This work presents a method for the segmentation and reconstruction of the pulmonary parenchyma in CT images. The identification and outline of the pulmonary parenchyma is essential to analyze the pulmonary volume and is an important stage in automatic or semi-automatic processes for detecting lesions, vessels and the bronchial tree. The method proposed here combines traditional concepts, such ...

The destruction of renal parenchyma caused by excess deflection of the sheath was examined to determine at what level of force the renal parenchyma was ruptured during PNL. The kidney obtained from right nephroureterectomy due to renal pelvic cancer (stage T2N0M0) of a 54-year-old female patient was punctured at the posterolateral portion with a puncture needle. The tract was dilated up to 26 F...

Lung parenchyma resection is the treatment of choice for early-stage lung cancer. The surgery involves the loss of respiratory surface and consequently leads to reduction in exercise capacity. Proper rehabilitation is essential for restoring the function and good performance of the respiratory system. Rehabilitation should be an integral part of surgical treatment. It should be implemented earl...

Iopamidol, a nonionic, water-soluble contrast medium, has been recently recommended for myelography. As with other such media, the extent of parenchymal penetration is of interest in relation to the genesis of clinical complications. In this study the degree and depth of brain penetration of intrathecal iopamidol, using an iodine concentration of 280 mg l/ml, were compared at 15 and 60 min in a...

Interdependence between airways and the lung parenchyma is thought to be a major mechanism preventing excessive airway narrowing during bronchoconstriction. Because the elastance of the lung increases during bronchoconstriction, the lung's tethering force could also increase, further attenuating bronchoconstriction. We hypothesized that the bulk (kappa) and shear moduli (mu) of the lung increas...
