introduction: urinary obstructive disease is one of the most common disorders in urinary system. dilatation which is detected by sonography, is a key finding in obstruction in most of the cases, also could be found following surgery, lithotripsy and vesico–urethral reflux. radioistope diuretic washout renography is a useful method to differentiate mechanical and non mechanical obstruction. mate...

The rising incidence of breast cancer worldwide has prompted many improvements to current care. Routine nuclear medicine is a major contributor to a full gamut of clinical studies such as early lesion detection and stratification; guiding, monitoring, and predicting response to therapy; and monitoring progression, recurrence or metastases. Developments in instrumentation such as the high-resolu...

  Today, nuclear medicine has rapidly been developed so that in some cases, plays a unique role in diagnosis but unfortunalty in spite of diagnostic and therapeutic advantages, the term “NUCLEAR” can induce worries in patients and society. In this article, base on new documents, we intend to show that this worries has no scientific basis. To produce a realistic view, ...

UNLABELLED In the daily practice of in-hospital or centralized radiopharmacies, there is a need to perform reliable numeric calculations. Furthermore, several nuclear medicine diagnostic tests also involve carrying out calculations. In both cases, these calculations are sometimes complex or tedious and prone to error. We report the development of a computer software program that performs a comp...

Introduction In nuclear medicine, diagnostic imaging displays the metabolic function of the human body. The radiopharmaceuticals enable cancer imaging as unbound isotopes or simple compounds, non target tracers, target tracers and target cancer radiopharmaceuticals (1). Molecular imaging strategies of PET radiopharmaceuticals and combined technology of PET-CT have a major role in oncology today...

Introduction: Nowadays, nuclear medicine (NM) imaging indications in medical practice is raising. A practical step to get closer to the optimization rule is collecting data about patients’ exposure and definition of guidance levels. The aim of this study was definition of local reference level in Isfahan city. Materials and Methods: Questionnaires were given...

Nuclear medicine is a rapidly growing discipline that employs advanced novel hybrid techniques that provide unique anatomical and functional information, as well as targets for molecular therapy. Concomitantly, there has been an increase in the attention paid to medical radiation exposure. A radiological justification for the practice of nuclear medicine has been implemented mainly through refe...
