Chest radiographs and pulmonary function tests are used as non-invasive techniques for the clinical management and guide to treatment in patients with diffuse interstitial pulmonary disease. The serial use of these tests may not give a true indication of the pathological activity of the disease process in the lung. Pulmonary function tests often remain abnormal despite inactivity of the patholo...

BACKGROUND Micronodular lesions are common findings in lung imaging. As an important differential diagnosis, we describe a case of diffuse idiopathic pulmonary neuroendocrine cell hyperplasia; it is notable that the diagnosis of diffuse idiopathic pulmonary neuroendocrine cell hyperplasia is often delayed. This case provides supporting evidence to establish lung biopsy by cryotechnique as the o...

The present case demonstrates a diffuse intense hepatic and, to a lesser degree, spleen, Tc-99m MDP uptake on a routine bone scintigraphy resembling liver-spleen imaging. A 49-year-old female with a history of anaplastic plasma cell tumor and suffering from bone pain was referred for bone scintigraphy to evaluate possible bone metastases. The bone scintigraphy showed diffuse hepatic and spleen ...

where Pabs is the absolute pressure and FtN2 is the fractional concentration of N2. If a diver, breathing 20% oxygen and 80% nitrogen, swims down to 30 MSW the inspired PN2 (PiN2) is calculated from equation 1 as: PiN2 = 4 bars x 0.8 = 3.2 bars. The lung alveolar PN2 (PAN2) will be slightly lower than this, but for the sake of simplicity we will assume that it also is 3.2 bars. The venous blood...

We present an interesting case of incidental diffuse fluorodeoxyglucose (FDG) uptake at PET in her left breast, related to atypical breastfeeding practice. Clinically, differential diagnoses of diffuse intense FDG uptake in unilateral breast include advanced breast cancer, breast lymphoma and inflammatory condition. However, normal physiologic lactation may also show increased FDG uptake in the...

We introduce a novel computational framework to enable automated identification of texture and shape features of lesions on (18)F-FDG-PET images through a graph-based image segmentation method. The proposed framework predicts future morphological changes of lesions with high accuracy. The presented methodology has several benefits over conventional qualitative and semi-quantitative methods, due...

many different radiologic appearances. The common radiologic appearances are those of a solitary peripheral pulmonary nodule, multiple nodules and lobar or diffuse consolidation (1). The unusual radiologic appearances include diffuse disease with minimal or no radiologic signs, expansive pulmonary consolidation without air bronchograms, lobar atelectasis and cavitation (1). To the best of our k...

A diffuse interstitial infiltrative pattern of lung metastasis in a patient with malignant melanoma is rare and can be confused with benign conditions such as pulmonary edema or drug-induced pneumonitis. We experienced a case of diffuse interstitial infiltrative lung metastasis in malignant melanoma in a 37-year-old man. This case was confirmed by a transbronchial lung biopsy. We herein describ...
