Nuclear Medicine - Research Paper Example r radionuclide, which is in a bond with a supplementary molecules (such as, peptide, protein, or drug) or particles, that cumulates in the required tissue or organ after introducing it in the patient’s body through inhalation, swallowing, or injection (National Research Council, 2007). Depending on the characteristics, different radiopharmaceuticals are used for different diagnosis and treatment processes. Radiopharmaceuticals generally discharge beta or alpha radiation. As beta and alpha radiations are more effective than the gamma radiation that is used in diagnosis process, they are widely exploited in the most nuclear medicine procedures (National Research Council, 2007). The preparation of patients for nuclear medicine processes varies according to the type of examination or test. However, there are certain standard guidelines which are required to follow while preparing the patient to ensure the accuracy of tests. There is no need of special preparations for the scans associated with the inflammatory, bones, pulmonary, brain, lymphatic and renal systems (Patient Care, 2014). However, specific drug allergies are required to be noted by means of Diamox for brain scanning. For the scans associated with the gastrointestinal system, patients are required to fast for at least 4-5 hours (Patient Care, 2014). Some such scanning tests need pre-medicating as a part of a preparation. Further, cardiac tests consist of fasting of at least 4-5 hours prior to the test and persantine stress test need no consumption of caffeine for at least 24-30 hours before the test (Patient Care, 2014). Thyroid scanning needs pause on the consumption of specific medications befo re the scanning. Also, patients are required to inform their physician about the own medical history and present medications before going through the nuclear medicine procedures (Patient Care, 2014). Nuclear medicine is a painless, affordable, and safe mode of collecting medical data that would be otherwise

How does technology make money - Essay Example MOST is a technology that employs high speed multimedia network which facilitates common devices like PDA, DVD, radio and many others for the purpose of getting used by them at the lowest cost. The common devices can connect with this network to provide functionality to the end consumers to avail live audio and video having a standardized interface. It provides extendibility and reliability to the devices. Extendibility in the sense that more standardized devices can be easily added to the MOST networks without problems. MOST devices are connected using a ring which feeds the output to the input of the device in a circular manner. The token which travels in the network is a frame which contains streaming data segment, packet data and control information (MOST, 2008). The streaming data flows in the ring at the same speed the network is running. The synchronous feature of the data flowing in the network is at the same speed and retains the quality of the data. However packet data is non-synchronous in nature and may flow in several frames. The amount of streaming data and packet data forms a larger portion of the frame and the ratio is according to the application requirements. Control data on the other hand forms a little portion of the frame and contain the control information. It signals of the information into parts, in every frame so that it is grouped and regrouped by the receiving device for the knowledge of the placement of segment and packet data. Reliability compounds to the workability of the devices so that any device following the standard TCP/IP protocol. The reusability feature would enhance the functionality as more devices with a HMI (Human Machine Interface) can interact with each other for using the multimedia features. MOST was quite different concept to sharing of real time multimedia data over the
