OBJECTIVE Using nuclear medicine imaging, we explored suitable acquisition window parameters for assessing the distribution of iodine-125 radioactive seed implantation. SUBJECTS AND METHODS We studied 30 patients with various tumors (21 of which were liver cancers) who had received iodine-125 radioactive seed implantation and had undergone whole-body scintigraphy. Scintigraphy images were acq...

Introduction : We compared the accuracy of staging by whole body coincidence mode 18F-FDG PET-CT scan with thoracic and abdominal computed tomography scan. Material and Methods : Histopathologically proven newly diagnosed 109 patients (in 12 months) of lung carcinoma underwent whole body (base of the skull to upper third of thigh) FDG PET scan and baseline thoracic and abdominal CT. Results : F...

OBJECTIVE To assess whether FDG PET could localize the recurrent or metastatic lesions in papillary thyroid cancer patients with negative radioiodine scan. METHODS Whole body PET was performed after injecting 370-555 MBq of 18F-FDG in 108 patients, who were suspected of having recurrence or metastasis and whose 131I whole body scans were negative. Recurrence or metastasis occurred in 63 patie...

OBJECTIVE The prognostic values of serum thyroglobulin (Tg) and antithyroglobulin antibody (TgAb) levels, measured immediately before I-131remnant ablation in patients with differentiated thyroid cancer (DTC), have been advocated by some researchers; however, it had controversial outcomes. This study was carried out to examine this dilemma and to check the clinical significance of basal serum T...

introduction: medullary thyroid carcinoma (mtc) is a rare thyroid cancer secreting calcitonin (ct) which is the most sensitive and specific tumor marker for mtc. this type of thyroid cancer is able to metastasize to different body areas including regional lymph nodes, lungs, liver and bone. the aim of this study was to assess the sensitivity and specificity of [99mtc-dmsa (v)] whole body scan (...

Our objective was to determine whether anthropometric measurements of the midarm (MA) could identify subjects with whole body fat-free mass (FFM) depletion. Fifty-five patients (31% females; age: 64.6 ± 9.3 years) with mild/very severe chronic obstructive pulmonary disease (COPD), 18 smokers without COPD (39% females; age: 49.0 ± 7.3 years) and 23 never smoked controls (57% females; age: 48.2 ±...

background: deficiency of attention and concentration is one of great reasons of traffic incidents and it covers between 20 to 50 percent of events due to careless and mindedness. studies show that attention and concentration are considered as one of important cognitive components in safe driving. vibration is an important physical effect in all vehicles. till now has not been any organized stu...

Objective: To assess the value of the diagnostic whole body I scan after thyroidectomy and I ablation. Design: Retrospective analysis of all patients with differentiated thyroid cancer treated in one centre between 1990 and 2000. Results: A total of 153 consecutive patients who underwent diagnostic scanning following ablative therapy were identified. This diagnostic scan was positive in 20 pati...

Segmentation of 3D human body is a very challenging problem in applications exploiting human scan data. To tackle this problem, this paper proposes a topological approach based on the Discrete Reeb Graph (DRG) which is an extension of the classical Reeb Graph to handle unorganized clouds of 3D points. The essence of the approach concerns detecting critical nodes in the DRG thereby permitting th...

Introduction In live multiple mouse whole body imaging, the heart is not the main focus of investigation yet it still presents the usual imaging problems. If the heart is to be resolved temporally by retrospective cine reconstruction, then the spatial resolution of the overall data set must be limited due to the available scan time. Conversely, at the desired spatial resolution of 100-200 um, t...
