“…The excretion of 99m Tc-pertechnetate is not dependent on the presence of parietal (acid-producing) cells (8)(9)(10). Avid accumulation of 99m Tc-pertechnetate in gastric mucosa makes scintigraphy with 99m Tc-pertechnetate the study of choice for identifying ectopic gastric mucosa in a Meckel diverticulum.…”

“…These areas corresponded to the space filled by the active gastric juice, which also verified the observations of Irvine et al concerning the 'fundal pool". It was not possible to explain why the above sign, first observed by Harden [9], was found to be predom inant in the case of sliding hernia.…”

“…21 after the resection of the stomach). Harden [9] mentioned th at this may be the way to show the presence of Meckel's diverticulum containing the aberrant tissue of the gastric mucosa. As the above diverticuli are found in about 1 to 3% of all cases ami, as in more than half of them the mucosa has a similar structure to that of the stomach [8], the examination with " mTc is of high potential use, particularly so as the diverticuli are often difficult to detect radiologically.…”

Technetium-99m, after i. v. administration, is found to be localized in the gastric mucosa, and is subsequently excreted with the stomach juice. Owing to the favorable physical properties of ^99mTc, satisfactory scans of the stomach can be made. The presence of neoplasms is shown as areas of lower density of scans. No alcerations or inflammatory processes, however, can be visualized with this method. The technique of obtaining ^99mTc and the scanning procedure are presented.

“…10 The Pertechnetate ion is removed by various organs and systems into the interstitial liquid, as seen in the stomach, thyroid, salivary glands, bowel, choroid plexus, kidneys, vascular structures and mucosae. 11 Interestingly, the pertechnetate ion is strongly taken up by the thyroid gland only in its free form and not bound to other molecules. 12 Noticeably, lungs represent a transit organ for 99m TcO 4 -and its temporal concentration peak declines along the 30 min of the scintigraphic observation and this pattern is very similar also for other various organs.…”

The aims of this study were to assess extemporaneous in vivo binding between 99m TcO 4 -and two sclerosant detergents in foam sclerotherapy, and subsequently to control any possible damage in lungs and other organs related to sclerosant foam passage. A prospective comparative pilot study was performed on two male patients (62 and 56 years old) affected by varicose veins; each of them underwent scintigraphy investigations with free radiotracer and a scintigraphy investigation after each of the four sessions of sclerotherapy of varicose tributaries of the lower limbs with labeled sclerosant foam. One of the two patients underwent two further scintigraphic investigations, with free radiotracer and with labeled sclerosant foam, at a later stage. Four mL of 2% polidocanol (POL) foam, or four mL of 1% sodiumtetradecylsulfate (STS) foam for session were injected. The sclerosant foam was labeled with the radioactive tracer technetium pertechnetate, 99m TcO 4 -(120 MBq per exam). Two scintigraphy assessments for free tracer (basal) and five scintigraphy investigations of bound-tosclerosant tracer uptake/transit were obtained. No relevant variations in time/activity curves of the lungs and other organs were documented between the basal and post-sclerotherapy findings, also at the later stage. Free radiotracer mean region-of-interest data were: 336 counts (heart), 208 counts (lungs) and 371 counts (thyroid). Mean values extrapolated from each curve at each step for labeled CO 2 O 2 -based sclerosant foam were respectively: 351 counts (POL) and 328 counts (STS) for heart, 202 counts (POL) and 188 counts (STS) for lungs, 335 (POL) and 263 (STS) for thyroid. No pulmonary damage by sclerosant foam was caused. Neither immediately after treatments, nor at short-term follow-up.
