Radioisotope Stdy Of Salivary Glands

radioisotope stdy of salivary glands

Xerostomia, which is caused due to the damage of salivary glands, is one of the main radiation induced toxicities in post-radiotherapy head and neck patients. This review article discusses the methods for the assessing of radiation induced salivary gland changes including the gland morphology and saliva flow rate.

Radiation Induced Salivary Gland Damage: Review on ...

The most likely cause for this appears to be a blockage of the flow of the saliva out of the glands caused by a narrowing of the ducts and/or thickened saliva. The narrowing is the result of scarring due to inflammation caused by the radiation.

Today, salivary-gland function can be assessed by 99mTc pertechnate scintigraphy (SGS). Its diagnostic yield can be improved if it is performed before and after 131 I treatment, thus reducing interindividual variability. Information can be obtained by both 99mTc pertechnate uptake as well as by its release pattern from the salivary glands.

The following article is the second article in a 2-part series on infrequently performed studies in nuclear medicine. The procedures reviewed include CSF shunt imaging, brain death scintigraphy, testicular scanning, quantitative lung perfusion studies, lymphoscintigraphy, and salivary gland scintigraphy.

In this study, the oral radioactivity seen in salivary gland scintigraphy, which was established entirely on the basis of radioactive saliva secreted by the parotid and submandibular glands, was evaluated quantitatively in healthy volunteers and in patients with Sjögren’s syndrome.

Saliva & Salivary Gland Disorders Causes, Symptoms ...

as salivary glands As a result, I-131 can damage the salivary glands, which are very sensitive to radiation . Because of this, the radiation sialadenitis (salivary gland inflammation) and xerostomia (dry mouth) are the most common complications of I-131 therapy, which can even occur with small amounts of I-131 . Sour liquids, juices and drops with

Radioiodine-induced salivary gland damage detected by ...

Secondary aims were to study unstimulated whole and stimulated glandular (i.e., parotid and submandibular) saliva flow rate and composition alterations, development of xerostomia, characteristics of patients at risk for salivary gland dysfunction, and whether radioiodine uptake in salivary glands on diagnostic scans correlates to flow rate ...

To ascertain the real-time activity of the salivary glands, we performed a radioisotope study with technetium Tc 99m pertechnetate (TPT). A real-time/activity graph indicated that the left parotid gland failed to trap and secrete the TPT adequately ().The right parotid gland and the two submandibular glands demonstrated normal uptake and release of the TPT (Figures 1A and 1B, respectively).

The use of radioactive iodine has become an important adjunct to the treatment of thyroid cancer. Many normal tissues--including salivary glands, gastrointestinal mucosa, gonads, and lactating...

Olfaction, Radioactive Iodine, and Salivation | Natural ...

For most major salivary gland cancers, radiation is only given to the side of the face and neck with the cancer. This reduces the risk of serious long-term side effects. But in rare instances, both sides of your face and neck might need to be treated with radiation. This may damage other salivary glands, resulting in permanently dry mouth.

Salivary Gland Injury Resulting From Exposure to ...

BACKGROUND AND PURPOSE: Although radiation induced damage to the salivary gland is a known complication of radioactive iodine (131I) therapy for thyroid carcinoma, prediction of the severity and reversibility of sialoadenitis is difficult. Our aim was to correlate the extent of salivary dysfunction assessed by salivary gland scintigraphy with changes in the volume and attenuation of salivary ...

In this study, researchers at the Beijing Tiantan Hospital in China decided to explore the presence of nitrated alpha-synuclein in minor salivary glands of Parkinson’s disease patients.. To do so, eight patients with idiopathic (of unknown cause) Parkinson’s disease in the early clinical stages, including four men and four women at a mean age of 50.75 years, and seven age-matched healthy ...

You have been scheduled for a Salivary Gland study which involves the use of a small amount of radioactive material. The level of radioactivity used is extremely low and has no side effects. You will be positioned on an imaging table, under a special detector called a gamma camera. The camera does not produce any radiation.

Radioactive Iodine and the Salivary Glands | Thyroid

Quantitative studies have shown that radiation within the parotid decreased rapidly after induction of salivary gland secretion with lemon juice. 16 However, based on the absorbed dose equation described earlier, an increase in salivary flow after 131 I therapy should increase the total exposure of the salivary gland to radiation.

Amifostine for salivary glands in high‐dose radioactive ...

After radioiodine (RI) therapy, patients with thyroid cancer frequently suffer from painful salivary gland (SG) swelling, xerostomia, taste alterations, and oral infections. This study was aimed ...

Salivary Gland Injury Resulting From Exposure to ...

Abstract. Objective: Quantitative analysis of 99m Tc-pertechnetate salivary gland scintigraphy has been used in the evaluation of salivary gland function, but so far no one method can be considered optimal for this task. In this study, a semiquantitative method providing 2 functional parameters for objective assessment of salivary gland function by scintillation camera imaging was tested.

Radioactive Iodine (Radioiodine) Therapy for Thyroid Cancer

Abstract The use of radioactive iodine has become an important adjunct to the treatment of thyroid cancer. Many normal tissues--including salivary glands, gastrointestinal mucosa, gonads, and lactating breast tissue--have the ability to concentrate radioactive iodine under normal circumstances.

Scintigraphic Evaluation of Salivary Gland Dysfunction in ...

Salivary gland scintigraphy is widely accepted as a sensitive and valid method for evaluation of salivary gland dysfunction after Radioactive Iodine 131 Therapy (RIT). Aim To assess and compare the salivary flow rates, relative uptake and ejection fractions in parotid and submandibular glands just before and one month after Iodine 131 therapy.

Scintigraphic evaluation of salivary gland function in ...

Patients received salivary stimulation therapy with pilocarpine (5 mg, 3 times daily) over a 3-month period. Subjective symptom scores were assessed using self-reported questionnaires. Salivary flow rates (SFRs) were measured and salivary gland scintigraphy (SGS) was performed to evaluate objective salivary gland functions.

Although all salivary glands are involved in the transport of the radioactive iodine into the saliva, the parotid gland is most active and its serous cells are more susceptible than mucous acini to the deleterious effects of ionizing radiation.
