positron emission tomography (pet) imaging using 2-deoxy-2-[f-18]fluoro-d-glucose (fdg) has proven valuable in the diagnosis, staging and restaging for many cancers. however, its application for liver cancer has remained limited owing in part to the relatively high background uptake of the tracer in the liver plus the significant variability of the tumor specific uptake in liver cancer among pa...

Introduction: Computed tomography (CT) imaging is the choice of investigation for evaluation of extent of tumor under the mucosa, locally and regionally. This study was undertaken to assess the accuracy of preoperative CT imaging in the staging of carcinoma of the larynx and hypopharynx.   Materials and Methods: In this retrospective study, all cases who were clinically (c) staged T3–T4 and w...

There are many patents for magnetic nanoparticles as tumor resonance imaging enhancers, but the gadolinium complexes commonly used in clinic difficult to target diseased tissues, while nanoliposomes ideal carriers anti-tumor drugs.

in this report, we have presented 18fdg-pet findings of organized hematoma of the maxillary sinus (ohms) that showed an increased fdg uptake in the peripheral rim of the mass with central photopenia. to our knowledge, this is the first case report in the literature reporting fdg-pet/ct findings of ohms. careful interpretation of metabolic (fdg-pet/ct) and anatomic (ct and mri) images should be ...

Tumor vessel co-option is a crucial predictor for tumor invasiveness but easy to ignore in vascular targeting therapy. A high density of located alongside the frontier predicted tendency invasion and regional metastasis. Herein, novel second near-infrared (NIR-II) nanoagent (Coi8DFIC-sorafenib nanoparticles, CS NPs [CS NPs]) was constructed with an organic Coi8DFIC dye sorafenib, which demonstr...

uterine leiomyoma is the most common benign tumor of genital tract. the etiology of myomas is unknown. leiomyoma shows a broad spectrum of radiographic appearances depending on the number, size, and location of the tumor. the diagnostic method for uterine leiomyomas is based primarily on the clinical situation. despite of the varied diagnostic options such as; transvaginal sonography, sonohyste...

Background: Oxytocin (OT) is a paracrine hormone with various biological activities and many sex organs in both sexes, as well as many tumor cells have shown to have related receptors. In this study the development of a receptor imaging tracer for possible tumor imaging has been described. Materials and Methods: OT was successively labeled with [67Ga]-gallium chloride after conjugation with fre...

primitive neuroectodermal tumor (penets) is an uncommon malignancy of bone and soft tissue witch rarely occurs in the kidney. in more than 90% of the cases, the tumor cells relieves a balanced translocation (11; 22) (q24; q12). immunohistochemical staining may be required for diagnosis of penet. the cells of tumor express cd99, vimentin, nse, fl1 but do not express ck, lca, myogenin, and wt1. w...

Introduction: All of the Imaging modalities have advantages and disadvantages alone. So if we want to have the best and perfect image, combining these modalities produces something we desired. PET-MR images consist of morphologic and metabolic data. MRI and PET provide high spatial and contrast resolution and high sensitivity and molecular information respectively. Hybrid PET-...
