OBJECTIVES Although diffuse splenic (18)F-fluorodeoxyglucose (F-18 FDG) uptake exceeding hepatic activity, is considered abnormal, its clinical significance is rarely discussed in the literature. The aim of this study was to determine the contributing factors causing diffusely increased splenic FDG uptake in patients with cholangiocarcinoma. METHODS From January 2010 to March 2013, 140 patien...

OBJECTIVE It is sometimes difficult to assess I-131 lung uptake at the initial I-131 therapy because of strong artifacts from I-131 uptake in the thyroid bed. The aim of this study was to analyze the lung uptake at the second I-131 therapy for lung metastasis in patients who did not have lung uptake at the initial therapy from differentiated thyroid carcinoma (DTC). Then, we also analyzed the r...

amyloidosis is characterized by an abnormal extracellular deposition of amyloid in different organs, where it usually causes some type of dysfunction. its cause is unknown. five different types of amyloidosis have been described according to the underlying disease; immunoglobulin amyloidosis, familial amyloidosis, senile systemic amyloidosis, secondary amyloidosis and hemodialysis-associated am...

UNLABELLED The purpose of this study was to evaluate integrated (18)F-FDG PET/CT in patients with idiopathic pulmonary fibrosis (IPF) and diffuse parenchymal lung disease (DPLD). METHODS Thirty-six consecutive patients (31 men and 5 women; mean age +/- SD, 68.7 +/- 9.4 y) with IPF (n = 18) or other forms of DPLD (n = 18) were recruited for PET/CT and high-resolution CT (HRCT), acquired on the...

primary lymphomas of the lung are rare and usual radiographic findings are adenopathy, effusion, multiple lesions, solitary lesion or diffuse lesion. this paper presents a case of primary malignant tumor of the lung with a very rare radiological presentation. a 20-year-old male patient was admitted to our hospital due to fever, chills, productive cough and later development of hemoptysis. weigh...

Lung adenocarcinoma can exhibit a variety of radiological manifestations. However, the presence of diffuse cystic lesions in both lungs is extremely rare. Here, we report a case of a middle-aged woman with a primary lung adenocarcinoma that manifested as diffuse cystic lesions in bilateral lungs. Histopathological examination ultimately confirmed the lung adenocarcinoma. The patient was treated...

Acute lung injury (ALI) is characterized by the flooding of the alveolar airspaces with protein-rich edema fluid and diffuse alveolar damage. We have previously reported that transforming growth factor-beta1 (TGF-beta1) is a critical mediator of ALI after intratracheal administration of bleomycin or Escherichia coli endotoxin, at least in part due to effects on lung endothelial and alveolar epi...

Technetium-99m ((99m)Tc) sestamibi myocardial perfusion scintigraphy (MPI) is widely used for the diagnosis and assessment of prognosis in patients with suspected coronary artery disease. During these investigations, inspection of raw projected data for the purpose of quality control may occasionally yield incidental noncardiac findings that suggest the presence of another primary noncardiac di...

Background: Systemic sclerosis (SSc) is an autoimmune connective tissue disease characterized by vasculopathy and excessive collagen deposition in the skin and internal organs. Based on the skin damage we divide the patients into two groups: limited and diffuse SSc. In restricted type, the thickness of the skin is limited in the face and distal parts of the elbows and knees, with less involveme...
