Objective: To evaluate the value of Gallium-67 single-photon emission computed tomography/computed tomography in the diagnosis and monitoring treatment response of malignant otitis externa. Methods: Eight patients underwent 12 Gallium-67 single-photon emission computed tomography/computed tomography scintigraphy for eight suspected malignant otitis externa and were subsequently subjected to vis...

The origin of SPECT can be found in pioneering experiments on emission tomography performed approximately 50 years ago. This historical review consists of a compilation of first person recollections from nine trailblazing scientists who shaped the early years of SPECT instrumentation during the 1960s and 1970s.

BACKGROUND Hemodynamically significant coronary artery disease is an important indication for revascularization. Stress myocardial perfusion imaging is a noninvasive alternative to invasive fractional flow reserve for evaluating hemodynamically significant coronary artery disease. The aim was to determine the diagnostic accuracy of myocardial perfusion imaging by single-photon emission computed...

This paper intends to compare the abilities of the two major imaging modalities in nuclear medicine imaging: Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT). The motivations are many-fold: (i) To gain a better understanding of the strengths and limitations of the two imaging modalities in the context of recent and ongoing developments in hardware ...

Fever of unknown origin is still a medical challenge. Ga single photon emission computed tomography/computed tomography images are commonly used to evaluate the final diagnosis of fever of unknown origin. We presented a case of fever of unknown origin undergone Ga scintigraphy and an intra-abdominal Ga avid tumor was detected which suspected to be a neoplasm. Further contrast enhanced computed ...

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...

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...
