PURPOSE To investigate the added value of post-contrast VIBE (volumetric-interpolated breath-hold examination) to PET/MR imaging for pulmonary nodule detection in patients with primary malignancies. MATERIALS AND METHODS This retrospective institutional review board-approved study, with waiver of informed consent, included 51 consecutive patients who underwent 18F-fluorodeoxyglucose (FDG) PET...

PURPOSE To assess the feasibility of computed tomography (CT)-guided localization using a specific long dual-barbed hookwire in resection of pulmonary nodules with the size of 20mm or less by video-assisted thoracoscopic surgery (VATS) and to discuss the necessity of early treatment of small pulmonary nodules by VATS. RESULTS All the nodules were successfully localized with hook wire under CT...

Pulmonary necrobiotic nodules represent a rare extra-intestinal manifestation of Crohn's disease. Histologically, they are composed of sterile aggregates of inflammatory cells with necrosis. The differential diagnosis is broad, and exclusion of infectious etiologies is mandatory before starting immunosuppressive therapy. Here, we present the fifth reported case of pulmonary necrobiotic nodules ...

BACKGROUND The objectives of this study were to evaluate the influence of iterative reconstruction (IR) on pulmonary nodule volumetry with chest computed tomography (CT). METHODS Twenty patients (12 women and 8 men, mean age 61.9, range 32-87) underwent evaluation of pulmonary nodules with a 64-slice CT-scanner. Data were reconstructed using filtered back projection (FBP) and IR (Philips Heal...

Incidental pulmonary nodules in patients that are imaged for staging purposes or during follow-up may represent metastases, second primary tumours (lung cancer) or benign nodules. The probability of pulmonary metastases or primary lung cancer differs depending on the number, size, size distribution and morphology of the nodules as well as the histologic type, stage, grade and other features of ...

OBJECTIVE Video-assisted thoracic surgery (VATS) is a new procedure that makes it possible to see the intrathoracic organs and to resect pulmonary nodules without thoracotomy. Preoperative localization of small nodules that may not be visible or palpable during VATS is desirable. Percutaneous placement of spring hookwires is widely used to localize pulmonary nodules before VATS; infrequently, t...

We report a 45-year-old man with epithelioid hemangioendothelioma (EH) and simultaneous pulmonary metastasis of thyroid cancer in his lung. Thyroid cancer, and multiple small nodules in both lungs were noted. He underwent total thyroidectomy followed by radiotherapy with 131I. However, 131I scintigraphy showed poor uptake of radionuclide in the nodules, and the size of the nodules remained unch...

We report here a case of primary pulmonary epithelioid hemangioendothelioma diagnosed in a 67-year-old Caucasian man, presenting with exertion dyspnoea, dry cough, and multiple bilateral pulmonary nodules revealed by computed tomography. At the 18F-fluorodeoxyglucose positron emission tomography, these nodules were negative. The histopathological diagnosis was made on a pulmonary wedge resectio...

Lungs segmentation is a vital step for computer aided diagnosis. Many lungs diseases requiring radiological support for diagnostic purpose, including tuberculosis, emphysema and lungs cancer could be affectively diagnosed using computer-aid. Pulmonary nodules usually act as the early stage characterization of lung cancer. It’s a crucial way to control the disease and reduce the mortality by fur...
