this article is intended to provide an overview of various aspects of clinical pet/ct. these include discussions of: (i) important areas of clinical application; (ii) opportunities in clinical research; (iii) scanner and operating-mode considerations (e.g. bgo vs. lso, lyso or gso scanners, 2d vs. 3d imaging). (iv) study-specific considerations (e.g. patient preparation and positioning issues, ...

widespread studies on tumor diagnosis has led to the development of techniques with greater sensitivity and improved specificity for detection of occult and small subclinical tumors. tumor imaging by radiolabeling of tumor-specific antibodies (immunoscintigraphy) or tissue specific biochemical agents (receptor imaging) and especially physiologic imaging with positron emitters (pet), have opened...

dependency of clinicians and surgeons on imaging studies for primary evaluation of patients and also for follow up of them, significantly increased in recent years, parallel to advances in imaging methods and new imaging modalities. regarding to these tips, it is important that we can use new concepts in conducting imaging to fulfill new requirements of clinicians and then provide sufficient da...

in ultra-wideband (uwb) multistatic microwave breast cancer imaging, the long imaging time is an important issue. in this paper, a novel imaging method for multistatic uwb radarbased microwave breast cancer imaging using sparse sampling has been proposed that significantly reduces the amount of data and imaging time. in this method, instead of measuring multistatic radar signals conventionally,...

patients and methods in this cross-sectional study, we evaluated all patients referred to a single rheumatology clinic for bone mineral density measurements from 2009 to 2010. all patients who had bone mineral density measurements taken from the hip, lumbar spine, forearm, and whole body were enrolled in the study. standard bone mineral density measurements were performed using a dual energy x-...

intracranial gliosis has no typical clinical signals or imaging characteristics. therefore, it can be easily misdiagnosed as neoplasm. hereby, we report a unique case of gliosis that grew outward from the surface of the brain. mri depicted its signal and enhancement pattern similar to the cerebral gray matter. the diagnosis was confirmed by pathology and immunohistochemistry. although it was di...

abstract a patient with a 3-month history of headache refractory to pain medication was admitted. the ct scan and mri showed evidence of a posterior fossa mass. this was pathologically confirmed as an extra medullary plasmacytoma (emp). he had a pathologic fracture of the left humerus 7 years ago while the radiologist was unaware at the time of diagnosis. a solitary bone plasmacytoma (sbp) was ...

intracranial lipoma is an uncommon entity. a rare type of tumor in the internal auditory canal (iac) and the cerebellopontine angle (cpa) is lipoma. there are a few case reports in the literature related to intravestibular lipoma. herein, we report a case of lipomas within the cerebellopontine angle and vestibule of the inner ear in a patient with tinnitus and dizziness. the patient was evaluat...
