Introduction: In spite of all the researches on medical imaging, this field is still hot. It is the third major area of research, conducted in the world. Unfortunately, there is no statistical evaluation available of the student theses in Iran. It does not seem like a policy is going to be established to address this issue. Providing a statistical insight to activities done in ...

Introduction: Squamous Cell Carcinoma (SCC) is the most common head and neck malignancy. To decrease the side effects of treatment and mortality from disease relapse, careful staging for the proper treatment plan is necessary. The main purpose of this prospective study is to compare the diagnostic value of Computed Tomography (CT) and Magnetic Resonance Im-aging (MRI) in oral SCC and its lymph ...

FDG PET CT scan is considered to be a sensitive tool to detect skeletal metastasis in known malignancies. However, it’s high sensitivity and low specificity may account for false positive diagnosis in cases of trauma, infection, inflammation and other benign conditions. Skeletal hemangioma is one of the common benign conditions which are typically ametabolic on FDG PET CT with no uptake on bone...

This paper provides a review of analytical tools and clinical application in the field 4D flow MRI. The convention Magnetic Resonance Imaging (MRI) practice for valuation affected role with cardiovascular disease is now commonplace. Two-dimensional stage contrast MRI has remained cast-off to amount local plasma movement heart arteries since late 1980s. Recently time determined magnetic timbre i...

Introduction: Computed tomography (CT) has numerous applications in clinical procedures but its main problem is its high radiation dose to the patients compared to other imaging modalities using x-ray. CT delivers approximately high doses to the nearby tissues due to the scattering effect, fan beam (beam divergence) and limited collimator efficiency. The radiation dose from multi-slice scanners...

the most common soft tissue tumors during infancy and childhood are vascular lesions. although the vast majority of these lesions have typical clinical features and do not require any further exam, but sometimes atypical superficial or deeply located lesions need complementary studies to be diagnosed and classified. in that way it is also very important to exclude very less common malignant sof...

Gliomas account for almost 80% of primary malignant brain tumors in adults. Magnetic Resonance imaging (MRI) is still the gold standard for diagnosis of brain tumors and brain 99mTc-tetrofosmin Single Photon Emission Computed Tomography (99mTc-tetrofosmin-SPECT) has been established as a useful tool for their evaluation. Fluorine-18–2-fluoro-2-deoxy-d-glucose positron emi...
