The aim of this study was to detect additional findings in whole body FDG-PET/CT scan including the brain, calvarium, and scalp (compared starting from base skull) cancer patients determine contributions these results tumor staging treatment protocols.We noted whether related 1359 had a potential modify disease, chemotherapy protocol, radiotherapy surgical management. We identified rates metastatic on according types scanning.We found for malignancy above skull 42 (3.1%), one whom patient...

Bone scintigraphy (BS) and fluorine-18 deoxyglucose positron emission tomography computed ((18)F-FDG-PET/CT) are widely used for the detection of bone involvement. The optimal imaging modality metastases in histological subgroups non-small cell lung cancer (NSCLC) remains ambiguous. aim this study was to compare efficacy (18)F-FDG-PET/C 99mTc-methylene diphosphonate ((99m)Tc-MDP) BS patients NSCLC. Specifically, we compared diagnostic accuracies these techniques evaluating metastasis...

We aimed to evaluate the efficiency of dual time-point fluorodeoxyglucose (FDG) PET/computed tomography (CT) imaging in detecting primary and metastatic lesions gastric cancer.Between May 2019 January 2020, 52 patients with carcinoma were prospectively involved our study. And FDG PET/CT performed patients. Of detected lesions, ones that are better visualized or only appear delayed visually identified. Also, maximum standardized uptake value (SUVmax) intact liver tissue measured early...

Minimally invasive parathyroidectomy (MIP) has become the first line of treatment for primary hyperparathyroidism caused by solitary parathyroid adenoma. In order to increase sensitivity high-resolution ultrasonography (hUS), surgeon performed (SUS) been increasingly used preoperatively. However, a radiologist and performing (RSUS) not usual practice. this study, we aimed evaluate clinical contribution RSUS on MIP.From 2012 2014, total 30 consecutive patients (4 male, 26 female, mean age...

Objectives. The measurement of mucociliary transport velocity by rhinoscintigraphy with Tc-99m-macroaggregated albumin ( 99m Tc-MAA) is reliable measure clearance. aim this study to assess the intratest, interobserver, and intraobserver reproducibility nasal rate (NMTR) measurement. Materials Methods. Twenty-two subjects were evaluated determine intratest a group 35 was examined inter- reproducibility. Rhinoscintigraphy Tc-MAA used NMTR in all subjects. Paired measurements compared using...

This study aimed to determine the efficacy of acoustic radiation force impulse (ARFI) imaging for functional assessment salivary glands by comparing ARFI with gland scintigraphy.We prospectively evaluated 60 parotid (P) and submandibular (SM) 30 patients using scintigraphy elastography. The average pixel uptake excretion fraction (EF) in P SM were determined scintigraphically. degree stiffness at prelemon postlemon stimulation periods measured elastographically ARFI. Changes also calculated...

Coronary artery disease is one of the most common and important health problems in world. Early diagnosis this very to treat before severe myocardial damage occurred. Myocardial perfusion scintigraphy (MPS) computed tomography coronary angiography (CTCA) which evaluates regional arteries, respectively, are reliable non-invasive methods terms disease. In study we aimed compare MPS CTCA based on conventional (CCA). Totally 60 patients were included study. CCA performed 30 patients; rest (30...

SUMMARY OBJECTIVE: This study aimed to determine the thoracic and extra-thoracic extension of disease in patients diagnosed with lung cancer who had whole-body F18-fluorodeoxyglucose positron emission tomography/CT imaging investigate whether there is a relationship between tumor size extrathoracic spread. METHODS: A total 308 were included this study. These first classified as group 1 (SPN 30 mm>longest lesion diameter ≥10 mm) 2 (lung mass (longest ≥30 mm), then same 3 (nodular ≤20 4 >20...

Aims: Microsatellite instability has been determined as an important indicator in selecting chemotherapy drugs colorectal cancer. Within the scope of this research, we aimed to elucidate pathology reports and determine whether metabolic parameters detected by PET/CT differ MSI-positive negative patients. Methods: A total 35 patients were analyzed retrospectively. The patient population consisted who applied Nuclear Medicine Department with a diagnosis colon or rectum cancer, underwent...
