background: breast is one of the main radiological sensitive organs, hence it is important to evaluate absorbed dose to this organ especially to the glandular parts. it is the aim of this study to measure mean glandular dose and image contrast in terms of different mammographic parameters. materials and methods: in this study two mammography machines located at said-al shohada (giotto) and shah...

up to 19% of breast malignancies may be missed by conventional imaging techniques, especially when they are concurrent or co-located with other benign lesions. however, more sensitive techniques, such as magnetic resonance imaging (mri), are often too expensive for routine use in developing countries. contrast-enhanced, dual-energy digital mammography (cesm) is a recently introduced imaging mod...

  Purpose: To recognize affective factors in delivering X-ray contrast agents (which have high atomic number) via gallium carrier to liver or lymphatic neoplasm cells.   Materials and Methods: Since uptake of gallium by liver has been reported in numerous researches, it was bonded with a contrast media (metrizoate). X-ray imaging was done to determine geometric features of liver.   Results: Rad...

Objective- To evaluate and compare the radiographic efficacy and safety of a non-ionic dimeric and isotonic iodinated contrast medium, iodixanol (320 mgI/ml) and a non-ionic monomer and hypertonic contrast medium, iohexol (300 mgI/ml) in feline cervical myelography. Design- Experimental study Animals- Five adult healthy cats. Procedures- Iodixanol and iohexol were injected into the cerebello...
