Single Photon Emission Computed Tomography/Computed Tomography (SPECT/CT) of the Skull in Necrotizing Otitis Externa: Comparison with Planar Bone Scintigraphy, SPECT and CT
ثبت نشده
چکیده
Necrotizing otitis externa (NOE), also called malignant otitis externa, corresponds to osteomyelitis of the skull base [1]. NOE occurs primarily in diabetic elderly patients with a male preponderance [2]. Typically due to pseudomonas aeruginosa, NOE begins as a soft tissue infection of the external auditory canal (EAC) and spreads via the fissures of Santorini and the tympanomastoid suture to involve the cranial base [3].

SPECT-CT fusion in the diagnosis of hyperparathyroidism
Objective(s): In this study, we aimed to analyze the relationship between the diagnostic ability of fused single photon emission computed tomography/computed tomography (SPECT/CT) images in localization of parathyroid lesions and the size of adenomas or hyperplastic glands. Methods: Five patients with primary hyperparathyroidism (PHPT) and 4 patients with secondary hyperparathyroidism (SHPT) we...
متن کاملSPECT/CT imaging in bone scintigraphy of a case of clavicular osteoma
Osteoma is a benign bone-forming tumor that usually arises in the craniofacial bones and rarely in the long bones. Clavicular involvement is extremely rare. We report a 51-year-old woman with osteoma of the left clavicle. Radiograph of the left shoulder showed a well-defined lobulated blastic mass in the proximal and mid-portion of the left clavicle. Bone scintigraphy was performed 4 hours afte...

Objective(s): Nuclear medicine technologists in Japan often perform additional single-photon emission computed tomography (SPECT) with or without computed tomography (CT) after whole-body imaging for bone scintigraphy. In this study, we wanted to identify the bone scanning protocols used in Japan, together with the current clinical practices. Methods:...

We report a three-phase bone scintigraphy for the diagnosis of a peripheral bone lesion caused by systemic sarcoidosis. A 32-year-old man with suspected osteomyelitis of the right forefinger underwent three-phase bone scintigraphy with Tc-99m hydroxymethylene diphosphonate (HMDP) and single-photon emission computed tomography/computed tomography (SPECT/CT). The lesion was rich in blood flow acc...
متن کاملDiagnostic uncertainty of isolated skull lesion in prostate cancer- Role of SPECT/CT
Skeletal involvement is the second most common site of metastases after lymph nodal metastases in patients with prostate cancer. The skeletal metastases from prostate cancer are osteoblastic in nature and show increased tracer avidity on the bone scan. Focal tracer avid lesion in skeleton especially in skull requires the careful examination by further investigation. The patients with skull meta...
