AIM The aim of this study was to evaluate the value of bone scintigraphy for the assessment of graft viability following vascularized bone grafts in patients with mandibular reconstruction. METHODS We investigated 16 patients with vascularized grafts from the fibula (13 patients) and iliac crest (3 patients) in the last 8 years. For the follow up of all these patients, Tc-99m MDP bone scintig...

To the Editor: Pleural malignant mesothelioma (MM) is an uncommon neoplasm with poor prognosis, strongly related to asbestos exposure, arising from mesothelial cells of the pleura. Pleurodynia is its most usual symptom, whereas the presence of pleural effusion combined with thickened pleura and calcified plaques in both computed tomographic (CT) images and respective histopathological findings ...

A 6-year-old, female Alaskan malamute domestic dog was presented for a bone scintigraphy with a soft tissue tumour of 4 months duration. The tumour at the time of scintigraphic examination was 10 cm in diameter and was localized in the lateral line on the right chest along the 11th rib. Pathologic diagnosis based upon fine needle biopsy was osteogenic sarcoma. The aim of the scan was to assess ...

The uptake of (99m)Tc-methylene diphosphonate (MDP) in malignant pleural effusions and, rarely, in nonmalignant pleural effusions has been well documented in the literature. Although the exact mechanism of uptake in these conditions remains unclear, there have been attempts to use the bone scintigraphic features of pleural effusion to predict sensitivity and specificity for malignancy based on ...

onstrated that the orifice and lumen of the right middle lobe bronchus were significantly obstructed by an irregular mass ( fig. 2 ). There were no mediastinal or pleural abnormalities. Bronchoscopy revealed a large gray mass subtotally obstructing the right middle lobe bronchus ( fig. 3 ). This was biopsied without incident. Histopathological examination showed sheets of spindle-shaped, pleomo...

PURPOSE The role of fusion imaging methods SPECT-CT and PET-CT is currently being investigated in radiotherapy (RT) treatment planning. SPECT and PET provide extra information for gross tumor volume (GTV) delineation. The purpose of this study was to evaluate the role of SPECT-CT in RT. METHODS SPECT-CT studies were performed in 55 patients with (99m)Tc-MIBI/Tetrofosmin (TF), with 99mTc-Nanoc...
