    the right leg or hip area and he could not tell us if he was having pain in that area. We also looked at his lab values for alkaline phosphatase which were elevated. We next sent him out for a bone scan. A 3-phase‚ radionuclide bone scan using technetium-99m methylene diphosphonate remains the criterion standard for detecting early heterotopic ossification. The examination consists of a radionuclide angiogram followed by a blood pool image over the suggestive site. A

    Yafaa Chaudhary PHYSICS 5 NOTES Physics 5 3.5.1 Radioactivity Evidence for the nucleus Qualitative study for the Rutherford scattering. Rutherford directed a narrow beam of α-particles‚ all of the same kinetic energy‚ in an evacuated container at a thin gold film‚ in order to identify the structure of an atom:  The α-particles need to be of the same kinetic energy otherwise slow α-particles would be deflected more than faster α-particles on the same initial path.  The container needs to be evacuated

    Wea`am Mohammad Al-jarie Dr. mokhleed zaza physics Medical applications of x-ray Introduction: X-radiation (composed of X-rays) is a form of electromagnetic radiation. X-rays have a wavelength in the range of 0.01 to 10 nanometers‚ corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×1016 Hz to 3×1019 Hz) X-rays up to about 10 keV (10 to 0.10 nm wavelength) are classified as "soft" X-rays‚ and from about 10 to 120 keV (0.10 to 0.01 nm wavelength) as "hard" X-rays‚ due

    APPENDICITIS Reporter: Rita May C. Reyna APPENDIX The appendix is a normal true diverticulum of the cecum. Like any diverticulum‚ it is prone to acute and chronic inflammation‚ and acute appendicitis is a relatively common entity. Other lesions‚ including tumors‚ can also occur in the appendix but are far less common. The appendix is a wormlike extension of the cecum and‚ for this reason‚ has been called the vermiform appendix. The average length of the appendix is 8-10 cm (ranging from 2-20
