Introduction: High-dose radioactive iodine therapy in differentiated thyroid cancer (DTC) may adversely affect the salivary gland function. This study is aimed to evaluate the effect of radioactive iodine (RAI) with dose of 100 mCi in DTC patients compared to lower doses of less than 30 mCi in hyperthyroid cases. Methods: Fifty four patients (13 men and 41 women) age: 42.3±14.3 (21-71) years w...

OBJECTIVE To examine the prevalence of mild cognitive impairment (MCI) and its diagnostic classification in the Cardiovascular Health Study (CHS) Cognition Study. DESIGN The CHS Cognition Study is an ancillary study of the CHS that was conducted to determine the presence of MCI and dementia in the CHS cohort. SETTING Multicenter population study. PATIENTS We examined 3608 participants in ...

Mild cognitive impairment (MCI) patients have a high risk of converting to Alzheimer's disease. The most common diagnostic subtypes of MCI have an episodic memory disorder (amnestic MCI) occurring either alone [single domain (SD)] or with other cognitive impairments [multiple domain (MD)]. Previous studies report increased amplitudes of auditory cortical potentials in MCI, but their relationshi...

using gate’s technique for gfr measurement with gamma camera, the patient is received 5mci of tc-99m-dtpa. by this amount of radioactivity, good quality renal scan is not possible. this study tries to optimize gate’s technique for gfr measurement during routine renal scan (with 10-15 mci). methods and materials: scanning was performed for 60 seconds from samples of tc-99m with activities of 3, ...

BACKGROUND Neuropsychological comparisons between patients with mild cognitive impairment due to Parkinson's disease (MCI-PD) and Alzheimer's disease (MCI-AD) is mostly based on indirect comparison of patients with these disorders and normal controls (NC). OBJECTIVE The focus of this study was to make a direct comparison between patients with these diseases. METHODS The study compared 13 pa...

introduction: in the current study, we evaluated the feasibility of body outlining using tc-99m filled flood source for lymphoscintigraphy imaging. methods: 80 patients were included in the study. sentinel node mapping was done using tc-99m antimony sulfide colloid. for outlining the body a tc-99m filled flood source was used which was placed behind or lateral to the patients for anterior and ...

IMPORTANCE Previous studies suggest cross-sectional associations between a diagnosis of chronic obstructive pulmonary disease (COPD) and mild cognitive impairment (MCI). However, few studies have assessed whether COPD, a potentially modifiable factor, is associated with an increased risk for MCI and whether the relation is specific to the type of MCI. OBJECTIVE To investigate whether a diagno...

OBJECTIVE To measure hippocampal volumes in patients diagnosed as having subtypes of mild cognitive impairment (MCI) relative to those of elderly control subjects and those of patients with Alzheimer disease (AD) using 3-dimensional mesh reconstructions. DESIGN A magnetic resonance imaging volumetric study of MCI subgroups (MCI, amnesic subtype [MCI-A]; and MCI, multiple cognitive domain subt...

Background & Objective:  Mild cognitive impairment (MCI) is a transient state between normal condition and dementia. Available data indicates that coronary artery diseases (CAD) may increase the risk of MCI. Hence, the early detection of MCI can prevent the progression of cognitive decline. Materials & Methods:  A sample of 65 subjects with degrees of CAD was enrolled to the study. For cogniti...
