gamma camera is an important apparatus in nuclear medicine imaging. its detection part is consists of a scintillation detector with aheavy collimator. substitution of semiconductor detectors instead of scintillator in these cameras has been effectively studied. in this study, it is aimed to introduce a new design of p-n semiconductor detector array for nuclear medicine imaging. a p-n semiconduc...

Aim: Few nuclear cardiology surveys were published in the literature, mostly from developed countries. The aim of this study is to perform a nuclear cardiology survey in Iran. This may lead to better decision making and programming. Methods and Materials: A questionnaire was sent by mail or e-mail to all nuclear medicine centers in Iran asking for details of nuclear cardiology practice in...

Unsealed radioactive sources such as 131I and 99mTc are used in Nuclear Medicine Centers, to diagnose and treat patients, pose significant risks of internal exposure to the occupational workers. 131I is highly volatile and radiotoxic, which may pose an occupational radiological hazard, especially in places where significant activities are routinely handled. In such situations, worker handling u...

The widespread adoption of high dose rate brachytherapy with its inherent dangers necessitates adoption of appropriate quality assurance measures to minimize risks to both patients and medical staff. This paper is aimed at assisting someone who is establishing a new program or revising one already in place into adhere to the recently issued Nuclear Regulatory Commission (USA) regulations and th...

  Solitary pulmonary nodule (SPN) is a frequent finding on the chest x-ray and computed tomography. Nuclear medicine techniques play an important role in the diagnosis and management of SPN. In the current review, we briefly will explain the different nuclear medicine modalities in this regard including positron emission tomography (PET) using 18-F-FDG, and 11-C-Methionine, and single photon em...

The aim of this study was to provide data on genetic hazards associated with occupational exposure to low doses of ionising radiation in nuclear medicine departments. The DNA damage in peripheral blood lymphocytes of medical staff was assessed using the chromosome aberration test. Altogether 120 subjects (60 exposed and 60 controls) participated in the study. The exposed subjects showed signifi...

Presented paper describes the results of the individual doses measurements for ionizing radiation, carried out by the Laboratory of Individual and Environmental Doses Monitoring (PDIS) of the Central Laboratory for Radiological Protection in Warsaw (CLOR) for the medical staff employees in several nuclear medicine (NM) departments across Poland. In total there are48 NM departments in operation ...

OBJECTIVES To investigate radiation exposure among the staff of departments of nuclear medicine (NM) and diagnostic radiology (DR) during 2008 and 2009 and to compare the mean doses received with the limit of 20 mSv/year of the International Commission of Radiological Protection (ICRP). MATERIALS AND METHODS The whole-body dose or effective dose, i.e. Hp(10), and the skin dose, i.e. Hp(0.07),...
