Re-188 is useful candidate for therapeutic radionuclide because it has a physical half life of 17 hours, contains beta ernissions suitable for therapy(maximum energy 2.12MeV) and emits a garnma ray that is suitable for quantitative diagnostic scanning(155keV). To use He-188 as a radionuclide compound of angioplasty balloon radiotherapy, we investigated the labelling method and biodistribution of Re-188- DTPA. We postulated that labeled Re-188-DTPA is preferable because it would be excreted via urinary system more easily than other compounds. To label Re-188 with DTI'A, 1ml of 222MBqI(6mCi) of Re-188 was added to DTPA solution(DTPA 20mg, SnC4 2HsO 10mg, pH 3.5) and boiled at 100C for 120min in water bath. pH was adjuted to 5 with 2.3Fo sodium acetate. I.abeling efficiency was measured using TLC-SG(acetone, saline). We evaluated biodistribution of Re-188-DTPA in sacrificed mice at 10 and 60 minutes after injection. We acquired images of kidneys, and drew tirne-activity r.urves in normal dogs and rats and calculated Trnax and Tl/2 in rats. The labelling efficiency was 95.7Yo on average. Labelling of Re-188-DTPA was stable(90% after 5hours) in vitro at room temperature. According to time-activity curves of dogs and rats, it took 15 to 20 minutes after injection for Re-188-DTPA to be washed out through kidneys. In conclusion, Re-188-DTPA was successfully labeled, Re-188-DTPA was stable in vitro and was excreted early via kidneys in animals. We could recornmend Re-188-DTPA as radionuclide of potential use in angioplasty balloon radiotherapy.

N/A Attenuation correction is important in producing quantitative positron emission tomography (PET) images. Conventionally, photon attenuation effects are corrected using transmission measurements performed before tracer administration. The pre-injection transmission measurement approach may require a time delay between transmission and emission scans for the tracer studies requiring a long uptake period, about 45 minutes for F-18 deoxyglucose study. The time delay will limit patient throughput and increase the 1ikelihood of patient motion. A technique for performing simultaneous transmission and emission scans (T+E method) after the tracer injection has been validated. The T+E method substracts the emission counts contaminating the transmission measurements to produce accurate attenuation correction coefficients. This method has been evaluated in experiments using a cylindrical phantom filled with background water (5750 cc) containing 0.4 μCi/cc of F-18 fluoride ion and one insert cylinder (276 cc) containing 4.3 μCi/cc. GE AdvanceTM PET scanner and Ge-68 rotating pin sources for transmission scanning were used for this investigation. Post-injection transmission scan and emission scan were performed alternatively over time. The error in emission images corrected using post-injection transmission scan to emission images corrected using post-injection transmission scan to emission images corrected transmission scan was 2.6% at the concentration of 1.0 μCi/cc. No obvious differences in image quality and noise were apparent between the two images. The attenuation correction can be accomplished with post-injection transmission measurement using rotating pin sources and this method can significantly shorten the time between transmission and emission scans and thereby reduce the likelihood of patient motion and increase scanning throughput in PET.

N/A A series of performance measurements of positron emission tomography (PET) were performed following the recommendations of the Computer and Instrumentation Council of the Society of Nuclear Medicine and the National Electrical Manufacturers Association. We investigated the performance of the General Electric AdvanceTM PET. The measurements include the basic intrinsic tests of spatial resolution, scatter fraction, sensitivity, and count rate losses and randoms. They also include the tests of the accuracy of corrections: count rate linearity correction, uniformity correction, scatter correction and attenuation correction. GE AdvanceTM PET has bismuth germanate oxide crystals (4.0mm transaxial × 8.lmm axial × 30.0mm radial) in 18 rings, which form 35 imaging planes spaced by 4.25mm. The system has retractable tungsten septa 1mm thick and 12cm long. Transaxial resolution was 4.92mm FWHM in 2D and 5.14mm FWHM in 3D at the center. Average axial resolution in 2D decreased from 3.91mm FWHM at the center to 6.49mm FWHM at R=20cm. Average scatter fraction of direct and cross slices was 9.57%. Dead-time losses of 50% corresponded to a radioactivity concentration of 4.86μCi/cc and a true count rate of 519 kcps in 2D. The accuracy of count rate linearity correction was 1.84% at the activity of 4.50μCi/cc. Non-uniformity was 2.06% in 2D and 2.93% in 3D. Remnant errors after scatter correction were 0.55% in 2D and 4.12% in 3D. The errors of attenuation correction were 6.21% (air), 0.20% (water), -6.32% (teflon) in 2D and 5.00% (air), 6.94% (water), 3.01% (teflon) in 3D. The results indicate the performance of GE AdvanceTM PET scanner to be well suited for clinical and research applications.

N/A For estimation of regional myocardial blood flow with O-15 water PET, a few modifications considering partial volume effect based on single compartment model have been proposed. In this study, we attempted to quantify the degree of heterogeneity and to show the effect of tissue flow heterogeneity on partition coefficient(λ) and to find the relation between perfusable tissue index(PTI) and λ by computer simulation using two modified models. We simulated tissue curves for the regions with homogeous and heterogenous blood flow over a various flow range(0.2-4.0ml/g/min).Simulated heterogeneous tissue composed of 4 subregions of the same or different size of block which have different homogeneous flow and different degree of slope of distribution of blood flow. We measured the index representing heterogeneity of distribution of blood flow for each heterogeneous tissue by the constitution heterogeneity(CH). For model I, we assumed that tissue recovery coefficient (FMME) was the product of partial volume effect(FMMF) and PTI. Using model I, PTI, flow, and FMM were estimated. For model II, we assumed that partition coefficient was another variable which could represent tissue characteristics of heterogeneity of flow distribution. Using model II PTI, flow and λ were estimated. For the simulated tissue with homogeneous flow, both models gave exactly the same estimates of three parameters. For the simulated tissue with heterogeneous flow distribution, in model I, flow and FMM were correctly estimated as CH was increased moderately. In model II, flow and λ were decreased curvi-linearly as CH was increased. The degree of underestimation of λ obtained using model II, was correlated with CH. The degree of underestimation of flow was dependent on the degree of underestimation of λ. PTI was somewhat overestimated and did not change according to CH. We conclude that estimated λ reflect the degree of tissue heterogeneity of flow distribution. We could use the degree of underestimation of λ to find the characteristic heterogeneity of tissue flow and use λ to recover the underestimated flow.

This paper is the last report on the Li-fragments emitted from the nuclear reactions caused by 28-GeV protons in Ilford G-5 nuclear emulsion. The first was on the slow Li-fragments (E<60-MeV), which seemed to be emitted according to the evaporation theory. The second was on the Li-fragments (E≥60-MeV). Their energy and angular distributions were analysed and it was concluded that they were ejected by cascade model. This report, the last, is also on the fast Li- fragments. Here, the probability of ejection of a fast fragment (Z≥3) as a function of n_b or n_g or n_s which is the number of black, grey and schower tracks respectively, and the charge distribution of the fast fragments (Z≥3) were obtained. An analysis of this data once again gives the same conclusion that the fast Li-fragments are ejected by cascade model.
