A case of giant cell tumor of the thoracic spine simulating mediastinal neoplasm was identified on plain films, CT scans, MR images, and with scintigraphy. CT showed a hypervascular soft-tissue mass with shell-like calcification in the right upper mediastinum. MR imaging showed a collapse of the T1 vertebral body and a mass extending to the mediastinum. The mass had a low signal on T1-weighted ...

Gallium-67 citrate (67Ga) scintigraphy has been used as an indicator of activity of diffuse interstitial lung diseases. However, little has been mentioned in pulmonary alveolar proteinosis (PAP). Here we present a 53-year-old man with PAP showing patchy 67Ga uptake by single photon emission computed tomography (SPECT). Interestingly, the strong 67Ga uptake was observed in areas where ground-gla...

Introduction: Nuclear Scintigraphy is a highly sensitive, alternative imaging modality used in human and veterinary medicine. This modality involves the administration of a radioactive substance (radioisotope) to a patient. Generally, the radioisotope is labeled to a specific compound. This labeled combination is known as a radiopharmaceutical. These radiopharmaceuticals are formulated in vario...

Castleman’s disease is a rare lympho proliferative disorder with unclear pathogenesis. It is found in two forms, localized (uni-centric) and multi-centric. Histologically there are two forms; hyaline vascular and plasma cell type. The disease is definitely diagnosed by histological examination after biopsy. Computed Tomography (CT), Magnetic Resonance Imaging (MRI), Gallium 67 scintigraphy can ...

Advances in radiology have helped in early diagnosis, surveillance and proper management of disease processes. SPECT scintigraphy is an imaging modality that helps in the detection & diagnosis of facial & skull osteomyelitis and is also useful for detecting silent lesions. Pentoxifylline-tocopherol together helps in faster healing of diseased bone. Pentoxifylline reduces blood viscosity and thu...

Diffuse pulmonary uptake in 67-gallium citrate (67-Ga) scintigraphy occurs in a large number of neoplastic and inflammatory conditions. Discrimination between normal and abnormal 67-Ga uptake over the chest can be difficult and a simple visual method for identifying abnormal studies is described. A series of 39 gallium scintigrams was retrospectively reviewed by the authors and reported without...

Diagnostic value of 67Ga-scintigraphy in chest surgery. Gallium-67 (67Ga) has a high affinity for malignant tissue. The diagnostic value of 67Ga-scintigraphy for differentiating between malignant and benign disease was studied in 109 patients with lesions of the chest discovered by radiological examination. Histological diagnoses were obtained in all the patients after the study was concluded. ...
