Medical radioisotope visualization (A review of “Scanning”)

Objective Symmetry Detector Method for Gammaencephalography Iii. Diagnosis of Abnormal99 Tcm O 4 distribution in the skull

“…The evaluation based on image interpretation is subjective and complicated, and demands great experience ( MALLARD 1966, BURROWS 1972.…”

Diagnostic Value of Routine Liver Scanning in Ecchinococcus Disease of the Liver; a Comparison of Scintigraphic and Surgical Findings in 100 Consecutive Cases

“…As shown by this study, in 66 out of the 100 cases the scan provided not only very strong supportive evidence for the clinical diagnosis of hydatid cysts, but also complete information as to the number, location and size of the cysts, while in another 24 cases the location of the cyst(s) and the total size of the cyst(s) were accurately predicted by the scan. One might reasonably expect that the introduction of new radioactive substances for liver scanning -such as 99m Tc -and the use of more sophisticated display techniques and/or new scanning machines (13,14) will increase both the accuracy of liver scintigraphy and the ratio of complete to relative agreement in hydatid cysts of the liver.…”

Renal scintiscanning. A review

“…Details of the physical aspects of scanning can be found elsewhere (Mallard, 1966(Mallard, , 1969 and the available instruments will be mentioned only briefly. The most widely used is the linear scanner in which a detecting crystal collimated to a small area moves continuously to and fro across the area being scanned, taking some 40 min to scan both renal areas.…”
