. Defective pulmonary development gives rise to variations in lobes and fissures of lung. In the present case, we report an unreported variant lobar pattern of the left lung, in which the left lung was completely separated in to anterior and poste...

The term phantom tumor may be used to describe a well-demarcated opacity resulted from pleural effusion. Phantom tumors are commonly associated with congestive heart failure causing transudative pleural effusion within pulmonary fissures. The figure may bring about inaccurate invasive diagnostic interventions. We report a heavy smoker patient with multiple phantom tumors in the right lung resol...

In evaluating thoracic function, it is effective to segment the five lung lobes from multidetector-row computed tomography (MDCT) images. Almost all of the conventional methods are based on extracting the lobar fissures; however, some parts of the fissures may not be observed from MDCT images due to CT artifacts and/or adhesions between the lung lobes. This article proposes an alternative metho...

Segmentation is an important process in the field of medical imaging, as it can provide detailed information of an image. In this work, segmentation of pulmonary lobe is carried out which is useful for the clinical interpretation of CT images, to access the early presence and the characterization of several lung diseases. This segmentation process is challenging for severely diseased lung or lu...

Pulmonary fissures separate human lungs into five distinct regions called lobes. Detection of fissure is essential for localization of the lobar distribution of lung diseases, surgical planning and follow-up. Treatment planning also requires calculation of the lobe volume. This volume estimation mandates accurate segmentation of the fissures. Presence of other structures (like vessels) near the...
