This study included consecutive 318 pairs of posteroanterior (PA) and left lateral (LL) chest radiographs taken under routinely used conditions with the patients in erect position. Major, minor and accessory fissures visualized on these ra-diographs were described according to their visibility, position , length and shape. On PA chest radiographs, superolateral major fissures in 54 (17%), super...

Segmentation of the pulmonary lobes is relevant in clinical practice and particularly challenging for cases with severe diseases or incomplete fissures. Automatic segmentation of the separate human lung lobes is a crucial task in computer aided diagnostics and intervention planning, and required for example for determination of disease spreading or pulmonary parenchyma quantification. In this w...

OBJECTIVE Patients undergoing pulmonary resections often present postoperative air leaks of varying magnitude and duration; this complication is more frequent with incomplete or absent interlobar fissures. Small leaks close spontaneously within 5-7 days; larger leaks may persist longer and could be associated with increased morbidity and prolonged hospitalization. We evaluated the role of diffe...

Pulmonary lobe segmentation is an important prerequisite for accurately quantifying pulmonary damage in many diseases and planning treatment. However, due to the incomplete lobar structures morphological changes caused by diseases, still encounters great challenges. In this study, a Learnable Interpolation Extrapolation Network (LIE-Net) proposed form complete consecutive fissure surfaces learn...

A pulmonary fissure is a boundary between the lobes in the lungs. Its segmentation is of clinical interest as it facilitates the assessment of lung disease on a lobar level. This paper describes a new approach for segmenting the major fissures in both lungs on thin-section computed tomography (CT). An image transformation called "ridge map" is proposed for enhancing the appearance of fissures o...

The Knowledge of variations in the lung can help surgeons to control bleeding during pulmonary lobectomy or might be used to reduce post-operative complications. Due to the importance of the knowledge of variations in lungs for clinicians, especially surgeons and radiologists, we report a case with lung lobe and fissure. During the autopsy of a 27-year-old man at the Legal Medicine Organizatio...

PURPOSE To investigate whether the integrity (completeness) of pulmonary fissures affects pulmonary function in patients with chronic obstructive pulmonary disease (COPD). MATERIALS AND METHODS A dataset consisting of 573 CT exams acquired on different subjects was collected from a COPD study. According to the global initiative for chronic obstructive lung disease (GOLD) criteria, these subje...

This study was aimed at determining major accessory fissures (MAF) and absence or incompleteness of lobar or major fissures (MF) during routine forensic autopsies. Prior to starting this prospective study, forms were prepared to collect data on pulmonary lobes and fissures. In this study, 420 lungs of 210 autopsy cases were examined for incompleteness and absence of MF and complete accessory fi...

We read with interest the article entitled “Volumetric thin-section CT: evaluation of pulmonary interlobar fissures” by Guan et al. (1) in the Nov-Dec 2015 issue of Diagnostic and Interventional Radiology. The authors gave detailed information about interlobar fissures, their incompleteness, relationship to vascular structures, CT appearance, and defect location. The interlobar fissures and the...

The aim of this study was to identify morphological and morphometric variations pulmonary fissures. A sample 50 adult formalin fixed Sri Lankan cadaveric lungs (24 left 26 right lungs) were observed with the help magnifying glass length measurements lung fissures taken using a measuring tape. Complete oblique fissure seen in 16 (66.67%) 11 (42.3%) lungs. Incomplete 8 (33.33%) 15 (57.69%) There ...
