Background: This study aimed to investigate dose area product (DAP), effective dose, and radiation risk in newborn infants hospitalized in neonatal intensive care units in Isfahan and Kashan. Materials and Methods: During a period of six months, DAP for chest X-ray examinations for newborn infants hospitalized in NICUs of five special hospitals including Beheshti (in Kashan), Al-Zahra, Imam Hos...

Background: Application of Dose-area product (DAP) quantity has been increased in the clinical practice. DAP is relatively easy to measure. DAP has been shown to correlate well with the total energy imparted to the patient, which is related to the effective dose. Material and Methods: In this study, measurements of DAP were carried out in a sample of 421 adult patients who underwent convention...

BACKGROUND Image guidance for spine pain control procedures, including epidural steroid injection, nerve root block, and facet block, can be performed with either computed tomography (CT) or conventional fluoroscopy. CT has the advantage of improved anatomic localization and use of air for contrast; however, there are concerns that CT leads to higher radiation dose and longer procedure time. ...

Purpose: The increase in the medical and industrial uses of radiation last century has caused people to be exposed higher doses radiation. Although harms high-dose on human health are known, effects low-dose have not yet been fully elucidated. In this study, we aimed investigate DNA damage lymphocytes patients with lung, pleura/thoracic wall masses planned for percutaneous thoracic mass biopsy ...

Background: In the past several years, emerging imaging techniques, such as computed tomography angiography (CTA), Doppler ultrasound, and magnetic resonance (MRI), have been used for investigating anatomy perfusion of perforator complexes. Preoperative CTA can provide explicit information on flaps, which not only helps surgeons to evaluate optimal design flaps with respect lateral circumflex f...
