Quantitative assessment of dacryoscintigraphic images in the evaluation of epiphora.

Background: At the present time, only visual analysis is implemented on dacryoscintigraphic images and quantitative assessments are not routinely obtained. The authors have designed a novel, simple, quantitative method for the diagnosis of sac and post-sac obstructions based on the dacryoscintigraphic images.

Method: Fifty-nine patients with severe unilateral epiphora were included and the contralateral asymptomatic eyes were used as controls.

A simple way to distinguish bed clothing contamination in a whole body bone scan: a case report.

Whole body bone scan with Technetium-99m MDP (methylene diphosphate) can detect bony lesions due to altered osteoblastic activity.Non-physiologic or increased radiotracer uptake in the bony structures of patients with a history of malignant diseases is usually interpreted as being suspicious of bone metastasis. It is extremely important to properly distinguish false positive sites of Tc-99m MDP localization.

Consenting patients at reproductive age were grouped according to the cumulative dose of (131)I received and followed-up for at least 12 months. Overall, 246 patients (159 females, 87 males) were studied.

Incidental detection of malignant pleural effusion on sestamibi myocardial perfusion scan.

Incidentally the diagnosis of pleural effusions can be made with scintigraphic studies. We report a case of incidental detection of pleural effusion in sestamibi myocardial perfusion scan. A 64-year-old man with a history of chest pain was referred for Sestamibi myocardial perfusion scintigraphy.

Efficacy of radioiodine therapy in the treatment of elevated serum thyroglobulin in patients with differentiated thyroid carcinoma and negative whole-body iodine scan.

Introduction: In the management of patients with differentiated thyroid carcinoma, serum thyroglobulin levels are often well correlated with whole-body radioiodine scanning (WBS) results. However, occasionally, a mismatched result - increased thyroglobulin with negative WBS - is observed. Radioiodine therapy has been suggested as a therapeutic choice with controversial results.

The prevalence and significance of increased gastric wall radiotracer uptake in sestamibi myocardial perfusion SPECT.

Background: Limited available data indicate that a specific pattern of increased gastric wall radiotracer uptake is associated with dyspepsia. Our purpose was to evaluate the frequency of this finding and its relation with dyspeptic evidences.

Method: 1056 consecutive outpatients referred for myocardial perfusion SPECT were interviewed concerning the dyspeptic symptoms, current gastric medications and previous gastroduodenal interventions.

Frequency and severity of myocardial perfusion abnormalities using Tc-99m MIBI SPECT in cardiac syndrome X.

Background: Cardiac syndrome X is defined by a typical angina pectoris with normal or near normal (stenosis <40%) coronary angiogram with or without electrocardiogram (ECG) change or atypical angina pectoris with normal or near normal coronary angiogram plus a positive none-invasive test (exercise tolerance test or myocardial perfusion scan) with or without ECG change. Studies with myocardial perfusion imaging on this syndrome have indicated some abnormal perfusion scan. We evaluated the role of myocardial perfusion imaging (MPI) and also the severity and extent of perfusion abnormality using Tc-99m MIBI Single Photon Emission Computed Tomography (SPECT) in these patients.

The relationship between iron status and thyroid hormone concentration in iron-deficient adolescent Iranian girls.

Extensive data from animal and human studies indicate that iron deficiency impairs thyroid metabolism. The aim of this study was to determine thyroid hormone status in iron-deficient adolescent girls. By stepwise random sampling from among all public high schools for girls in Lar and its vicinity in southern Iran, 103 out of 431 iron deficient subjects were selected.

Unilateral absent lung ventilation and perfusion due to a hilar mass.

A 54 year old man was referred to us from his private physician for ventilation-perfusion lung scan. In both scans radiotracer activity was absent in the region of the right lung, while a prior chest X-rays film revealed no remarkable abnormality. Subsequent chest computed tomography revealed a hilar mass compressing the hilar vascular and bronchial area components.

The value of 99mTc-MIBI whole body scintigraphy in active and in remission multiple myeloma.

Setting: The study was performed from 2002 through 2003 in the Islamic Republic of Iran.

A preliminary study of neuroSPECT evaluation of patients with post-traumatic smell impairment.

Background: Most olfactory testings are subjective and since they depend upon the patients' response, they are prone to false positive results. The aim of this study was to use quantitative brain perfusion SPECT in order to detect possible areas of brain activation in response to odorant stimulation in patients with post-traumatic impaired smell in comparison to a group of normal subjects.

Methods: Fourteen patients with post-traumatic impaired smell and ten healthy controls were entered in this prospective study.

Semi-quantitative assessment of salivary gland function in patients with differentiated thyroid carcinoma after radioiodine-131 treatment.

Sialadenitis and xerostomia are well-known side effects of high-dose radioactive iodine ((131)Iota) treatment in patients with differentiated thyroid carcinoma (DTC). This study was undertaken to determine salivary gland function semi-quantitatively in patients with DTC given (131)I for the treatment of the thyroid remnant and/or metastases. Thirty-six patients, 11 males and 25 females, mean age 53.

Radiation dose rate and urinary activity in patients with differentiated thyroid carcinoma treated with radioiodine-131; a survey in Iranian population.

The study was undertaken in order to estimate the radiation doses, that patients from Iran who received Na(131)I for the treatment of differentiated thyroid carcinoma (DTC) emit to their environment and also in order to evaluate the instructions given to these patients after being released from the nuclear medicine department. In 29 patients with DTC following thyroidectomy and immediately after the administration of therapeutic Na(131)I for the ablation of the thyroid remnants, the dose rates from the (131)I radioactivity emitted by these patients was measured at 3 meters. Also in these patients the dose rates from the (131)I were measured before they left the nuclear medicine department, at distances of 0.
