Sadegh Nezam-mafi
Dr. Sadegh Nezam-mafi ( fa, صادق نظاممافی, 1925 in Tehran – 2009 in Tehran) was an Iranian physician and a pioneer of nuclear medicine in Iran. He introduced nuclear endocrinology to the country in 1960 with a thyroid probe and a rectilinear scanner A rectilinear scanner is an imaging device, used to capture emission from radiopharmaceuticals in nuclear medicine.

Tehran
Tehran (; fa, تهران ) is the largest city in Tehran Province and the Capital city, capital of Iran. With a population of around 9 million in the city and around 16 million in the larger metropolitan area of Greater Tehran, Tehran is the List of largest cities of Iran, most populous city in Iran and Western Asia, and has the Largest metropolitan areas of the Middle East, second-largest metropolitan area in the Middle East, after Cairo. It is ranked 24th in the world by metropolitan area population. In the Classical antiquity, Classical era, part of the territory of present-day Tehran was occupied by Ray, Iran, Rhages, a prominent Medes, Median city destroyed in the medieval Muslim conquest of Persia, Arab, Oghuz Turks, Turkic, and Mongol conquest of Khwarezmia, Mongol invasions. Modern Ray is an urban area absorbed into the metropolitan area of Greater Tehran. Tehran was first chosen as the capital of Iran by Agha Mohammad Khan Qajar, Agha Mohammad Khan of the Qajar dyn ...

Nuclear Medicine
Nuclear medicine or nucleology is a medical specialty involving the application of radioactive substances in the diagnosis and treatment of disease. Nuclear imaging, in a sense, is "radiology done inside out" because it records radiation emitting from within the body rather than radiation that is generated by external sources like X-rays. In addition, nuclear medicine scans differ from radiology, as the emphasis is not on imaging anatomy, but on the function. For such reason, it is called a physiological imaging modality. Single photon emission computed tomography (SPECT) and positron emission tomography (PET) scans are the two most common imaging modalities in nuclear medicine. Diagnostic medical imaging Diagnostic In nuclear medicine imaging, radiopharmaceuticals are taken internally, for example, through inhalation, intravenously or orally. Then, external detectors ( gamma cameras) capture and form images from the radiation emitted by the radiopharmaceuticals. This ...

Endocrinology (from ''endocrine'' + '' -ology'') is a branch of biology Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field.

Rectilinear Scanner
A rectilinear scanner is an imaging device, used to capture emission from radiopharmaceuticals in nuclear medicine. The image is created by physically moving a radiation detector over the surface of a radioactive patient. It has become obsolete in medical imaging, largely replaced by the gamma camera since the late 1960s. History One of the first rectilinear scanners was developed by Benedict Cassen in 1950. Before then hand-held detectors had been used to locate radioactive materials in patients, but the Cassen system (designed for Iodine-131) combined a motor driven photomultiplier tube and printing mechanism. Subsequent developments improved the detection systems, movement, display and printing of images. Components Cassen's original rectilinear scanner used calcium tungstate (CaWo4) crystal as the radiation detector. Later systems used a Sodium iodide (NaI) scintillator, as in a gamma camera. The detector must be connected by mechanical or electronic means to an outp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Year Of Birth Uncertain
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Pittsburgh Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic Church monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word ''universitas'' (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hild ...
