If more than one radionuclide is to be used generic acarbose 50mg line, the highest hazard category determined should be applied cheap 25mg acarbose visa. The radiation protection requirements for each hazard category are given in Table 3 purchase acarbose 50mg fast delivery. The design of equipment and the associated appli- cations software have evolved rapidly and buy discount acarbose 25 mg line, to some extent order acarbose 50mg online, continue to be developed. Selection criteria should include flexibility in use, reliability and backup, with features determined by the desired function. It is important to ensure that equipment is specified to meet full requirements and, where possible, contractual conditions are in place to ensure the performance of the delivered system, as confirmed during acceptance testing. Nuclear medicine instruments are particularly sensitive to environmental conditions and conse- quently require strict control of temperature and humidity, as well as a continuous and stable power supply. Regular assessment is required to confirm stable operation using the quality control testing that is achievable in practice. All three aspects (specifications, acceptance testing and routine quality control) are important to ensure effective clinical operation. There are well established criteria for specifi- cation and testing of single photon instrumentation; however, the dual photon imaging field has only developed recently with the introduction of relatively inexpensive coincidence circuits for dual head gamma cameras. The miscellaneous other equipment tends to utilize well established technology, even in the case of relatively new innovations (e. It is beyond the scope of this publication to provide a comprehensive coverage of instrumen- tation. The manual offers introductory information that may provide the reader with an improved understanding of performance specification and testing, referring the reader to more specific texts that can be used for a more detailed study. General considerations The following factors should be considered when purchasing nuclear medicine imaging equipment. An appropriate configuration should be selected to best match the desired end application, bearing in mind that the system may need to be used for other functions at some future date. The availability of specific features, software or accessories that meet the defined function is likely to be one of the main deciding factors in selecting a suitable system. Service availability It is critically important that there be demonstrated service capability in the country and a guaranteed support for the system. In considering the overall cost of a system, maintenance contract costs should be included and considered essential. Competition between companies usually results in very similar specifications, so much so that other factors generally determine the system of choice. Demonstrated capability Care should be taken in selecting completely new designs, as it is common with new systems for problems to manifest themselves that will be resolved in later models. Users should be consulted on the performance of previously installed systems of the same design. Ease of upgrade It is important that systems can be easily upgraded and that software can be updated for several years after purchase. Compatibility In some circumstances, the system purchased should be compatible with existing systems in the department. Advantages include the familiarity of staff with operation, sharing of accessories and proven availability of support. Provision for transferral of data between systems and general networking has increasing importance. Ease of use Ideally, the system should be easy to use, with manual override available for any automatic features (e. Selection of accessories A wide range of accessories is normally available, but should be chosen to meet anticipated needs. However, there are instances where increased cost may be justified in terms of more effective use of the equipment. Contractual considerations When purchasing an imaging system it is imperative that a document be prepared that not only defines the requirements of the system to be purchased but also clearly outlines the obligations placed on both the supplier and the receiving institution. In addition to the specification sheets made available by the vendors, the user should also consider the main studies to be performed on the camera and the specifications necessary to obtain optimal clinical results. Complete operation and service manuals should be supplied with the gamma camera and should remain the property of the user. Appropriate radiation sources and phantoms needed for quality control tests should be purchased at the time of instrument acquisition. Results of acceptance tests, performed immediately after installation, will be compared with these data. Most acceptance tests should be performed by the supplier, under the supervision of, and in cooperation with, a suitably experienced nuclear medicine physicist. All phantoms and test equipment required for acceptance testing should be made available free of charge by the supplier. A clause built into the purchase agreement should specify the procedures to be used during acceptance testing, minimum acceptable results and actions to be taken if acceptance test results do not meet pre-purchase agreements.

The disease primarily involves the synovial components of the sacroiliac joints and the cartilaginous discovertebral junctions as well as the apophyseal order acarbose 50mg on line, costovertebral and neurocentral joints of the vertebrae buy discount acarbose 50 mg on-line. Planar bone scintigraphy reveals symmetric intense tracer uptake in the sacroiliac joints and/or spine 25 mg acarbose sale. Pinhole scintigraphy can portray the characteristic ribbon-like tracer uptake in the synovial joints of the spine acarbose 50mg low cost, producing a ‘bamboo spine’ appearance generic 25mg acarbose otc. In the late stage, tracer uptake becomes reduced, reflecting a quiescent metabolic state. The disease mechanism is still obscure, but an interaction between several different infective organisms and a specific genetic background is currently being given serious consideration. Pathologically, the main alterations are present in the enthesis, which is the site of insertion of a tendon, ligament or articular capsule into the bone, creating characteristic inflammatory enthesopathy. Conspicuous involvement of entheses in this syndrome sharply contrasts with the dominant involvement of the synovium in rheumatoid arthritis. The whole body scan can panoramically reveal characteristic asymmetrical pauciarticular involvement of the spine and appen- dicular bones and joints. Pinhole scintigraphy often detects characteristic enthesopathy in the pre-radiographic stage, especially in the heel and knee. In addition, pinhole scintigraphy can show specific signs of Reiter’s syndrome, namely the ‘knuckle bone’ sign of the sausage digit, the ‘teardrop’ sign of paravertebral enthesopathy and the ‘whisker’ sign of periarticular hyperostosis. It is a rheumatic disorder of clinical importance and academic interest, often related to previous trauma. The pathogenesis has not yet been clarified, although the theory of the internuncial pool is widely accepted. The identification of the ‘sympathetic vasoactive intestinal peptide-containing nerve fibres’ at the cortical bone and the bone–periosteal junction has provided a biochemical basis for the theory. Three phase scintigraphy is useful, revealing increased blood flow and blood pooling, which denotes hyperperfusion. Involvement of periarticular structures of one or more joints of a limb is characteristic. The common causes include trauma, embolism, thrombosis, elevated bone marrow pressure, irradiation and vasculitis. Scintigraphically, avascular necrosis presents as a hot area on the planar image, especially in small bones. However, when magnified using pinhole scintigraphy, a photopenic area can be detected within the hot area. Typical examples are avascular osteonecrosis of the femoral head and of the internal femoral condile of the knee. Common clinical features include a predilection for actively growing bone, chronic exposure to trauma and local pain, and tenderness. Osteochondroses affect the capital femoral epiphysis (Legg–Calvé– Perthes disease), the tarsal navicular bone (Koehler’s disease), the metatarsal head (Freiberg’s disease), the medial clavicular end (Friedrich’s disease), the secondary ossification centres of the vertebrae (Scheuermann’s disease) and the tibial tubercle (Osgood–Schlatter’s disease). Large avascular osteonecrosis produces cold areas, whereas microfractures or bone infraction are represented by hot lesions. Scintigraphy can provide information regarding the size, shape, location, texture and osteochondral junction pattern, frequently leading to specific diagnosis. In elderly patients, it is useful for the study of contusion and fracture in osteoporotic ribs and spine. Bone scintigraphy is valuable for the detection and differential diagnosis of shin splints and stress fractures. It can be used for the classification of stress fractures, showing the characteristic tracer uptake in the absence of radiographic alteration. Usually, a planar whole body scan and spot images are sufficient for the diagnosis of a fracture. Occasionally, however, magnification is needed for accurate locali- zation of the fracture, differential diagnosis between bruise and fracture, and detection of an occult fracture. Bone scintigraphy reinforced with pinhole magnification can portray tracer accumulation in sites specific to the individual diseases. For example, in Achilles tendinitis the tracer accumulates in the upper retrocalcaneal surface. Bone scintigraphy is useful for the demon- stration of bone tracer accumulation in denatured or calcified muscle fibres and musculotendinous units. Bone scintigraphy aided by pinhole magnification is useful to delineate the individual structures affected. This presentation describes involutional osteoporosis, osteomalacia, rickets and renal osteodys- trophy, all of which can be diagnosed by scintigraphy. In post-menopausal osteoporosis, trabecular bone mass is disproportionately reduced in comparison with cortical bone mass. On the other hand, senile osteoporosis is characterized by the propor- tionate loss of cortical and trabecular bone.
