Isotope Techniques in the Investigation of Diseases of Joints

Investigation of joint disease

“…Depending on the site, bone mineral content can be measured using single or dual photon absorptiometry, but this technique is more useful for population-based studies of risk factors than in the management of individual patients. Baker's cyst can be demonstrated either by direct intra-articular injection of a non-absorbed tracer such as sulphur colloid (AbdelDayem et al 1981) or with intravenous pertechnetate (Merrick 1989). The intra-articular technique has never gained general acceptance, as better anatomical detail can be obtained with intra-articular water-soluble radiographic contrast media or ultrasound, both of which in turn are being superseded by MRI.…”
