ABSTRACTNeuroimaging allows noninvasive evaluation of the anatomy, physiology, and function of the brain. It is widely used for diagnosis, treatment planning, and treatment evaluation of neurological disorders as well as understanding functions of the brain in health and disease. Neuroimaging modalities include X-ray computed tomography (CT), magnetic resonance imaging (MRI), single photon emis...

Selective and sensitive tumor imaging in vivo is one of the most requested methodologies in medical sciences. Although several imaging modalities have been developed including positron emission tomography (PET) and magnetic resonance (MR) imaging for the detection of tumors, none of these modalities can activate the signals upon being accumulated or uptaken to tumor sites. Among these modalitie...

background: general practitioners (gps) are usually the first-line doctors visiting patients with breast problems. therefore, their knowledge about breast diseases is of significant importance for proper screening and referral of patients and warrants scrutiny. the purpose of this study was to assess the knowledge of gps regarding different breast imaging modalities. methods: in this cross-sect...

INTRODUCTION U.S. Army Special Forces Medics (18Ds) operate in austere environments where decisions regarding patient management may be limited by available resources. Portable ultrasound may allow for the detection of fractures in environments where other imaging modalities such as radiography are not readily available or practical. OBJECTIVE We used a simulation training model for the ultra...

Brown tumors (BT) are scarcely diagnosed and present a possible diagnostic pitfall in imaging modalities. Imaging modalities and especially positron emission tomography cannot differentiate between brown tumors and metastatic foci and only clinical diagnosis of hyperparathyroidism and histology will support the diagnosis. We describe the histology, clinical expression, significance and the diff...

introduction: radiography is one of the most important diagnostic methods for evaluation of dental caries. on the other hand, the least amount of radiation along with high quality is a main gold standard. the purpose of this study was to compare the diagnostic accuracy of primax, insight radiographic films, and direct digital images (schick cmos-aps), in detection of interproximal natural carie...

in this regards first of all cross sectional anatomy of salivary glands and different diagnostic modalities such as ultrasound, cat scan, conventional mri and nuclear studies will be discussed. advanced mri modality such as dce (dynamic susceptibility enhanced) imaging will be introduced. then various pathologies of salivary glands including infectious, benign and malignant neoplastic processes...
