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...

  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...

ABTRACT Background: In nuclear medicine, phantoms are mainly used to evaluate the overall performance of the imaging systems and practically there is no phantom exclusively designed for the evaluation of the software performance.  In this study the Hoffman brain phantom was used for quantitative evaluation of reconstruction techniques. The phantom is modified to acquire t...

Although assessing myocardial viability is a common cardiology practice, many physicians question the results of diagnostic methods. Nuclear medicine plays an important role in studies, but reports require interpretation clinical and pathophysiological context. this article was aimed at reviewing origin evolution viability. Here we present methods by emphasizing nuclear provide functional expla...

Medical imaging is often thought of as a way of viewing anatomical structures of the body. Indeed, x-ray computed tomography and magnetic resonance imaging yield exquisitely detailed images of such structures. It is often useful, however, to acquire images of physiologic function rather than of anatomy. Such images can be acquired by imaging the decay of radioisotopes bound to molecules with kn...

This article was written to give health-care providers working in the field of nuclear medicine some background information on pediatric PET/CT. Specifically, it provides information regarding patient preparation and acquisition techniques necessary to obtain high-quality pediatric PET/CT images. It is targeted primarily at nuclear medicine technologists and CT technologists but may be benefici...

Introduction: Acquiring a high quality image has assigned an important concern for obtaining accurate diagnosis in nuclear medicine. Detector and collimator are critical component of Single Photon Emission Computed Tomography (SPECT) imaging system for giving accurate information from exact pattern of radionuclide distribution in the target organ. The images are strongly affect...

Obesity, with its alarming increase among adults and children, represents a significant health problem with serious medical, social, psychologic, and economic reverberations. The burden of this problem significantly affects the medical care system, including medical imaging. The effect of obesity on nuclear medicine imaging spans many aspects, from preimaging patient preparation to radiotracer ...
