For practical reasons buy cheap sildigra 120 mg on-line, only single counts are obtained on radioactive samples instead of multiple repeat counts to determine the mean value buy 120mg sildigra otc. In this situation effective sildigra 25 mg, if a single count n of a radioactive sample is large, then n can be estimated as close to ;n that is, n = n and s = n. It can then be said that there is a 68% chance that the true value of the count falls within n ± s or that the count n falls within one standard deviation of the true value (Fig. That is, one is 68% conﬁdent that the count n is within one standard deviation of the true value. Similarly, 95% and 99% conﬁdence levels can be set at two standard deviations (2s) and three standard deviations (3s), respectively, of any single radioactive count. Another useful quantity in the statistical analysis of the counting data is the percent standard deviation, which is given as s 100 n 100 %s 100 (4. Thus, the precision of a count of a radioactive sample can be increased by accumulating a large number of counts in a single measurement. Answer 95% comﬁdence level is 2s, that is, 2 n 2s × 100 2 n × 100 2% = = n n Therefore, 200 2 = n n = 100 n = 10,000 counts Propagation of Errors 37 Standard Deviation of Count Rates The standard deviation of a count rate is s sc = t where s is the standard deviation of the total count n of a radioactive sample obtained in time t. Because n is equal to the count rate c times the counting time t, c sc n t ct t (4. Answer 8640 Count rate c 720 counts per minute cpm 12 Standard deviation, sc ct 720 12 8 Therefore, the count rate is 720 ± 8cpm. Propagation of Errors Situations arise in which two quantities, say x and y, with their respective standard deviations, sx and sy, are either added, subtracted, multiplied, or divided. The standard deviations of the results of these arithmetic opera- tions are given by the following expressions: Addition: s (4. Calculate the net count rate, its standard deviation, and percent standard deviation. Answer 8000 Gross sample count rate 1600cpm 5 3000 Background count rate 600cpm 5 Net count rate = 1600 − 600 = 1000cpm Using Eqs. The 2-min counts are: standard, 90,000; room background, 1000; thyroid, 40,000; and thigh, 2000. Answer Net standard count = 90,000 − 1000 = 89,000 s s 90,000 1000 = 302 Chi-Square Test 39 Net thyroid count = 40,000 − 2000 = 38,000 st 40,000 2000 = 205 Percent thyroid uptake 38,000 = 100 42 7. It should be noted that although all counts were taken for 2min, count rates (cpm) were not used in the calculations. Chi-Square Test 2 The chi-square (c ) test is a useful test for verifying if the variations in a set of measurements are due to statistical randomness of the data or due to variations in entities, such as equipment, patients, and the like, used in the measurements. The latter variations may be systematic, such as a ﬁxed voltage drop throughout the measurement or random, such as ﬂuctuations in voltage supply to the equipment. If there are N measurements made of a parameter, then for Gaussian distribution of the data, which is true in radioactive measurement, the c2 is given by N 2 i − c = ∑ (4. If the observed c2 value falls outside this range, it is an indication that the variation is beyond the statistical randomness of the data and something is wrong with the experimental set-up, for example, measuring equipment, measurement technique, and so on. In performing the c2 test, a number of measurements (a minimum of 10) are made of the quantity, and the mean and c2 of the measured values are 2 calculated by Eq. Use the c2 test to see if the variations in counts are due to statistical variations of radioactivity or the counter is not working properly. The computed c2 far exceeds the theoretical value, so something in addi- tion to the statistical ﬂuctuations of the counts is operating. Minimum Detectable Activity The efﬁciency of different detectors is limited by the dead time at high count rates and by statistical ﬂuctuations at low count rates of the back- grounds. Evaluation of Diagnostic Tests It is often required to evaluate the usefulness of a new diagnostic test to determine the presence or absence of a particular disease. This aspect of the test is commonly described by two entities: sensitivity and speciﬁcity. The sensitivity of a test is the probability of being able to identify correctly 42 4. By these deﬁnitions, it is obvious that a given test may not identify all patients correctly whether or not they have the disease. It should be noted that when sensitivity is assessed for a diseased popu- lation or speciﬁcity for a healthy group, the disease or healthy status of the group must be assessed by an established standard diagnostic test. This test is called the “gold standard” and is considered the best method available for comparison. Suggested Readings 43 Answer True positive = 780 True negative = 160 − 15 = 145 False negative = 840 − 780 = 60 False positive = 15 780 780 Sensitivity = 100 92 6. A radioactive sample gives 15,360 counts in 9min: (a) What are the count rate of the sample and its standard deviation? How many counts of a sample are to be collected to have a 1% error at the 95% comﬁdence level? To achieve an estimated percent standard error of 3%, how many counts must be collected? What is the prob- ability that the variations of measurements are due to statistical varia- tions of the quantity? The majority of radionuclides are arti- ﬁcially produced in the cyclotron and reactor. Some short-lived radionu- clides are available from the so-called radionuclide generators in which long-lived parents are loaded and decay to short-lived daughters. These accelerated particles can possess a few kiloelectron volts (keV) to several billion electron volts (BeV) of kinetic energy depending on the design of the cyclotron. Because charged particles move along the circular paths under the magnetic ﬁeld with gradually increasing energy, the larger the radius of the particle trajectory, the higher the kinetic energy of the particle. The charged particles are deﬂected by a deﬂector (D) through a window (W) outside the cyclotron to form an external beam. When targets of stable elements are irradiated by placing them in the external beam of the accelerated particles or in the internal beam at a given radius inside a cyclotron, the accelerated particles interact with the target nuclei, and nuclear reactions take place. In a nuclear reaction, the incident particle may leave the nucleus after interaction with a nucleon, leaving some of its energy in it, or it may be completely absorbed by the nucleus, depending on the energy of the incident particle. In either case, a nucleus with excitation energy is formed and the excitation energy is disposed of by the emission of nucleons (i. Particle emission is followed by g-ray emission when the former is no longer energetically feasible. Depending on the energy deposited by the incident particle, several nucleons are emitted randomly from the irradiated target nucleus, 44 Cyclotron-Produced Radionuclides 45 Fig. A and B, dees with vacuum; D, deﬂector; S, ion source; V, alternating voltage; W, window. As the energy of the irradi- ating particle is increased, more nucleons are emitted, and therefore a much wider variety of nuclides is produced.
